Hi,

Thank you for posting your query.

Propranolol is a safe and effective medicine for prevention of migraine headaches.

I wish to reassure you that the darkening of knuckles is not related to propranolol. So, if the medicine is helping you with migraines, please continue it and there is no need to stop it.

In my practice, the most common reason for darkening of knuckes is blood test.

If the symptom is troubling you or if it increases in severity, you may see a dermatologist.

Best wishes,
