Overview and scope
Suhagra contains the active substance sildenafil citrate and is a commonly prescribed option for erectile dysfunction in adult men. It is supplied as film-coated tablets in typical strengths of 25 mg, 50 mg and 100 mg.
Under different formulations and dosing schedules, sildenafil is also used to treat pulmonary arterial hypertension (PAH). That indication uses different preparations and prescriber routines compared with erectile dysfunction therapy.
Note: sildenafil is not approved as a performance enhancing agent for athletes and is not generally recommended to improve sporting performance.
The the control mechanism by which Suhagra works and its approved manifestations
Sildenafil reduces phosphodiesterase type 5 activity. When sexual arousal occurs, nitric oxide release increases cyclic GMP in the erectile tissue. Sildenafil reduces the breakdown of cyclic GMP, which promotes smooth muscle relaxation and increased blood flow to the corpus cavernosum, facilitating erection when sexual stimulation is present.
- Erectile dysfunction: taken as required to assist erectile response during sexual activity.
- Pulmonary arterial hypertension: available under specialist supervision in different doses and formulations tailored to PAH.
Use only for signs that indicate prescribed by a clinician. For more on dosing, see Take as directed: dosage directions.
Take as directed: dosage directions
For erectile dysfunction, sildenafil is most often used on an as-required basis rather than on a fixed daily schedule. Usual prescribing principles include:
- Timing: typically taken 30 to 60 minutes before sexual activity; some men notice effects from 15 minutes, while others may need up to 4 hours.
- Starting dose: 50 mg is a common starting point. Based on effect and tolerability a prescriber may lower to 25 mg or increase to 100 mg.
- One dose per 24 hour period at most.
- Food interpersonal engagements create context for decisions.: a large fatty meal can delay onset; taking it without a heavy meal may produce quicker action.
- Grapefruit: avoid grapefruit or grapefruit juice as they can raise blood levels of sildenafil.
- Special populations: older adults and people with significant liver or kidney impairment may require lower starting doses or more careful watchful oversight.
Swallow the tablets intact with water. Remember, sexual stimulation is required for sildenafil to work. For input related to contact and response concerns, see the guide. Nutritional the pattern of the back and forth between peoples determines group dynamics. with medicines.
Safety guardrails
- Allergy: do not use if you are known to be allergic to sildenafil or any excipients in the tablet.
- Cardiovascular history: inform your prescriber if you have had recent heart attack, stroke, unstable angina, severe heart failure, or significant arrhythmia. Sexual activity can be risky in some heart conditions.
- Vision or hearing changes: rare cases of sudden vision loss from non-arteritic anterior ischemic optic neuropathy and sudden hearing decrease have been reported; stop the medicine and seek urgent medical help if these occur.
- Priapism risk: men with sickle cell disease, multiple myeloma, leukemia, or penile structural abnormalities are at higher risk of prolonged erection and should consult a specialist prior to use.
- Bleeding and ulcers: caution in people with bleeding disorders or active peptic ulcer disease.
- Ethanol-based drink: excessive alcohol increases the chance of dizziness or low blood pressure and may blunt erectile response.
- Driving and machinery: if you experience dizziness or visual disturbance, avoid driving or operating machines.
For guidance on contraindicated situations see Who should stay away from using it.
Who should not be using Suhagra
- Concurrent nitrates: do not use sildenafil if you take any nitrate medicines (for example glyceryl trinitrate, isosorbide mononitrate or dinitrate) or recreational nitrites (poppers) because of the risk of a dangerous drop in blood pressure.
- Riociguat and similar agents: combination with soluble guanylate cyclase stimulators is contraindicated.
- Severe hypotension or unstable cardiac disease: recent heart attack, stroke, unstable angina or very low blood pressure make sildenafil unsafe unless a specialist advises otherwise.
- Not indicated for women or children for erectile dysfunction.
- Known hypersensitivity to sildenafil or any component of the product.

- Riociguat: concomitant use is not permitted.
- Alpha blockers and other blood pressure medicines: may cause additive reductions in blood pressure; your prescriber may lower doses or separate timing.
- Strong CYP3A4 inhibitors: agents such as ketoconazole, itraconazole, ritonavir, cobicistat and clarithromycin can increase sildenafil exposure and may require dose adjustment.
