Levitra 20mg, like other medications, interacts with certain substances. Avoid combining it with nitrates (found in some heart medications) due to a dangerous drop in blood pressure. This combination can be life-threatening. Also, avoid using Levitra with strong CYP3A4 inhibitors like ketoconazole or erythromycin, as they increase Levitra’s concentration in the blood, potentially leading to side effects.
Specific Medication Interactions
Grapefruit juice significantly raises Levitra levels; avoid it while using this medication. Similarly, be cautious when combining Levitra with alpha-blockers (used for high blood pressure or enlarged prostate), as this can cause dizziness or fainting. Always inform your doctor about all medications, including over-the-counter drugs and supplements, you are taking before starting Levitra 20mg.
Contraindications
Levitra is contraindicated for individuals with a history of heart attack, stroke, or uncontrolled high blood pressure. Men with retinitis pigmentosa (a rare eye disease) should also avoid Levitra due to potential vision problems. If you experience sudden vision loss, stop using Levitra and seek immediate medical attention. Consult your doctor to determine if Levitra is safe for you, considering your medical history and current medications.
