Conjunctivitis, or pinkeye, is an inflammation of the membrane covering the inside of your eyelids and the outer part of your eye. It is generally not serious but can be highly contagious. Conjunctivitis often feels like you have something in your eye that you can’t get out.

Signs and Symptoms

Conjunctivitis causes the following symptoms in one or both eyes:

  • Redness and tearing
  • Itching
  • Swollen eyelid
  • Discharge (watery or thick)
  • Crust that forms overnight
  • Sensitivity to light
  • Gritty feeling

What Causes It?

Conjunctivitis is most often the result of viruses, such as those that cause the common cold. Other causes can be bacterial infections, allergies, chemicals, irritation from contact lenses, or eye injury. Viral and bacterial conjunctivitis are very contagious. Some studies suggest that the severity of the disease is significantly associated with sun exposure.

What to Expect at Your Provider's Office

If you have conjunctivitis in both eyes, with itching and a clear discharge, allergies are likely the cause. Viral or bacterial conjunctivitis usually begins in one eye and then spreads to the other. Swollen glands and a watery or mucousy discharge usually indicate a virus, while a thick, crusty discharge may be a sign of a bacterial infection.

Your doctor may diagnose conjunctivitis from looking at your eye and asking you about your symptoms. Your doctor may also use a slit lamp for closer examination, or gently swab a stain across the surface of your eye.

Treatment Options

Conjunctivitis is generally not a serious problem and often will go away by itself. You should still, however, see your doctor. Chronic conjunctivitis, if left untreated, can cause permanent eye damage.

Treatment varies depending on what is causing the inflammation. Bacterial conjunctivitis is generally treated with antibiotic eyedrops or ointment. Viral conjunctivitis does not respond to antibiotics, but antihistamines and anti-inflammatory medications may help relieve your symptoms. Warm or cool compresses may help reduce itching and swelling.

Drug Therapies

  • Viral conjunctivitis: Generally, your doctor will let the virus run its course. Your doctor may prescribe antiviral eyedrops, such as acyclovir (Zovirax) or trifluridine (Viroptic). Treatment is supportive and may include ocular decongestants, and artificial tears. Cold compresses applied 3 times daily for 1 - 3 weeks may relieve discomfort.
  • Allergic conjunctivitis: Your doctor may recommend allergy shots, administered over several months, to reduce your sensitivity to the allergen. Antihistamine eyedrops, such as over-the-counter antazoline phosphate (Vasocon-A) or prescription olopatadine ophthalmic (Patanol), may reduce swelling or itching. An oral antihistamine can help relieve itching. A cool compress may help relieve symptoms, too.
  • Bacterial conjunctivitis: is treated with antibiotic eyedrops, such as sodium sulfacetamide (Cetamide, Bleph-10), or azithromycin, or ointment such as erythomycin (E-Mycin), bacitracin, or neomycin.

Complementary and Alternative Therapies

Alternative therapies can help relieve your symptoms. But you must make sure that any solution or compress you put on your eye is sterile. Remember, too, that you can spread conjunctivitis from one eye to another, so don’t touch your other eye while treating the affected eye. If you have a mild case of conjunctivitis, start with compresses. For a moderate case, use a compress and an eyewash that comes pre-mixed in a sterilized package or from a competent herbal practitioner.

Nutrition and Supplements

Use the following supplements, taken by mouth for up to one week, to strengthen your immune system and help you heal faster, only under your doctor's supervision. Consult a pediatrician for children's dosages.

  • Vitamin c
  • Zinc


The use of herbs is a time honored approach to strengthening the body and treating disease. Herbs, however, can trigger side effects and can interact with other herbs, supplements, or medications. For these reasons, you should take herbs with care, under the supervision of a health care provider trained in botanical medicine. Compresses and eye washes are external treatments.

A trained herbal practitioner may prescribe an herbal eyewash. The following are some examples of the herbs used in these treatments. Do not attempt these treatments on your own. You should use these treatment only under the supervision of a trained practitioner.

  • Eyebright (Euphrasia officinalis): helps fight infection and dry up excess fluid
  • Chamomile (Matricaria recutita): helps fight infection
  • Fennel seed (Foeniculum vulgare): helps fight infection
  • Marigold (Calendula officinalis): soothes irritation
  • Plantain (Plantago lanceolata, P. major): astringent and soothing. The fresh leaves are the most effective plant part.

Other herbal treatments may include:

  • Grated fresh potato has astringent (drying and disinfecting) properties. 
  • Ginkgo biloba extract with hyaluronic acid. Use of an eyewash made of this solution for one month showed a significant decrease in symptoms of conjunctivitis compared to hyaluronic acid alone.
  • Premade herbal eyewashes are available in many health food stores. Many of them contain diluted solutions of goldenseal (Hydrastis Canadensis), which in undiluted forms can be extremely irritating to the eye. Follow manufacturer's directions carefully.


Although very few studies have examined the effectiveness of specific homeopathic therapies, professional homeopaths may consider the following remedies for the treatment of conjunctivitis based on their knowledge and experience. Before prescribing a remedy, homeopaths take into account your constitutional type -- your physical, emotional, and psychological makeup. An experienced homeopath assesses all of these factors when determining the most appropriate treatment for each individual.

  • Euphrasia -- for conjunctivitis with large volumes of watery tears that burn the face and may become a thick discharge. Despite the production of watery tears, the individual may complain of a dry, gritty sensation in the eyes.
  • Argentum nitricum -- for red, swollen eyes with pus like discharge and splintering pains.
  • Pulsatilla-- for conjunctivitis with yellow green discharge and itchy eyes that may accompany or immediately follow a cold. The eyelids tend to stick together, and symptoms generally improve with cold compresses. This remedy is most appropriate for individuals who tend to be irritable and have mood swings.
  • Belladonna -- for the first stages of conjunctivitis, including the sudden onset of burning, bloodshot eyes, swollen eyelids, and hypersensitivity to light. The eyes are generally hot and throbbing to the touch.
  • Sulphur -- for burning, pain, and redness of the eyes accompanied by a yellow discharge with foul odor. The eyes are often crusted together, and the individual is usually very hot and thirsty.
  • Apis mellifica -- for red, burning, swollen  eyes that feel better with cold applications.

Following Up

Viral and bacterial conjunctivitis are both very contagious. Family members should use separate towels. Wash your hands often. Keep children home from school and day care.

Be sure to follow your doctor’s advice about using any medications, especially if you have been given antibiotics or corticosteroids. If you wear contact lenses, keep them clean to avoid further irritation and future infections. Do not wear them until your eyes have healed.

People with allergic conjunctivitis sometimes develop a severe form with a stringy discharge, swollen eyelids, scaly skin, and significant discomfort. This needs aggressive treatment to prevent scarring of the cornea.

Special Considerations

In most U.S. hospitals, a medication such as silver nitrate is routinely administered to the eyes of newborns to prevent conjunctivitis from developing from bacteria in the birth canal.
