If you’re taking Singulair oral tablet, you’ll swallow it whole once per day. If you’re taking Singulair chewable tablet, you’ll chew and then swallow it once per day. You can take either of these two forms with or without food.
Children should swallow Singulair oral granules whole. Or they may take them as follows:
- dissolved in 1 teaspoon of baby formula or breast milk, which can be cold or room temperature
- mixed with a spoonful of soft foods (only applesauce, carrots, rice, or ice cream), which can be cold or room temperature
Be sure to give the full dose of the granules to your child within 15 minutes after opening the packet. Your child can take the granules with or without additional food.
Your doctor may advise that this medication be taken around the same time each day. This helps keep a consistent amount of the drug in the body. And that can help the drug work more effectively.
