Side effects of Kamagra Oral Jelly

Even the most carefully tested medications might have unwanted side effects sometimes. One example is the prescription medicine Kamagra Oral Jelly which treats Erectile Dysfunction (ED).

Kamagra contains Sildenafil, the same ingredient present in Viagra. Though it may be effective in improving sexual performance, it is essential to be aware of its potential side effects. 

This article explores the various side effects of Kamagra Oral Jelly and how you can manage them.

Common side effects of Kamagra Oral Jelly

Kamagra, used to treat Erectile Dysfunction, has a few common side effects, which may occur in 1 out of 100 people. These include headaches, dizziness, stuffy nose, and indigestion.

Generally, Kamagra, containing Sildenafil, is well-tolerated. A low dose of Sildenafil is less likely to cause side effects. 

You may experience Sildenafil side effects with a high dose of 100 mg. But since Kamagra is intended for short-term use, its side effects are mild and short-lived.

Let us discuss the four common side effects of Kamagra Oral Jelly 100 mg:



People may experience a headache after taking a Kamagra 100 mg Oral Jelly. This side effect is not a cause for concern and disappears after a while. 

According to FDA data, around 16% to 28% of users report experiencing headaches after taking Sildenafil. 

Research claims that Sildenafil, or its brand-name Viagra, can induce migraine headaches in users.

A common reason for experiencing headaches after taking Kamagra is dehydration. Be sure to consume plenty of water before taking Kamagra.

Hot flushes

FDA data also found that 10% to 18% of people who took Sildenafil experienced flushing. 

Sildenafil works by increasing blood flow in the penile arteries. But it may also increase blood flow in other parts of the body.

This may dilate the blood vessels near the surface of your skin, causing it to appear red and warm.

Ask a doctor to lower your dosage if you experience this side effect. 


Nausea is another side effect of Sildenafil, but less common. It affects 2% to 3% of users. In a four-year study on Sildenafil use with 979 participants, only one experienced nausea. 

Nausea is a mild effect of Kamagra. It usually goes away once the medicine drains out of the body. 

Avoid having spicy food before taking Kamagra to prevent this side effect.

Consider alternative treatments if you experience significant side effects or if Kamagra is not effective for you. Your healthcare provider may suggest alternative treatments for ED, such as other medications or lifestyle changes.


A 2018 paper suggests that indigestion is one of the most reported side effects of Sildenafil.

Indigestion, also known as Dyspepsia, causes bloating and stomach pain. You may take an Antacid or visit a doctor if the symptom bothers you.

Other mild side effects of Kamagra include stuffy nose, dizziness, light sensitivity, and back pain.

All these side effects are easily manageable. Visit a doctor if your symptoms persist.
