Men with erectile dysfunction or male dysfunction can be treated with Fildena 120, sometimes known as "Weekend tablets". The active ingredient, sildenafil citrate, which helps improve blood flow to the penis and cause an erection, is present in this product in 120mg form. If you use this medication to treat pulmonary hypertension, make sure you adhere to the recommended dosage. If you take these pills to treat an erection problem, take them at least 30 to 60 minutes before engaging in sexual activity. Store any medications in a secure location out of the reach of kids and animals. Food can cause Fildena 120 to take longer to start working, therefore it works best when taken empty-handed.
