Avana 100 mg, which contains avanafil. Avanafil is a medication used to treat erectile dysfunction (ED). Like tadalafil (Tadarise), it works by increasing blood flow to the penis, helping to achieve and maintain an erection when sexually aroused. Avana 100 mg is one of the higher doses of this medication. It usually takes effect within about 15 to 30 minutes after taking it and can last for up to 6 hours. However, it’s important to note that it only works when you're sexually aroused, and it doesn’t increase sexual desire. Some important things to remember: Dosage: Typically, the starting dose is 50 mg, but doctors may Avana 100 mg  if it's deemed appropriate for the individual’s needs. Side Effects: Some common side effects include headaches, flushing, nasal congestion, dizziness, and in some cases, back pain or muscle aches. Precautions: It's crucial not to take this with other ED medications or certain other drugs, especially nitrates (often used for chest pain), because it can cause a dangerous drop in blood pressure. If you're considering this medication or have concerns, it's essential to talk to a doctor first. They can provide guidance and ensure it's the right choice for you.
