Cenforce 150 (sildenafil 150 mg) can cause flushing. Why it happens Sildenafil widens blood vessels (vasodilation). This increases blood flow to the skin, especially the face and neck. The result is a warmth, redness, or “flushed” feeling. How common is it? Flushing is a common side effect of sildenafil at doses like 150 mg. Higher doses generally increase the likelihood and intensity of side effects compared to lower doses (e.g., 50 mg or 100 mg).
