No, weight gain hasn’t been reported as a side effect in people taking Ocrevus.
However, in clinical trials, some people taking Ocrevus for primary progressive multiple sclerosis (PPMS) reported swelling in their arms and legs. Sometimes, this swelling can cause weight gain. If you experience swelling while taking Ocrevus, talk with your doctor. They may recommend a medication to help treat this side effect.
If you’re concerned about weight gain that isn’t due to swelling, talk with your doctor. They can recommend ways to maintain a weight that’s healthy for you.
