Summary

What this interaction means in plain words
Methylphenidate transdermal and Vigabatrin have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Why it happens
No pharmacokinetic mechanism is established; a possible pharmacodynamic effect on seizure threshold is theoretical.
What to do
No dose adjustment of vigabatrin is needed. Monitor seizure frequency when methylphenidate is started or its dose changed.
What to ask your pharmacist
- Is there anything I should notice while taking both?
- Do I need to tell my doctor at the next visit?
