Kamagra Fizzy Tabs is the effervescent tablet formulation of sildenafil citrate 100mg in the Ajanta Pharma Kamagra range. Unlike all other Kamagra formats — which are either swallowed or chewed — Kamagra Fizzy is dropped into a glass of water, where it dissolves within one to two minutes to produce a flavoured sparkling solution that is then consumed as a drink. The effervescent format delivers sildenafil already in aqueous solution, bypassing the gastric disintegration step required by solid tablets and producing a faster onset of 20–30 minutes. It is the only Kamagra format that requires water by design, and the only one consumed as a liquid rather than a solid.
Kamagra Fizzy in the Ajanta Kamagra Range
Understanding where Kamagra Fizzy sits relative to other Kamagra formats helps identify the context in which it is most appropriately used:
| Format | Administration | Onset | Water | Key characteristic |
|---|---|---|---|---|
| Kamagra Fizzy Tabs (this product) | Dissolve in water; drink the solution | 20–30 min | Required (dissolving) | Liquid consumption; sildenafil in solution; flavoured drink format |
| Kamagra Gold | Swallow whole with water | 45–60 min | Required | Standard film-coated tablet; most stable format |
| Kamagra 100mg | Swallow whole with water | 45–60 min | Required | Standard tablet; same pharmacology as Gold |
| Kamagra Polo | Chew until dissolved; swallow | 20–30 min | Not required | Polo-shaped; pineapple-mint; most discreet |
| Kamagra Soft | Chew until dissolved; swallow | 20–30 min | Not required | Oblong chewable; fruit flavours |
| Kamagra Oral Jelly | Squeeze sachet directly into mouth; swallow | 15–25 min | Not required | Fastest onset; gel consistency; absorbed through oral mucosa |
Kamagra Fizzy is well suited to men who prefer to take medication as a drink rather than swallowing or chewing a solid tablet — for example, those who have difficulty with tablets, or who find the drink format more comfortable and natural. The flavoured solution also provides a more gradual, pleasant administration experience compared to swallowing a tablet whole.
How the Effervescent Format Produces Faster Onset
The onset advantage of Kamagra Fizzy over a standard film-coated sildenafil tablet is a direct consequence of the pharmaceutical form. When an effervescent tablet is dropped into water, a chemical reaction between the tablet's citric acid and sodium bicarbonate excipients produces carbon dioxide (CO2), causing the characteristic fizzing. Simultaneously, the tablet matrix rapidly disintegrates and the sildenafil citrate dissolves into the water.
When you drink the resulting solution, sildenafil is already in dissolved aqueous form — not as a solid particle that must first disintegrate and dissolve in the stomach. This means gastric absorption can begin immediately on contact with the gastric mucosa, without the disintegration and dissolution lag phases that slow a standard film-coated tablet. The result is a faster rise to peak plasma concentration (Tmax) and a clinical onset of approximately 20–30 minutes, compared to 45–60 minutes for the standard tablet.
The mechanism differs from the chewable formats (Kamagra Polo, Kamagra Soft): chewables gain speed through partial buccal mucosal absorption during chewing. Fizzy tabs gain speed through pre-dissolution in water before ingestion. The practical outcome — onset of 20–30 minutes — is similar for both approaches.
Dosage and Administration
- Drop one tablet into a glass of water (approximately 200–250 mL / one standard glass)
- Allow the tablet to fully dissolve — this takes approximately 1–2 minutes; do not drink until dissolution is complete
- Drink the entire solution; do not leave part of the glass undrank, as the sildenafil is distributed throughout the liquid
- Take 20–30 minutes before anticipated sexual activity; individual onset may range from 15 to 60 minutes depending on metabolism, food intake and other factors
- Do not exceed one 100mg tablet in any 24-hour period
- Take on an empty stomach or after a light, low-fat meal only — a high-fat meal reduces sildenafil peak concentration by approximately 29% and delays onset by up to 60 minutes
- Limit alcohol to no more than 2 standard Australian drinks — greater amounts increase hypotension risk and independently impair erectile function
- Do not dissolve the tablet in alcoholic beverages, carbonated drinks or acidic juices — use plain water at room temperature for consistent dissolution and absorption
- Men aged 65 and over, those with hepatic or renal impairment, or those on CYP3A4 inhibitors should seek medical advice before use; a lower starting dose may be more appropriate
Storage — Moisture Sensitivity
- Keep tablets in their original sealed tube at all times until immediately before use
- Store in a cool, dry place below 30°C — away from bathrooms, kitchens and humid environments
- Do not store loose tablets in pill organisers, plastic bags or unsealed containers
- Replace the tube cap immediately after removing a tablet
- Discard any tablet that has partially dissolved, crumbled or shows signs of effervescence inside the tube
Critical Safety Information — Nitrates
Also absolutely contraindicated with: Riociguat (Adempas). Alpha-blockers (tamsulosin, doxazosin, alfuzosin) used for BPH or hypertension may cause symptomatic hypotension when combined with sildenafil — use with extreme caution; a starting dose of sildenafil 25mg is recommended if combination cannot be avoided.
Reminder: the nitrate safety window for sildenafil is 24 hours. For tadalafil (Cialis, Cialis Super Active), the required gap is 48 hours due to tadalafil's much longer half-life of approximately 17.5 hours. If you take any cardiac or blood pressure medication, consult your GP or cardiologist before using any sildenafil product.
Side Effects
Common side effects (1 in 100 or more)
- Headache — most common; dose-related and usually mild
- Flushing — warmth and redness of the face, neck or chest
- Nasal congestion or rhinitis
- Dyspepsia — indigestion or heartburn
- Dizziness
- Visual disturbances — mild blue tinge to vision (cyanopsia), increased sensitivity to light or brief blurring. Caused by PDE6 inhibition in retinal photoreceptors; specific to sildenafil; brief and resolves without treatment as plasma levels fall
Serious — seek immediate medical attention
- Priapism — a painful erection that lasts more than 4 hours. This is a medical emergency. Permanent erectile dysfunction can result if not treated promptly. Go immediately to an emergency department or call 000
- Sudden loss or significant decrease in vision — possibly associated with non-arteritic anterior ischaemic optic neuropathy (NAION)
- Sudden decrease or loss of hearing, with or without tinnitus or dizziness
- Severe chest pain, palpitations or collapse — do not use nitrates to treat; call 000 immediately
The visual side effects noted above are specific to sildenafil due to its inhibition of PDE6 in the retina, and are not seen with tadalafil or vardenafil, which have greater PDE5 selectivity. Kamagra Fizzy does not cause back pain or myalgia — that side effect is unique to tadalafil (PDE11 inhibition).

Frequently Asked Questions
How exactly do I take Kamagra Fizzy Tabs?
Drop one tablet into a standard glass of plain water (approximately 200–250 mL). Do not use juice, fizzy drinks or alcohol. The tablet will effervesce and dissolve within 1–2 minutes. Stir gently if dissolution is slow. Once fully dissolved, drink the entire glass. The sildenafil is distributed throughout the liquid, so drinking only part of it will reduce the dose you receive. Take 20–30 minutes before anticipated sexual activity.
Why does Kamagra Fizzy require water when Polo and Soft do not?
The effervescent format works by dissolving in water — this is the mechanism by which the tablet breaks down and the sildenafil enters solution. The chewable formats (Polo, Soft) dissolve through mechanical fragmentation during chewing and buccal absorption, which does not require water. The trade-off is that Fizzy must be prepared in advance with a glass of water, whereas chewable formats can be taken anywhere without preparation.
Does the effervescent fizzing affect how the sildenafil works?
No. The CO2 produced by the effervescent reaction is inert and escapes as gas before or after you drink the solution. It has no pharmacological effect on sildenafil absorption or efficacy. The mechanism of onset advantage is the pre-dissolution of sildenafil in water before ingestion, not the fizzing itself.
Why is the packaging a tube rather than a blister strip?
Effervescent tablets are highly sensitive to atmospheric moisture. Even brief exposure to humidity can trigger premature partial effervescence, degrading the tablet and reducing the available dose. The moisture-proof tube format, with a sealed cap and a desiccant, provides significantly better protection against humidity than a standard foil blister. Always replace the tube cap immediately after removing a tablet, and store in a cool dry place below 30 degrees Celsius.
Is there a difference in effectiveness between Kamagra Fizzy and Kamagra Oral Jelly?
Both contain sildenafil 100mg and have similar onset ranges, but the mechanisms differ slightly. Kamagra Oral Jelly is absorbed partly through the oral mucosa directly from the mouth, which can produce an onset as fast as 15–25 minutes. Kamagra Fizzy is absorbed in the stomach after the solution is swallowed, giving an onset of 20–30 minutes. In practice, the difference for most men is small. Both are faster than standard tablets. Oral Jelly requires no preparation; Fizzy requires a glass of water but some men find the drink format more comfortable to take. Clinical efficacy once absorbed is identical — same active ingredient, same dose.
