Who qualifies for Viagra

Our EU-licensed doctors review each case individually to determine if Viagra is the right treatment for you. They look for specific criteria and potential contraindications to ensure your safety and the effectiveness of the treatment. Generally, you may qualify if you experience consistent difficulty achieving or maintaining an erection firm enough for sexual activity. Factors the doctor considers include:

• Overall Health: Your general health status, including any pre-existing conditions like heart disease, high blood pressure, or diabetes.
• Medication History: A review of all medications you currently take, as some can interact negatively with Viagra.
• Specific Contraindications: Viagra is not suitable if you take nitrates (often prescribed for chest pain) or alpha-blockers (for prostate issues or high blood pressure), as this can cause a dangerous drop in blood pressure.
• Absence of Severe Liver or Kidney Issues: These conditions can affect how your body processes the medication.

The doctor's primary goal is to ensure Viagra is safe and effective for your specific health profile.

What Viagra actually does (and doesn't do)

Viagra (sildenafil) is a medication designed to help you achieve and maintain an erection when you are sexually aroused. It works by increasing blood flow to the penis. When you take Viagra and are sexually stimulated, it relaxes the blood vessels in your penis, allowing more blood to flow in, which leads to an erection. It does not create sexual arousal on its own; you still need to be stimulated for it to work.

You typically take Viagra about 30 to 60 minutes before sexual activity. Its effects generally last for about 4 to 6 hours. It's important to understand that Viagra is not a cure for erectile dysfunction, nor does it increase libido. It simply helps facilitate the physical process of an erection when the conditions are right. It will not work if there is no sexual stimulation or if underlying psychological issues are not addressed.

Side effects and when to stop

Like all medications, Viagra can cause side effects. Most are mild and temporary. Common side effects include headache, flushing (reddening of the face), nasal congestion, indigestion, and visual disturbances (such as blurred vision or a blue tinge to your vision). These usually subside as the medication leaves your system.

You should stop taking Viagra and seek immediate medical attention if you experience:

• An erection lasting longer than 4 hours (priapism).
• Sudden vision loss in one or both eyes.
• Sudden decrease or loss of hearing.
• Symptoms of a heart attack, such as chest pain, shortness of breath, or dizziness.
• A severe allergic reaction (rash, hives, swelling of the face, lips, tongue, or throat).

Always discuss your full medical history with the prescribing doctor to understand all potential risks.
