Avana 100 mg, which contains avanafil, is primarily prescribed as an on-demand treatment for erectile dysfunction (ED), not as a routine preventative medication. However, some specialists may consider it “preventative” in certain situations where early or regular use helps maintain erectile function. For example, men who have undergone prostate surgery, diabetes management, or cardiovascular conditions may be advised to take PDE5 inhibitors like Avana 100mg occasionally to prevent long-term deterioration of penile tissue and support healthy blood flow. In this sense, its role is more rehabilitative and preventative of ED progression rather than preventing sexual problems before they appear. It is important that such use is strictly supervised by a healthcare professional, as it is not standard practice for every patient.
