How to use propranolol
Propranolol comes as oral tablets (formerly sold as Inderal), extended-release capsules (brand name Innopran XL), or a liquid solution (formerly sold as Propranolol HCl Intensol). Some specialized liquid formulations, such as Hemangeol, are used for specific conditions, like infantile hemangioma. Dosage forms depend on your condition and your doctor’s guidance.
Adults with high blood pressure often start with 80 mg once daily in extended-release form, which can be increased to 120-160 mg if needed. Immediate-release tablets may be split into multiple doses, while extended-release capsules are usually taken once a day.
Take propranolol exactly as prescribed and at the same time each day. Don’t exceed your dose or stop suddenly without consulting your doctor. The medication can slow your heart rate and lower blood pressure, so watch for dizziness, fainting, or unusually slow heartbeat.
Before starting propranolol, tell your healthcare provider about any medical conditions, including heart problems, asthma, lung disease, kidney or liver issues, diabetes, or hyperthyroidism. Mention all medications and dietary supplements you take, especially antacids, NSAIDs, blood pressure drugs, heart rhythm medications, warfarin, and antidepressants.
Propranolol isn’t suitable for everyone. People with asthma, certain heart conditions, very low blood pressure, or a known allergy to the medication should avoid it. If you are pregnant, planning to become pregnant, or breastfeeding, discuss risks and benefits with your doctor.
