Conjunctivitis or in common language also known as pink eye occurs when the thin lining that lies on the inner surface of the eyelid and covers the inner white surface of the eye or also called as conjunctiva, appears red or pinkish in color due to inflammation of the blood vessels in it.

How Contagious Are Conjunctivitis?

Bacterial and viral pink eye is very contagious. If the person who has conjunctivitis has it and if he/she touches his/her eye and touches your hand followed by you touching your eyes then it can get transferred to you. And as long as the symptoms remain the chance of passing out infection is also present.

Conjunctivitis During Pregnancy

There is nothing special as why conjunctivitis occurs during pregnancy and the reasons are the same as they occur in any person. But your susceptibility increases to catch conjunctivitis increases during your pregnancy period.

How is Conjunctivitis Treated?

The treatment depends on the cause and it must be treated accordingly. Here are some of the available options for you

  • Home Remedies: These are not aimed to cure your pink eye but can certainly relieve some of the symptoms which are unrelated to bacteria or virus. These are also safe to use during pregnancy. Examples include applying warm or cold compress, gentle cleansing, avoiding contact lenses and applying green tea bags.
  • Over The Counter Medicines: You can take oral anti-histamines to relive the itching/redness and/or Tylenol to lessen your pain if it’s too much.
  • Medicated eye drops: Administration of eye drops having anti-biotic can help in case of bacterial infection. But you must ask your gynecologist about which ones are safe during your pregnancy. It may take up to 7 days for you to fully heal from bacterial conjunctivitis when on eye drops. In case of allergic eye drops those containing anti-histaminic drugs can be useful. In case of viral infections if they belong to same category as common cold then no treatment is available and they will fade away on their own in about 7 to 10 days. In isolated cases where variella zoster virus and herpes virus are involved then anti-viral medicines can be prescribed. In case of chemically induced conjunctivitis gently washing with lukewarm water can help relieve the symptoms by washing away the causative chemical.

  • Avoid any contact lenses and make sure you don’t wear them without your doctor’s permission till your infection has completely subsided.
