Hytrin Oral Interactions

Your healthcare professionals (e.g., doctor or pharmacist) may already be aware of any possible drug interactions and may be monitoring you for it. Do not start, stop or change the dosage of any medicine before checking with them first.

Before using this medication, tell your doctor or pharmacist of all prescription and nonprescription/herbal products you may use, especially of:

• drugs for male erectile problems (e.g., sildenafil, tadalafil, vardenafil)
• medications for high blood pressure (e.g., verapamil)
• other alpha-blockers (e.g., alfuzosin, tamsulosin)
• sildenafil

If you are also taking sildenafil and your dose is more than 25 milligrams, you can reduce your risk of fainting by taking your doses of sildenafil and terazosin more than 4 hours apart. Consult your doctor or pharmacist if you have any questions.

Tell your doctor or pharmacist if you also take drugs that may lower blood pressure, cause drowsiness or urination problems such as:

• certain antihistamines (e.g., diphenhydramine)
• muscle relaxants (e.g., carisoprodol)
• narcotic pain relievers (e.g., codeine, morphine)
• psychiatric medicines (e.g., phenothiazines such as chlorpromazine, or tricyclic antidepressants such as amitriptyline)

Check the labels on all your medicines (e.g., cough-and-cold products, diet aids, NSAIDs for pain/fever reduction) because they may contain ingredients that could make you drowsy or dizzy, or increase your heart rate or blood pressure. Ask your pharmacist about the safe use of those products.

This document does not contain all possible interactions. Therefore, before using this product, tell your doctor or pharmacist of all the products you use. Keep a list of all your medications with you, and share the list with your doctor and pharmacist.
