1. WHAT IOPIDINE IS AND WHAT IT IS USED FOR

Iopidine contain apraclonidine (as hydrochloride) as the active substance.

Iopidine belongs to a group of medicines known as alpha agonists.

It is used in the treatment of chronic glaucoma in people who are already receiving other medicines to treat this disease.

In these people, Iopidine helps to reduce the fluid pressure in the eye and can delay the need for pressure relieving eye surgery.

2. WHAT YOU NEED TO KNOW BEFORE YOU USE IOPIDINE

Do not use Iopidine:

  • If you have a history of severe or unstable heart disease or circulatory problems.
  • If you are allergic to apraclonidine, clonidine or any of the other ingredients of this medicine listed in section 6.
  • If you are currently taking monoamine oxidase inhibitors antidepressants or tricyclic antidepressants.
  • If you are currently taking medicines of the class of sympathomimetics that are taken either orally or via injection.
  • In CHILDREN.

Ask your doctor for advice.

Warnings and precautions

Take special care:

  • Only use Iopidine for dropping in your eye(s).
  • Iopidine may not continue to control your eye pressure after you have used them for a period of time. Your doctor will examine you often while you are using Iopidine to see whether the eye drops are still working for you.
  • As Iopidine decreases the pressure in your eye(s), you should have your eye pressure checked regularly to ensure that the pressure in your eye(s) remains under control.

If you have a history of, or are taking medicine to treat, any of the following:

  • Any heart disease (including angina, heart attacks or heart failure)
  • High blood pressure or other circulatory problems (including stroke, Raynaud’s disease and fainting spells)
  • Kidney or liver problems
  • Depression
  • Parkinson's disease
  • Diabetes or low blood sugar. Iopidine may hide the signs and symptoms of a sudden reduction in blood sugar such as a fast heart beat or trembling.
  • If you are due to have an operation.

If any of these apply, you may still be able to use Iopidine, but discuss it with your doctor first.

Using Iopidine with food, drink and alcohol

No alcohol should be consumed during treatment with Iopidine as it can increase its effects.

Other medicines and Iopidine

Tell your doctor or pharmacist if you are taking or have recently taken any other medicines, including medicines obtained without a prescription. Iopidine must not be used if you are taking monoamine oxidase inhibitor antidepressants or tricyclic antidepressants. Iopidine must also not be used if you are taking medicines of the class of sympathomimetics that are taken either orally or via injection. Iopidine may increase the effects of some medicines used to treat - depression - asthma – high blood pressure – heart medicines containing digoxin or digitoxin – some forms of mental illness and Parkinson’s disease; and may interact with - some pain killers - sedatives – anaesthetic – tricyclic antidepressants - phenothiazines - cough and cold remedies – glaucoma medications such as timolol, brimonidine or dipivefrine - eye drops used to whiten the eye.

Pregnancy and breast-feeding

If you are pregnant or breast-feeding, think you may be pregnant, or are planning to have a baby, ask your doctor or pharmacist before taking this medicine.

Iopidine should not be used during pregnancy or breast-feeding.

Driving and using machines

This type of medicine may cause you to feel sleepy and dizzy. If you do, you should not drive or operate machinery.

Important information if you wear Contact Lenses

Iopidine contains benzalkonium chloride

This medicine contains 0.1 mg of benzalkonium chloride in each ml of the product which is equivalent to 0.01%.

IOPIDINE contains a preservative (benzalkonium chloride) which 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 IOPIDINE

The recommended dose is 1 drop into your eye(s), 3 times each day.

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

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

How to use

  • Wash your hands before you start.
  • 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.
  • 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 Iopidine, press a finger into the corner of your eye, by the nose (picture 3). This helps to stop Iopidine 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 Iopidine is swallowed, see your doctor immediately.
  • If you forget to use Iopidine
  • Continue with the next dose as planned. However, if it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule.
  • Do not take a double dose to make up for a forgotten dose.
  • If you use more Iopidine than you should rinse it all out with warm water. Do not put in any more drops until it is time for your next regular dose. In case of accidental ingestion, symptoms of overdose may include decreased blood pressure, drowsiness, decreased heart rate, hypoventilation (reduced rate and depth of breathing), and convulsion.

If you are using other eye drop or eye ointment medicines

Leave at least 5 minutes between each medicine. Eye ointments should be administered last.

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