The recommended starting Inderal dosage for treating high blood pressure or essential tremor is 40 mg twice a day. When treating angina, the dose ranges from 80 mg to 320 mg per day. People with atrial fibrillation may be prescribed 10 mg to 30 mg three or four times a day. Factors that can affect Inderal dosage include how you respond to the drug, other medications you are taking, and other medical conditions you have.
The dose of Inderal® (propranolol hydrochloride) that your healthcare provider prescribes will vary, depending on a number of factors, including:
- Your age
- The medical condition you are being treated for
- Other medical conditions you may have
- Other medications you may be currently taking
- How you respond to Inderal.
As always, do not adjust your Inderal dose unless your healthcare provider specifically instructs you to do so.
The recommended starting dosage of Inderal for people with high blood pressure (hypertension) is 40 mg twice a day. After a couple of weeks, based on the blood pressure response and/or Inderal side effects, the dosage may be increased or decreased. Your healthcare provider may also add a diuretic (a "water pill") or another blood pressure medication if your blood pressure is not controlled by Inderal alone.
Some people may need to take up to 640 mg a day (320 mg twice a day) in order to lower blood pressure enough. However, the usual dose for most people is somewhere between 120 mg and 240 mg a day, taken as two smaller doses (60 mg to 120 mg twice a day).
While twice-a-day dosing is adequate for most people, the effects of the medication may wear off too soon in some individuals (causing high blood pressure at the end of the dosing interval). In such situations, your healthcare provider may recommend that you take Inderal three times a day.
