Patanol is a type of medicated eye drop that is applied directly to the eyes to help with the symptoms of allergies. When a patient has seasonal allergies, it can cause a lot of itchiness of the eyes as well as eye-watering and redness. This medication is a type of antihistamine that helps to reduce the chemicals in the body that are causing this response.

When a patient comes into contact with a seasonal allergen, there are chemicals called histamines that are released into the body. These histamines are what cause the symptoms of allergies. When Patanol is applied to the eyes, it lowers these histamines and reduces the type of response that the body has to the allergen. They may also be prescribed for other eye issues as directed by your doctor.

Generally, patients have an eye exam before this medication is prescribed. This is to rule out other causes for the allergy symptoms and to check for serious eye diseases and conditions. If it’s determined that it’s histamines that are causing the problem, Patanol may be the right medication to take. It’s generally not prescribed to help with the eye irritation that can come from wearing contacts.

Patanol Precautions and Warnings

If you have an eye infection, you may not be able to use this medication until it’s cleared up. They also shouldn’t be used when you have contact lenses in. The eye drops can be applied before you put contacts in. Then, wait 10 minutes or longer before putting them in.

The active ingredient in Patanol is olopatadine. If you have an allergy to this ingredient, don’t use these eye drops. If you’re allergic to it, you may have wheezing, a hard time breathing, shortness of breath, hives or itchy skin, or swelling in your mouth or on your face.

If you have an eye infection, make sure your doctor knows about it. It’s also important to tell them if you are pregnant or breastfeeding. There isn’t much known about the effects it can have during pregnancy or breastfeeding, and you may not want to take it during this time. The medication shouldn’t be used on anyone who is under two years old.

Check the bottle before using this medication to make sure that it’s still sealed and hasn’t been tampered with. If the seal is broken, don’t take the medication. You should also notice the expiration date on it, and don’t take this medication after that date. After the expiration date has passed, the medication may not work anymore.

When you handle the bottle, don’t allow the tip of the dropper to touch anything. It shouldn’t even touch your hands or eyes. Anything that touches the tip of the dropper can cause the bottle to be contaminated. This can mean getting an eye infection. Some infections can lead to eye damage and vision loss. If you notice that the liquid in the bottle has particles inside it or has changed colors, don’t use it. The bottle is likely contaminated.

Don’t use this medication if you try it and get any of these symptoms from using it:

  • Serious redness
  • Burning
  • Crusting
  • Swelling
  • Drainage
  • Stinging
  • Other irritation

Patanol Side Effects

If you take Patanol Eye Drops and start to feel unwell, let your doctor know. Like all medications, there may be side effects that the doctor needs to know about. Most people don’t have any side effects from it, but they are possible.

It’s also possible to have an allergic reaction to this medication, and this can be serious. It’s important to get emergency care immediately if you get swelling in your face, feet, or hands, you have difficulty breathing or wheezing, or you get hives. These side effects aren’t common, but it’s important to watch for them just in case they happen.

It’s important not to take Patanol Eye Drops any more often than is recommended by your doctor. If you use it more often, it can make the side effects worse and more likely. Using it too often also won’t mean faster relief from the allergy symptoms.

The most common side effects are typically mild and go away after the patient has been using the medication for a while. These effects include:

  • Headache
  • Dizziness
  • Dry nose or mouth
  • Weakness
  • Taste changes
  • Nausea
  • Skin rash

What does Patanol do?

It’s an antihistamine that’s applied to the eyes to help relieve eye allergy symptoms. It’s fast-acting and is taken daily.

How does it work?

It lowers the amount of histamines that the patient’s body releases when it comes into contact with a seasonal allergen like pollen. This reduces the symptoms of allergies in the eyes.

How do you apply it?

First, wash your hands and dry them. Make sure the dropper tip of the bottle doesn’t touch your hands or anything else to avoid contamination. If you have contact lenses in, take them out before you apply the drug. Wait 10 minutes to put them back in again after you’ve applied the medication. Tilt back your head and look up. Take the lower eyelid between your fingers and gently pull it down. This makes a pouch where you can drop the eye drops. Place one in each eye. Then close your eyes and keep them closed for a minute or two. It helps to press gently on the corners of your eyes with one finger during that one to two minutes. Put the cap back onto the dropper to keep it clean.

Is Pataday the same thing as Patanol?

Yes, these are the same drug. Patanol was the prescription version, and Pataday is the OTC version. The 0.1% version is the same formulation as the prescription strength. There is also a stronger Pataday strength of 0.7%.

Can I take an eye ointment along with this medication?

Yes. If you also have an eye ointment to apply, apply the Pataday first and wait at least five minutes for the medication to have plenty of contact with the eye. After five minutes or more, you can apply the eye ointment.

Do I have to take it at the same time each day?

This is a helpful way to remember to take the medication. It also helps to keep the level of the medication in your eyes steady. However, this isn’t required. As long as there are at least six to eight hours between doses of the lower strength and 24 hours since the last extra strength dose, you can take the next dose as needed.

Can I get a generic of this medication?

Yes, there are many generic brands that offer this medication in two different strengths. Many stores have their own brand of this medication.

 Can I take this medication for an eye infection?

No. This isn’t an antibiotic that would fight a bacterial infection in the eye. It’s an antihistamine that helps prevent eye allergy symptoms. A doctor would need to prescribe an antibiotic drop if you have an eye infection.

Can I drive after using it?

For some patients, these eye drops will cause blurry vision for a few minutes. You’ll need to wait until this blurriness clears before driving or operating other heavy machinery.
