Propranolol
HeartAlso known as Inderal LA
Propranolol is a beta blocker that calms adrenaline's effects on your whole body. Doctors prescribe it for blood pressure and heart rhythm problems, but also to prevent migraines, steady a tremor, and quiet performance anxiety — the pounding heart and shaky hands before a big moment. Whatever you take it for, the heart-safety rules still apply.
How to take it
When
Timing depends on why you take it — some forms are a few times a day, Inderal LA is once daily. Follow your prescription exactly.
Food
Be consistent: take it the same way every time, with food or without, so your levels stay steady.
Avoid
If you take it every day, never stop suddenly — that can trigger chest pain or a heart attack. Taper with your doctor.
Good to know
If you have diabetes, it can hide the racing heart that warns you of low blood sugar. Tell your doctor if you have asthma — it can tighten airways.
Missed a dose?
Take it as soon as you remember, unless your next dose is coming up soon — then skip the missed one. Never double up.
