Critical Safety Information for Viagra Users

Dangerous Drug Combinations to Avoid

The most critical safety consideration when taking Viagra or sildenafil is avoiding dangerous drug interactions. Never combine with nitrate medications including GTN spray, isosorbide mononitrate, or nicorandil used for angina. This combination can cause a potentially life-threatening drop in blood pressure. Similarly, avoid riociguat (used for pulmonary hypertension) and recreational drugs containing nitrites or "poppers".

Medical Conditions That Rule Out Treatment

Viagra is not suitable for men with certain health conditions. These include severe heart disease, recent heart attack or stroke within six months, severe liver problems, or very low blood pressure. Men taking alpha-blockers for prostate problems may need dose adjustments or should avoid sildenafil entirely. Those with hereditary eye conditions affecting the retina should also avoid this medication.

Timing and Dosage Considerations

Take Viagra approximately 30-60 minutes before sexual activity, but never more than once daily. The standard starting dose is 50mg, which may be adjusted to 25mg or 100mg based on effectiveness and side effects. EverydayMeds offers both Viagra (branded) and generic sildenafil options, allowing patients to choose based on preference and budget during the online consultation process.

Lifestyle Factors That Reduce Effectiveness

Large or fatty meals can significantly delay Viagra's onset of action, sometimes by several hours. Excessive alcohol consumption reduces effectiveness and increases the risk of side effects like dizziness and low blood pressure. While moderate alcohol is generally acceptable, limiting intake optimises treatment success.

When to Seek Medical Advice

Contact a healthcare provider immediately if you experience chest pain, severe dizziness, or an erection lasting more than four hours. Regular monitoring may be needed for men with cardiovascular conditions, diabetes, or those taking multiple medications. EverydayMeds' online clinical assessment helps identify potential contraindications before treatment begins.
