How to use it:

Minocycline is an oral treatment. Only the extended-release tablet or capsule is prescribed for the treatment of acne and is taken once a day. 

When taking minocycline, drink a full glass of water. It is better to take minocycline with food, as this lowers the risk of irritation or ulcers in the throat. 

Capsules and tablets should be swallowed whole. Do not break, crush, or chew the tablets or capsules. 

If your acne does not improve or gets worse after 12 weeks, contact your physician. 

Follow the instructions on your prescription carefully and use minocycline exactly as prescribed by your physician. Do not change the dose or the frequency of your medication. If you have any questions about the medication or the prescription, ask your physician or pharmacist. 

Be aware of: 

  • Before using minocycline, let your physician or pharmacist know if you are allergic to minocycline, doxycycline, tetracycline, demeclocycline, or any of the other ingredients in the capsules or tablets.
  • Tell your physician that you are taking minocycline before any medical tests. Minocycline may affect the results of some medical tests.  
  • Before using minocycline, inform your physician about the prescription and non-prescription medications, vitamins, nutritional supplements, and herbal products you are using/taking. You will find a complete list of drug interactions below.
  • Beware that the following medications interfere with minocycline making it less effective: magnesium, aluminium or calcium, calcium supplements, zinc or iron products, and laxatives containing magnesium. Minocycline should be taken 2 hours before or 6 hours after taking these  medications.
  • Before using minocycline, inform your physician if you currently suffer from  or have ever suffered from lupus (an inflammatory disease in which the immune system attacks certain tissues such as skin, joints, blood, and kidneys), asthma, intracranial hypertension (increased pressure in the skull), diarrhea, kidney or liver disease, or any infections.
  • Minocycline may reduce the effectiveness of hormonal contraceptives such as birth control pills, patches, rings or injections. To ensure adequate contraception , ask your physician about other forms of birth control, including condoms, diaphragms, or a contraceptive foam or jelly. 
  • Minocycline may make your skin more sensitive to sunlight so avoid unnecessary direct or prolonged exposure to sunlight, especially between 10am and 3pm, and wear protective clothing, sunglasses and sunscreen (with an SPF of at least 15) while taking minocycline. Do not use a sunlamp or tanning bed. Inform your physician if you develop a  skin rash, itching, redness or other discoloration of the skin, or a severe sunburn after exposure to the sun. 
  • Minocycline may cause darkening of your skin, nails, eyes, teeth, gums, or scars. 
  • Minocycline may cause dizziness or lightheadedness, so do not drive a car or operate heavy machinery until you are sure that these symptoms do not occur. 
  • If you are using minocycline and are pregnant or are planning to become pregnant, talk to your physician about using minocycline during pregnancy because minocycline can harm the fetus. Minocycline use during pregnancy can cause permanent staining of the teeth in the baby. 
  • In males, minocycline may affect the formation of sperm cells. 
  • If you are using minocycline and are breastfeeding, talk to your physician about using minocycline during this period.
  • If minocycline was prescribed for acne, you can continue your regular diet unless your physician advises otherwise. However, some evidence suggests that dairy may increase the risk of certain side-effects. Talk to your physician about your diet when on minocycline. 
  • Do not share your medication with anyone else. 
  • Keep your regular appointments with your physician to track your response to minocycline.

Inform your physician or pharmacist about all the prescription and nonprescription medications, vitamins, nutritional supplements, and herbal products you are taking or plan on taking before starting minocycline.
