Key takeaways
Kamagra is sildenafil made by Ajanta Pharma in India, sold as tablets and oral jelly. It is not a different, stronger or gentler medicine than prescription sildenafil.
It is not registered with the Thai FDA, so selling it in Thailand is illegal. Every vendor, street or online, operates outside any quality control.
Laboratory testing of grey-market sildenafil repeatedly finds wrong doses, contaminants and outright fakes. You cannot tell genuine from counterfeit by looking.
If you develop chest pain or faintness after taking it, especially alongside nitrate medicines or poppers, call 1669, Thailand's emergency line.
The same active ingredient is available legally: after a short health review, a doctor can prescribe Thai-FDA-registered sildenafil or tadalafil.
01
What Kamagra is & why it exists
Kamagra is a brand of sildenafil citrate, the same active ingredient as Viagra, made by Ajanta Pharma, a large Indian manufacturer. It is sold as 100 mg tablets and as flavoured single-dose oral jelly sachets. The molecule itself is a legitimate, well-studied medicine. The product, as it reaches Thailand, is not.
Kamagra exists for markets it is not licensed in. Ajanta has not registered it with the Thai FDA, and regulators such as the UK MHRA list it among the unlicensed erectile dysfunction products they warn against.⁴ Every Kamagra sale here happens outside the regulated supply chain. That gap is the business model: no registration costs, no pharmacovigilance, no pharmacist asking about your heart medication, and prices that undercut licensed products.
The consequence is that 'Kamagra' in Thailand is not one product. Some of it is genuine Ajanta stock diverted through grey channels and shipped without storage control. A large share is counterfeit, made by whoever prints the sachets. From the outside, the packaging is often indistinguishable.
None of this is an argument against treating erectile dysfunction. It is an argument for getting the same medicine through a channel where someone is accountable for what is inside it.
What is in it
Sildenafil citrate, nominally 100 mg per tablet or sachet. The label is only as reliable as the seller, and testing of grey-market sildenafil regularly contradicts it.¹
How it differs from pharmacy sildenafil
The molecule is identical. What is missing is oversight: no Thai FDA registration, no batch traceability, no pharmacist, no doctor reviewing the medicines you already take.
Why the jelly format
Single-dose sachets are easy to swallow and ship discreetly. Claims of meaningfully faster onset than tablets are not supported by good comparative trials.
Why it is cheap
No registration, no quality audits, no regulated distribution, and often no genuine manufacturer. The saving comes out of exactly the safeguards you would want.
02
Kamagra's legal status in Thailand
Not registered with the Thai FDA
Kamagra has no marketing authorisation in Thailand. Under the Drug Act B.E. 2510, selling an unregistered drug is a criminal offence, so there is no legal Kamagra vendor here, in a shop or online.⁵
Customs & bringing it in
Travellers may generally carry up to 30 days of personal medication with a prescription. Kamagra rarely qualifies: it is unregistered here and usually bought without a prescription, so it can be seized, and quantities that suggest resale invite prosecution.
What pharmacies can legally sell
Thai-FDA-registered sildenafil, including the original brand and the local generic Sidegra made by the Government Pharmaceutical Organization. All are special-control drugs (ยาควบคุมพิเศษ): a pharmacy needs a doctor's prescription to dispense them.
Thai FDA position. The regulator warns that unregistered imported medicines carry unverifiable contents and no consumer protection, and that sellers face penalties under the Drug Act. A buyer harmed by an illegal product has, in practice, nobody to hold to account.⁵
03
What testing finds in grey-market sildenafil
Erectile dysfunction medicines are among the most counterfeited drugs in the world, and the numbers are not subtle. When Pfizer test-purchased 'Viagra' from 22 websites and analysed the samples, 77% were counterfeit, and the counterfeits contained 30% to 50% of the sildenafil stated on the label.¹
Published analyses of seized counterfeit PDE5 inhibitors have found commercial-grade paint, printer ink, talcum powder and undeclared drugs such as amphetamine alongside, or instead of, the active ingredient.² The WHO estimates roughly 1 in 10 medical products circulating in low- and middle-income countries is substandard or falsified.³
Kamagra sits squarely in this pool. Even a genuine Ajanta sachet reaching Bangkok has travelled outside any audited chain, with no storage control in tropical heat, no batch recall route, and no way for you to distinguish it from the fakes that share its packaging. The honest summary: you do not know the dose, and you cannot find out.

What can go wrong & who is most at risk
Unknown dose
Analyses find both under-dosed and over-dosed samples. A sachet labelled 100 mg that delivers much more raises the risk of severe headache, flushing, a drop in blood pressure and priapism, an erection lasting more than 4 hours that can permanently damage the penis without urgent treatment.
Nitrate interactions
Sildenafil combined with nitrates (angina sprays and tablets, or recreational poppers) can drop blood pressure to dangerous levels.⁶ If you develop chest pain or faintness after taking any sildenafil product, call 1669, Thailand's emergency line.
No cardiac screening
Erectile dysfunction is often an early sign of cardiovascular disease, sometimes years ahead of other symptoms.⁷ Buying from a street seller skips the one check that matters most: whether your heart is behind the problem, and whether it can safely handle the medicine.
No legal recourse
If a licensed product harms you, there is a manufacturer, a batch number and a regulator. If Kamagra harms you, there is a seller who has already broken the law. Tell doctors honestly what you took; they are there to treat you, not to judge you.
05
The legal route to the same medicine
Prescription · same molecule
Sildenafil, done properly
A doctor can prescribe Thai-FDA-registered sildenafil dispensed by a licensed pharmacy, with a verified dose of the exact ingredient Kamagra claims to contain. Our sildenafil guide covers doses, timing and side effects in detail.
Prescription · longer window
Tadalafil
An alternative PDE5 inhibitor that works for up to 36 hours, or can be taken as a low daily dose. Many men prefer it because timing matters less. A doctor helps you choose between the two.
The step that matters
A proper health review
Fifteen minutes with a doctor covers blood pressure, heart risk, the medicines you already take, especially nitrates, and whether the ED itself points to something worth testing, such as diabetes or low testosterone.⁷

How getting checked works at Menscape
/)
Book a private 15-minute consultation.
Start on WhatsApp or LINE
Message our team in English or Thai and describe what is going on in your own words. It is private, and no question about past Kamagra use will raise an eyebrow.
See the doctor
A 15-minute consultation at our clinic in Phrom Phong, Bangkok. The doctor reviews your health history, current medicines and heart risk factors before anything is prescribed.
Prescription, if appropriate
If a PDE5 inhibitor is suitable and safe for you, you leave with a prescription for a Thai-FDA-registered product, dispensed by a licensed pharmacy.
Follow-up
Dose and choice of medicine are adjusted based on how the first prescription works for you. If the doctor suspects an underlying cause, they will suggest the right tests.
The doctor decides. A consultation is not a purchase, and a prescription is not automatic. If a PDE5 inhibitor is not safe for you, the doctor will say so and discuss what is.

Frequently asked questions
Is Kamagra legal in Thailand?
No. It is not registered with the Thai FDA, so selling it here is an offence under the Drug Act B.E. 2510. There is no licensed Kamagra vendor in Thailand; every seller, street or online, is operating illegally.
Can I bring Kamagra through Thai customs?
Travellers may generally carry a personal supply of medicines, up to about 30 days, with a prescription. Kamagra rarely qualifies: it is unregistered in Thailand and usually bought without a prescription, so it can be seized. Quantities that suggest resale risk prosecution.
Is Kamagra the same as Viagra?
Genuine Kamagra contains the same active ingredient, sildenafil. The difference is oversight: Viagra and Thai-registered generics such as Sidegra move through an audited chain with verified doses. Kamagra in Thailand does not, and a large share of what is sold under the name is counterfeit.
Why is Kamagra banned in Thailand?
Strictly, it is not banned; it was never registered. Ajanta Pharma has not sought a Thai marketing authorisation, and under Thai law any unregistered drug is illegal to sell. The same rule would apply to any other unlicensed product.
I already took Kamagra. What should I do?
A single dose in an otherwise healthy man is usually uneventful. Stop taking it, never combine it with nitrates or poppers, and treat chest pain, fainting or an erection lasting over 4 hours as an emergency: call 1669. Then have a doctor review your heart risk and prescribe a legal alternative if treatment makes sense.
Is the jelly really faster than tablets?
Marginally at best. Sildenafil tablets typically work within 30–60 minutes, and claims that the jelly acts meaningfully faster are not backed by good comparative trials. The format exists mainly for marketing and discreet shipping.
What if mine is the genuine Ajanta product?
You cannot verify that, which is the core problem. Even a genuine sachet reaching Thailand has left the regulated chain: no storage control in tropical transit, no batch recall, no pharmacist. And you have still skipped the health check that determines whether sildenafil is safe for you.
How do I get sildenafil legally in Bangkok?
Through a doctor. Sildenafil is a special-control drug in Thailand (ยาควบคุมพิเศษ), so a prescription is required. After a 15-minute consultation covering your heart health and current medicines, a doctor can prescribe a Thai-FDA-registered product, dispensed by a licensed pharmacy.
