Bacterial conjunctivitis is often treated with prescription antibiotic eye drops. Viral conjunctivitis can sometimes be treated with antihistamine eye drops.
Some people find relief from allergic conjunctivitis with over-the-counter eye drops. Others rely on prescription allergy medications.
What Is Pink Eye?
Pink eye, also known as conjunctivitis, is a condition where the conjunctiva becomes pink or reddish color.
The conjunctiva is the clear membrane that covers a portion of the white of your eye and also lines the inside of your eyelids. When it becomes irritated, it causes swelling, and your eye appears pink or red.
How to Treat Different Types of Pink Eye
There are three main types of pink eye: bacterial, viral, and allergic. COVID conjunctivitis is also possible.
Common eye infections are often put into a single bucket, but it is helpful to realize that the causes may be quite distinct.
Viral conjunctivitis usually goes away on its own, but symptoms may be relieved with over-the-counter artificial tears. Your doctor may also prescribe antihistamine eye drops to relieve itchiness and redness or anti-inflammation eye drops to reduce swelling.
If you have bacterial conjunctivitis, expect your healthcare provider to prescribe antibiotic eye drops. These antibiotic drops are fast-acting, and you can expect your symptoms to usually improve in a couple days.
Avoid close contact with other people, especially during the first 24 hours of taking antibiotics. After that point, you are less contagious.
Allergic conjunctivitis is often treated with anti-allergy medications. This can be in the form of oral medication or eye drops.
An allergic reaction can cause the eye to be irritated, swell, and have a reddish color. Allergies may be from different substances, such as grasses, pollen, and/or dust mites. Allergy triggers can also be household cleaning supplies, perfumes, or lotions.
There are four types of allergic conjunctivitis:
- Seasonal conjunctivitis, which is caused by an allergy to pollen
- Perennial conjunctivitis, which is often caused by pet allergies or allergies to dust mites
- Contact dermatoconjunctivitis, which is caused by an allergy to cosmetics or eye drops
- Giant papillary conjunctivitis, an allergy typically caused by contact lenses
Avoid contact with substances that trigger allergies as much as possible.
Recent studies show that pink eye may be a symptom of COVID-19. Patients with more severe cases of COVID-19 are more likely to have pink eye.
Artificial tears can be used to keep the eyes moist and reduce irritation.
Over-the-Counter Eye Drops for Pink Eye
If your pink eye is from a viral infection, artificial tears are the best over-the-counter option to relieve discomfort. These drops can keep the eyes lubricated and reduce burning and itchiness.
If the eyes are well lubricated with artificial tears, you will be less likely to rub them, which can cause further irritation.
If your pink eye is caused by allergies, over-the-counter allergy eye drops may help relieve symptoms. These are generally labeled as antihistamine eye drops.
Eye Drops to Avoid if You Have Pink Eye
As tempting as it may be, do not use anti-redness eye drops when you have pink eye. Visine and other “get the red out” eye drops can irritate your eyes further.
If you only have pink eye in one eye, do not use drops in the other eye. This may inadvertently spread a bacterial or viral infection.
Don’t share your eye drops with anyone else.
Prescription Eye Drops for Pink Eye
Your doctor may prescribe eye drops based on the precise cause of your pink eye.
Antibiotic Eye Drops
According to the American Academy of Ophthalmology, bacterial conjunctivitis is the most common type of bacterial eye infection. Antibiotic eye drops can relieve symptoms and shorten the duration of the infection.
If you have allergic or viral conjunctivitis, antibiotic eye drops will not help.
Ciprofloxacin, erythromycin, tobramycin, and ofloxacin are commonly used antibiotics for bacterial conjunctivitis.
Allergy Eye Drops
Both prescription and over-the-counter allergy eye drops may contain antihistamines to control allergic reactions. This can help to reduce redness and itchiness.
Common brands of prescription antihistamine eye drops include Optivar, Livostin, and Emadine.
Some allergy eye drops contain decongestants or mast cell stabilizers.
Steroid Eye Drops
Steroid eye drops may contain steroids like prednisolone, which can reduce inflammation. Brands include Alrex and Flarex.
When to See Your Doctor About Pink Eye
If you have an eye infection, you should see an eye doctor. Pain, swelling, redness, and pus draining from the eye are all symptoms.
If you notice light sensitivity, this can indicate an eye infection as well.
Since pink eye is highly contagious, it is prudent to see a doctor early.
How to Use Eye Drops for Pink Eye
Antibiotic eye drops work best when you follow your doctor’s instructions precisely.
The American Academy of Ophthalmology offers these recommendations for how to put in eye drops:
- Wash your hands thoroughly.
- Take out contact lenses if you wear them.
- Tilt your head back and look up.
- Pull your lower eyelid down with one hand while you hold the eye drop bottle with the other.
- Release one to two drops into the eye, according to the instructions.
- Take extra precautions to not touch the tip of the eye drop container.
Be sure to use the entire course of eye drops, as prescribed. It may seem tempting to stop if you feel better, but medical experts advise taking the full dose.
What if Your Pink Eye Doesn’t Go Away?
Pink eye will generally go away within two weeks without treatment. If your pink eye doesn’t go away after this point or if it appears to worsen rather than improve on a daily basis, see an optometrist or ophthalmologist.
It could be a sign that something else is going on with your eye.
Dos & Don’ts With Pink Eye
Follow these tips to ensure you don’t spread pink eye to your other eye or to others:
- Avoid close contact with others until your symptoms resolve.
- Do not swim while you have the infection.
- Do not share towels, sheets, or washcloths with others.
- Do not share eye makeup or cosmetics.
- Throw out old eye makeup after having conjunctivitis.
- Do not share eye drops with anyone else.
