Does ritalin 36 have any side effects? Does it effect filmy legs?

I'm curious when my friend has ADHD and eats Ritalin 36.....He has runny legs he is kinda short at the of 14...
Is it because he's too immature?
Answers:
36 pills? Or Concerta (same as Ritalin) 36mg?

Either way it is the same answer. Methylphenidate (Ritalin) cause weight loss and it can stunt growth.

Nothing to do with maturity. But really intake it is a bad thing. Source(s): I am a 4th year Psychopharmacology/ Pre-med university student and Psychiatric intern. Did a Neurology internship and interned at a Chemical Dependency Rehabilitation Centre
