Overview of the topic

Suhagra is a brand name for tablets that contain sildenafil citrate. In Australia it is commonly prescribed to treat erectile dysfunction in adult men. Tablets are available in typical strengths such as 25 mg, 50 mg and 100 mg.

Different formulations and dosing regimens of sildenafil are used under specialist supervision to treat pulmonary arterial hypertension. Those products and schedules differ from the ones used for erectile dysfunction and require specific keeping track of metrics.

Suhagra is not approved to improve athletic performance and should not be used for that purpose.

How It Is Built and Licensed Uses

Sildenafil is a phosphodiesterase type 5 inhibitor. During sexual arousal the body releases nitric oxide which increases cyclic GMP in penile tissues. Sildenafil reduces the breakdown of cyclic GMP, helping smooth muscle to relax and allowing increased blood flow into the corpus cavernosum so an erection can occur with sexual stimulation.

Main approved uses include:

• Erectile dysfunction: taken before sexual activity to assist in achieving and maintaining an erection when sexually stimulated.
• Pulmonary arterial hypertension (PAH): specialist formulations and doses are used to lower blood pressure in the lungs; this is managed by respiratory or cardiology specialists.

Only use sildenafil for conditions diagnosed by a clinician. For practical instructions on when and how to take on new tasks the medicine see Dosing Instructions and Administration.

Dose and Administration Procedures

For erectile dysfunction sildenafil is generally used on an as-needed basis rather than as a daily therapy. Common prescribing principles are:

• Timing: take the tablet about 30 to 60 minutes before planned sexual activity. Some men notice effects as early as 15 minutes, others may need up to 4 hours.
• Starting dose: many prescribers begin at 50 mg and also then increase to 100 mg or reduce to 25 mg depending on effect and tolerability.
• A maximum of one dose in every 24-hour period.
• Food: heavy or fatty meals can slow absorption and delay onset. Taking the tablet on a lighter stomach may act sooner.
• Grapefruit: avoid grapefruit and grapefruit juice as they can raise sildenafil levels.
• Special groups: older adults and people with significant liver or kidney impairment may need lower starting doses and closer follow up.

Primary Safety Guidelines

• Allergy: do not take sildenafil if you are allergic to it or to any tablet ingredient.
• Cardiac history: inform your prescriber if you have had a recent heart attack, stroke, unstable angina, severe heart failure or irregular heart rhythms. Sexual activity may pose risks in these conditions.
• Vision and hearing: there are rare reports of sudden vision loss and sudden hearing decrease. Stop taking the drug and seek urgent care if these occur.
• Priapism: men with sickle cell disease, leukemia, multiple myeloma or penile structural abnormalities have higher risk of prolonged erections and should consult a specialist pre-use only.
• Bleeding or ulcers: use with caution in people with bleeding disorders or active peptic ulcer disease.
• Alcoholic beverage: excessive alcohol may increase dizziness and reduce erectile response.
• Operating machinery: if you experience dizziness or vision changes do not drive or operate heavy machinery.

Schedule a consultation the section about absolute exclusions Who Should Not Take It If There Is Any Risk.

Conditions precluding use - Who Should Not Take Suhagra

• Concurrent nitrate use: keep these separate; do not combine them. sildenafil with organic nitrates such as glyceryl trinitrate or isosorbide mononitrate/dinitrate, or with recreational nitrites. The combination can cause a dangerous drop in blood pressure.
• Riociguat and similar drugs: coadministration with soluble guanylate cyclase stimulators is not permitted.
• 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 for use in children.
• Known hypersensitivity: avoid use if you have a documented allergy to sildenafil or any excipient in the tablet.

Likely secondary effects and warning signs

Most individuals tolerate sildenafil with little difficulty. Additional effects are commonly mild and short lived.

• Regular reactions: tension headache, facial flushing, indigestion, nasal congestion, dizziness, nausea and diarrhea.
• Less widely used: visual changes such as increased sensitivity to light, blurred vision or a blue-green color tint, back pain, and skin rash.
• Rare but severe: chest pain, pronounced low blood pressure, an erection lasting longer than 4 hours (priapism), sudden loss of vision or hearing, and severe allergic reactions with swelling or breathing difficulty.

If you experience chest pain, fainting, sudden hearing or vision loss, or an erection lasting more than 4 hours seek urgent medical attention. For emergency steps after taking too much see An overdose case event and Emergency Preparedness Response Advice.

How Food Affects Drug Action

Sildenafil interacts with a range of medicines and some foods. Key interactive engagement opportunities to note include:

• Nitrates and nitrites: combining these with sildenafil can produce life threatening low blood pressure and is absolutely contraindicated.
• Riociguat: these items must stay separate and not be combined. with soluble guanylate cyclase stimulators.
• Alpha blockers and antihypertensives: these can increase the risk of symptomatic low blood pressure; clinicians may adjust doses or advise spacing.
• Strong CYP3A4 inhibitors: drugs such as ketoconazole, itraconazole, ritonavir, cobicistat and clarithromycin can raise sildenafil levels and may require a lower sildenafil dose.
• Enzyme inducers: rifampicin, carbamazepine, phenytoin and Saint John's wort may reduce sildenafil concentrations and make it less effective.
• Other PDE5 inhibitors: do not take sildenafil together with other erectile dysfunction medicines.
• Alcohol and grapefruit: alcohol may worsen dizziness and reduce response; grapefruit products can increase sildenafil blood levels and are best avoided.

Missed medication dose Action Plan

When used for erectile dysfunction sildenafil is taken as needed so a routine missed-dose procedure does not apply. If you are prescribed sildenafil on a regular schedule for PAH, take a i skipped a dose today as soon as you remember unless the next scheduled dose is close; do not double doses to catch up.

Overdosing episode Prevention and Guidance

Taking more than the recommended amount can cause severe dizziness, fainting, chest pain, irregular heartbeat, nausea or changes in vision. In Australia, if an overdosed on medication is suspected call emergency services on 000 or switch to the nearest emergency department without delay.

Australian legal study notes

• Scheduling: in Australia sildenafil for erectile dysfunction is a Schedule 4 prescription-only medicine regulated by the Therapeutic Goods Administration (TGA).
• Prescriptions: a valid Australian prescription is required to obtain sildenafil from an Australian pharmacy. Telehealth consultations may result in prescriptions when appropriate clinical assessment is completed.
• PBS and subsidies: erectile dysfunction medicines are generally not subsidised under the Pharmaceutical Benefits Scheme. Sildenafil used for PAH may be subsidised in certain formulations and situations.
• Personal importation: under the TGA Personalised Importation Scheme individuals may import up to three months supply of a prescription medicine for personal use if they hold a valid prescription. Importing medicines without required documentation risks seizure and within reach exposure to counterfeit products.
• Advertising: direct-to-consumer advertising of prescription medicines is restricted situated within Australia. Seek personalised guidance from a registered clinician.
• Athletes: PDE5 inhibitors are not typically banned by World Anti-Doping Agency, but athletes should check sport-specific regulations before using any medication.
• Safety reminder: do not take another person’s prescription. If you have chest pain during sexual activity after taking sildenafil stop and seek emergency care immediately.
