When using medications, it’s essential to know their potential interactions with other substances, such as alcohol. 

Tadalafil is a popular medication sold under the brand name Cialis which is used for treating Erectile Dysfunction (ED) in men. 

But you must know everything regarding combining it with alcohol. 

This article will talk about combining Tadalafil and alcohol.

It will also explore the effects and precautions associated with their combined use.

Can you take Tadalafil and alcohol together

Tadalafil (Cialis), used to treat Erectile Dysfunction, works by dilating the blood vessels to allow for improved blood flow to the penis.

Consuming a single glass of alcohol is unlikely to impact the working of Tadalafil. 

However, taking Tadalafil with excessive alcohol can cause health problems like Orthostatic Hypotension (drop in blood pressure when standing up).

Hypotension can result in Tachycardia. In some cases, this may even result in significant cardiovascular complications.

  • Cialis 20 mg
  • Tadarise 5 mg
  • Vidalista 20 mg
  • This phenomenon may occur due to the vasodilatory properties of Tadalafil and alcohol. 

    Both Cialis and alcohol increase the diameter of the blood vessels, improving the blood flow to the penis, which leads to an erection.

    The dilation of the blood vessel lowers the blood pressure. The interaction of Tadalafil with alcohol leads to a significant drop in blood pressure.

    Tadalafil has a higher possibility of causing Orthostatic Hypotension than other Erectile Dysfunction pills

    This can be because Tadalafil lasts longer than other ED medications.
