Sildisoft is typically taken 30–60 minutes before sexual activity, though it can be taken up to 4 hours prior. The usual starting dose is 50 mg, but it can be adjusted to 25 mg or 100 mg based on effectiveness and tolerance. Importantly, sexual stimulation is required for the medication to work—it does not automatically cause an erection. The tablets are generally well-tolerated, but some common side effects may include headache, flushing, dizziness, nasal congestion, or mild digestive discomfort. https://www.genericday.com/sildisoft-tablets.html
