Fildena 100 mg, which contains sildenafil citrate, typically begins to show its effects within 30 to 60 minutes after ingestion. However, the full effect may take up to 1 hour to manifest, depending on factors such as individual metabolism and whether the tablet is taken with food. If taken on an empty stomach, the medication tends to work faster, as a high-fat meal can delay the onset of action.

Once effective, Fildena 100 mg enhances blood flow to the penis during sexual stimulation, helping men with erectile dysfunction (ED) achieve and maintain an erection. The effects can last for up to 4 to 6 hours, but it is important to note that the drug will not cause an erection without sexual arousal.

It’s recommended to avoid taking more than one tablet per day and to follow the prescribed dosage to prevent potential side effects. For optimal results, the medication should be taken as directed by a healthcare provider, who can guide proper usage based on individual health conditions.

If you don't experience the desired effect, or if side effects occur, consulting a doctor is crucial for adjusting the treatment plan.
