Patient leaflet - Maxitrol eye drops

1. What MAXITROL* is and what it

is used for

MAXITROL contains a steroid,

dexamethasone and two antibiotics,

neomycin sulphate and polymyxin B

sulphate.

It is used for the short term treatment of inflammation of the eye, where administration of an antibiotic is also required to prevent an eye infection.

2. What you need to know before

you use MAXITROL

Do not use MAXITROL...

  • If you have any type of infection of the eye that is not being

    treated including viral, fungal or

    untreated parasitic eye infections

    or Tuberculosis of the eye. Use of

    steroids may make infections worse.

  • If you have a red eye that has not been seen by a doctor.
  • If you are allergic to dexamethasone, neomycin, polymyxin B or to any of the other ingredients listed in section 6. Ask your doctor for advice.

Take special care...

  • Do not inject or swallow this medicine.
  • Consult your doctor or pharmacist before using this medicine if you have a disorder causing a thinning of the eye tissues.
  • Consult your doctor or pharmacist if your eye pain, redness, swelling, or irritation gets worse or persists. You may become more susceptible to eye infections with the use of this product.
  • If you experience allergic reactions with Maxitrol, discontinue use and consult your doctor. Allergic reactions may vary from localized itching

    or skin redness to severe allergic

    reactions (anaphylactic reaction) or serious skin reactions. These allergic reactions may occur with other topical or systemic antibiotics of the same family (aminoglycosides).

  • Steroids applied to the eye may

    delay the healing of your eye wound. Topical NSAIDs (Non-Steroidal Anti Inflammatory Drugs- Medications) are also known to slow or delay healing. Simultaneous use of topical NSAIDs and topical steroids may increase the potential for healing problems.

  • If you use MAXITROL for a long period of time you may:

    Have increased pressure in your eye(s). You should have your eye pressure checked regularly while using Maxitrol. This is especially important in children, as the

    risk of corticosteroid-induced

    increased pressure in the eye may be greater in children and may

    occur earlier than in adults. The risk of corticosteroid-induced

    increase intraocular pressure

    and/or cataract formation is

    increased in predisposed patients (e.g. diabetes).

    Develop cataract

    Become more susceptible to eye infections

  • Talk to your doctor if you experience swelling and weight gain around the trunk and in the face as these are

    usually the first manifestations of a syndrome called Cushing’s syndrome. Suppression of the adrenal gland

    function may develop after stopping a long-term or intensive treatment with MAXITROL. Talk to your doctor before stopping the treatment by yourself. These risks are especially important

    in children and patients treated with a drug called ritonavir or cobicistat.

    • Contact your doctor if you experience blurred vision or other visual disturbances.
    • Talk to your doctor before using Maxitrol if you have diabetes or have a family history of diabetes.

Pregnancy and breast-feeding

MAXITROL is not recommended during pregnancy or breast-feeding. If you are pregnant or might get pregnant, or if you are breast-feeding a baby, talk to your doctor before you use MAXITROL.

Driving and using machines

You may experience blurred vision after using MAXITROL. Do not drive or use any machines unless your vision is normal.

Other medicines and MAXITROL

Tell your doctor or pharmacist if you are taking or have recently taken any other medicines, including medicines obtained without a prescription. Taking MAXITROL with other medicines may increase the seriousness of the side effects.

Especially tell your doctor if you are using:

  • Topical NSAIDs. Simultaneous use of topical steroids and topical NSAIDs may increase healing problems in your eye.

Tell your doctor if you are using ritonavir or cobicistat, as this may increase the amount of dexamethasone in the blood. Tell your doctor if you are diabetic and you are taking, having recently taken or might take medicines for treatment of diabetes such as insulin, metformin or sulfonylureas such as chlorpropamide, as Maxitrol may decrease the blood glucose lowering effect of these medicines

Important information if you wear Contact Lenses

Wearing contact lenses is not advisable during the treatment of an eye infection, as they may make your condition worse. There is a preservative in MAXITROL (benzalkonium chloride). This medicine contains 0.2 mg Benzalkonium Chloride in each 5 ml which is equivalent to 0.04 mg/ml. Benzalkonium chloride may be absorbed by soft contact lenses and may change the colour of the contact lenses. You should remove contact lenses before using this medicine and put them back 15 minutes afterwards.

Benzalkonium chloride may also cause eye irritation, especially if you have dry eyes or disorders of the cornea (the clear layer at the front of the eye). If you feel abnormal eye sensation, stinging or pain in the eye after using this medicine, talk to your doctor.

3. How to use MAXITROL

The recommended dose is 1 or 2 drops into the space between your eyelid and eye 6 times daily, or more frequently if required.

Remove the loose collar from the cap when the bottle is first opened.

How to use

  • Wash your hands before you start.
  • Shake the bottle well.
  • Twist off the bottle cap.
  • Hold the bottle pointing

    down, between your

    thumb and fingers.

  • Tilt your head back.
  • Pull down your lower

    eyelid with a finger,

    until there is a ‘pocket’

    between the eyelid and

    your eye. The drop will

    go in here (picture 1).

  • Bring the bottle tip

    close to the eye. Do this in front of a mirror if it helps.

  • Do not touch your eye or eyelid, surrounding areas or other surfaces with the dropper. It could infect

    the drops.

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

    MAXITROL should not be used for a long period of time unless advised by your doctor.

    • Gently press on the base of the bottle to release one drop at a time (picture 2).
    • Do not squeeze the bottle, only a gentle press on the

      bottom is needed.

    • After using Maxitrol,

      keep the eyelid

      closed, while applying

      gently pressure to the

      corner of your eye by

      the nose (picture 3).

      This helps to reduce the amount of medicine getting into the rest of the body.

    • If you use drops in both eyes, repeat the steps for your other eye. Put the bottle cap firmly back on immediately after use.
  • If a drop misses your eye,

    try again.

  • If you forget to take MAXITROL, do not worry, just take it as soon as possible.

    Do not take a double dose to make up.

  • If you use more MAXITROL than you should it can be washed out of your eye with warm water.

    • If you are using other eye drops, wait at least 5 minutes after putting in MAXITROL before using the other eye drops. Eye ointments should be administered last.

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