Forzest 20 mg is usually taken 30 to 60 minutes before sexual activity, although it may remain effective for a longer duration compared to some other ED medicines—often up to 24 to 36 hours. Because of this longer window, it allows more flexibility in timing sexual activity. This medicine does not increase sexual desire on its own; sexual stimulation is still required for it to work. The effectiveness of Forzest 20 mg can be influenced by factors such as alcohol consumption, smoking, stress, fatigue, and heavy or high-fat meals, which may reduce or delay its effect.
