question: Dear Doctor,I have a 18 yr old toddler. A few months back, she had been prescribed Sinarest AF for her cold symptoms and that had worked pretty well for her. She again has the same symptoms and I only have regular Sinarest Syrup. I wanted to ask if the Sinarest AF and Sinarest Syrup are the same group of drugs? Also what should be the dosage of Sinarest Syrup for 18months toddler (weight 28 lbs). Appreciate your help. Thanks.
