Do you sometimes wake up in the morning with red, itchy eyes that are difficult to open? At such times, when you go to a doctor, he or she may prescribe you eye drops. Moxifloxacin is a drug that is commonly prescribed for bacterial infections of the eyes. Today, we will talk about this in a simple way that you can understand.
What is Moxifloxacin?
Simply put, Moxifloxacin is an antibiotic. To be precise, it belongs to the quinolone class of antibiotics. Its main function is to kill bacterial eye infections that occur inside the eyes.
The most important thing is that this medicine only works for bacterial infections. It will not help with eye infections caused by a virus (e.g. viral conjunctivitis). Therefore, it is not recommended to use it without the advice of a doctor.
In Sri Lanka, you can find this medicine under brand names like Vigamox and Moxeza.
Things to tell your doctor before using this medicine
It's important for your doctor to know some information about you before prescribing this medication. So if any of the following apply to you, be sure to tell your doctor.
- If you are a contact lens wearer.
- If you have previously had an allergic reaction to Moxifloxacin or other similar fluoroquinolone medications (such as Ciprofloxacin).
- If you have allergies to any other medicines, foods, dyes, or preservatives.
- If you are pregnant or expecting a baby .
- If you are a breastfeeding mother .
Based on this information, it will be easier for the doctor to decide whether this medication is right for you or not.
How do you use these eye drops correctly?
To get the full benefit of the medicine, you need to apply it correctly. Imagine, I'm telling you. Follow these steps.
1. Hand washing: First, wash your hands thoroughly with soap and clean them.
2. Preparing the bottle: Do not touch the tip of the medicine bottle to anything, including your fingers or your eyes. Doing so can harbor germs.
3. Eye preparation: Tilt your head back slightly and gently pull down the eyelid under your eye with your index finger to create a small pouch.
4. Putting the medicine: Put the medicine drops into the prepared bag in the amount prescribed by the doctor (e.g. one or two drops).
5. Eyelid surgery: Gently close your eye and gently press the corner of your eye (on the nose side) with your finger for about 30 seconds. This will help keep the medicine from going down your throat and stay inside your eye.
6. Be patient: Your vision may be slightly blurred for a few minutes after applying the medication, which is normal. During this time, avoid activities that require alertness, such as driving.
Very important: You should take this medicine for the full course prescribed by your doctor. Do not stop taking it just because your symptoms have improved in two or three days. If you do, the infection may come back.
What if it is used for small children?
Doctors prescribe this medicine for young children, sometimes even newborns. But only your doctor should decide. Therefore, do not use this medicine on children without medical advice.
What if the medicine is used too much?
If you think you have overdosed on this medicine, do not panic. However, immediately call the National Poisons Information Centre at the Colombo National Hospital , or go to the Emergency Treatment Unit (ETU) of the nearest hospital.
If I forget to take the medicine, is there any interaction with other medicines?
If you forget to take your medicine...
If you forget to take a dose, take it as soon as you remember. However, if it is almost time for your next dose (for example, within an hour or two), skip the missed dose and take your next dose at the scheduled time. Never take a double dose.
Interactions with other medications
These eye drops do not usually interact with other medications. However, if you are using any other eye drops, it is essential to tell your doctor about them. If you are using two types of medication, leave at least 5-10 minutes between the two.
