Both Viagra (sildenafil) and Cialis (tadalafil) are popular options for treating erectile dysfunction. Viagra tends to work quickly and is taken as needed, while Cialis can last longer and is often preferred for its flexibility. Many people find these medications effective, but side effects can include headaches, flushing, or dizziness. It’s important to consider any health conditions you have and discuss with a doctor. For natural remedies, some try lifestyle changes like diet, exercise, or supplements like L-arginine, but these can vary in effectiveness. Always consult a healthcare professional before starting any treatment.
