cialis tadalafil and alcohol

Can I Drink Alcohol on Cialis?
According to the manufacturer of Cialis® (tadalafil), drinking large amounts of alcohol while taking this drug is not recommended. Although drinking a little alcohol while on Cialis probably will not cause any problems, significant consumption may cause a drug interaction.

Cialis is a known phosphodiesterase-5 (PDE5) inhibitor which can cause vasodilation (widening of the blood vessels). Combining such drugs with alcohol use can have additive hypotensive effects. Clinical studies show that consuming large amount of alcohol while on tadalafil treatment can lead to significant decrease in blood pressure. People reported symptoms of low blood pressure that include dizziness, and orthostatic hypotension (low blood pressure when in upright position) was also observed. However, both of these substances did not interfere with the pharmacologic effect of each other as well as their metabolism and excretion.

Possible Side Effects
Studies have shown that people who are taking Cialis while drinking large amounts of alcohol can likely experience symptoms that include:
– Dizziness
– Increase in heart rate (tachycardia)
– Low blood pressure, especially in upright position (orthostatic hypotension)
– Headache
These symptoms are due to the increased vasodilation of the blood vessels.

Talking With Your Healthcare Provider
You should talk with your healthcare provider about alcohol consumption and Cialis. You and your healthcare provider understand your situation best. Based on what you want and expect, as well as your current health situation, the two of you can make a shared decision about your intake of alcohol while on this drug. There may also be other medical reasons why you should not consume alcohol.
