Naproxen syrup, including the 125 mg formulation, often has a naturally bitter taste due to the active ingredient. This bitterness can be unpleasant, especially for children or those sensitive to taste. To improve palatability, some manufacturers add flavoring agents to the syrup, but the degree of flavor masking varies by brand.

If you find the taste of naproxen syrup unpleasant, you can ask your pharmacist or doctor about flavored alternatives or formulations that might be more palatable. Sometimes, compounded versions with added sweeteners and flavors can be prepared by specialized pharmacies.

Always ensure that any alternative formulation is appropriate for your or your child's age and medical condition, and follow dosing instructions carefully. If taste is a significant barrier to medication adherence, discussing this with your doctor can help find the best solution for you.
