How long does it take for propranolol to start working?
A doctor has provided 1 answer
Generally in 1 day: Propranolol comes in short-acting & extended release (XR) forms. The short-acting form works in about 1 hr to lower BP & heart rate, but wears off in about 4-6 hrs depending on individual metabolism (which is why it is dosed 3-4 times per day or more). The long-acting form starts working in about 2-3 hrs, but lasts 18-24 hrs. U shd know in 1 day or so if the dose is working to lower HR or BP.
