Erectile dysfunction (ED) in men is treated using the drug Bigfun 100 mg. A man with ED struggles to obtain or maintain an erection during sensual engagement. This contains sildenafil citrate, a phosphodiesterase type 5 (PDE5) inhibitor. Bigfun 100 mg works by boosting blood flow to the male genital organ. During sensual activity, the genital organ can get and maintain an erection because of the increased blood flow. The effects can last up to 4 hours and should be taken between 30 and 60 minutes prior to engaging in sensual activities. It's critical to adhere to your doctor's dosage recommendations. It shouldn't be used more than once a day, and it shouldn't be combined with alcohol or other recreational drugs. Bigfun 100 mg should not be taken by anyone who has specific medical concerns like liver or kidney issues, cardiac issues, or a history of stroke or heart attack without first visiting a doctor. Headache, flushing, upset stomach, and nasal congestion are typical side effects of Bigfun 100 mg.
