The way it works
Sildenafil works by potentiating the effect of nitric oxide released during sexual stimulation. It inhibits the PDE5 enzyme in penile tissue, which leads to relaxation of smooth muscle and increased blood flow into the corpora cavernosa. Sexual arousal is still required for the medicine to have an effect.

Dose and administration directions
Follow the directions from your prescriber or pharmacist. Although P-Force Fort may be available in a 150 mg strength in some markets, clinicians usually start many patients at lower doses such as 25 mg or 50 mg and adjust according to effectiveness and peripheral effects. Do not self-adjust the dose without medical advice.
- Take the tablet about 30 to 60 minutes before planned sexual activity.
- Swallow the tablet whole with water; avoid crushing, splitting, or chewing unless a pharmacist confirms it is safe to do so.
- It can be taken with or without food; a high fat meal may delay the onset of action.
- Only one dose should be taken in a 24 hour period.
- Avoid grapefruit fruit or juice around the time of dosing because it can increase sildenafil levels.
If the effect seems too strong or too weak, contact your prescriber to discuss dose modification rather than changing the dose yourself.
Measures for safety

- Medical history: report any history of heart disease, previous stroke, irregular heart rhythm, chest pain, liver or kidney problems, eye conditions (for example hereditary retinal disorders), bleeding disorders, or stomach ulcers.
- Alcoholic content: excessive drinking can worsen dizziness and may reduce erectile response; limit intake if you plan to use sildenafil.
- Safety-sensitive tasks: dizziness or transient visual disturbances can occur; avoid driving or operating machinery if you are affected.
- Combination therapies: do not join these. sildenafil with other PDE5 inhibitors or penile devices without clinical advice.

Drug interactive engagement considerations
Sildenafil can interact with a range of medicines, sometimes causing dangerous drops in blood pressure or increased side effect risks. Always provide your prescriber with a full list of medicines, supplements, and over the counter products you use.
- Avoid concurrent use with nitrates and nitric oxide donors such as nitroglycerin or amyl nitrite, because the combination can cause severe hypotension.
- Strong CYP3A4 inhibitors including ketoconazole, itraconazole, clarithromycin, erythromycin, and certain HIV protease inhibitors can raise sildenafil levels and may require dose adjustments or avoidance.
- Alpha blockers and other blood pressure lowering agents may increase the risk of dizziness and fainting; dose timing and starting at lower doses is often advised.
- Do not take sildenafil alongside other PDE5 inhibitors such as tadalafil, vardenafil, or avanafil.
- Grapefruit products can elevate sildenafil exposure and increase lingering effects.
- Cimetidine (Tagamet) may increase sildenafil concentrations; a different route options could be considered.
The dose was missed
Sildenafil for ED is taken on an as-needed basis prior to sexual activity. If you forget to take it, do not take an extra dose to make up. Adhere to the instruction not to exceed one dose within any 24 hour period.
Overdose incident
Symptoms of taking too much sildenafil may include severe dizziness, fainting, prolonged or painful erection, nausea, or chest discomfort. If you suspect an suspected overdose, promptly seek medical attention or call emergency services.
