Find out what drinking too much alcohol while on the drug can mean for your health.

Know the Side Effects

Cialis is the brand name for the drug tadalafil, which is used to treat erectile dysfunction (ED). Men with ED have difficulty getting or maintaining an erection. Cialis is one of several ED medications on the market. It differs from some of the others because it remains in a man’s system longer.

However, as with most medications, Cialis has some side effects. Most of them are fairly minor, such as a stuffy nose or a minor headache or backache. But some side effects can be more serious, especially if Cialis is taken with other drugs. It can also be risky if taken with too much alcohol.

Alcohol Warning

The main concern with alcohol and Cialis is the consumption of excessive amounts of alcohol. Having just a glass of wine or other drink is unlikely to affect Cialis or cause any health risks. But if a man has five or more drinks with Cialis in his system, some heart-related health problems can result.

For example, the combination of excessive alcohol and Cialis can lead to signs of orthostatic hypotension. That’s a condition in which a person stands up after lying down or sitting down and experiences a sudden decrease in blood pressure and dizziness. Symptoms, such as a headache and a faster heart rate, may also result.

A sudden drop in blood pressure can cause fainting. If you faint, you can experience a fracture or other injury.

What Is Vasodilation?

The reason why alcohol and Cialis can combine to cause serious low blood pressure is because both act as vasodilators. Vasodilators are substances that lower blood pressure by relaxing the walls of your blood vessels and opening them wider. Alcohol can do this on its own, though when excessive alcohol consumption is stopped, a spike in blood pressure can occur.

Because Cialis is an effective vasodilator, it can be a risk if taken with other medications, such as alpha blockers, that also lower blood pressure.

More on Alcohol

A drink of alcohol is considered one 12-ounce beer, five ounces of wine, and 1.5 ounces of liquor. The U.S. Centers for Disease Control and other health organizations recommend that alcohol consumption be limited to one drink per day for women and two drinks per day for men. Excessive alcohol consumption can not only lead to interactions with Cialis and other medications, it can lead to drunk driving and other risky behaviors. Alcohol dependence can also lead to trouble with your overall health, as well as with your personal relationships and your job.

If you find yourself having several drinks per day or being unable to go a day without a drink, you should talk with your health are provider or a mental health counselor about your behavior. Long-term alcohol abuse raises your risk of numerous health problems, including heart disease, obesity and early dementia.

Be Smart About Cialis

Cialis is a prescription medication, so before you start taking it, make sure your doctor knows your medical history and your current health status. That includes a list of all medications you take. You should also be honest with your doctor about how much alcohol you consume on a regular basis.

If you notice symptoms such as dizziness or headaches when you drink while also using Cialis, tell your doctor. But remember that alcohol alone can cause those side effects.

In general, moderate alcohol consumption with Cialis is usually safe. But if you want to avoid potentially dangerous side effects, limit consumption to one or two drinks per day, if at all.
