The tiny red spots you noticed that fade or disappear when pressed (called blanching) are generally reassuring, as they often point to a mild, temporary skin reaction rather than anything serious. While it is possible to have a mild reaction to Allegra-M (fexofenadine and montelukast), it is relatively uncommon. Please monitor the spots to see if they spread or if you develop other symptoms like itching, swelling, or difficulty breathing. If you feel unwell or if the spots persist, it's best to stop the medication and consult your doctor or pediatrician for a quick check.
