Patanol (Olopatadine)

patanol

Patanol is a brand name for the medication known as olopatadine. It is an antihistamine eye drop used to relieve itching, redness, and other symptoms caused by allergies in the eyes. Allergic conjunctivitis is a common condition where the eyes become irritated due to exposure to allergens such as pollen, pet dander, or dust.

Olopatadine works by blocking the action of histamine, a chemical released by the body during an allergic reaction, which helps reduce the symptoms of eye allergies.

Patanol eye drops are typically prescribed for individuals with seasonal allergic conjunctivitis (hay fever) or perennial allergic conjunctivitis (year-round allergies). It is available in different strengths and formulations, so it is essential to follow your doctor's instructions on how to use it properly.

Uses

As mentioned earlier, Patanol is primarily used to treat allergic conjunctivitis, a condition where the eyes become irritated due to exposure to allergens. It is commonly prescribed for the following types of eye allergies:

  • Seasonal Allergic Conjunctivitis (Hay Fever): This occurs during specific seasons when pollen from trees, grasses, or weeds is present in the air.
  • Perennial Allergic Conjunctivitis: This type of eye allergy persists year-round and is usually triggered by allergens like pet dander, dust mites, mold spores, or other indoor allergens.

Patanol eye drops work as an antihistamine, which means they block the release of histamine, a chemical that triggers the allergic response. By reducing histamine's effects in the eyes, Patanol helps alleviate symptoms associated with eye allergies, such as:

  • Itching
  • Redness
  • Watering or tearing of the eyes
  • Swelling of the conjunctiva (the tissue lining the inside of the eyelids and covering the white part of the eye)

The medication is usually prescribed to be used for a short duration during allergy seasons or as needed for symptomatic relief.

Dosage

The dosage of Patanol eye drops can vary based on the severity of your eye allergies. It's essential to follow your doctor's instructions and the dosage information provided on the medication label. The following dosage guidelines are typical:

General instructions for using Patanol eye drops:

  • If you are using other eye drops or ointments, wait at least 5 minutes between applying each medication.
  • Replace the cap on the bottle after each use.

If you miss a dose, apply it as soon as you remember. However, if it is close to the time for your next scheduled dose, skip the missed dose and continue with your regular dosing schedule. Do not use extra drops to make up for a missed dose.
