Patanol

Patanol is used for relieving symptoms of eye allergies. By blocking a specific type of histamine receptor in the body, the medication can help relieve or prevent allergy symptoms. It comes in the form of an eyedrop that is placed in each eye twice a day. Most people have no problems, but side effects can include headaches, blurred vision, and burning or stinging in the eye.

What Is Patanol?

Patanol® (olopatadine ophthalmic solution) is a prescription eyedrop used for the treatment of signs and symptoms of eye allergies (known medically as allergic conjunctivitis). Allergic conjunctivitis is a common cause of pink eye.

How Does Patanol Work?

Patanol belongs to a group of allergy medications known as antihistamines.
 Specifically, it is an H1 receptor antagonist. This means that 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, this medication can help relieve or prevent 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 the symptoms of eye allergies.
 

When and How to Take It

Some general considerations for those taking Patanol include the following:
 
  • This medication comes in the form of an eyedrop. It is usually used in each eye twice a day, with six or eight hours between the two doses.
     
  • In order to prevent contamination of the drops, do not touch the tip of the dropper to any surface, including the surface of the eye.
     
  • If you wear contact lenses, you must remove them to use the drops. In order to prevent the lens from absorbing some of the ingredients in the medication, make sure to wait at least 10 minutes after using the drops before reinserting the lens. Do not wear your contact lenses if your eye is still red.
     
  • For Patanol to work properly, it must be taken as directed.
