The big picture view
Suhagra is a trade name for tablets containing sildenafil citrate. It is widely used in adult men to treat erectile dysfunction and is available in common tablet strengths such as 25 mg, 50 mg and 100 mg.
In other formulations and under specialist supervision, sildenafil is also prescribed for pulmonary arterial hypertension (PAH). Those PAH preparations, doses and metric monitoring differ from the regimens used for erectile dysfunction.
Important: sildenafil is not licensed to enhance athletic performance and is not recommended for that purpose.

How the system works and Licensed Uses
Sildenafil belongs to a class called phosphodiesterase type 5 inhibitors. During sexual arousal, nitric oxide increases cyclic GMP in penile tissue. Sildenafil slows the breakdown of cyclic GMP, which helps smooth muscle relax and increases blood flow to the corpus cavernosum, enabling erection when sexual stimulation occurs.
- Erectile dysfunction: typically prescribed to be taken before sexual activity to assist erection.
- Pulmonary arterial hypertension: used in different formulations and doses under specialist care for PAH.
Only use sildenafil for conditions your clinician has diagnosed and prescribed. For practical guidance on taking the medicine see Dosing Protocols and Administration.
Administration and Dosing
For erectile dysfunction the medicine is usually taken as needed rather than every day. Typical prescribing principles include the following.
- When should this be taken: allow 30 to 60 minutes before sexual activity; some men notice effects after 15 minutes while others may need up to 4 hours.
- Usual starting dose: clinicians often begin at 50 mg merged with then adjust to 25 mg or 100 mg based on response and negative effects.
- Maximum frequency: do not take more than one dose within 24 hours.
- Effect of food: large fatty meals can slow absorption and delay onset; taking it on an emptier stomach may act sooner.
- Grapefruit warning: avoid grapefruit and grapefruit juice as they can raise sildenafil blood levels.
- Special populations: older adults or people with significant liver or kidney problems may need lower starting doses and closer watchful oversight.
With water, swallow the tablets. Remember that sexual stimulation is required for the medicine to work. If you have concerns about the act of engaging in dialogues create context for decisions. see Meals and Medication Human global teams rely on robust the act of engaging in dialogues..
Key Safety Instructions
- Allergic reactions: do not use if you know you are allergic to sildenafil or any tablet ingredients.
- Heart health: tell your prescriber if you have had a recent heart attack, stroke, unstable angina, serious heart failure or irregular heart rhythms. Sexual activity plus these conditions may carry risk.
- Vision or hearing changes: rare reports of sudden vision loss from non-arteritic anterior ischemic optic neuropathy and of sudden hearing decrease exist; stop treatment and seek urgent care if these occur.
- Priapism risk: men with sickle cell disease, leukemia, multiple myeloma or penile structural problems have increased risk of prolonged erection and should get specialist advice first.
- Bleeding or ulcers: use caution if you have bleeding disorders or active peptic ulcer disease.
- Spirituous beverage: drinking large amounts of alcohol can increase dizziness and reduce erectile response.
- Driving and machinery: if you experience dizziness or vision changes do not drive or operate heavy machines.

- Riociguat and similar drugs: coadministration with soluble guanylate cyclase stimulators is contraindicated.
- Unstable cardiovascular disease or very low blood pressure: recent myocardial infarction, stroke, unstable angina or severe hypotension make use unsafe unless a specialist advises otherwise.
- Women and children: sildenafil is not indicated for erectile dysfunction in women or children.

Risky effects and red flags

Meals and Medication Interpersonal engagements
- Nitrates and nitrites: absolute contraindication due to the risk of life threatening hypotension.
- Riociguat: combining with soluble guanylate cyclase stimulators is not permitted.
- Alpha blockers and other antihypertensives: may add to blood pressure lowering effects; doctors may alter doses or advise interval separation.
- Strong CYP3A4 inhibitors: medicines such as ketoconazole, itraconazole, ritonavir, cobicistat and clarithromycin can raise sildenafil levels and may require dose reduction.
- Enzyme inducers: rifampicin, carbamazepine, phenytoin and Hypericum perforatum can reduce sildenafil concentrations and lower effectiveness.
- Other ED drugs: do not fuse these together. sildenafil with other PDE5 inhibitors or other erectile dysfunction agents.
- Ethanol solution and grapefruit: alcohol can worsen dizziness and lower blood pressure; grapefruit products can increase blood concentrations and should be avoided.
Guidance for a Untaken medication dose
For erectile dysfunction, sildenafil is taken when required so a routine missed-dose procedure is not applicable. If sildenafil is prescribed on a regular schedule (for PAH), take a the dose was skipped as soon as you remember unless the next dose is almost due. Do not double up on doses to make up for a missed one.
Excessive dose of medication Alert and Response Guidelines

If an non-fatal overdose is suspected in Australia call emergency services on 000 or attend the nearest emergency department immediately.

Australian law briefing notes
- Scheduling: In Australia sildenafil for erectile dysfunction is classified as a Schedule 4 prescription-only medicine and is regulated by the Therapeutic Goods Administration (TGA).
- Prescriptions: A valid Australian prescription is required to obtain sildenafil from an Australian pharmacy. Telehealth clinicians may supply prescriptions where clinically appropriate.
- PBS and subsidies: Erectile dysfunction treatments are usually not subsidised under the Pharmaceutical Benefits Scheme (PBS). Sildenafil for PAH may be subsidised in specific strengths and situations, but this does not typically cover ED doses.
- Personal importation: Under the TGA Individual Importation Program an individual may import up to three months supply of a prescription medicine for personal use if they hold a valid prescription. Medicines imported without appropriate prescriptions risk seizure by Border Force and may be counterfeit or unsafe.
- Advertising: Direct-to-consumer promotion of prescription medicines is restricted in the Australian continent. Seek personalised advice from a registered clinician.
- Athletes: PDE5 inhibitors are generally not on the World Anti-Doping Agency prohibited list, but athletes should confirm current sport-specific rules before using any medication.
- Safety reminder: Never take another person's prescription. If you experience chest pain during sexual activity after taking sildenafil, stop and seek emergency care immediately.
