The fix-AR Tablet is used to control allergy symptoms like frequent sneezing, a runny nose, and watery eyes. It may be taken for a longer period in some cases of chronic allergies, but only under a doctor's advice. Most people tolerate it well, though mild side effects such as headache, dizziness, or stomach upset can occur. If your allergy symptoms persist, it is best to consult a doctor to decide the right duration and treatment plan.
