I am having heart palpitations with and without a cough for about five weeks now. This occurs daily, sometimes throughout the day. For approximately 45 days prior to this starting I started taking prescription Integra F capsules for anemia. I also take Lexapro (10 mg) and I was taking a childrens multiple chewable viatimin. Around the 45 day mark, I not only had the heart palpitations and cough, but was also short of breath, dizzy, and felt confused. I found information indicating never to take the Integra F capsule with any type of multiple viatimin as it could cause viatimin overdose. I immediately stopped taking the children viatimin; however, after five weeks I am still getting the heart palpitations and cough. I feel like I brought this on myself taking the two together, but do not know that for sure and do not want to ignore it.
