My sis took monit 2.6 mg 20 tablets an year before and last 2 months before she took propranolol 180 mg as overdose.in both the situation she had low bp, headache and giddiness. She recovered with in one week with rest and hydration. Now since 15 days she is having low blood pressure 90/60,80/60,90/50 and taking oral fluids and iv fluids and still the same bp. Is there any concern to worry? Can it be related to medication long term effects or any other matter of concern please help.
