Question: Roaccutane - missing period not pregnant

 nfs197 - Fri Apr 03, 2009 4:22 am

Hello. I'm a 23 year old female who have been taking Roaccutane for 3 months now. I started with a 20g dose daily for the first month then moved up to 40g the next 2 months. My skin is starting to clear up now but I didn't have the worst acne in the first place. My problem is with one side effect which I have searched online for but didn't find at any website I checked. I didn't have my period for 2 months. Just once, a week after I started the treatment. I didn't have unprotected sex for 3 and a half months so I'm sure I'm not pregnant but to be even more sure I took many pregnancy tests, last one yesterday, and I am not pregnant. I used to have my preiod regularly EVERY 25 days. I gained weight and my mood swings are getting out of hand. My doctor said it's normal but I didn't find anything about missing periods as a side effect online. Is it normal? Can I just stop taking Roaccutane or are there steps I should follow?

User avatar Hello,
The important thing is to be sure you are using reliable contraceptives while taking this drug. But, each person reacts differently so just because it has not been listed as a common side effect doesn't mean it can't happen. Also, you could be having other hormonal fluctuation that caused the missed periods - not necessarily caused by the medication. You do not need to have a period to be healthy and normal so no need to discontinue the medication just in order to resume periods. It's just pregnancy we need to guard against - lack of periods is not a concern and will probably self-regulate in time. If in doubt, repeat the pregnancy test next week.

Best wishes.
