Vilitra 20 contains Vardenafil, which is a medication used for erectile dysfunction. Like all medications in this class, it can interact with certain health conditions and other medications, so there are specific situations where a doctor should definitely be consulted before use: 1. Heart and Blood Pressure Conditions Heart disease: History of heart attack, stroke, or severe heart failure. Chest pain (angina): Especially if it occurs during ****** activity. Low or high blood pressure: Uncontrolled hypertension or hypotension can be risky. Use of nitrates: Vilitra 20 (like nitroglycerin) for chest pain cannot be taken with Vardenafil, as it can cause a dangerous drop in blood pressure. 2. Liver or Kidney Problems Severe liver impairment or kidney failure may require dosage adjustment or may make the drug unsafe. 3. Eye Disorders Retinitis pigmentosa or any history of sudden vision loss. Caution if there’s a risk of NAION (sudden optic nerve damage). 4. Other Medications Drugs for HIV, antifungals, antibiotics, or other ED medications may interact. Always check with a doctor if you take alpha-blockers for prostate issues or blood pressure medications, as interactions may cause dizziness or low blood pressure. 5. Allergies or Side Effects History of allergic reaction to Vardenafil or similar medications (like Sildenafil or Tadalafil). 6. Other Health Considerations Stroke, severe dehydration, or bleeding disorders may require caution. Men with anatomical penile deformities (like Peyronie’s disease) should be evaluated before use.  A doctor should be consulted before using Vilitra 20 if you have heart disease, blood pressure issues, liver/kidney problems, eye disorders, are taking certain medications, or have other significant health conditions. If you want, I can make a simple checklist you can take to a doctor to see if Vilitra 20 is safe for you—this makes it much easier to discuss.
