“Viagra”: options and how to choose the right one

Disclaimer: This material is for educational purposes only and does not replace consultation with a qualified healthcare professional. Erectile dysfunction (ED) may be associated with cardiovascular, endocrine, neurological, or psychological conditions. Do not start or change treatment without medical advice.

Who needs it and what goals are common

Viagra (sildenafil) is a prescription medication used to treat erectile dysfunction—difficulty achieving or maintaining an erection sufficient for sexual activity. The main goals of therapy vary:

• Restore reliable erectile function.
• Improve confidence and quality of life.
• Support intimate relationships.
• Address ED related to stress, chronic disease, or lifestyle factors.

Men with diabetes, hypertension, cardiovascular disease, obesity, sedentary lifestyle, or high stress levels often report ED symptoms. Athletes and physically active men may also experience performance-related anxiety, which is discussed in our Sports health insights section.

Common mistakes and misconceptions when choosing

• Assuming higher dose = better effect. Overdosing increases side effects without guaranteed benefit.
• Ignoring cardiovascular health. ED may be an early marker of vascular disease.
• Buying from unverified online sources. Risk of counterfeit medication.
• Expecting automatic erection. Sexual stimulation is still required.
• Stopping after one attempt. Effectiveness may vary depending on context and timing.

Mini-guide to preparing for a consultation

Bring or prepare:

• List of current medications and supplements.
• History of chronic diseases (diabetes, hypertension).
• Recent lab results (lipid panel, glucose, testosterone if available).
• Blood pressure records.

Track symptoms:

• Duration and frequency of ED.
• Presence of morning erections.
• Stress levels or relationship factors.

Questions to ask:

• Is my ED likely physical, psychological, or mixed?
• Which dose is appropriate?
• Are there safer alternatives considering my health profile?
