Accutane: Stunt Growth?
#1
Posted 31 August 2006 - 03:26 PM
I have heard accutane is like the chemotherapy of acne medications, but I read the thing and it said it may stunt bone growth. I don't care if my skin turns yellow and I have to avoid the sun like a vampire, my main worries in life today are growing taller and becoming clear. Are these things conflicting? Is there anything I'm missing?

This particular effect has not shown up in the clinical trials as far as i know. There are only a few anecdotal reports of premature growth plate closure - if Accutane does cause this, it's crazy rare.

lol i think there's fairly a number of explanations for your stunt in growth, quite possibly it was a coincidence that u happen to stop growing (premature growth spurt?) the same time you took tane. How tall are ur parents?, you should compare yourself to your parents to really see if you have stunted growth. If your dad's 6"7 and ur only 6", then i think there might be a problem.

Skeletal
Bone Mineral Density
Effects of multiple courses of Accutane on the developing musculoskeletal system
are unknown. There is some evidence that long-term, high-dose, or multiple
9
courses of therapy with isotretinoin have more of an effect than a single course of
therapy on the musculoskeletal system. In an open-label clinical trial (N=217) of a
single course of therapy with Accutane for severe recalcitrant nodular acne, bone
density measurements at several skeletal sites were not significantly decreased
(lumbar spine change >-4% and total hip change >-5%) or were increased in the
majority of patients. One patient had a decrease in lumbar spine bone mineral
density >4% based on unadjusted data. Sixteen (7.9%) patients had decreases in
lumbar spine bone mineral density >4%, and all the other patients (92%) did not
have significant decreases or had increases (adjusted for body mass index). Nine
patients (4.5%) had a decrease in total hip bone mineral density >5% based on
unadjusted data. Twenty-one (10.6%) patients had decreases in total hip bone
mineral density >5%, and all the other patients (89%) did not have significant
decreases or had increases (adjusted for body mass index). Follow-up studies
performed in 8 of the patients with decreased bone mineral density for up to 11
months thereafter demonstrated increasing bone density in 5 patients at the
lumbar spine, while the other 3 patients had lumbar spine bone density
measurements below baseline values. Total hip bone mineral densities remained
below baseline (range –1.6% to –7.6%) in 5 of 8 patients (62.5%).
In a separate open-label extension study of 10 patients, ages 13-18 years, who
started a second course of Accutane 4 months after the first course, two patients
showed a decrease in mean lumbar spine bone mineral density up to 3.25% (see
PRECAUTIONS: Pediatric Use).
Spontaneous reports of osteoporosis, osteopenia, bone fractures, and delayed
healing of bone fractures have been seen in the Accutane population. While
causality to Accutane has not been established, an effect cannot be ruled out.Longer term effects have not been studied. It is important that Accutane be given
at the recommended doses for no longer than the recommended duration.
Hyperostosis
A high prevalence of skeletal hyperostosis was noted in clinical trials for
disorders of keratinization with a mean dose of 2.24 mg/kg/day. Additionally,
skeletal hyperostosis was noted in 6 of 8 patients in a prospective study of
disorders of keratinization.6 Minimal skeletal hyperostosis and calcification of
ligaments and tendons have also been observed by x-ray in prospective studies of
nodular acne patients treated with a single course of therapy at recommended
doses. The skeletal effects of multiple Accutane treatment courses for acne are
unknown.
In a clinical study of 217 pediatric patients (12 to 17 years) with severe
recalcitrant nodular acne, hyperostosis was not observed after 16 to 20 weeks of
treatment with approximately 1 mg/kg/day of Accutane given in two divided
doses. Hyperostosis may require a longer time frame to appear. The clinical
course and significance remain unknown.
10
Premature Epiphyseal Closure
There are spontaneous reports of premature epiphyseal closure in acne patients
receiving recommended doses of Accutane. The effect of multiple courses of
Accutane on epiphyseal closure is unknown.
Vision Impairment
Visual problems should be carefully monitored. All Accutane patients
experiencing visual difficulties should discontinue Accutane treatment and have
an ophthalmological examination (see ADVERSE REACTIONS: Special
Senses).
Corneal Opacities
Corneal opacities have occurred in patients receiving Accutane for acne and more
frequently when higher drug dosages were used in patients with disorders of
keratinization. The corneal opacities that have been observed in clinical trial
patients treated with Accutane have either completely resolved or were resolving
at follow-up 6 to 7 weeks after discontinuation of the drug (see ADVERSE
REACTIONS: Special Senses).
Decreased Night Vision
Decreased night vision has been reported during Accutane therapy and in some
instances the event has persisted after therapy was discontinued. Because the
onset in some patients was sudden, patients should be advised of this potential
problem and warned to be cautious when driving or operating any vehicle at
night.

haha yes i know a TON of people (including my dad) who were the tallest people in their class in like, 6th or 7th grade, and then pretty much stopped growing. My Dad was 5'10" in 5th grade and is now 5'11'' at age 52

and by the way, i would definitely not recommend accutane for somebody who only has moderate acne. Especially if your weight lifting. I broke the cartilage in both of my knees from doing simple squats with a relatively light weight and had physical therapy for 9 MONTHS (i started to heal almost immediately after i had got off the accutane. And also, i had never had even a minor injury in my entire life before i went on accutane.). I happened to respond very poorly to accutane, though many people who get the effects only lightly report joint pains and NO ONE is recommended to put stress on their joints with heavy lifting while on the drug.

Regarding your son, what supposedly causes stunting is premature growth plate closure. If Accutane had caused his growth plates to close prematurely he would not have grown at all since then. It's very possible that the stress of the course temporarily stopped his growth much like it tends to temporarily stop hair growth, but that's not "stunting."

It has never shown up in a clinical trial as far as i know. They can't look into the issue because if it is really caused by Accutane and not just a coincidence, it's so rare that it doesn't show up in the sample size used for trials. There is no evidence that this happens at all, only anecdotal reports.
