Fildena 150 mg is another variant of the medication containing sildenafil citrate, commonly used to treat erectile dysfunction (ED) in men. Like Fildena 100 mg, the 150 mg strength is used to help men achieve and maintain an erection during sexual activity. The recommended dosage and frequency of Fildena 150 mg, as well as any other dosage strength, should be determined by a healthcare professional based on individual health factors. Generally, it is advised to take the medication about one hour before anticipated sexual activity. The effects of sildenafil typically last for about 4 to 6 hours.
