I have been taking lexapro (10 Mg.) since the beginning of April and also around that tie began taking Lisinipril (10 Mg.). About 4 weeks ago I begn having symptoms of throat scratchiness and post nasal drip with clearing of the throat and my primary just this week switched me to Losartan (50 Mg.). My mood changed a bit just a few hours after taking the new med and I have had a slight headache (just today). This is the third day I am on the Losartan. Is there any issues with the lexapro and losartan and is the slight headache today due to a side effect? How long can I expect to have these symptoms before they go away?
