The manufacturer of Cialis (generic name: tadalafil), Eli Lilly, says that having a few drinks with Cialis is unlikely to increase the risks of side effects. However, taking Cialis with alcohol can be harmful if you drink in excess (Eli Lilly, 2008).
So, while you may not need to fully abstain, moderation is key when it comes to drinking while taking tadalafil (Cialis). The Centers for Disease Control and Prevention (CDC) defines moderate drinking as one drink per day for women and two drinks per day for men (CDC, 2019). One drink translates to a 5-ounce glass of wine, a 12-ounce glass of beer, or a 1.5-ounce shot.
