What's Allowed While Taking Accutane?

It sounds like you are going to have to make some adjustments while you are on Accutane:

1. avoid alcohol-- Accutane and alcohol both cause liver inflammation.  It is not advisable to take both at the same time

2. While there is no restriction on working out, Accutane may cause muscle aches.  Keep this in mind.

3. Avoid vitamin A while on Accutane.  Accutane is a retinoid which is related to vitamin A.  Taking Accutane is like taking megadoses of vitamin A in terms of the side effects it can have on your body.  Find another protein shake that does not have vitamin A to take while you are on Accutane.

One of Accutane side effects is that it can potentially affect the liver.  Alcohol also affects the liver, so if a large amount of alcohol is consumed, there are two substances in the body concurrently affecting the same organ, which makes damage more likely.  Therefore one should try to avoid alcohol while on Accutane. 

Another potential side effect is that Accutane can make your muscles more sore during workouts, so when starting Accutane, decrease the level of your workout somewhat until you know how sore your muscles get.  Taking Accutane should not stop you from working out, just decreasing the intensity at the beginning and every time the dose increases, until you find your comfort level.

Accutane is a relative of vitamin A, so taking Accutane and vitamin A at the same time may result in an increased risk of side effects.  I would recommend getting a supplement without vitamin A.
