Does Armodafinil Interact with Propranolol?
CDI records a moderate classification for Armodafinil and Propranolol. The stored summary is: Elimination of propranolol may be prolonged by armodafinil via inhibition of metabolic enzymes, resulting in higher systemic exposure. Dose reduction may be required. The mechanism involves inhibition of cyp2c19 metabolic enzymes. Patients taking both medications should consult their healthcare provider before starting, stopping, or changing the dosage of either drug. This record was extracted from drug labeling through openFDA. NIH/NLM RxNorm is used for drug identities. The summary and severity classification are CDI's processed information, not a verbatim source quotation. Product, route, and patient circumstances matter.

- Ask whether any dosage adjustments are needed
- Never stop or change either medication without first consulting your healthcare provider
