Active ingredient: Sildenafil citrate is a phosphodiesterase type 5 (PDE5) inhibitor. It works by relaxing the muscles in the blood vessel walls, increasing blood flow to the penis.
Mechanism: During sexual arousal, nitric oxide is released into the erectile tissue of the penis. Nitric oxide activates the enzyme guanylyl cyclase, which results in increased levels of cyclic guanosine monophosphate (cGMP). cGMP relaxes smooth muscle cells and increases blood flow to penile tissue, resulting in an erection. Sildenafil citrate enhances this process by inhibiting the PDE5 enzyme, which breaks down cGMP.

Dosage: The recommended dose is to take one 100 mg tablet approximately 30-60 minutes before sexual activity.
Directions for Administration: Swallow the tablet whole with water. It can be taken with or without food, but high-fat meals may delay the onset of action.
Duration: Effects last approximately 4-6 hours. Do not take more than 1 tablet in 24 hours.
effect:
Improved Erection: Fildena 100mg helps men achieve and maintain an erection sufficient for intercourse. Although it does not increase sexual desire, it increases the erectile response to sexual stimulation.
Success Rate: Many ED patients find sildenafil citrate effective. However, individual responses may vary and some men may require different doses or alternative treatments.

Common side effects: May include headache, flushing, indigestion, nasal congestion, dizziness, and visual disturbances (such as changes in color vision).
Serious side effects: Rare but serious side effects include sudden loss of vision or hearing, an erection that lasts for more than 4 hours (priapism), and severe allergic reactions. If any of these occur, seek immediate medical attention.

Medical history: Give your doctor your complete medical history, especially if you have heart problems, high or low blood pressure, liver or kidney disease, or other serious medical conditions.
Interactions: Fildena can interact with certain medications, such as nitrates (used for chest pain) and alpha blockers (used for high blood pressure and prostate disease), causing a potentially dangerous drop in blood pressure. It may also interact with other PDE5 inhibitors and certain antifungals and antibiotics.
Alcohol: Limit your alcohol intake as it may increase your risk of side effects and make your medicine less effective.

Allergies: Do not take Fildena if you are allergic to sildenafil citrate or any other ingredient in the tablet.
Other medicines: Avoid using Fildena if you are taking medicines that contain nitrates or nitric oxide donors.
