Fildena 150 is a higher dosage of the medication used to treat erectile dysfunction (ED), containing 150 mg of sildenafil citrate. Like Fildena 100, it works by increasing blood flow to the penis, helping to achieve and maintain an erection in response to sexual stimulation. Fildena 150 should be taken about 30 to 60 minutes before sexual activity. It is generally not recommended to take more than one dose per day. The effects can last for up to four to five hours. It's important to follow your healthcare provider's instructions precisely. Taking more than the prescribed dose can increase the risk of side effects.
