I currently take 100 mg of Losartin Pot. I have had issues with the drug since I have been taking (March 2013) but thought my body would adjust. Within the last 2 months I have started having severe hair loss, sweating, cough, runny nose, hoarseness, sweating and a really bad persistent headache. Most recent headache I have had for a week. Took pill tonight and what even made me check side effects is that inside of mouth started swelling. Not having problems breathing.
