Viagra 50mg Tablet 4s

Viagra 50mg Tablet is a well-recognised prescription medicine belonging to the phosphodiesterase type 5 (PDE5) inhibitor drug class, with sildenafil citrate as its active pharmaceutical ingredient — manufactured by Pfizer and registered with the National Pharmaceutical Regulatory Authority (NPRA) of Malaysia as a prescription-only medicine (POM). Like all medicines, Viagra 50mg can cause side effects, and the most commonly reported ones include headaches, facial flushing (redness and warmth in the face), dizziness, and nasal congestion. It is important that you only take this medication under the guidance of a registered doctor, as it has significant interactions with certain heart medications (particularly nitrates) that can be life-threatening. If you have been prescribed Viagra 50mg, please ensure you follow your doctor's instructions carefully, declare all other medications you are taking, and only purchase from a licensed pharmacy or verified online pharmacy to guarantee you receive a genuine, NPRA-registered product.

How to Take Viagra 50mg Tablet

Viagra 50mg Tablet is taken orally — swallow the tablet whole with a glass of water, with or without food, approximately 30 to 60 minutes before it is needed, as directed by your doctor. Avoid taking it with a high-fat meal, as this can slow down the time it takes for the medicine to start working, and never take more than one dose in a 24-hour period. Always follow your prescribing doctor's specific instructions, as individual dosing guidance may vary based on your health status and other medications you are taking.

Dosage of Viagra 50mg Tablet

The recommended starting dose of Viagra for most adult men is 50mg, taken as needed approximately one hour before the relevant activity, with doses adjustable to 25mg or up to a maximum of 100mg depending on individual response and tolerability — as determined by your doctor. This medicine should not be taken more than once within any 24-hour period, and dose adjustments may be necessary in elderly patients, those with kidney or liver impairment, or those taking certain other medications.

Shelf Life of Viagra 50mg Tablet

Viagra 50mg Tablet typically has a manufacturer shelf life of up to 5 years from the date of production, though the specific expiry date will be printed on the outer carton and individual blister strips. Always check the expiry date before use and do not consume this medication past its stated expiration date. Once dispensed by a pharmacy, your pharmacist may indicate an expiry date on the label — in all cases, this date should be observed to ensure the medicine remains at its full potency and safety.

How to Store Viagra 50mg Tablet

Store Viagra 50mg Tablet at room temperature between 15°C and 30°C, in a cool, dry place away from direct sunlight, heat, and moisture. Keep the tablets in their original blister packaging until ready to use — do not transfer tablets to another container. Due to Malaysia's humid tropical climate, avoid storing this medication in bathrooms, near the kitchen sink, or in any area prone to humidity. Keep this medicine out of reach of children and pets at all times, and dispose of any unused or expired tablets safely in accordance with local pharmaceutical disposal guidelines.

Active Ingredient of Viagra 50mg Tablet

The active pharmaceutical ingredient (API) in Viagra 50mg Tablet is Sildenafil Citrate, equivalent to 50mg of sildenafil per tablet. Sildenafil citrate is a selective inhibitor of cyclic guanosine monophosphate (cGMP)-specific phosphodiesterase type 5 (PDE5), a well-characterised and extensively studied molecule in clinical medicine since its approval in 1998. In addition to the active ingredient, each Viagra tablet also contains the following inactive excipients: microcrystalline cellulose, anhydrous dibasic calcium phosphate, croscarmellose sodium, magnesium stearate, hypromellose, titanium dioxide, lactose, triacetin, and FD&C Blue No. 2 aluminium lake (indigo carmine) — which gives the tablet its distinctive blue colour.

Contraindications of Viagra 50mg Tablet

• Concurrent use of any form of organic nitrates or nitric oxide donors (e.g., glyceryl trinitrate / GTN, isosorbide mononitrate, isosorbide dinitrate) — this combination can cause a severe, life-threatening drop in blood pressure
• Concurrent use of guanylate cyclase (GC) stimulators such as riociguat (Adempas), used for pulmonary arterial hypertension — potentially dangerous hypotension may result
• Patients with a known hypersensitivity or allergy to sildenafil citrate or any inactive excipient in the tablet formulation
• Men for whom sexual activity is medically inadvisable due to underlying cardiovascular conditions (e.g., severe or unstable angina, severe heart failure, recent myocardial infarction within the past 3 months, or stroke within the past 6 months)
• Patients with severe hepatic (liver) impairment — sildenafil clearance is significantly reduced and plasma levels may become dangerously elevated
• Patients with severe hypotension (blood pressure below 90/50 mmHg) at baseline
• Patients with rare hereditary conditions such as retinitis pigmentosa — a rare degenerative eye condition that may predispose patients to serious visual adverse events
• Concurrent use of other PDE5 inhibitors (e.g., tadalafil, vardenafil, avanafil) or other treatments for pulmonary arterial hypertension containing sildenafil (e.g., Revatio) — combination increases risk of adverse effects
• Women and children — Viagra (sildenafil citrate at this indication and formulation) is not indicated for use in women or paediatric patients

Drug & Food Interaction of Viagra 50mg Tablet

Critical Drug Interactions — Do Not Combine Without Medical Guidance:

• Organic nitrates and nitric oxide donors (e.g., GTN patches, nitroglycerin spray, isosorbide mononitrate/dinitrate tablets) — STRICTLY CONTRAINDICATED. Combined use causes a severe, potentially fatal drop in blood pressure
• Riociguat (Adempas) and other guanylate cyclase stimulators — CONTRAINDICATED. May cause symptomatic hypotension
• Recreational drugs containing nitrates, including amyl nitrite or amyl nitrate ("poppers") — STRICTLY CONTRAINDICATED. Dangerous blood pressure drop

Drug Interactions Requiring Dose Adjustment or Caution:

• Alpha-blockers (e.g., doxazosin, tamsulosin, terazosin, alfuzosin) — may cause additive blood pressure lowering; if prescribed together, the starting dose of Viagra should be reduced to 25mg
• Strong CYP3A4 inhibitors — ritonavir (HIV protease inhibitor) can raise sildenafil blood levels up to 11-fold; maximum dose of 25mg within a 48-hour period is recommended
• Moderate CYP3A4 inhibitors — erythromycin, clarithromycin, ketoconazole, itraconazole, and saquinavir can significantly increase sildenafil plasma concentrations; a lower starting dose may be required
• Antihypertensive medications (e.g., amlodipine, other calcium channel blockers, beta-blockers) — additional blood pressure-lowering effects may occur; monitor blood pressure
• CYP3A4 inducers — rifampicin, phenytoin, carbamazepine, and phenobarbital may reduce sildenafil plasma concentrations and diminish effectiveness
• Other PDE5 inhibitors (tadalafil, vardenafil, avanafil) — do not combine; increases risk of adverse effects
• Bosentan (used for pulmonary arterial hypertension) — may reduce sildenafil exposure
• Cimetidine — may increase sildenafil plasma levels

Herbal & OTC Interactions:

• St. John's Wort (Hypericum perforatum) — a herbal supplement commonly used for mood support, it is a CYP3A4 inducer and may reduce the effectiveness of sildenafil
• Herbal products claiming to enhance sexual performance — avoid combining with Viagra without medical advice, as they may contain undisclosed active ingredients

Food & Drink Interactions:

• High-fat meals (e.g., nasi lemak, fried rice, heavy fast food) — consuming Viagra with a high-fat meal significantly delays its absorption and onset of action; it is best taken on an empty stomach or after a light meal for more predictable results
• Grapefruit and grapefruit juice — inhibit CYP3A4 enzymes and may increase sildenafil plasma levels, raising the risk of side effects; avoid grapefruit consumption around the time of taking this medication
• Alcohol — can independently lower blood pressure and impair sexual function; combining alcohol with Viagra increases the risk of dizziness, low blood pressure, and headaches. Excessive alcohol consumption should be avoided

Always provide your doctor and pharmacist with a complete list of all prescription medications, over-the-counter products, herbal supplements, and vitamins you are currently taking before starting Viagra 50mg Tablet.

Quick Tips for Viagra 50mg Tablet

• Viagra 50mg Tablet is a prescription-only medicine in Malaysia — always obtain a valid prescription from a registered doctor before purchasing and never self-prescribe or adjust your dose without medical advice.
• Never take this medication with any form of nitrate medicine (e.g., heart tablets or sprays for chest pain) — this combination can cause a dangerous and potentially fatal drop in blood pressure.

• Do not take more than one tablet within 24 hours under any circumstances.
• Avoid consuming grapefruit or grapefruit juice around the time of taking this medication, as it can increase the concentration of sildenafil in your blood and heighten the risk of side effects.
• Limit or avoid alcohol when taking this medication — alcohol can lower blood pressure further and increase the likelihood of dizziness, headache, and reduced effectiveness.
• If you experience a painful erection lasting more than 4 hours (priapism), seek emergency medical attention immediately — this is a medical emergency that requires prompt treatment.
