My mother has extreme hypertension and her doctor has her taking 40mg lisinopril,50 mg spironolactone, 10mg amlodipine and 100 mg atenolol. She is also on a NSAID called indomethacin 25mg. I have read that NSAID, combined with certain antihypertension drugs is very dangerous. Is she being over medicated? Is this combination of drugs safe?
