Medicine overview

Kamagra Fizz 100 mg is an effervescent sildenafil medicine used for erectile dysfunction in adult men. Regulatory records identify Kamagra 100 mg Effervescent as an oral effervescent tablet manufactured by Ajanta Pharma Limited and containing sildenafil citrate 100 mg. Sildenafil belongs to the phosphodiesterase type 5 (PDE5) inhibitor class. It supports the natural erectile response by increasing blood flow to the penis during sexual stimulation; it does not produce an erection without sexual stimulation.

What it is used for

Kamagra Fizz 100 mg is used for the treatment of erectile dysfunction, meaning difficulty getting or maintaining an erection sufficient for sexual activity. Sildenafil improves erectile response when sexual stimulation is present. This product should not be treated as interchangeable with sildenafil products intended for pulmonary arterial hypertension, or with other Kamagra dosage forms such as oral jelly, chewable tablets, or conventional tablets.

How it works

Sildenafil blocks phosphodiesterase type 5 (PDE5), an enzyme that normally breaks down cyclic guanosine monophosphate (cGMP). During sexual stimulation, nitric oxide increases cGMP in erectile tissue, causing smooth muscle to relax and allowing more blood to enter the penis. By slowing cGMP breakdown, sildenafil strengthens this natural response. Sexual stimulation is still required because sildenafil does not directly cause an erection or increase sexual desire.

How it is taken

Kamagra Fizz is an oral effervescent tablet and should be dissolved in water before administration rather than swallowed as a conventional tablet. General sildenafil prescribing information states that sildenafil for erectile dysfunction is taken before anticipated sexual activity and should not be used more than once daily. The exact product-specific volume of water and administration timing for Kamagra Fizz could not be verified from an authoritative current package insert, so those details should follow the supplied product instructions or a healthcare professional's directions.

Important warnings

Do not use sildenafil with nitrates or nitric oxide donors, including nitroglycerin, isosorbide medicines, or recreational nitrites ("poppers"), because the combination can cause a dangerous fall in blood pressure. It is also contraindicated with guanylate cyclase stimulators such as riociguat and in people with hypersensitivity to sildenafil. Medical assessment is important when cardiovascular disease makes sexual activity unsafe. Sildenafil can further lower blood pressure with alpha-blockers and antihypertensive medicines, while strong CYP3A4 inhibitors such as ritonavir, ketoconazole, itraconazole, and some macrolide antibiotics can substantially increase sildenafil exposure. Do not combine it with other PDE5 inhibitors or erectile-dysfunction treatments unless specifically directed by a healthcare professional. Seek urgent medical attention for an erection lasting more than 4 hours, sudden loss of vision, sudden reduction or loss of hearing, fainting, or chest pain during sexual activity.

Side effects and monitoring

Common sildenafil side effects include headache, flushing, indigestion, nasal congestion, nausea, dizziness, back or muscle pain, and temporary visual disturbances such as blurred vision or altered color perception. Serious but less common problems include prolonged or painful erection (priapism), sudden vision loss associated with possible non-arteritic anterior ischemic optic neuropathy (NAION), sudden hearing decrease or loss, severe hypotension, and hypersensitivity reactions. Stop sexual activity and obtain medical attention if chest pain, severe dizziness, or nausea develops. Urgent assessment is required for an erection lasting more than 4 hours or sudden vision or hearing loss.

Pregnancy

Kamagra Fizz for erectile dysfunction is not indicated for use in females. Human pregnancy data for sildenafil are insufficient to establish drug-associated developmental risk for this indication.

Breastfeeding

Kamagra Fizz for erectile dysfunction is not indicated for use in females. Sildenafil and its active metabolite have been detected in human milk, but available information is insufficient to establish effects on a breastfed child or milk production.

Food, drink and interactions

Avoid excessive alcohol when using sildenafil. Drinking a large amount of alcohol can make it more difficult to achieve an erection and may add to dizziness or blood-pressure-lowering effects.

Food and drink

Sildenafil can generally be taken with or without food, but a high-fat meal can delay absorption and may make it take longer to work. Grapefruit or grapefruit juice may increase sildenafil exposure and the likelihood of side effects, so avoiding grapefruit is prudent when using sildenafil.

Frequently asked questions

Does sildenafil need sexual stimulation to work?

Yes. Sildenafil supports the natural erectile response during sexual stimulation; it does not automatically cause an erection or increase sexual desire.

Does eating before sildenafil make it less effective?

Food does not prevent sildenafil from being used, but a high-fat meal can delay its absorption and make the effect take longer to begin.

Why do some people get headaches, flushing, or a blocked nose with sildenafil?

These are recognized common effects of sildenafil and are related partly to its effects on blood vessels. Seek medical advice if side effects are troublesome, severe, or persistent.

Can I take Kamagra Fizz with Viagra, tadalafil, or another ED medicine?

Do not combine sildenafil with other PDE5 inhibitors or erectile-dysfunction treatments unless a healthcare professional specifically directs you to do so. Combining them can increase adverse effects, including low blood pressure.

What should I do if an erection lasts more than 4 hours?

Get emergency medical treatment immediately. A prolonged erection, called priapism, can permanently damage penile tissue if it is not treated promptly.

Can I take Kamagra Fizz if I use nitroglycerin for chest pain?

No. Sildenafil must not be combined with nitrates such as nitroglycerin because blood pressure can fall to a dangerous level.

Does Kamagra Fizz work differently because it is effervescent?

It is an effervescent sildenafil formulation that is dissolved before oral administration. Reliable product-specific evidence showing a clinically meaningful advantage in onset or effectiveness over conventional sildenafil tablets was not verified.

Is Kamagra Fizz 100 mg a prescription medicine?

Yes. The regulatory product record used to verify Kamagra 100 mg Effervescent classifies it as a prescription-only medicine. Prescription classification can differ between countries.
