Sildenafil, known by its brand name Viagra, is used for treating Erectile Dysfunction (ED) in men. 

It belongs to the Phosphodiesterase Type 5 (PDE5) inhibitors group of medicines. These medicines work by increasing the blood flow toward the penis. 

While Sildenafil has proven to be an effective solution for ED, it is crucial to understand its potential side effects to ensure safe usage. 

In the article below, we delve into the various Sildenafil side effects and provide valuable insights about their severity.

Common side effects

Sildenafil, used to treat Erectile Dysfunction, may lead to several common side effects.

Headache

One of the most frequently reported side effects of Sildenafil is a headache. 

This occurs due to the medicine’s ability to expand blood vessels and increase blood flow throughout the body.

Flushing

Many users have experienced flushing or redness of the face and neck after taking Sildenafil. 

This happens due to the dilation effect caused by the medicine on the blood vessels, leading to increased blood flow to the penile region.

Indigestion

Sildenafil can occasionally cause indigestion, acid reflux, or an upset stomach. These effects are generally mild and can be avoided by taking the medication with light meals.

Nasal congestion

Nasal congestion – side effect

Some individuals may experience nasal congestion or a stuffy nose due to Sildenafil use. 

This happens due to the medicine’s effect on blood vessels in the nasal passage.

Rare side effects

Although rare, some side effects associated with Sildenafil may be more severe than the common ones.

They may occur if you take more than the recommended Sildenafil dosage.

Warning:
Even though these side effects are rare yet you must consult a doctor immediately if you experience any of these.

Immediate medical attention is important if you encounter any of the following symptoms

Vision changes

Sometimes, Sildenafil can cause visual disturbances, such as blurred vision, color vision changes, or light sensitivity. 

If you notice any of these changes, consult a doctor immediately.

Priapism

Priapism is a prolonged and painful erection lasting more than four hours. 

Although uncommon, it is considered a medical emergency and requires immediate treatment to avoid potential complications.

Hearing loss

Although rare, sudden hearing loss or changes in hearing have been reported in some individuals using Sildenafil. 

If you experience any hearing-related issues, consult a doctor right away.

Sildenafil drug interaction

While Sildenafil is generally safe and well-tolerated when taken as prescribed by a doctor, some people should avoid it.

The Sildenafil oral tablets can interact with other medications, vitamins, or herbs that an individual may be using concurrently. 

This can be dangerous and can either enhance the side effects of the medicine or even cause other serious side effects.

This can also hinder the functioning of the medicine or even make it ineffective.

Sildenafil can interact with medicines that contain Nitrates or alpha-blockers causing a dangerous and sudden drop in your blood pressure.

Apart from medicine interactions, Sildenafil can also react with certain food items such as grapefruit juice.

Grapefruit juice can slow down the working of Sildenafil Citrate and even enhance its side effects. 

In addition, it is advisable to avoid consuming alcohol when taking Sildenafil as it may lead to a dangerous drop in blood pressure.

To avoid these potential interactions, it is recommended to consult a doctor. 

A doctor can oversee and manage all your prescribed medication dosages.
