Tamiflu
"Our pharmacy mixed Tamiful in-house for our five-month-old.  As soon as the medicine was in her mouth, her stomach would convulse and she would completely empty her stomach, whether she took it alone or with food. We were told by the doctor there was no other option other than to discontinue use. Two days later, we were back at the pharmacy to fill the same prescription for her 4-year-old brother. The commercial preparation was available then. I talked to the pharmacist about the baby's reaction to Tamiflu, and she said the sugar base from the in-house mix was the likely culprit. We refilled the baby's prescription with the commercial preparation, and she tolerated it just fine. I'm so grateful, because she really needed the medicines!"
