Do you sometimes wake up in the morning and your eyes feel red, itchy, or like there's something inside? Or do you just tear up? These can often be symptoms of an eye allergy. This can be really annoying. So today, let's talk about the different types of eyedrops that can be used for this allergy condition, how they work, and what we need to be careful about when using them.
Why do our eyes get allergies like this?
Simply put, this is an unwanted reaction of our body's immune system. When something that is normally harmless to us, for example a speck of dust, gets into our eyes, our body thinks it is a big enemy and starts to fight it. As a result of this fight, symptoms such as redness, itching, and swelling of the eyes appear.
There are several main causes of eye allergies:
- Pollen from flowers: These can float in the air and enter the eyes, especially during windy times.
- Household dust: Tiny larvae (dust mites) in dust are a major cause.
- Pet dander and skin: The dander and skin of animals like dogs and cats can cause allergies.
- Some medications and even contact lenses can cause allergies in some people.
Try these simple things before putting in an eyedrop
Before you go to your doctor, there are a few things you can try at home that may provide some relief.
- Using Artificial Tears: These drops, which can be purchased at pharmacies, help to rinse the eye, remove allergens, and moisturize the eye.
- Cold compresses on the eyes: Soak a clean cloth in ice water, close your eyes, and hold it over them for a few minutes. This will greatly reduce itching and inflammation .
- Stay away from allergens: Stay in an environment with as little dust as possible, keep windows closed, and wear sunglasses if you go outside.
If these simple things cannot control it, then we should consider eyedrops. But it is wiser to consult a doctor before taking medication on your own.
How do you choose the right eyedrop for you?
"Allergy Eyedrops" are not all the same. There are many types. Some are just for itching, others just for redness. Some provide quick relief, while others provide long-term allergy control. The type that's right for you will depend on the nature and severity of your symptoms.
There are several main types of eyedrops. Let's take a look at them.
| Eyedrop Type | Main Action |
|---|---|
| Antihistamine Eyedrops | Quickly reduces itchy, watery, and red eyes. |
| Anti-inflammatory Eyedrops | Controls severe symptoms like inflammation and swelling. |
| Decongestant Eyedrops | Temporarily reduces eye redness. |
| Mast Cell Stabilizers | Prevents the allergic reaction from occurring (preventive action). |
| Multiple-Action Eyedrops | The functionality of more than one of the above types is combined together. |
Antihistamine Eyedrops: Quick Relief!
When our eyes are exposed to an allergen, the body releases a chemical called 'Histamine' . This is what causes itching and redness. This type of medication works by blocking the action of histamine. This provides quick relief from symptoms like itching and tearing. However, this relief is limited to a few hours. Therefore, you may have to use these several times a day. Sometimes, these can also cause dry eyes.
Anti-inflammatory Eyedrops: For inflammation and swelling
These are divided into two main parts:
1. Nonsteroidal anti-inflammatory drugs (NSAIDs): These affect the nerve endings in the eye , changing the way it feels. Ketorolac is one of these drugs. When these are applied to the eye, you may feel a slight burning or stinging sensation.
2. Corticosteroids: These are used only for very severe and long-term allergic conditions. These cannot be bought over the counter, a doctor's prescription is required. Long-term use of these can lead to increased eye pressure (glaucoma), cataracts, and infections. Therefore, if you use these, you should definitely have your eyes checked regularly by an eye specialist.
Decongestant Eyedrops: Only for red eyes?
These can be purchased over the counter at pharmacies. When these drops are applied to the eyes, the blood vessels in the eyes constrict, quickly clearing the redness . But there is a dangerous side to this.
If you continue to use these for more than two or three days, your eyes will start to get redder than before when you stop taking the medicine. We call this 'Rebound Redness' . This is a very annoying condition. That's why doctors rarely recommend this type of eyedrops for allergies. If you have eye pressure (Glaucoma), you should not use this type of eyedrops.
Mast Cell Stabilizer Eyedrops: Let's stop allergies before they happen!
These are a relatively new type of medication. They work very well. They prevent the release of chemicals like histamine that we talked about earlier from the body in the first place. This means that they are preventative rather than reducing allergy symptoms after they occur. They can be used long-term and have fewer side effects. They may also be more suitable for people who wear contact lenses.
Multiple-Action Eyedrops: One pill does a lot of work!
As the name suggests, these contain more than one type of medicine.
- Antihistamine/Decongestant: These reduce itching and redness of the eyes. However, they are not suitable for long-term use because they contain decongestants.
- Antihistamine/Mast Cell Stabilizer: This is one of the best combinations available. It provides immediate relief (due to the antihistamine) and also prevents allergies in the long term (due to the mast cell stabilizer) . These are very useful for people with conditions like Allergic Conjunctivitis.
Be careful of these things when using eyedrops.
- Follow the instructions: Read the instructions on every medication and use it exactly as your doctor tells you.
- Use for a short time: Never use over-the-counter eyedrops for more than 2-3 days at a time without a doctor's prescription. Doing so can worsen the problem.
- Tell your doctor: If you have an eye infection or increased eye pressure (glaucoma), tell your doctor before using any eyedrops.
- Burning is normal: Some eyedrops may cause a slight burning or stinging sensation when applied to the eye. This is normal. This burning sensation can be reduced by keeping the eyedrop bottle in the fridge before use.
- Be careful with contact lenses: Many eyedrops should not be used while wearing contact lenses. Usually, you will be told to remove the lenses, apply the medication, wait at least 10 minutes, and then put the lenses back in. Ask your doctor for specific instructions on this.
