What Tetracycline is used for
Tetracycline is an important antibiotic medicine used to treat several eye conditions caused by infections. It is effective against a range of bacteria that can affect your eyes.
- Trachoma: This is a serious eye infection that can lead to blindness if not treated. Tetracycline has historically been a key medicine in controlling this condition.
- Chlamydial Conjunctivitis: An infection of the conjunctiva (the clear membrane covering the white part of your eye and the inside of your eyelids) caused by Chlamydia bacteria.
- Bacterial Conjunctivitis: Also known as ‘pink eye,’ this is an inflammation of the conjunctiva caused by various types of bacteria.
- Blepharitis: An inflammation of the eyelids, often at the base of the eyelashes, which can be caused or worsened by bacterial infection.
Your eye doctor will prescribe Tetracycline if they determine that your eye condition is caused by one of these infections and that this medicine is the most suitable treatment for you.
How it works
Tetracycline belongs to a group of medicines called antibiotics. It works by stopping the growth of bacteria that cause eye infections. It is considered a ‘broad-spectrum’ antibiotic, meaning it is effective against a wide variety of bacteria. Specifically, Tetracycline works by inhibiting the production of essential proteins that bacteria need to grow and multiply. By stopping this process, the bacteria cannot spread, and your body’s immune system can then clear the existing infection, helping your eyes heal.
How it’s used
Tetracycline eye ointment is typically applied to the affected eye(s) 2 to 4 times a day, or exactly as directed by your eye doctor. It is very important to follow your doctor’s instructions precisely regarding the frequency and duration of use. Do not stop using the ointment even if your symptoms improve, unless advised by your doctor, as stopping early can lead to the infection returning or becoming harder to treat.
When applying eye ointment, always wash your hands thoroughly with soap and water before and after. Gently pull down your lower eyelid to create a small pocket. Squeeze a small amount of ointment (usually a thin strip about 1 cm long) into this pocket without touching the tip of the tube to your eye or any other surface. Close your eye gently for a minute or two to allow the medicine to spread. If you are using other eye drops or ointments, wait at least 5-10 minutes between applications.
Always follow your ophthalmologist’s exact instructions.

Precautions & side effects
Tetracycline is a powerful medicine and comes with important precautions that you must be aware of. Always discuss your full medical history with your doctor before starting this treatment.
- Prescription Required: This medicine is a prescription-only drug. You must use it only under the guidance and prescription of a qualified eye doctor.
- Pregnancy and Breastfeeding: Tetracycline is NOT for use in pregnancy or during breastfeeding. It can affect the developing baby or infant. If you are pregnant, planning to become pregnant, or breastfeeding, please inform your doctor immediately.
- Children Under 8 Years: This medicine is NOT for use in children under 8 years of age. It can affect the development of their teeth and bones, potentially causing permanent discolouration of teeth.
- Sun Sensitivity: Tetracycline can make your skin more sensitive to the sun. While using this medicine, it is important to use sun protection, such as wearing sunglasses, hats, and protective clothing, and avoiding prolonged exposure to direct sunlight.
- Hydration: If you are prescribed the oral form of Tetracycline, it is important to take it with plenty of water and remain sitting upright for some time after taking the dose to prevent irritation of the food pipe.
- Historic Use: Tetracycline has been a historic mainstay in the control and treatment of trachoma, highlighting its effectiveness in combating this severe eye infection.
Always complete the full course of treatment as prescribed by your doctor, even if your symptoms improve. Stopping early can lead to the infection coming back or becoming resistant to treatment.
Understanding Eye Infections and Your Treatment
Eye infections can be uncomfortable and, if left untreated, can sometimes lead to more serious problems. Conditions like conjunctivitis (pink eye), blepharitis (eyelid inflammation), and trachoma are often caused by bacteria. When bacteria enter the eye, they can multiply and cause redness, irritation, discharge, and sometimes pain. Your doctor has prescribed Tetracycline eye ointment because it contains an antibiotic that specifically targets these bacteria, helping to clear the infection and allow your eyes to heal. It’s important to understand that while your symptoms might start to improve quickly, the bacteria may still be present. That’s why completing the full course of treatment, even if you feel better, is crucial to ensure all the infection is cleared and to prevent it from returning.
If you have been diagnosed with trachoma, it’s important to know that this is a serious bacterial infection that can cause roughing of the inner eyelid, leading to eyelashes scratching the cornea and potentially causing irreversible blindness. Tetracycline has played a vital role in global efforts to control and eliminate trachoma. Following your doctor’s instructions for treatment is a key step in preventing the progression of this disease and protecting your vision.
Correct Application and Hygiene for Eye Ointments
Using eye ointment correctly is just as important as the medicine itself. Before you touch your eyes or the ointment tube, always wash your hands thoroughly with soap and water. This prevents introducing new germs into your eyes. When applying the ointment, gently pull down your lower eyelid to create a small pocket. Hold the ointment tube above your eye and squeeze a thin strip of ointment (about 1 cm long) into this pocket. Be very careful not to let the tip of the tube touch your eye, eyelid, or any other surface, as this can contaminate the ointment. After applying, close your eye gently for a minute or two to allow the medicine to spread across the eye surface. If you need to apply ointment to both eyes, repeat the process. If you are using other eye drops or ointments, wait at least 5 to 10 minutes between applications to allow each medicine to be absorbed properly. After application, wash your hands again to remove any residue.
Maintaining good hygiene is essential throughout your treatment. Avoid sharing eye makeup, towels, or pillowcases, as these can spread infection. Clean your eyelids gently if there is any discharge, using a clean cotton ball or tissue soaked in warm water. Always store your eye ointment as directed by your doctor or pharmacist, usually at room temperature and away from direct sunlight. Never use an ointment past its expiry date. If the ointment changes colour or consistency, or if the tube appears damaged, do not use it and consult your pharmacist.
When to Seek Medical Help
While Tetracycline is effective in treating eye infections, it’s important to know when to seek further medical attention. If your symptoms worsen, do not improve after a few days of treatment, or if you develop new symptoms such as severe pain, sudden vision changes, or increased redness and swelling, contact your eye doctor immediately. These could be signs that the infection is not responding to the treatment, or that you have a different type of eye problem that needs attention. Also, if you experience any unexpected side effects, such as a severe allergic reaction (e.g., rash, itching, swelling, severe dizziness, trouble breathing), stop using the medicine and seek emergency medical help right away. Remember, your eye doctor is your best resource for managing your eye health, and it’s always better to be safe and get professional advice if you have any concerns during your treatment.
