Are there any other precautions or warnings for this medication?
Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Breathing problems: People with asthma and certain other breathing problems should not take propranolol.
Congestive heart failure: People with congestive heart failure should not take propranolol.
Diabetes: The signs of low blood sugar may not be as noticeable when taking propranolol. People with diabetes who take insulin or other medications that work by reducing the sugar in the blood should be cautious and monitor blood sugar carefully while taking this medication.
Dizziness: Move slowly when moving from a lying down or sitting position to a standing position as dizziness may occur, especially when this medication is first being started.
Hyperthyroidism (high level of thyroid hormones): People with hyperthyroidism should be cautious while taking propranolol as it may reduce the symptoms of this condition giving a false impression of improvement. Stopping the medication suddenly could worsen this condition.
Severe allergies: People with allergies severe enough to cause anaphylaxis (a severe allergic reaction where swelling of the face, lips, and throat make it difficult to breathe) should talk to their doctor about what to do if they have an allergic reaction. Propranolol may make it more difficult to treat their allergic reaction with epinephrine.
Stopping medication: Propranolol should not be stopped suddenly by people who are taking it to treat angina. There have been reports of severe worsening of angina and of heart attack or abnormal heart rhythms occurring for people with angina pectoris who have stopped the medication abruptly.
Surgery: If you are scheduled for surgery, inform all doctors involved in your care that you take propranolol.
Pregnancy: Not enough information exists on the safe use of propranolol by pregnant women. Propranolol should be used during pregnancy only if the potential benefits justify the potential risks.
Breast-feeding: Propranolol passes into breast milk. Talk to your doctor about the risks and benefits of using this medication while breast-feeding.
Children: There is limited experience in the use of propranolol by children. Caution is advised with its use by this age group.
