Propranolol is a beta-blocker. Beta-blockers affect the heart and circulation (blood flow through arteries and veins).

How should I take hydrochlorothiazide and propranolol?
Follow all directions on your prescription label. Your doctor may occasionally change your dose to make sure you get the best results. Do not use this medicine in larger or smaller amounts or for longer than recommended.
You may have very low blood pressure while taking this medicine. Call your doctor if you are sick with vomiting or diarrhea, or if you are sweating more than usual. Prolonged illness can lead to a serious electrolyte imbalance, making it dangerous for you to use hydrochlorothiazide and propranolol.
Your blood pressure will need to be checked often. Your blood and urine may both be tested if you have been vomiting or are dehydrated.
If you are diabetic, check your blood sugar carefully. Taking propranolol may make it harder for you to tell when you have low blood sugar. Your insulin or diabetes medication needs may change while you are taking hydrochlorothiazide and propranolol. Do not change your medication dose or schedule without your doctor's advice.
If you need surgery or medical tests, tell the doctor ahead of time that you are taking medication that contains hydrochlorothiazide. You may need to stop using the medicine for a short time.
Do not skip doses or stop using propranolol suddenly. Stopping suddenly may make your condition worse. Follow your doctor's instructions about tapering your dose.
Keep using this medicine as directed, even if you feel well. High blood pressure often has no symptoms. You may need to use blood pressure medicine for the rest of your life.
Store at room temperature, away from heat and moisture. Do not freeze. Keep the bottle tightly closed when not in use.
What happens if I miss a dose?
Take the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not take extra medicine to make up the missed dose.
What happens if I overdose?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.
Overdose symptoms may include slow heartbeats, trouble breathing, or fainting.
What should I avoid while taking hydrochlorothiazide and propranolol?
Avoid drinking alcohol. It may increase your blood levels of propranolol.
Ask your doctor before using an antacid, and use only the type your doctor recommends. Some antacids can make it harder for your body to absorb hydrochlorothiazide and propranolol.
Avoid getting up too fast from a sitting or lying position, or you may feel dizzy. Get up slowly and steady yourself to prevent a fall.
