Kamagra (Sildenafil) 100 mg Oral Tablets: PDE5 Inhibitor for Erectile Dysfunction — Genuine Licensed Alternatives Available

Reviewed by the Lucas Clinic Medical Team | Updated May 2026

Kamagra is a brand name used by Ajanta Pharma (India) for a product marketed as sildenafil citrate — the same active ingredient as Viagra. Kamagra is sold in tablet and oral jelly forms in widely recognised packaging and at prices significantly below licensed sildenafil. Despite this, Kamagra is not licensed or approved for sale as a medicine in the United States, the United Kingdom, the European Union, Canada, or Australia. It has not undergone the regulatory review required to be sold legally as a pharmaceutical product in those jurisdictions. The active ingredient sildenafil is a PDE5 inhibitor that requires a valid prescription in all these territories — and obtaining sildenafil outside the regulated supply chain, under any brand name, carries serious risks.

This page exists to explain the regulatory facts about Kamagra and to help patients understand the correct pathway to accessing safe, licensed sildenafil for erectile dysfunction (ED).

What Is Kamagra?

Kamagra is manufactured by Ajanta Pharma, a legitimate Indian generic pharmaceutical company. Ajanta holds Drug Controller General of India (DCGI) approval to manufacture and sell Kamagra within India. However, this approval does not extend to other countries. For a medicine to be sold legally in the US, UK, or EU, it must be licensed by the FDA, MHRA, or EMA respectively — a process involving rigorous review of manufacturing quality, clinical data, and labelling. Kamagra has not applied for or obtained such approvals.

In the UK in particular, the MHRA has consistently warned that Kamagra purchased online is classified as a counterfeit or unlicensed medicine, because the product circulating in the UK supply chain does not come via Ajanta — it comes primarily from unverified third-party websites and grey-market resellers. These products may contain the correct dose of sildenafil, a different dose, no active ingredient, or entirely different and dangerous compounds. The MHRA and NHS actively advise against purchasing Kamagra online. Similar warnings are issued by the FDA, Health Canada, and the TGA.

Why Buying Unlicensed Sildenafil Is Dangerous

Sildenafil is cardiovascularly active. The main systemic effect — smooth muscle relaxation via PDE5 inhibition — extends to vascular smooth muscle throughout the body, not just in penile tissue. For the majority of healthy men, this effect is clinically manageable with appropriate screening. But for men taking nitrates (used for angina — GTN spray, isosorbide mononitrate, isosorbide dinitrate), the combination causes severe, potentially fatal hypotension. This is the key reason sildenafil requires a prescription: to ensure nitrate use is screened out before dispensing. Purchasing unlicensed sildenafil online bypasses this critical safety check entirely. Men who take nitrates — often without knowing their heart disease is serious enough to warrant them — are at life-threatening risk.

What Sildenafil Products Are Licensed?

Licensed sildenafil products available in the US include Viagra (Pfizer; 25/50/100 mg tablets — now off-patent) and numerous generic sildenafil products from FDA-approved manufacturers in doses of 20/25/50/100 mg. Generic sildenafil is widely available via legitimate online telehealth platforms and in-person pharmacies at prices that now range approximately $15–$30 for 4 tablets of 50 mg or 100 mg. The days of $15-per-pill branded Viagra are over — licensed generic sildenafil is genuinely affordable and accessible through legitimate channels. In the UK, generic sildenafil 50 mg (4 tablets) is available OTC as Viagra Connect from pharmacies after a consultation, for around £15–£20.

Price of Kamagra vs. Licensed Sildenafil

Kamagra oral jelly and tablets are frequently marketed online for £10–£20 per ten-unit pack, or similar pricing in USD. Licensed generic sildenafil in the US is now available via telehealth platforms for comparable or minimally higher costs — with the added value of a proper medical consultation, a valid prescription, and product from an FDA-inspected manufacturer. The cost differential that historically drove Kamagra purchases has largely evaporated with patent expiry of sildenafil. There is no longer a meaningful price advantage to purchasing unlicensed product, and the safety risks remain substantial.

Frequently Asked Questions

Is Kamagra legal to buy in the UK?

No. Kamagra is not licensed for sale in the UK and purchasing it (whether in person or online) is illegal under the Medicines Act 1968. The MHRA classifies it as an unlicensed medicine. UK pharmacies and online retailers with a valid MHRA registration do not stock or sell Kamagra. Products marketed as Kamagra in the UK come from unregulated supply chains and carry unknown safety profiles. Men in the UK seeking ED treatment should approach their GP or use a registered online pharmacy (identifiable by the EU common logo and MHRA registration) to obtain licensed sildenafil.

Does Kamagra work the same as Viagra?

If a Kamagra product contains the correct amount of genuine sildenafil — which cannot be verified without laboratory analysis — it would theoretically work via the same mechanism as Viagra. However, the key unknowns are: actual active ingredient identity, dose accuracy, manufacturing quality, excipient safety, and absence of harmful adulterants. Regulatory approval ensures these are verified by independent bodies. Unlicensed product provides none of those guarantees. In practice, FDA/MHRA analyses of unlicensed sildenafil products have found a range of potency from zero active ingredient to doses double or triple the labelled amount — both scenarios posing harm risk.

What is the safe alternative to Kamagra?

The safe alternative is a prescription for licensed generic sildenafil obtained through a qualified prescriber — a GP, urologist, or registered online telehealth service (e.g., Hims, Roman, Keeps in the US; ZAVA, Treated, Superdrug Online Doctor in the UK). These services can complete a medical history review, screen for contraindications (nitrates, alpha-blockers, cardiovascular disease), and issue a valid prescription that is dispensed by a regulated pharmacy. The process typically takes under 30 minutes and can often be completed before the end of the same day.
