Do you wake up in the morning with tired, red eyes? Or do your eyes sting and burn after staring at your computer screen or dealing with dust all day?
If this sounds familiar, you are not alone. Many people reach for over-the-counter eye drops like Naphazoline to find quick relief.
While these drops can clear up redness fast, you need to understand how they work and how to use them safely. Let us take a close look at Naphazoline eye drops and what you need to know before putting them in your eyes.
Key Takeaways at a Glance
- Naphazoline eye drops temporarily narrow small blood vessels in your eyes to reduce redness and mild irritation.
- Always talk to your doctor before using them, especially if you have glaucoma, high blood pressure, or take certain medicines.
- Never touch the tip of the dropper to your eye or fingers to prevent germ contamination.

What Kind of Medicine is Naphazoline?
Simply put, Naphazoline is a decongestant medicine. It temporarily shrinks the tiny blood vessels in your eyes, which quickly clears away the red color and gives your eyes a clear look.
People usually use these eye drops for:
- Mild eye redness and burning caused by dust, smoke, pollen, or smog.
- Eye redness caused by everyday eye strain and tiredness.
You can find this active ingredient under many different brand names depending on your country, such as AK-Con, Naphcon, and Albalon. Even though the brand names vary, the active medicine inside is Naphazoline.
Things to Tell Your Doctor Before Using This Medicine
Even though you can buy these drops off the shelf at many pharmacies, you should talk to your doctor or pharmacist first. This is very important if any of the following health conditions apply to you:
- You have glaucoma, which is an eye condition involving increased pressure inside the eye.
- You have known allergies to Naphazoline, or any other medicines, foods, preservatives, or dyes.
- You are pregnant, planning to become pregnant, or currently breastfeeding a baby.
Sharing your complete medical history with your doctor helps you avoid unexpected complications and keeps your eyes safe.
How to Use Your Eye Drops Correctly
To get the full benefit of your medicine, you must put the drops into your eyes correctly. It is quite simple if you follow these clear steps:
- Wash your hands: Always start by washing your hands thoroughly with soap and water.
- Shake the bottle: Gently shake the medicine bottle before you use it.
- Prepare your eye: Tilt your head back slightly and use your index finger to gently pull down your lower eyelid to form a small pocket.
- Apply the drops: Look up and squeeze one or two drops (as directed by your doctor or product label) into the pocket you just made.
- Protect the dropper: Make sure the tip of the dropper never touches your eye, your fingers, or any other surface. Touching the tip can transfer germs and ruin the entire bottle of medicine.
- Close your eye: After putting the drop in, gently close your eye and keep it shut for a few seconds to let the medicine spread evenly. Do not squeeze your eyelids tightly shut.
- Clean your hands again: Wash your hands thoroughly with soap and water once you finish.
When to Call Emergency Services
If you accidentally use too much of this medicine or swallow it, take immediate action. Call 911 (US/Canada), 999 (UK), or your local emergency number right away, or go directly to the nearest Emergency Department (ER or A&E). You can also contact your regional poison control center.
Remember that eye drops are prescribed or bought for personal use. Never share your eye drops with family members or friends.
Giving Naphazoline to Small Children
If you are thinking about giving this medicine to a young child, you must consult a pediatrician first. Children require special medical guidance, and certain eye drops may not be safe for very young kids.
Does Naphazoline Interact With Other Medicines?
Yes, certain medicines can interact with Naphazoline. You must be very careful if you take other medicines for ongoing health conditions.
Pay special attention if you take these types of drugs:
- Medicines used for depression, anxiety, or mood disorders.
- Monoamine Oxidase Inhibitors, commonly known as MAOIs (examples include Carbex, Eldepryl, Marplan, Nardil, and Parnate).
- Maprotiline, a medicine used for depressive disorders.
This list does not include every possible interaction. Always give your doctor a complete list of everything you take, including vitamins, herbal remedies, and daily supplements. If you smoke or drink alcohol regularly, let your doctor know as well.
Things to Watch Out For and Possible Side Effects
If your eye symptoms do not get better within two or three days, or if they actually get worse, stop using the drops and call your doctor. Never use this medicine for longer than recommended. Using decongestant drops continuously can cause your blood vessels to dilate even more once the medicine wears off, leading to worse redness known as rebound redness.
After you put the drops in, your vision may become temporarily blurry. Wait until your vision clears up completely before you drive a car, operate heavy machinery, or do tasks that require sharp, clear eyesight.
