i need to know if verapamil or diovan can cause photosensitivity. every summer my spouse breaks out and its getting worse by the year. anytime he spend outside just doing regular things such as mowing the lawn or even just being outside with his shirt on. this rash started mostly on his back but not its getting on his arms and even spots on his legs. it is raised and dry at first we thought it was from our pool. but as time has gone on every year come summer heat it get worse.
