Avoid combining Revatio with nitrates (like nitroglycerin) or other similar medications used to treat chest pain. This combination can cause a dangerous drop in blood pressure, leading to dizziness, fainting, or even more serious complications. Always inform your doctor of all medications you are taking, including over-the-counter drugs and supplements.
Specific Medications to Discuss with Your Doctor
Alpha-blockers: These drugs, often used for high blood pressure or enlarged prostate, can interact with Revatio, potentially causing a significant drop in blood pressure. Discuss your use of alpha-blockers such as tamsulosin or terazosin with your physician before starting Revatio.
CYP3A4 Inhibitors: Some medications inhibit the enzyme CYP3A4, which is involved in breaking down Revatio in your body. This can lead to higher levels of Revatio in your system, increasing the risk of side effects. Examples include ketoconazole, erythromycin, and grapefruit juice. Carefully review potential interactions with your doctor.
Other Important Considerations
Herbal remedies and supplements: Certain herbal supplements might also interact with Revatio. Always disclose their use to your doctor. Alcohol can intensify the side effects of Revatio. Limit or avoid alcohol consumption while taking this medication. Regularly monitor your blood pressure and report any unusual symptoms to your healthcare provider immediately.
