Kamagra 100mg is the tablet form of generic sildenafil at 100mg, the maximum single dose in the EU product information for sildenafil. This guide covers what the dose does, how and when to take it, how the tablet compares to the oral jelly, and the rules that keep it safe.

What Kamagra 100mg is

Each tablet contains sildenafil citrate 100mg — the identical active ingredient and dose as Viagra 100mg, made by Ajanta Pharma under GMP conditions. Sildenafil inhibits the PDE5 enzyme so that, with arousal, blood flows into the penis and stays there. The EU product information for sildenafil gives 50mg as the usual dose and 100mg as the maximum, so a 100mg tablet is the top of that range; which strength suits you is a doctor's decision.

When and how to take it

Take it about an hour before intimacy, ideally on a lighter stomach — heavy or fatty meals delay onset. It works for around four hours, and only with arousal. The tablet is swallowed with water; there is no EU data showing the oral jelly is faster (in the EU product information, sildenafil's orodispersible tablet had the same timing as the film-coated tablet). One dose per 24 hours maximum.

Tablet vs oral jelly

Same medicine, same dose — there is no EU data showing the jelly is faster (the EU timing for sildenafil tablets, including the orodispersible tablet, is about 1 hour before sex), and the jelly needs no water, while the tablet is simpler to store and carry. Choose on preference; the full comparison is in which Kamagra is right for you. Both must pass the same genuine-product checks.

Safety and interactions

Never combine sildenafil with nitrate medicines or poppers — the one absolute rule. Take medical advice if you have heart, liver or kidney conditions or take blood-pressure medicines, and treat new ED as a reason to see a doctor, since it can signal vascular disease. Common side effects (headache, flushing, congestion) are usually mild and dose-related — detail in the complete Kamagra guide.

Getting genuine Kamagra 100mg

Insist on sealed Ajanta blisters with a batch number and expiry, an identifiable seller and a patient leaflet — the five checks. Larger packs cut the per-tablet price sharply. Buying detail is on the Kamagra 100mg page (or the Kamagra Oral Jelly 100mg page for the gel format); the regulatory picture is in is Kamagra legal.

Take it about one hour before sex, as the EU product information for sildenafil advises; a clinical study showed it could still work with arousal 4–5 hours after the dose.

  • How to Take Kamagra Oral Jelly: Timing, Food & Dose

    Summary: Open one Kamagra Oral Jelly sachet (100mg sildenafil) and swallow the gel directly, ahead of sex; a heavy meal beforehand delays absorption. Never take more than one sachet in 24 hours, never with nitrates or poppers, and remember it only works with arousal.

    Summary: Kamagra chewable tablets contain sildenafil, the same medicine as standard Kamagra, in a flavoured tablet you chew instead of swallowing with water.

It still needs arousal, is taken before planned sex rather than daily, and must never be combined with nitrates.

Never combine it with nitrates.
