Cenforce 100, containing sildenafil citrate, is commonly used to treat erectile dysfunction. While effective, it may cause side effects such as headache, flushing, dizziness, nasal congestion, upset stomach, or blurred vision. In rare cases, it can lead to more serious effects like chest pain or prolonged erections. To manage side effects, take Cenforce as prescribed, stay hydrated, avoid alcohol, and consult a doctor if symptoms persist or worsen. Do not mix with nitrate medications, as this can cause a dangerous drop in blood pressure. Always follow medical advice for safe and effective use.
