Can I drink alcohol while taking effexor (venlafaxine) and gabapentin?

Not recommended. Psychoactive medications can cause significant central nervous system dysregulation when alcohol is consumed. Not only would you experience potential side effects such as dizziness, excess sedation and drops in blood pressure, but also impaired cognitive functioning. This includes poor judgement and disinhibition. Alcohol can also interfere with full efficacy of these medications. Hope this helps.
