Kamagra: uses, risks and alternatives explained
Medically reviewed by
Dr Kathryn BasfordLast reviewed: 12 Feb 2026
Kamagra is a medication primarily used to treat erectile dysfunction (ED), a common condition where you struggle to get and/or keep an erection hard enough for sex. Kamagra contains sildenafil, the same active ingredient found in Viagra and it is available in several forms, including tablets and oral jelly.
Despite its widespread use, Kamagra is unlicensed in many countries, including the UK. This means it is not regulated by the UK’s Medicines and Healthcare products Regulatory Agency (MHRA).
In this guide, we’ll discuss the uses and risks associated with Kamagra. You’ll also learn about regulated and licensed alternatives for treating erectile dysfunction.
What is Kamagra?
Kamagra is a brand name for a range of unlicensed sildenafil products used to treat erectile dysfunction. These products are not regulated by the UK’s Medicines and Healthcare products Regulatory Agency (MHRA). This means it is illegal to sell or buy them. It can be dangerous to take.
Kamagra can be found in a few different forms:
Kamagra tablets
Kamagra tablets contain sildenafil, which helps relax blood vessels in the penis to increase blood flow. This helps with achieving and maintaining an erection during sexual activity.
Flavoured oral jelly
Kamagra Oral Jelly works the same way as the tablets but these dissolve quickly in the mouth, allowing for faster absorption. They typically take effect within 15 to 30 minutes, making them popular with those who prefer not to swallow pills.
Effervescent tablets
Effervescent Kamagra tablets dissolve in water, creating a fizzy drink that speeds up the absorption of sildenafil. This may provide a quicker onset of action compared to the traditional tablets.
Combination tablets (Super Kamagra)
Super Kamagra combines sildenafil, which treats erectile dysfunction, and Dapoxetine, which addresses premature ejaculation. Together, they aim to enhance both erection quality and ejaculatory control. However, it's important to be aware that this combination has not been extensively studied or regulated.
Ultimately, each form of Kamagra works in the same way: it increases blood flow to the penis to help men achieve an erection during sexual activity. However, it is important to remember that Kamagra is not licensed in the UK.
How does Kamagra work?
Kamagra is used to treat erectile dysfunction. It does this by improving blood flow to the penis, helping men with erectile dysfunction get and maintain an erection. It is the active ingredient, sildenafil, that does this.
➤ When a man is sexually aroused, the body releases a chemical (nitric oxide) that helps widen the blood vessels throughout the body. However, there is another enzyme (phosphodiesterase type 5, or PDE5) that can stop this process, making it harder to get an erection. Sildenafil blocks that enzyme (PDE5), allowing the blood vessels to stay relaxed and blood to flow more easily, leading to a firmer erection when sexually stimulated.
Kamagra requires sexual stimulation to work – it will not cause an erection on its own. By enhancing blood flow, Kamagra helps men with ED achieve and maintain an erection during sexual activity.
Does Kamagra work for women?
Kamagra is not approved or recommended for use by women. While the active ingredient, sildenafil, can improve blood flow, it is designed exclusively to treat erectile dysfunction in men.
There is no evidence to suggest Kamagra is effective for women, and using it without medical supervision could lead to unintended side effects or health risks.
➤ If you are a woman experiencing sexual health or arousal concerns it is recommended that you consult with your GP for appropriate treatment options.
Is Kamagra safe?
No, Kamagra is not safe. There are several key reasons why Kamagra should be avoided.
"Kamagra is not a safe or regulated option for treating erectile dysfunction. While it may seem like a quick fix, using unlicensed medications like Kamagra can pose serious health risks. Always consult with a healthcare provider to ensure you’re using a safe and appropriate treatment for your condition." – Dr Kathryn Basford, Online Doctor.
Health risks
Kamagra is unlicensed and has not undergone official safety testing. As a result, you cannot be sure of the ingredients, dosages or overall quality. The amount of sildenafil (the active ingredient) may vary from what is stated on the packaging, or it could even contain other unregulated substances that could harm your health. Without proper safety checks, Kamagra presents a significant risk.
Criminal risk
Kamagra is not approved for use in the UK. This means that buying or selling Kamagra is illegal, and doing so could result in a fine or even prosecution. It’s important to only use medications that are prescribed by a licensed healthcare provider to avoid legal consequences.
Unpleasant side effects
Kamagra Oral Jelly contains 100mg of sildenafil, which is the maximum daily dose recommended for severe erectile dysfunction. However, most men will start with a lower dose, and doctors adjust it based on specific needs and how well the body responds to the medication.
Starting at the maximum dose without medical supervision can increase the risk of side effects, including:
- headaches
- dizziness
- nasal congestion
- stomach problems
- vision issues
- feeling of fullness
Taking too much sildenafil, especially if you have certain health conditions or take other medications, can cause a dangerous drop in blood pressure. This is especially risky for men who take nitrates for heart conditions.
Impurities and unknown ingredients
Kamagra is often manufactured in countries with less stringent regulations than the UK. This means there’s a higher chance that Kamagra could be contaminated with substances that are harmful to your health. Additionally, you cannot be sure that the amount of sildenafil matches what the manufacturer claims. You could unintentionally take a dangerous dose of the medication without knowing it.
Lack of specialist medical advice
Erectile dysfunction can be a symptom of underlying health conditions, some of which are very serious. Without consulting your doctor, you might miss a condition that could be treated with the right care. There are also cases where ED medication alone will not resolve the issue, and the underlying condition needs to be addressed first.
When you visit a doctor for ED treatment, they will assess your health and ensure the medication is safe for your specific situation, considering any other medications or health conditions. With unlicensed medications like Kamagra, you do not receive this crucial medical guidance, putting your health at risk.
Safe Kamagra alternatives
For your health and safety, always consult a doctor before using any ED treatments. Choose licensed, regulated medications prescribed by a professional, and avoid risky, unregulated products like Kamagra. This ensures you get the right treatment tailored to your needs – without the risks.
