Viagra, or sildenafil, is suitable for men diagnosed with erectile dysfunction (ED) who are at least 18 years old. Your doctor will assess your overall health to determine suitability. Men with certain conditions should avoid Viagra.
Conditions Precluding Viagra Use:
Men with heart conditions, including uncontrolled high blood pressure or angina, should not use Viagra. This includes those with a history of heart attack or stroke within the past six months. Similarly, Viagra is contraindicated for men with uncontrolled blood pressure or severe liver or kidney problems. Patients taking certain medications, such as nitrates used to treat angina, are also ineligible. A history of vision problems like non-arteritic anterior ischemic optic neuropathy (NAION) is a significant contraindication. Men with a known allergy to sildenafil or its components must also avoid Viagra. Finally, it’s crucial to disclose any current medications to your doctor.
Who Benefits Most?
Viagra primarily helps men experiencing ED caused by physical factors, such as circulatory issues. It can significantly improve the ability to achieve and maintain an erection. Your doctor will discuss your medical history and lifestyle to determine if Viagra is the right treatment for you. They will also explain potential side effects and provide guidance on appropriate dosage.
