Below are dose recommendations for several common over-the-counter products.  All doses are determined by weight, not age. If you have any questions as to the correct dosage, don’t hesitate to give us a call at 802-251-8626. Make sure you do not combine medicines that contain the same components (Tylenol & Feverall, for example, both have acetaminophen). This is easiest if you minimize products with multiple active ingredients.  Also, do not give medicines to infants less than 2 months without speaking to a doctor.
