Can I take more than one allergy pill a day, even if the box says to only take one?

It is not recommended to take more than one allergy pill per day, even if it is indicated to take only one on the box. If you are experiencing strong symptoms in the evening, it may be helpful to combine your current medication with another allergy medication like Benadryl for temporary relief. Additionally, adding a nasal cortisone spray like Flonase Allergies may help better control your symptoms. Combining an antihistamine with a nasal cortisone spray is often recommended to improve symptom management.
