🤱 Lactation Safety

Additional Safety Advice

If you are trying to conceive or are in early pregnancy, tell your eye doctor before using this medicine. Short-term use is generally considered acceptable when needed, but prolonged or high-dose use should be avoided unless clearly necessary. The decision should be made jointly by the patient and the treating doctor.

This medicine is often prescribed after eye surgery to control inflammation. It should be started and stopped exactly as directed by the surgeon. Using it for too long can delay wound healing and raise eye pressure, while stopping it too early can allow inflammation to return. Always keep the postoperative follow-up appointments.

There is no direct interaction between this eye drop and dental procedures. However, inform your dentist that you are using a corticosteroid eye drop, especially if you are also taking oral steroids or have diabetes, because this can affect healing and infection risk.

There is no restriction on general exercise while using this medicine. However, avoid swimming pools and contact sports until the eye has fully settled, because water and trauma can introduce infection or worsen inflammation. If you have had eye surgery, follow your surgeon's specific advice about when to resume exercise.

This medicine may cause temporary blurred vision right after instillation. Wait until your vision is clear before driving, operating machinery, or doing tasks that require sharp eyesight. Most people can continue their normal office or household work between doses. If your job involves working in a dusty environment or with chemicals, wear protective eyewear until your eye has fully recovered.

Stop this medicine when your doctor tells you to stop, or earlier if you develop a serious side effect such as severe eye pain, sudden vision loss, or a severe allergic reaction. Do not stop long-term treatment suddenly on your own, because rebound inflammation can occur. If you have been using this medicine for more than a few weeks, ask your eye doctor for a tapering plan.

Long-term use of this medicine can lead to a gradual rise in intraocular pressure, which may damage the optic nerve if it is not detected and treated. It can also cause posterior subcapsular cataract, delayed wound healing, and increased susceptibility to eye infections. Patients on prolonged therapy need regular eye pressure checks, slit-lamp examinations, and lens assessment. The lowest effective dose should be used for the shortest possible time, and the need for continued treatment should be reviewed regularly by the eye specialist.
