FML is an eye drop. It contains a steroid which is used to treat inflammation of the eye.


Do not use FML

  • if you are allergic (hypersensitive) to fluorometholone, benzalkonium chloride, or any of the other ingredients of FML.
  • if you have a bacterial, viral, or fungal infection of the eye.

Take special care with FML

You should not use FML for more than one week unless your doctor or eye specialist advises it.

Prolonged use may cause the pressure inside your eye (intraocular pressure) to increase, which could lead to glaucoma, rare damage to the optic nerve, lack of clearness of vision, cataracts, delay in wound healing, or the development of an eye infection. The pressure in your eye will be regularly measured.

If you have or have been previously treated for herpes simplex, use FML only under close supervision of your doctor.

The use of the bottle by more than one person may spread infection.

Contact your doctor if you experience blurred vision or other visual disturbances.

Using other medicines

Please tell your doctor if you are taking or have recently taken any other medicines, including medicines obtained without a prescription.

Some medicines may increase the effects of FML and your doctor may wish to monitor you carefully if you are taking these medicines (including some medicines for HIV: ritonavir, cobicistat).

If you are using other eye drops, leave at least 5 minutes before putting in FML.


The safety and effectiveness in children aged 2 years or less have not been shown.

Pregnancy and breast feeding

Tell your doctor before you start using FML if you are pregnant or planning to become pregnant or if you are breastfeeding. Your doctor will decide if you should use FML during pregnancy or whilst breastfeeding. Normally it is not recommended for use.

Driving and using machines

FML can cause temporary blurred vision. Should this occur, wait for the blurring to clear before driving or operating machinery or taking part in any activity where this could put yourself or others at risk.

Important information about some of the ingredients of FML

FML contains benzalkonium chloride as a preservative, which is known to discolour soft contact lenses and can cause eye irritation. If you wear soft contact lenses you must remove them before using FML eye drops and wait at least 15 minutes before putting your lenses back in.

Ask your doctor or pharmacist for advice before taking any medicine.


Always use FML exactly as your doctor has told you. You should check with your doctor or pharmacist if you are not sure.

The usual dose is 1 or 2 drops of FML in each eye that needs treatment 2 to 4 times a day, or more frequently if your doctor advises it. During the first 24 - 48 hours of treatment your doctor may advise you to apply 2 drops at one hour intervals.

Treatment should not be withdrawn too early.

Instructions for use

You must not use the bottle if the seal on the bottle neck is broken before you first use it.

Shake the bottle before use. Wash your hands before opening the bottle.

Use your eye drops in the following way:

1. Tilt your head back and look at the ceiling.
2. Gently pull down the lower eyelid until there is a small pocket.
3. Turn the bottle upside down and gently squeeze it to release 1 or 2 drops into the eye.
4. Let go of the lower lid, and close your eye for 30 seconds.
5. Repeat steps 2 to 4 for the other eye, if it also needs treatment.

If a drop misses your eye, try again.

To keep the eye drops free from contamination and avoid eye injury, do not let the tip of the bottle touch your eye or anything else. Put the cap back on and close the bottle tightly straight after use. Wipe off any excess liquid from your cheek with a clean tissue.

If you use more FML than you should

If you use more drops of FML than you should, it is unlikely to cause you any harm. If you have placed too many drops in your eye(s), wash your eyes with clean water. Put your next dose in at the usual time.

If you drink FML by accident

If anyone drinks FML by accident, it is unlikely to cause any harm. The affected person should drink fluids to dilute.

If you forget to use FML

If you forget a dose, use FML as soon as you remember, unless it is almost time for your next dose. Then use your next dose at the usual time. Do not take a double dose to make up for a forgotten dose.

If you stop using FML

To work properly FML should be used as advised by your doctor or pharmacist.

If you have any further questions on the use of this product, ask your doctor or pharmacist.
