45 yr female, 225 lb, hypertension with chronic kidney disease III, and constant migraines.  Quality of life is nil, and doctors have not been able to offer relief, so I am ready to stop the pain myself.  I have taken 40 10 mg Norvasc pills this morning.  Without intervention, is this a fatal dosage?
Hi, Thanks for writing in. Norvasc 10 mg is amlodipine and used in treatment of blood pressure and heart related disorders. This is not a pain medication and I suggest you discuss your pain in detail with your doctors, friends and family and the need to take higher pain relievers. Your condition is understandable, but it is important that you continue to live and forget about ending your life in this manner. I am sure there are a lot of friends and relative who are there to support you at all times and help you out with your pain. It would appear that the lethal level of amlodipine is in the range of 40 milligrams per kilogram. Adults taking up to 250 milligrams have remained asymptomatic. Survival following a 560 milligram overdose has been reported. So if you have taken 40 pills of 10 mg then most likely you will survive, and please seek immediate medical attention.
