I just went through a horrible experience with this. My daughter had pneumonia and refused her antibiotic and even with holding her down, she would spit it out. I tasted her first antibiotic and it did have a horrible chewed up asprin like taste to it. I had to take her to the emergency room because of a high fever and not being able to get meds in her and they switched antibiotics to something that tasted better but my daughter still would not take it. I eventually got her to take it by mixing it in strawberry yogurt when she wasn't looking and letting her put mini m&m's in it. If she has to take another antibiotic soon I am not going to even let her know there is medicine in the house, taste it myself to see what it tastes like, and then try to hide it is something. The doctor recommended chocolate pudding but if the medicine if fruity and you mix it in pudding, they will detect the difference in taste. Same thing with things like milk. Your child knows what milk tastes like so they will know it tastes different but maybe you could cover the taste by adding strawberry syrup. Depending on the taste and consistancy, I read that OJ, cranberry juice, yogurt, pudding and applesauce are good at masking flavors. Good luck in the future.
