Yes: OTC allergy meds are generally very effective.

No: Over-the-counter allergy medicines are helpful for nasal and Eye symptoms due to allergies. Shortness of breath is more concerning symptom that can I have many causes. Over-the-counter medications are not going to be sufficient for this. The cause of the symptoms needs to be identified so the right treatment can be recommended.
