Insomnia and cozaar (losartan): You need to speak to the physician (P) who ordered the cozaar (losartan) (C) for you. C is from an arb which have very few side effects. If you are having insomnia (I) from C, ask your P to order you either another arb or switch you to another BP medicine, or arb, to see if it gets better. Good luck
