If Malegra Oral Jelly contains sildenafil, the active drug has a half-life of about 4 hours. That means the amount in your body falls by roughly half every 4 hours. As a rough guide: 4 hours: ~50% remains 8 hours: ~25% 12 hours: ~12.5% 16 hours: ~6% 20–24 hours: only a small amount remains So, for most healthy adults, most Malegra Oral Jelly is effectively cleared within about 20–24 hours. The exact time can be longer with liver/kidney problems or certain interacting medicines. The erectile effect doesn't last as long as the drug remains in the body—sildenafil is generally used once per day. If you tell me the strength of your Malegra Oral Jelly (e.g., 50 mg or 100 mg) and what time you took it, I can estimate how much is likely still in your system now.
