I frequented the hospital as a kid because my eyes were constantly itchy. Because of that, I always had eye drops. Yours may be different and only require a one-off dosage or a regular one like mine. It all depends on the cause of your itchy eyes.

You may develop itchy eyes s a result of mild irritation or dry eyes. At the same time, it may stem from more severe issues like allergic conjunctivitis and blepharitis. The causes of your itchy eyes will determine whether or not you need an eyedrop and which eyedrop you’d need. 

In this article, we’ll highlight well-researched and medically approved eye drops you can use for itchy eyes. 

There are also very effective OTC eye drops, but it is best to use them only when your doctor or healthcare provider prescribes them!

Causes of Itchy Eyes

Before we look at the eye drops for itchy eyes, why itchy eyes in the first place? You might be wondering why you have itchy eyes, and here is why:

The eyes itch for several reasons, including allergies, dry eyes, conjunctivitis, eye strain, irritation, or even foreign objects. However, allergies are usually the general cause of itchy eyes. You could be allergic to dust and pollen or even sensitive to too much light.

When these allergens contact the surface of your eyes, histamines are released from the immune system cells.  These cells, called mast cells, trigger allergy symptoms.

Histamine, on the other hand, is a natural chemical produced by your body whenever you have an allergic reaction to something. Most times, this histamine released causes inflammation leading to disturbing eye issues like eye itching, red eyes, swollen eyes and sensitivity to light. 

Types of Eyedrops for Itchy Eyes

Saline Eye Drops

Saline eyedrops are mainly over-the-counter eyedrops and many people find relief from itchy eyes after using them. These eye drops, however, only contain sodium chloride and no genuine medication. They function by briefly flushing allergens from your eyes. They also provide much-needed moisture, which helps soothe dry, itchy eyes.

Saline eye drops are available in different varieties and name brands. When using, it is important to follow the directions provided at the rear of the product's container or your doctor’s directives.

Antihistamine Allergy Eye Drops

Antihistamine medications are available as eye drops and as oral medications. If you have itchy, watery eyes, antihistamine eye drops can make you feel better by obstructing the histamine produced when you have an allergic reaction to something.

Antihistamine medications work by instantly reducing your symptoms. But because the relief only lasts for a few hours, you might need to use it several times a day.

Your healthcare provider or pharmacist will tell you more about how to use them safely and effectively. 

Decongestant Eye Drops

Decongestant eyedrops are the best to help ease redness and brighten your eyes, but for a short time. You can get them as OTC medications without a prescription, but medical professionals do not advise usage if you have eye allergic reactions. 

If you have glaucoma, you should also stay away from decongestant eyedrops. 

It is not also advisable to use decongestant eyedrops for so long because they can make your itching worse with ‘rebound redness’. And when you finally stop, the inflammation and swelling may continue.

Multiple-action Eye Drops

Some eyedrops are a combination of various medications. These are called multiple-action or dual-action eyedrops. 

Antihistamine/decongestant combination eyedrops minimize:

  • eye itching
  • watery eyes, and 
  • soreness

While antihistamine/mast cell stabiliser combination eyedrops help to treat and also avoid:

  • eye itching
  • inflammation
  • tearing
  • burning

Recent eyedrops are particularly very useful for people with allergic conjunctivitis.

Mast Cell Stabiliser

Mast cell stabiliser eyedrops are a type of anti-inflammatory eyedrops and are among the latest kinds of eyedrops available today.

Mast cell stabiliser helps to avoid the release of histamine and other chemicals your body makes when reacting to an allergen. Their work is to prevent the symptoms of your eye allergy, which in most cases includes itching.

Unlike decongestant eyedrops, you can use these drops for more extended periods without side effects, especially if you wear contact lenses.

Anti-inflammatory Allergy Eye Drops

Anti-inflammatory eye drops fall under two categories:

  • Nonsteroidal anti-inflammatory drugs (NSAIDs).
  • Corticosteroids.

NSAID eyedrops affect certain nerve endings and change how your body makes you feel itchy. On the other hand, Corticosteroid eyedrops are for treating severe and long-term eye allergy symptoms.

Just like decongestant eyedrops, doctors do not recommend long-lasting use unless your case is severe, as it will only lead to side effects. 

However, when using corticosteroid eyedrops, be sure to check in with your opthalmologist regularly. You might also want to consider that using these eyedrops puts you at risk of having: 

  • Cataracts
  • Eye infection
  • Glaucoma
  • Increased pressure in the eye
