Executive Product Summary
Active moiety: sildenafil, commonly presented as sildenafil citrate. The medicine shown here is discussed in a 150 mg tablet strength.
Indication: licensed to treat erectile dysfunction in adult males. Sildenafil is a selective phosphodiesterase type 5 inhibitor that helps enhance blood flow to the penis when sexual stimulation is present. It does not induce sexual desire on its own and will not produce an erection without sexual arousal.
Typical onset can be seen from about 30 to 60 minutes after dosing, with clinically relevant effects lasting roughly 4 to 6 hours, although individual response varies. For safety reasons, avoid combining this product with nitrate medications or nitric oxide donors. Take in the Protective actions and exclusions for therapy and Drug Interaction Advisory Alerts for specifics.
Dosing and Drug Administration
The following guidance is general. A prescriber should tailor dosing to your medical status and response.
- Take one tablet orally with water about one hour before planned sexual activity.
- Swallow tablets whole; do not crush, chew, or split unless the prescriber instructs otherwise.
- Limit dosing to one tablet in any 24-hour period.
- A heavy or fatty meal may delay how quickly the medicine starts to work.
- Follow a healthcare professional's directions and do not share prescription tablets.
Note: United States FDA-approved labeling for sildenafil for erectile dysfunction typically recommends a maximum single dose of 100 mg. The 150 mg strength referenced here exceeds the standard U.S. maximum and should only be used under close medical supervision after careful risk-benefit assessment by a knowledgeable prescriber.
Many clinicians start patients at 50 mg and adjust upward or downward based on effectiveness and tolerability. Questions about timing or combining therapies should be discussed with your clinician and critiqueed against the Safety oriented risk controls and Alerts of Potential Drug Interaction Effects.
Safety protective measures & Safety

- Grapefruit juice may raise blood levels of sildenafil and increase side effect risk; limit intake.
- If you feel dizzy or faint after taking a dose, do not drive or operate machinery until you are sure you are not impaired.
- Coordinate use with your prescriber if you take alpha-blockers or antihypertensive medications due to potential additive blood pressure lowering.
- Stop use and seek medical advice if you have a known allergy to sildenafil or any tablet excipient.
Drug Interaction Keeping under surveillance Alerts
Sildenafil can interact with many medicines. The list below highlights commonly salient interplay between partiess fuel collaboration and innovation. but is not exhaustive. Check with your healthcare team for a complete review.
- Nitrate compounds (for example, nitroglycerin or isosorbide mononitrate): combining with sildenafil can cause severe, possibly life-threatening low blood pressure. This combination is contraindicated; see Reasons to avoid use.
- Riociguat: avoid concomitant use because of potential marked hypotension.
- Other erectile dysfunction agents (tadalafil, vardenafil, avanafil or injectable/topical ED therapies): please keep them separate and not combined. unless under specialist advice.
- Strong CYP3A4 inhibitors (such as ritonavir, ketoconazole, itraconazole, atazanavir, certain macrolide antibiotics): these can raise sildenafil exposure and may require dose reduction or close system monitoring.
- CYP3A4 inducers (for example, rifampin, carbamazepine, phenytoin, St. Johns wort): these may lower sildenafil levels and reduce effectiveness.
- Many blood pressure medicines and alpha-blockers: combined effects can increase the risk of symptomatic hypotension; discuss timing and continuous oversight by consulting your prescriber.
- Products containing grapefruit or grapefruit juice: may increase systemic sildenafil concentration.
Absolute the contraindicated conditions for this procedure
Do not take sildenafil if any of the following apply unless a clinician has determined the benefit outweighs the risk:
- You are using nitrate medications or recreational inhaled nitrites.
- Concurrent use with riociguat or other agents that substantially lower systemic blood pressure.
- You have recently experienced a heart attack, stroke, or have unstable cardiac disease.
- You have marked hypotension or uncontrolled hypertension.
- Severe hepatic injury or end-stage renal disease without specialist oversight.
- Certain hereditary retinal disorders (for example, retinitis pigmentosa) or a history of non-arteritic anterior ischemic optic neuropathy.
- Use of supplements or products that contain high-dose nitrates, sometimes marketed for exercise enhancement.

US Legal Considerations
- Prescriptions required: In the United States sildenafil for erectile dysfunction is a prescription-only medication; no FDA-approved over-the-counter sildenafil exists for ED.
- Purchase from licensed sources: Obtain medicines from state-licensed pharmacies or reputable telehealth providers with a valid prescription. Look for accreditation and verification when buying online.
- Importation rules: Bringing prescription drugs into the United States from foreign vendors is generally restricted. The FDA can detain unapproved foreign products and U.S. Customs may seize shipments. Products intended for other markets may not meet U.S. safety, efficacy, or labeling standards.
- Counterfeit risk: Unverified online sellers pose a higher risk of counterfeit, contaminated, or substandard products. Prefer state-licensed pharmacies and known telehealth platforms to minimize the chance of problems.
- Telemedicine practices: E-prescribing via telehealth is common but must comply with federal and state laws. Providers should verify identity and medical appropriateness in line with state practice rules.
If cost is a barrier, consult a clinician or pharmacist about generic variant options or assistance programs rather than importing products of uncertain quality or legality. To find guidance on price levels, navigate to the rate schedule this section. Estimated Prices (USA).
