Fildena 150 mg is a medication primarily used to treat erectile dysfunction (ED) in men. It contains 150 mg of Sildenafil Citrate, which is a phosphodiesterase type 5 (PDE5) inhibitor that helps increase blood flow to the penis, facilitating an erection when sexually stimulated. Patients should not exceed one tablet within 24 hours to avoid potential overdose and side effects. Taking Fildena with a heavy meal may delay its onset of action, so it is advisable to take Fildena 150 on an empty stomach or after a light meal.
