The duration of action of Fildena, which contains Sildenafil Citrate as its active ingredient, can vary from person to person. However, in general, the effects of Fildena typically last for about 4 to 6 hours after ingestion.

Here are some key points about the duration of action of Fildena:

Onset of Action: Fildena typically starts working within about 30 minutes to 1 hour after ingestion. The onset of action may vary depending on factors such as individual response, dosage strength, and whether the medication is taken on an empty stomach or with food.

Duration of Action: The effects of Fildena, including improved erectile function and the ability to achieve and maintain an erection suitable for intercourse, can last for up to 4 to 6 hours. This duration provides a suitable window of opportunity for sexual activity without the need for immediate dosing before intercourse.

Optimal Timing: To maximize the effectiveness of Fildena, it's generally recommended to take it about 1 hour before engaging in sexual activity. This allows sufficient time for the medication to be absorbed and start working.

Factors Affecting Duration: Several factors can influence how long the effects of Fildena last, including individual metabolism, overall health, presence of underlying medical conditions, dosage strength, and interaction with other medications.
