Symptoms: low mood,dizzy,more tired than usual,crying for no reason

Doctor: Thank you for your question. Propranolol is a beta blocking class of cardiac medication. There has been reports that th is medication can cause depressive episodes, however studies have been inconclusive. It is therefore hard to definitively suggest that your depression could be caused by this medication. It is important that you also have an under-active thyroid as well as firbromyalgia and these are both associated with depressive mood manifestations. It is important that you monitor the way you are feeling, however we do not suggest you abruptly stopping your medication without consulting your cardiologist. Should your depression worsen, we suggest that you consult your physician and have your thyroid re-examined to see if your medication is enough to therapeutically manage your condition.Thank you for choosing
