"I took Effexor XR (extended-release) and I vomited. I'm on 37.5mg. Should I take a second dose?"

If you have vomited after taking your medication, it is best to wait and not take another dose. The timing of when you vomited in relation to when you took the medication will determine whether or not you should take another dose. It is important to consult with your pharmacist to get specific recommendations for your medication in case of vomiting or missing a dose. Taking a double dose could increase the risk of experiencing unwanted side effects.
