Julian Carter


sildenafil and alcohol

Alcohol consumption may have several side effects on our health. 

One of these side effects can be Erectile Dysfunction (ED).

Alcoholism reduces blood flow to the penis, resulting in Erectile Dysfunction in males.

Erectile Dysfunction affects a man’s ability to get and maintain an erection.

Sildenafil, Viagra’s principal active ingredient, helps improve blood flow to the penile area. 

Now, Sildenafil might interact with food and beverages like grapefruit, grapefruit juice, and alcohol.

Let’s take a closer look at how alcohol might effect the working of Sildenafil and influence your health.

Alcohol can affect the Central Nervous System (CNS), responsible for sending sensory data to the brain.

Alcoholism can impair your cognition, motility, and CNS reaction time.

By delaying brain-to-penis communication, alcohol lowers penile sensitivity. Hence, consuming alcohol can cause ED, or Erectile Dysfunction.

Erectile Dysfunction is commonly treated with PDE5 inhibitors like Sildenafil (Viagra), Tadalafil (Cialis), and Vardenafil (Levitra).

However, it is not safe to take medicines like Sildenafil with alcohol.

Alcohol can increase the risk of side effects of Sildenafil, such as low blood pressure and dizziness.

    Sildenafil medications such as Cenforce 100 work by relaxing the blood vessels to allow for better blood flow to the penis, leading to an erection in response to sexual stimulation.

    Alcohol and Sildenafil may have an excessive vasodilatory impact when used together.

    By enlarging the blood vessels, they help in lowering the blood pressure.

    Alcohol dilates blood vessels, potentially increasing blood flow, while Sildenafil enhances blood flow by relaxing smooth muscles and increasing vasodilation.

    Mixing the two may worsen the side effects of Viagra, potentially leading to a dangerous drop in blood pressure.

    Mixing Sildenafil with alcohol in a moderate amount is not dangerous and may improve sexual performance.

    However, it may be risky to combine a high intake of alcohol with Sildenafil. 

    The vasodilatory effects of alcohol and Sildenafil can lead to a sudden drop in blood pressure when taken together. It can lead to Orthostatic Hypotension.

    Hypotension may cause your heart to beat faster. Further, these might lead to serious heart issues.

    Additionally, some side effects can occur due to the combination of Sildenafil and alcohol. 

    The side effects include:

    • Headache

    Combining Sildenafil suspension and alcohol: effects and precautions

    Sildenafil suspension is used to treat Pulmonary Arterial Hypertension (PAH), a condition that increases blood pressure in the lungs.

    The active ingredient in Sildenafil suspension is Sildenafil, which belongs to a group of PDE5 inhibitors.

    Sildenafil suspension, commonly used for Erectile Dysfunction, should not be mixed with alcohol.

    Sildenafil (Viagra) is one of the most popular medicines to treat Erectile Dysfunction in men. 

    By enlarging the blood vessels in the lungs, Sildenafil suspension lowers blood pressure in the lungs.

    Mixing Sildenafil suspension with alcohol can further decrease blood pressure.

    Low blood pressure leads to a higher risk of fainting or experiencing cardiovascular complications. 

    It is crucial to prioritize safety and follow medical advice by abstaining from alcohol while taking Sildenafil suspension.

    Therefore, consuming Sildenafil with alcohol while treating ED can harm you.


    In conclusion, combining Sildenafil and alcohol can pose significant risks to one’s health.

    Both substances can affect blood pressure and cardiovascular functions of our body.

    Sildenafil and alcohol’s combined use may worsen these effects, leading to adverse outcomes.
