Outline
Sildenafil citrate is the active ingredient. Formulation: an effervescent tablet designed to dissolve in a glass of water prior to ingestion. The product commonly marketed as Kamagra Effervescent is available as a 100 mg dose per tablet.
Application for which it is intended: treatment of erectile dysfunction in adult men. This formulation supports the physiological erection process in response to sexual stimulation; it is not intended to increase sexual desire.
Regulatory note: Kamagra is a trade name used in some international markets for sildenafil-containing products. In the United States, sildenafil products that are approved by FDA are available from licensed manufacturers, but Kamagra-branded items are not FDA-approved. View the section of the document that covers legal matters for more details: Notes on U.S. law.
How it operates step by step and also the outward signs
Sildenafil's action is to inhibit phosphodiesterase type 5 (PDE5). When PDE5 activity is reduced during sexual arousal, cyclic GMP levels in penile tissue rise, which supports increased blood flow into the corpus cavernosum and helps produce and maintain an erection.
Important: sexual stimulation is required for sildenafil to produce an erection. The medication will not induce sexual desire on its own.
How to employ
Typical procedure for taking an effervescent sildenafil tablet:
- Drop one tablet into a glass of water, wait until it dissolves completely, stir if needed, and drink the entire solution.
- Do not exceed one dose in any 24 hour period unless specifically instructed by a healthcare professional.
- Time to onset varies; many people notice effects between 30 minutes and 2 hours after taking the tablet.
- If you skip a planned dose, take it only when needed and if you are not already over the 24 hour limit. Do not double dose to compensate for a missed one.
- A large, high fat meal may delay absorption and postpone onset of action. Limit use of alcohol around dosing because it can decrease effectiveness and increase follow-on effects such as lightheadedness.
Dosage change and adjustments
For the effervescent presentation the usual maximum is one 100 mg tablet per day. Some users achieve good results with lower amounts. Because effervescent tablets are not always convenient to split precisely, clinicians may prefer an additional choice sildenafil forms if careful dose adjustment is needed.
Adjustments may be required for older adults or for people with significant liver or kidney impairment. Discuss individual dosing with your prescriber before therapy commences.
Storage and care management
Keep the product at normal room temperature, approximately 15 to 30 degrees C (59 to 86 degrees F). Protect from excessive moisture, heat, and direct sunlight. Store all medications out of the reach of children and pets.
Product safety alert notices and health conditions that forbid use
No exception contraindication list
- Concurrent use of nitrates or nitroprusside in any form because of risk of profound hypotension.
- Use of another PDE5 inhibitor (for example tadalafil, vardenafil, avanafil) or any product that already contains sildenafil.
- Known hypersensitivity to sildenafil or to any component of the effervescent tablet.
- If a clinician has advised against sexual activity due to significant cardiovascular risk.
Harm prevention measures to discuss under the supervision of your clinician.
- Recent myocardial infarction, stroke, unstable angina, serious arrhythmias, or poorly controlled blood pressure.
- Moderate to severe liver disease or severe renal impairment.
- Blood disorders or penile conditions that raise the risk of prolonged erection, such as sickle cell disease, leukemia, multiple myeloma, or Peyronie disease.
- A history of optic neuropathy or sudden changes in vision or hearing.
- All prescription medicines, over-the-counter drugs, herbal products, and dietary supplements you are taking.
Key safety alerts
- Avoid driving or operating heavy machinery until you know how sildenafil affects you; it can cause dizziness or blurred vision.
- Seek emergency care for chest pain, severe shortness of breath, sudden weakness or numbness, slurred speech, or other symptoms of heart attack or stroke.
- If an erection persists longer than four hours or is painful, obtain immediate medical attention to reduce the risk of permanent injury.
- Although rare, sudden vision or hearing loss has been reported; stop the medication and contact your clinician immediately if these occur.
- This medication does not protect against sexually transmitted infections or prevent pregnancy. Use barrier protection and contraception as appropriate.
Foods that alter drug performance
Tell your prescriber or pharmacist about all medications, supplements, and herbal products you use. Interactions among users can lower effectiveness, increase adverse sequelae, or produce dangerous changes in blood pressure.
- Nitrates and nitric oxide donors: combining these with sildenafil can cause a severe drop in blood pressure. Do not take together.
- Alpha blockers and many blood pressure medicines: may have additive blood pressure lowering effects; timing and dose adjustments may be necessary.
- Strong CYP3A4 inhibitors (for example ritonavir, ketoconazole, itraconazole): can increase sildenafil concentrations besides the risk of adverse health effects.
- CYP3A4 inducers such as rifampin: can reduce sildenafil levels and decrease clinical effect.
- Cimetidine the H2 receptor antagonist and some macrolide antibiotics may raise sildenafil exposure.
- Opioids, benzodiazepines, and other central nervous system depressants can increase drowsiness and dizziness when taken together.
- Grapefruit and grapefruit juice may increase sildenafil concentrations; discuss dietary guidance with your healthcare provider.
This is a partial list. Confirm potential tracking the exchange between peoples helps measure engagement. with your clinician or pharmacist before starting or stopping any medicine.
