Viagra Eligibility Requirements and Safety Considerations
Age Requirements for Viagra
Viagra is approved for adult men aged 18 and over who experience erectile dysfunction. There is no upper age limit for Viagra use, though older patients may require careful assessment due to increased likelihood of underlying health conditions or medications that could interact with sildenafil. Men over 65 may be started on a lower dose due to slower metabolism of the medication.
Who Can Take Viagra Safely
Viagra may be suitable for men who have difficulty achieving or maintaining an erection sufficient for sexual activity. Candidates must be physically healthy enough for sexual activity and have no contraindications to sildenafil use. The medication works by increasing blood flow to the penis during sexual arousal, making it easier to achieve and maintain an erection.
At EverydayMeds, patients can choose between branded Viagra and generic sildenafil during checkout. Both contain the same active ingredient and work identically, with sildenafil offering a more cost-effective alternative whilst maintaining the same efficacy and safety profile.
Medical Conditions That May Prevent Viagra Use
Several health conditions may make Viagra unsuitable or require special precautions. Men with severe heart disease, recent heart attack or stroke (within six months), or very low blood pressure should not use Viagra. Those with severe liver problems may require dose adjustments or alternative treatments.
Certain eye conditions, particularly hereditary degenerative retinal disorders, may also contraindicate Viagra use. Men with anatomical deformation of the penis or conditions predisposing to prolonged erections require careful evaluation before treatment.
Medication Interactions and Contraindications
The most serious contraindication involves nitrate medications, commonly prescribed for chest pain. Combining Viagra with nitrates can cause dangerous drops in blood pressure. This includes GTN spray, isosorbide tablets, and recreational substances containing nitrites.
Alpha-blockers for prostate problems or high blood pressure may require dose adjustments when used with Viagra. Some HIV medications, antifungal treatments, and antibiotics can also interact with sildenafil, requiring careful monitoring or dose modifications.
Clinical Assessment Process
Before prescribing Viagra, healthcare providers conduct a comprehensive assessment covering medical history, current medications, and cardiovascular health. This evaluation helps ensure safe use and identifies any potential contraindications or required precautions.
The assessment includes questions about heart problems, blood pressure, liver function, and current medications. Patients must provide honest, complete information to ensure safe prescribing. EverydayMeds' UK-licensed prescribers review each consultation carefully before approving treatment.
Starting Treatment Safely
Most men begin with a 50mg dose of Viagra or sildenafil, taken approximately one hour before sexual activity. The dose may be adjusted based on effectiveness and any side effects experienced. Only one dose should be taken within 24 hours, and the medication should be used as needed rather than daily.
Patients should be aware that Viagra requires sexual stimulation to work effectively. The medication does not cause automatic erections but enhances the natural response to sexual arousal. Effects typically last four to six hours, though this varies between individuals.
