What Is Patanol Prescribed For?

Patanol® (olopatadine ophthalmic solution) is a prescription eyedrop approved for treating eye allergy symptoms in adults and children as young as three years old. Some symptoms of eye allergies may include:
  • A red or pink eye
  • Itchy eyes
  • Burning or stinging of the eyes
  • Watery eyes
  • Puffy eyes.
Patanol belongs to a group of allergy medications known as antihistamines. Specifically, it is an H1 receptor antagonist. This means it blocks a specific type of histamine receptor in the body (known as H1 receptors). Because allergic reactions are partly caused by the release of histamine from certain cells in the body, Patanol is prescribed for relieving or preventing allergy symptoms.
In addition to blocking histamine receptors, Patanol seems to decrease the release of histamine from the cells in the body. This may also help prevent or relieve symptoms of eye allergies.
