- Typical strength available from some suppliers: 100 mg sublingual tablet (availability varies)

How It Functions
Sildenafil suppresses PDE5 activity. By reducing PDE5 activity, cyclic GMP is maintained longer in penile tissue during sexual stimulation, leading to increased blood flow into the corpora cavernosa and supporting an erection. It does not produce sexual desire by itself and is not a hormone or aphrodisiac.

Ways to Use This
Follow the prescribed directions from your prescriber or pharmacist. General guidance for sublingual sildenafil:
- Timing: Usually taken on demand about 15 to 30 minutes before sexual activity. Some men report benefit when taken up to 4 hours earlier.
- Administration: Place the tablet under the tongue and allow complete dissolution. Do not chew or swallow immediately to encourage sublingual absorption.
- Food effects: Can be taken with or without food. A heavy or fatty meal may delay onset for some people.
- Maximum frequency: Do not take more than one dose in any 24-hour period unless instructed otherwise by a clinician.
- Dose selection: Use the lowest dose that produces the desired effect. Do not adjust the amount without professional sound advice.
Missed dose event: There is no regular dosing schedule for as-needed ED medicines, so missed-dose rules do not apply.

High priority drug nutrient the act of engaging in dialogues in the user journey shape satisfaction. and effects
- Strong CYP3A4 inhibitors (for example ritonavir, cobicistat, ketoconazole, itraconazole, clarithromycin) can increase sildenafil blood levels; dose adjustment or avoidance may be required.
- CYP3A4 inducers (for example rifampicin, carbamazepine, phenytoin, The medicinal herb St Johns wort) may reduce effectiveness.
- Alpha-blockers and other antihypertensives can increase the risk of symptomatic low blood pressure or fainting.
- Grapefruit or grapefruit juice can raise sildenafil concentrations and should be avoided while taking the medicine.

Alcoholic drink and Activity Related Guidance
Hard liquor might increase dizziness, cause blood pressure to fall, and impair sexual response. Until you know how sildenafil affects you, avoid driving, operating machinery, or performing tasks that require full alertness. Heat, fever, or vigorous exercise can accentuate lightheadedness; rise slowly from sitting or lying positions.
Emerging Risks and Urgent alert signals
Stop taking sildenafil and seek urgent medical help if you experience signs of a heart attack or stroke, sudden loss of vision or hearing, or a persistent and painful erection lasting 4 hours or more (priapism). These events require immediate attention to reduce the risk of permanent injury.
In case of an emergency in Australia, dial 000. For poisoning or exposure advice call the Poisons Information Centre on 13 11 26.

- Advertising rules: Prescription medicines may not be advertised to the public in the Australian continent. Be cautious of promotional claims that conflict with TGA regulations.
- Age and driving: Products are intended for adult men. Do not drive or operate heavy machinery if the medicine causes dizziness or reduced alertness; Australian road rules require fitness to drive.
- Sporting considerations: PDE5 inhibitors are generally not on banned lists used by anti-doping authorities, but competitive athletes should confirm compliance with their sport's rules and Sport Integrity Australia advice.
