The Essential Information

Can Definitely Cause Acne: Based on research, common medications that often result in acne include:

  • Corticosteroids
  • Testosterone and other anabolic-androgenic steroids (AAS)
  • Lithium
  • Isoniazid
  • Halogens
  • EGFR inhibitors (EGFR-I)

May Cause Acne: Vitamin B supplements may also cause acne, but the evidence is incomplete.

Might Cause Acne: Finally, a few case reports point toward a possibility that the following medications might also cause acne:

  • Rifampicin
  • Ethosuximide
  • Interferon
  • Olanzapine
  • Some hormonal contraceptives that release progesterone

The Science

Based on the amount of research that links particular medications to acne, we can place potentially acne-causing medications into three categories.

  1. Medications that can definitely cause acne: We have a large amount of evidence linking these medications to acne.
  2. Medications that may cause acne: We have a considerable but insufficient amount of evidence linking these medications to acne.
  3. Medications that might cause acne: We have a small amount of evidence linking these medications to acne.1

Even if someone takes a medication that falls into the first category--medications that can definitely cause acne--this does not necessarily mean that they will develop drug-induced acne. Whether they develop drug-induced acne or not depends on several other factors, including:

  • Dose of medication: If a person takes a smaller dose, he may not experience acne, but may develop acne if he takes a larger dose.
  • Length of time: If someone takes the medication only a few times, he may not experience acne, but may develop acne if he takes it regularly for weeks or months.
  • History of acne: If a patient has experienced acne before, he may be more likely to develop drug-induced acne.2

Drug-induced Acne Factors

Regular Acne Vs. Drug-induced Acne

Regular acne is different from drug-induced acne (acne that is caused by medication) in four ways:

  1. Medication History: Regular acne can develop in a person who has not used any medication. In contrast, drug-induced acne only develops after he has used a medication that can cause acne.
  2. Time of Onset: Regular acne is most common in adolescents (teens) and develops gradually, while drug-induced acne can occur at any age and often begins suddenly.1
  3. Location of Lesions on the Body: Regular acne typically appears on the face, back, chest, and/or shoulders because the sebaceous (skin oil producing) glands located in these areas of the body tend to produce an abundance of sebum (skin oil). Some medications, like AAS and lithium, simply increase a person's already existing tendency to develop regular acne in these areas. However, most medications that can cause acne lead to drug-induced acne, which can appear on the face and neck like regular acne but can also develop in unusual locations - such as the lower legs and the back of the arms.1
  4. Types of Lesions: Regular acne usually produces many different types of lesions, including whiteheads, blackheads, papules, pustules, nodules, and cysts. Medications like AAS and lithium increase a person's existing tendency to develop regular acne, so a person who takes these medications may experience all of these different types of lesions. In contrast, drug-induced acne typically produces only papules and pustules - in other words, reddened bumps on the skin that people commonly call "pimples" and "zits." It is unusual for a person with drug-induced acne to develop comedones (whiteheads and blackheads).1 Because of these differences, drug-induced acne lesions are often called acneiform, meaning "acne-like."

Regular Acne Vs. Drug-induced Acne

Regular Acne Treatments Vs. Drug-induced Acne Treatments

A variety of treatments are available for regular acne. These treatments typically improve it slowly over weeks or months. On the other hand, drug-induced acne does not respond well to regular acne treatments. It does, however, usually clear up gradually after the person stops using the offending medication.

In order to understand how some medications cause acne, we need to review how acne develops.

  1. The skin oil glands (sebaceous glands) begin producing more skin oil (sebum).
  2. Skin pores become clogged, trapping the sebum inside.
  3. The clogged pores become larger because of the trapped sebum.
  4. Acne bacteria C. acnes begins to grow in the clogged pores, feeding on the sebum.
  5. The bacterial growth causes the pores to become irritated and inflamed, meaning that the area becomes red, swollen, and sometimes sore.3

How Acne Develops

Normal Skin and Skin with Acne

Sometimes medications can cause specific subtypes of severe acne, such as:

  • Acne conglobata: This is a rare and particularly severe form of nodulocystic acne, which is a type of acne in which people develop nodules (large, inflamed, painful, firm-to-the-touch lesions) and cysts (large, fluid-filled lesions). People with acne conglobata suffer from lesions on the body and face, and inevitably develop scarring, which can be particularly severe.4
  • Acne fulminans: This type of acne is as severe as acne conglobata, but cause additional systemic (bodily, as the result of medication transferred via the blood) symptoms - such as fever and joint pains4

Acne Conglobata

Acne Fulminans

Let's read about some common medications that have been linked with acne, beginning with the medications that can definitely cause it.

Medications That Can Definitely Cause Acne


Corticosteroids Can Definitely Cause Acne

What They Are: Corticosteroids, not to be confused with anabolic steroids - which people take for bodybuilding - are medications that suppress the immune system. The immune system is the body's natural defense mechanism against infection and disease. Corticosteroids can be taken by mouth, inhaled, injected into a vein, or used as a topical cream or ointment on the face and other areas of the body. Using corticosteroids in high doses can result in so-called "steroid acne." A person who has a previous history of acne is more likely to develop steroid acne, the severity of which depends on how long and at what dose the person uses the corticosteroids.2 The first symptoms of steroid acne are usually inflammatory papules and pustules.4 Months later, these lesions gradually disappear, and so-called "secondary" comedones (whiteheads and blackheads) appear in their place. These are not the kind of comedones that develop in regular acne. Rather, these secondary comedones develop because of repeated damage to the hair follicles (pores) from the previous papules and pustules.5

In people who have asthma and inhale steroids using a mask, steroid acne may appear on the part of the face that the mask covers.1

How They Cause Acne: We do not know exactly how corticosteroids cause acne. Research suggests that they may increase the amount of sebum in skin pores, the same place where acne develops. This may be problematic because C. acnes, which lives in skin pores, obtains its energy from sebum. When the amount of sebum in pores increases, the number of C. acnes also increases - which can lead to inflammation. This is when pimples form.4

Drug-induced Acne Caused by Corticosteroids

Treatment of Steroid Acne: Steroid acne usually disappears gradually after patients stop using corticosteroids. However, sometimes they need to continue using them - for example, if they have asthma. In that case, their doctor may prescribe an acne treatment for ongoing use.2

Anabolic-androgenic Steroids

Anabolic-androgenic Steroids AAS Can Definitely Cause Acne

What They Are: Androgenic steroids are male sex hormones that are artificially synthesized in a laboratory. The structures of a number of AAS are similar to that of testosterone,7 a male sex hormone that is also found in females in small amounts. The anabolic portion of "anabolic-androgenic steroids" means that these steroids can be used to "bulk up" - that is to say, to increase muscle mass. Thus, AAS are the type of steroids that bodybuilders and athletes employ when looking to enhance their performance. Doctors may prescribe AAS to treat muscle atrophy (wasting), and small doses can also treat hereditary angioedema (swelling of the deeper layers of the skin that runs in families). When it comes to the substance itself, doctors sometimes prescribe testosterone - an anabolic-androgenic steroid - to extremely tall boys to prevent further growth in height, but research shows that about 1 - 2% of these boys develop acne fulminans.2

Acta Dermato-Venereologica

For example, a study that was published in 1992 in the journal Acta Dermato-Venereologica examined 176 Norwegian teen boys who received testosterone injections to stop growth in height. The researchers compared these boys to 23 boys who were untreated, and they found that those who received testosterone experienced a clear increase in acne one to eight weeks after the treatment. The acne lesions developed on the face and trunk (torso) and were severe in some of the boys - for example, there were four cases of acne fulminans.5

A main place that women produce testosterone is the ovaries, so doctors also occasionally prescribe testosterone treatment to women whose ovaries have been surgically removed. However, this therapy is controversial in women. Some studies report that testosterone replacement therapy causes acne in up to 38% of women, but other studies report numbers as low as 5%.2

How They Cause Acne: Scientists and doctors now understand the role of testosterone and other androgens in the development of acne. These male sex hormones increase the production of sebum. This is a key step in the development of acne. In addition, like corticosteroids, high doses of AAS can cause an increase in the amount of sebum in the skin. When this occurs, the number of C. acnes also increases, potentially leading to the inflammation seen in acne pimples. In this way, high doses can cause acne in both males and females or make pre-existing acne worse, particularly in females. If a person who already has acne takes high doses of AAS, the sebaceous glands in his/her skin may increase in size dramatically and begin producing more sebum. He or she may also experience alopecia (hair loss) as a side effect of the medications. In addition, they can cause acne fulminans or acne conglobata.2

Drug-induced Acne Caused by Anabolic-androgenic Steroids - Acne Fulminans and Acne Conglobata.

Treatment for Acne Caused by AAS: Once you stop using AAS, the acne may gradually disappear. However, in 30 - 60% of women who develop acne due to them, the acne does not clear up after ceasing use. In such cases, or for people who need to continue using AAS, doctors may prescribe the topical acne treatment of retinoids.2


Lithium Can Definitely Cause Acne

What It Is: Lithium is a mood stabilizer that doctors prescribe for various psychiatric conditions, such as depression, bipolar disorder, and schizophrenia. Lithium can make existing acne worse or cause acne in people who have never had acne and sometimes causes acne conglobata. Males are somewhat more likely than females to develop acne due to lithium.2

How It Causes Acne: In some people, even small doses of lithium can cause acne - but typically, people develop acne when large amounts of lithium build up in the body. When lithium accumulates in the skin, it can damage skin cells. Damaged skin cells can clog skin pores, increasing the likelihood of acne to develop. Scientists also speculate that lithium may trigger inflammation in the skin.2,5

Drug-induced Acne Caused by Lithium

Treatment of Acne Caused by Lithium: When it comes to acne due to lithium, a potential roadblock presents itself with the medication called isotretinoin, commonly known as Accutane®, which is approved to treat severe cases of acne. This roadblock is that about one percent of people who take isotretinoin may experience depression as a side effect, which would defeat the purpose of taking lithium in the first place.1 Therefore, if you develop acne as a result of taking lithium, your doctor may hesitate to prescribe isotretinoin to you.

Tetracyclines, a class of oral antibiotics that can treat acne, are also not an option for treating acne caused by lithium, because the combination of tetracyclines and lithium can be toxic to the body. As a result, your psychiatrist may recommend replacing lithium with another mood stabilizer which does not cause acne - or if you continue to take lithium, your dermatologist may suggest a different acne therapy.1


Isoniazid Can Definitely Cause Acne

What It Is: Isoniazid is one of the main medications for the treatment of tuberculosis (a bacterial disease that affects the lungs). According to two large studies, approximately 1.4 - 2.5% of people who take isoniazid develop acne - usually after taking the drug over a long period of time2 - and taking it with other tuberculosis drugs may increase your chances.

One study of 2600 people found that among people who took isoniazid in combination with aminosalicylic acid, another tuberculosis medication, 16% developed acne.4

How It Causes Acne: We do not yet know how isoniazid causes acne. Research suggests that in some people, isoniazid tends to build up in the body, and these people may be more likely to develop acne due to it.

Drug-induced Acne Caused by Isoniazid

Treatment of Acne Caused by Isoniazid: In most cases, once someone stops taking isoniazid, her acne will gradually disappear.2


Halogens Can Definitely Cause Acne

What They Are: Halogens are medications that contain the following chemicals: iodides, bromides, and/or chlorides. They are part of:

  • Many asthma medications, such as potassium iodide (Quadrinal®) and (Theophylline Ki).
  • Some expectorants (cough medicines), such as potassium iodide.
  • Some vitamin supplements, such as supplements that contain kelp and many multivitamins.2

Bromides, specifically, are found in:

  • Some sedatives, such as potassium bromide.
  • Some cold remedies, such as the oral medication dextromethorphan hydrobromide (Bromfed DM®) and the nasal spray compound ipratropium bromide.2
  • Some medications for treating ulcers, such as mepenzolate bromide.
  • Some medications for treating the muscle disease myasthenia gravis, such as pyridostigmine bromide and prostigmin bromide.

Halogens often cause acne. Iodides and bromides are especially likely to cause acne or worsen existing acne, but iodides tend to cause more severe acne than bromides do.2 Acne due to halogens usually consists of comedo-like lesions and yellow cysts on the face.1

How They Cause Acne: We currently do not know how halogens cause acne.

Drug-induced Acne Caused by Halogens

Treatment of Acne Caused by Halogens: Once a person stops using medications containing halogens, his acne should gradually disappear.

EGFR inhibitors

Epidermal Growth Factor Receptor EGFR Inhibitors Can Definitely Cause Acne

What They Are: Epidermal growth factor receptor (EGFR) inhibitors are a class of drugs for treating cancer, and they include cetuximab and erlotinib. As many as 85% of patients who take these drugs develop acne. More than 50% of people start to see acne after just one week of taking EGFR-I. Unlike regular acne, acne caused by EGFR-I can also appear on the lower legs and the back of the arms, and the breakouts typically do not include comedones.2,3

How They Cause Acne: EGFR-I block the normal life cycle of skin cells, leading to clogging of skin pores. In addition, they speed up inflammation of the skin pores - so if acne has already started to form, these drugs will speed up the process.2

Drug-induced Acne Caused by EGFR Inhibitors EGFR-1

Treatment of Acne Caused by EGFR-I: Acne caused by EGFR-I, just like regular acne, can be treated with a variety of therapies. Treatment, however, is nonspecific. The lesions are known to respond to the regimens used in the standard treatment of acne, including commonly used anti-acne medications.8


Medications That May Cause Acne

Vitamin B Compounds

Vitamin B Compounds May Cause Acne

What They Are: Vitamin B compounds are vitamins that are present in some foods and can also be taken as supplements. Vitamins B6 and B12 may cause acne, and almost all known cases of acne that are thought to be due to vitamin B compounds have occurred in women.2 Vitamin B12 may cause acne or exacerbate existing acne only at high doses, such as 5 - 10 milligrams per week. When it comes to vitamin B6, we do not know what doses may cause acne.2 On average, acne may appear about two weeks after a person begins using vitamin B compounds.1

How They May Cause Acne: We do not know how vitamin B compounds may cause acne. Some scientists have suggested that these vitamins may irritate the skin pores, causing inflammation.2

Drug-induced Acne Caused by Vitamin B Compounds

Treatment of Acne Caused by Vitamin B Compounds: Acne that may be caused by vitamin B compounds usually disappears gradually once someone stops taking the supplements.2

Medications That Might Cause Acne

Several common medications might cause acne, based on a small number of case reports. Because there is little research evidence linking these medications to acne, we do not know how they potentially cause acne or how the acne should be treated.

Hormonal Contraceptives That Release Progesterone

Hormonal Contraceptives That Release Progesterone Might Cause Acne

Oral contraceptives (birth control pills) containing female hormones normally help to clear up acne in females. These pills typically contain both estrogen and progesterone, the two main female sex hormones. However, some birth control devices that only contain progesterone might occasionally cause acne in some females. These include:

Intrauterine Devices (IUDs) That Release the Female Sex Hormone Progesterone. Some women develop acne one to three months after starting to use an IUD that releases hormones. In these cases, the acne might appear on the jaw and back and consists of papules.4,5

Implants, Such as Implanon®, Which Releases Progesterone Up to 26.8% of women using Implanon® might develop acne, although not all studies agree on these numbers.5

Drug-induced Acne Caused by Hormonal Contraceptives That Release Progesterone


Rifampicin Might Cause Acne

Rifampicin is a drug for treating tuberculosis, and doctors usually prescribe it in combination with isoniazid. Only one report, published in 1974, links rifampicin to acne:

American Journal of Clinical Dermatology

The report describes a number of African patients who received rifampicin with another drug to treat tuberculosis, and developed acne on the face, shoulders, and back after five weeks. The authors found that the acne resolved after the patients stopped taking rifampicin, even though they continued to take the other medication.5

Drug-induced Acne Caused by Rifampicin


Ethosuximide Might Cause Acne

Ethosuximide is a medication for treating epilepsy (seizure disorder). Only one case report, published in the European Journal of Dermatology in 2017, links the drug to acne:

European Journal of Dermatology

The report describes a 20-year-old Italian girl who had never had acne, but who developed acne after treatment with ethosuximide. The girl experienced papules and pustules on the chest, back, forehead, and neck that were intensely itchy.6

To treat the acne, the girl's doctors reduced her ethosuximide dose and also prescribed an antihistamine (antiallergy) medication for the itching and a topical antibiotic. This treatment was effective, and the acne gradually disappeared.6

Drug-induced Acne Caused by Ethosuximide


Interferons are proteins the human body naturally produces as a defense against viruses. Doctors also sometimes prescribe interferons to help treat viral infections such as hepatitis or immune-system-related disorders like multiple sclerosis. There are at least 20 different types of interferons.

One case report, published in the Indian Dermatology Online Journal in 2016, links a type of interferon called interferon-alpha-2a to acne:

Indian Dermatology Online Journal

The report describes an 18-year-old girl with a history of occasional acne who developed a very severe form of acne called acne fulminans after treatment with interferon-alpha-2a for hepatitis B. The girl's symptoms improved after she stopped interferon treatment and began to take a low dose of isotretinoin (Accutane®). The case report authors wrote, "The association of interferon and [acne fulminans] is not reported in [the] literature so far to the best of our knowledge."9

Another case report, published in the Brazilian journal Anais Brasileiros de Dermatologia in 2011, links a different type called interferon-beta-1b to acne:

Anais Brasileiros de Dermatologia

The report describes a 32-year-old Caucasian female with no previous history of acne who developed acne-like lesions due to treatment with interferon beta-1b for her multiple sclerosis. The acne-like lesions appeared on her face, neck, and arms. The lesions disappeared after she stopped treatment with interferon and completed a 4-week course of antibiotic treatment prescribed by her doctor.10

Drug-induced Acne Caused by Interferon


Olanzapine is an antipsychotic drug used to treat conditions like schizophrenia. One case report, published in the Indian Journal of Psychological Medicine in 2019, links olanzapine to acne:

Indian Journal of Psychological Medicine

The report describes a 25-year-old woman who developed acne-like lesions on the face after starting treatment with olanzapine for her schizophrenia. The authors wrote, "There is no previous case report describing...acneiform [eruptions] with olanzapine exposure in schizophrenia."11

Drug-induced Acne Caused by Olanzapine


The table below summarizes all the common medications we have looked at and their link with acne.

According to a 2020 article in StatPearls, an online educational publication for doctors, "Drug-induced acne...can occur due to...anticonvulsants like phenytoin, antidepressants, the antipsychotic olanzapine...antituberculosis drugs like INH, thiourea, thiouracil, disulfiram, corticotropin, antifungals like nystatin and itraconazole, hydroxychloroquine, naproxen, mercury, amineptine, chemotherapy drugs...Antibiotics like penicillins and macrolides...co-trimoxazole, doxycycline, ofloxacin, and chloramphenicol."12

Anais Brasileiros de Dermatologia

According to a 2013 article in the Brazilian journal Anais Brasileiros de Dermatologia, "Drug-induced acne, or drug-induced acneiform eruption, is an adverse effect of...thyroid hormones...antibiotics (tetracycline and streptomycin)...antiepileptic drugs (phenobarbital and hydantoin derivatives), cyclosporin A, antimycotics, gold salts, isotretinoin, clofazimine."13

Archives of Dermatology

A 2009 article in the journal Archives of Dermatology stated, "Nodulocystic acne may be induced by the use of cyclosporine in children as well as adults."14

Acta Biomedica

A 2019 article in the journal Acta Biomedica stated, "Acneiform eruptions...occur with iodides, bromides, adrenocorticotropic hormone...actinomycin D, and phenytoin."15

The Bottom Line

Research shows that common medications, such as corticosteroids, anabolic-androgenic steroids (AAS), lithium, isoniazid, halogens, and EGFR inhibitors (EGFR-I), definitely can cause acne. Though the evidence is scanty, the same may be true of vitamin B supplements. Lastly, some case reports suggest that interferon, olanzapine, rifampicin, ethosuximide, and other hormonal contraceptives which release progesterone potentially bring about acne.
