Fildena 100 mg

(10 customer reviews)

Fildena 100 mg is a prescription medication designed to treat erectile dysfunction (ED) in men. Each tablet contains 100 mg of Sildenafil Citrate, the same active ingredient used in Viagra. The medication works by increasing blood flow to the penis, enabling men to achieve and maintain a firm erection during sexual activity. The effects typically begin within 30 to 60 minutes and can last for up to 4 hours, with the peak effect usually occurring around one hour after intake. Consuming a heavy or high-fat meal may delay its onset, and sexual stimulation is necessary for the medicine to be effective. Manufactured by Fortune Healthcare, Fildena 100 mg is recognised for its reliable performance. Each pack contains 10 tablets for convenient use, and the medication should be taken under medical supervision.

What is Fildena 100?

Fildena 100 mg is a phosphodiesterase type 5 (PDE5) inhibitor that improves blood flow to the penis during sexual arousal, helping men achieve and maintain a firm erection. It’s commonly known as a generic alternative to Viagra.

What is Fildena 100 mg used for?

Fildena 100 mg is primarily used for the treatment of erectile dysfunction (ED), a condition that makes it difficult for men to achieve or maintain an erection. It improves erectile function during sexual stimulation. It is not used for conditions like pulmonary arterial hypertension (PAH), for which lower-dose sildenafil is approved. Using Fildena 100 for PAH or combining it with other sildenafil-containing medications can result in overdose and serious complications.

How Does Fildena 100 mg Work?

Fildena 100 mg works by enhancing blood flow to the penis during sexual arousal through the inhibition of the PDE5 enzyme. Each tablet contains 100 mg of sildenafil citrate, a phosphodiesterase type 5 (PDE5) inhibitor. This class of medication facilitates erection by preserving the levels of cyclic guanosine monophosphate (cGMP) in the penile tissue.

During sexual stimulation, nitric oxide is released into the corpus cavernosum of the penis. This triggers the production of cGMP, which relaxes smooth muscle and dilates blood vessels. The result is increased blood flow and a firmer erection. Sildenafil blocks PDE5, the enzyme that normally breaks down cGMP, thereby prolonging its action and sustaining the erection.​

How Long Does Fildena 100 mg Last?

The effects of Fildena 100 mg typically last between 4 to 6 hours after ingestion. It begins to work within 30 to 60 minutes, though factors such as metabolism, food intake, and overall health can impact its onset and duration. Remember, sexual stimulation is necessary for the medication to produce an erection, even during its effective window.

The recommended dosage is one Fildena 100 mg tablet taken as needed, approximately 30 to 60 minutes before sexual activity. It should not be taken more than once per day. Patients who are new to sildenafil should consult a healthcare provider before using this dose, as a lower strength might be more appropriate initially. Dosage adjustments should only be made under medical supervision.​

How to Take Fildena 100 mg?
