Sildamax 100 mg is a medication used to treat erectile dysfunction (ED) in men. It contains sildenafil citrate, which is the same active ingredient found in Viagra. Sildenafil citrate works by increasing blood flow to the penis during sexual stimulation, which helps men achieve and maintain an erection. Sildamax 100 mg is typically taken orally, about 30 minutes to 1 hour before sexual activity, and its effects can last for up to 4 hours. It's important to follow the dosage instructions provided by a healthcare professional and not to exceed the recommended dose. As with any medication, there are potential side effects associated with Sildamax 100, including headache, flushing, dizziness, upset stomach, and changes in vision. It's essential to discuss any existing medical conditions and medications with a doctor before starting Sildamax to ensure it's safe and appropriate for you.
