Can alcohol be consumed while taking Cialis or Tadalafil?
A little alcohol is usually fine with Cialis; heavy drinking lowers blood pressure further and worsens erections.
A small amount of alcohol is usually fine with Cialis (tadalafil), but more than a little is a bad combination: both lower blood pressure, so together they can cause dizziness, headaches or fainting, and alcohol itself works against erections. This article explains how alcohol and tadalafil interact and what is sensible.
It is a topic in our erectile dysfunction and men's sexual health section.
How they interact
Both tadalafil and alcohol relax blood vessels and lower blood pressure. In moderation the combined effect is usually minor, but with heavier drinking the drops can add up, causing lightheadedness, a pounding headache or, rarely, fainting on standing.
Alcohol works against erections
Beyond the blood-pressure interaction, alcohol is itself a depressant that impairs erections — the so-called "brewer's droop". So heavy drinking can cancel out the benefit of tadalafil, leaving a man worse off rather than better.
| Amount | Effect with tadalafil |
|---|---|
| A drink or two | usually fine |
| Heavy drinking | dizziness, worse erections |
| With low blood pressure | higher risk, caution |
What is sensible
Keeping alcohol modest — a drink or two rather than a heavy session — usually avoids problems and preserves the medicine's effect. Drinking plenty of water and not standing up too quickly also help if you do drink.
Who should be more careful
Men with low or unstable blood pressure, heart conditions, or who take other blood-pressure-lowering drugs should be especially cautious, as the combination magnifies the risk. When in doubt, ask a doctor about your specific situation.
The bottom line
Moderate alcohol and tadalafil can coexist, but heavy drinking undermines both safety and performance. The same applies to sildenafil. For the wider safety picture, see Viagra side effects and risks.

A practical rule of thumb
A useful rule of thumb is moderation: a drink or two is generally compatible, while a heavy session undermines both safety and performance. If you do drink, stay hydrated and rise slowly to avoid dizziness. For men with low blood pressure or heart conditions, even modest amounts deserve more caution, so it is worth a quick word with a doctor about your own situation.
The same applies to sildenafil
These principles are not unique to tadalafil. Sildenafil and the other PDE5 inhibitors share the same interaction with alcohol, because they all mildly lower blood pressure. So whichever ED drug you use, the advice holds: keep alcohol moderate, stay hydrated, and be extra cautious if you have low blood pressure or take other vessel-relaxing medicines. Moderation protects both your safety and the result you are hoping for.
