Be aware that symptoms of low blood sugar may be hidden by your beta-blockers, except for sweating.Your healthcare professionals (e.g. doctor or pharmacist) may already be aware of this interaction and may be monitoring you for it. Do not start, stop, or change the dosage of any medicine before checking with them first.
