Kamagra and sildenafil are closely related terms, but they do not mean exactly the same thing. Sildenafil is an active pharmaceutical ingredient used to treat erectile dysfunction (ED), while Kamagra is a brand of products that contains sildenafil.
This distinction is particularly important in the UK because sildenafil is available in authorised medicines, while Kamagra is not an authorised medicinal product in the United Kingdom.
This guide explains the relationship between Kamagra and sildenafil, how Kamagra compares with other sildenafil medicines, and why the product name and active ingredient should not be treated as interchangeable terms.
What Is Sildenafil?
Sildenafil is a medicine mainly used for the treatment of erectile dysfunction. It belongs to a group of medicines called phosphodiesterase type 5 inhibitors, usually shortened to PDE5 inhibitors.
During sexual stimulation, sildenafil can help increase blood flow to the penis. It does not automatically produce an erection and does not increase sexual desire.
Sildenafil is the active ingredient used in Viagra as well as many generic sildenafil medicines.
Official information about sildenafil, its use and possible side effects is available from the NHS sildenafil guidance.
What Is Kamagra?
Kamagra is a brand associated with erectile dysfunction products containing sildenafil citrate.
Kamagra is available internationally in several formulations, most notably conventional tablets and Oral Jelly sachets.
The key distinction is simple:
- Sildenafil is the active pharmaceutical ingredient.
- Kamagra is a brand of products containing sildenafil.
Therefore, Kamagra contains sildenafil, but not every sildenafil medicine is Kamagra.
Does Kamagra Contain Sildenafil?
Yes. Kamagra products are associated with sildenafil citrate as their active ingredient.
For example, Kamagra tablets commonly carry a stated strength of 100mg sildenafil, while Kamagra Oral Jelly is also commonly supplied as a sildenafil-containing formulation.

Kamagra vs Sildenafil: What Is the Difference?
The main difference between Kamagra and sildenafil is that one describes a particular product brand while the other describes the medicine’s active ingredient.
This is similar to the distinction between a branded medicine and the pharmaceutical substance contained within it.
Two products may both contain sildenafil but differ in several important respects, including:
- Manufacturer
- UK marketing authorisation
- Available strengths
- Formulation
- Packaging
- Patient information
- Manufacturing and regulatory oversight
For this reason, the fact that two products contain sildenafil does not mean that their regulatory status is identical.
Kamagra 100mg Sildenafil
Kamagra tablets are commonly associated with a stated dose of 100mg sildenafil.
However, sildenafil is available in different strengths, and the highest strength is not automatically the most appropriate option for every person.
The appropriate dose can depend on health conditions, other medicines being taken, previous response to sildenafil and professional medical advice.
Taking more sildenafil than recommended can increase the likelihood of adverse effects.
Kamagra Oral Jelly and Sildenafil
Kamagra Oral Jelly also contains sildenafil but uses a different physical formulation from a conventional tablet.
Instead of being supplied as a solid tablet, the product is presented as a soft jelly in individual sachets.
The different formulation does not change the fact that sildenafil is the active ingredient, and the usual sildenafil safety considerations still apply.
See our Kamagra Oral Jelly UK guide for more detailed information about this formulation.
Is Sildenafil Authorised in the UK?
Yes. Sildenafil is an established medicine and is present in a number of medicines authorised for use in the United Kingdom.
Some sildenafil products are prescription medicines, while certain sildenafil products can also be supplied through UK pharmacies following an appropriate pharmacist assessment.
The regulatory status of sildenafil as an active ingredient should not, however, be confused with the regulatory status of every product containing sildenafil.
Is Kamagra Authorised in the UK?
Kamagra is not an authorised medicinal product in the United Kingdom.
This is one of the most important differences to understand when comparing Kamagra with sildenafil medicines that have UK marketing authorisation.
An unlicensed medicine does not have the same UK marketing authorisation as an authorised medicinal product.
The Medicines and Healthcare products Regulatory Agency (MHRA) is responsible for regulating medicines in the UK and provides guidance concerning unlicensed medicinal products.
More information is available from the MHRA guidance on unlicensed medicines.
Is Kamagra the Same as Viagra?
No. Kamagra and Viagra are different branded products, although both are associated with the same active ingredient: sildenafil.
Viagra is the original sildenafil brand. Generic medicines containing sildenafil are also widely available.
Products containing the same active ingredient can nevertheless differ in manufacturer, formulation, regulatory approval, packaging and quality-control arrangements.
It is therefore more accurate to say that Kamagra and Viagra may share the active ingredient sildenafil rather than saying they are the same medicine.
How Does Sildenafil Work?
Sildenafil is a PDE5 inhibitor. During sexual stimulation, chemical signals cause blood vessels supplying the penis to relax and allow increased blood flow.
Sildenafil supports this process by reducing the action of the PDE5 enzyme.
Sexual stimulation is still necessary for the medicine to have its intended erectile effect.
Sildenafil Side Effects
Sildenafil can cause side effects, although not everyone experiences them.
Commonly reported side effects can include:
- Headache
- Dizziness
- Indigestion or stomach discomfort
- Blocked or stuffy nose
- Nausea
- Temporary changes in vision
More serious reactions are less common but can require urgent medical attention.
Anyone experiencing worrying or persistent symptoms should seek appropriate medical advice.
Sildenafil and Nitrate Medicines
Sildenafil can interact with other medicines and is not suitable for everyone.
A particularly important interaction involves nitrate medicines used to treat chest pain or angina. Sildenafil should not normally be combined with nitrates because this can cause a dangerous reduction in blood pressure.
People taking other medicines or living with cardiovascular or other significant medical conditions should discuss sildenafil with a doctor or pharmacist.
Kamagra, Sildenafil and UK Medicine Information
