Inderal LA (Propranolol Hcl)

Do’s

• Take Inderal LA by mouth as directed by your healthcare provider, usually once daily. Swallow the capsules whole.
• The dosage is based on your medical condition and response to treatment. It may take 1 to 2 weeks before you get the full benefit of this medication.

• If you also take certain drugs to lower your cholesterol (bile acid-binding resins such as cholestyramine or colestipol), take Inderal LA at least 1 hour before or at least 4 hours after these medications.

Don’ts
