Do not stop using this drug without first consulting your doctor. Your condition may become worse when the drug is suddenly stopped, especially if you have chest pain (angina) or heart disease (e.g., coronary artery disease, ischemic heart disease, high blood pressure). If your doctor decides you should no longer use this drug, you must gradually decrease your dose according to your doctor's instructions.
When gradually stopping this medication, it is recommended that you temporarily limit physical activity to decrease strain on the heart. Seek immediate medical attention if you develop: worsening chest pain, tightness/pressure in the chest, chest pain spreading to the jaw/neck/arm, unusual sweating, trouble breathing, or fast/irregular heartbeat.Who should not take propranolol-hydrochlorothiazide?
This product contains 2 medications. Propranolol is a beta blocker that works by blocking certain natural chemicals in your body (such as epinephrine) that affect the heart and blood vessels. This effect reduces heart rate, blood pressure, and strain on the heart. Hydrochlorothiazide is called a "water pill" (diuretic) and causes your body to get rid of extra salt and water. This effect may increase the amount of urine you make when you first start the medication. It also helps to relax the blood vessels so that blood can flow through the body more easily.
These medications are used together when 1 drug is not controlling your blood pressure. Your doctor should direct you to start taking the individual medications first, and then switch you over to this combination product if this is the best dose combination for you.

This drug may make you dizzy or cause blurred vision. Do not drive, use machinery, or do any activity that requires alertness or clear vision until you are sure you can perform such activities safely. Limit alcoholic beverages.
To reduce the risk of dizziness and lightheadedness, get up slowly when rising from a sitting or lying position. Significant loss of body water from too much sweating, vomiting, or diarrhea can also lower your blood pressure and worsen dizziness. Drink plenty of fluids to prevent these effects and dehydration. If you are on restricted fluid intake, consult your doctor for further instructions. Contact your doctor if you are unable to drink fluids or if you have persistent diarrhea/vomiting.
This drug may reduce the potassium levels in your blood. Ask your doctor about increasing the amount of potassium in your diet (e.g., bananas, orange juice) or about using a salt substitute containing potassium. A potassium supplement may be prescribed by your doctor.

Other symptoms of a low blood sugar level, such as dizziness and sweating, are unaffected by this drug. This product also may make it harder to control your blood sugar levels. Check your blood sugar levels regularly as directed by your doctor. Tell your doctor right away if you have symptoms of high blood sugar such as increased thirst, hunger, and urination. Your anti-diabetic medication or diet may need to be adjusted.
