Additional Common Questions

What type of drug is naphazoline?

Naphazoline is an ocular (eye) decongestant that works by narrowing blood vessels in your eye. Specifically, it narrows arterioles in the thin, clear membrane (conjunctiva) that covers the white of your eye (sclera). This narrowing of blood vessels (vasoconstriction) temporarily reduces redness in your eye. Red eye happens when blood vessels in your eye are too wide open. 

Some eye drop formulas combine naphazoline and additional ingredients to target other symptoms besides redness. For example, you might see glycerin, polyethylene glycol 300, polysorbate 80 or hypromellose on the drug label. These are all lubricants that help ease minor eye irritation or burning.

If you have dry eye disease, avoid products containing naphazoline. These drops won’t help your symptoms and might make them worse. Instead, use artificial tears to soothe your eyes — but only after talking to a healthcare provider about which eye drops or other treatments are best for you.

Is naphazoline an antihistamine?

No, naphazoline isn’t an antihistamine. But certain eye drops contain naphazoline along with antihistamines, like pheniramine. These eye drops treat eye irritation due to allergies. Naphazoline reduces redness, while the antihistamine relieves itchiness. 

Can I use naphazoline every day?

No. Naphazoline is only meant for short-term use. You can use it for up to three days in a row (72 hours). After that point, if your eyes are still red, contact a healthcare provider. You shouldn’t use naphazoline long term because:

  • It can lead to rebound redness. This is the main side effect of naphazoline on your eyes. It’s when eye redness returns after you stop using the eye drops — and the redness may look even worse than it did before using the drops. If you use drops again to treat the rebound, that could lead to a cycle of rebound redness. This issue can occur if you use an ocular decongestant like naphazoline or tetrahydrozoline for too long.
  • It can mask symptoms of a condition that needs treatment. Often, red eye is minor and nothing to worry about. It might happen because you’re tired or because of irritants like smoke or dust. But red eye can also be a symptom of a condition like conjunctivitis (pink eye), glaucoma or an eye injury. Using naphazoline in certain types of glaucoma can worsen your symptoms. If you use drops to mask the redness, you’re not treating the underlying problem (and could delay treatments that are more likely to help).

If you have any other symptoms besides redness — like eye pain, eye discharge or changes in your vision — talk to a healthcare provider as soon as possible. Don’t try to treat the issue yourself.

When should I seek medical care?

Call a healthcare provider if you have red eye and:

  • Your eyes feel tender and/or painful.
  • The area around your eye is bruised, swollen or painful.
  • You have blurred vision or other vision changes.
  • You have new or worsening sensitivity to light.
  • Your symptoms last beyond a week or seem to be getting worse.
  • Pus or mucus is coming out of your eyes.
  • You have a fever.
  • You’ve had close contact with someone who has conjunctivitis (pink eye).

A note from Cleveland Clinic

There’s no convenient time to have red eye, but certain days — like family photo or job interview days — are worse than others. When you want to quickly get your eyes looking white and bright, naphazoline or similar products might help.

This is assuming you have no other symptoms (like eye pain) that could point to a more serious concern. Using eye drops to reduce redness may mask an underlying problem that needs timely diagnosis and treatment.

If you do use eye drops to treat redness, proceed with caution. Naphazoline and other ocular decongestants can cause rebound redness if you use them for too long. They’re not meant to be a long-term solution, and they won’t treat the underlying cause of redness.

When it comes to your eyes, you can never be too safe. If you don’t know why your eyes are red, or if you have other symptoms, contact a healthcare provider. They’ll get to the bottom of the situation and make sure eye drops aren’t masking an issue that needs proper treatment.
