What Oraqix is used for

Oraqix is a gel that is used for local anaesthesia in tooth pockets. It is used in adults to stop or relieve pain during certain types of dental procedures, such as scaling, probing and root planing.

Oraqix is only available from your dental practitioner.

This medicine belongs to a group of medicines called local anaesthetics.

It works by making the nerves unable to pass messages to the brain.

Depending on the amount used, Oraqix will either totally stop pain or will cause a partial loss of feeling.

Ask your dental practitioner if you have any questions about why this medicine has been prescribed for you.

This medicine is not expected to affect your ability to drive a car or operate machinery.

There is not enough information to recommend the use of this medicine for children and adolescents under the age of 18.

Before you are given Oraqix

When you must not be given it

You must not be given Oraqix if you have an allergy to:

  • any medicine containing lignocaine and prilocaine
  • any of the ingredients listed at the end of this leaflet
  • any other similar medicines.

Some of the symptoms of an allergic reaction may include:

  • shortness of breath
  • wheezing or difficulty breathing
  • swelling of the face, lips, tongue or other parts of the body
  • rash, itching or hives on the skin.

You must not be given Oraqix if you have congenital or idiopathic methaemoglobinaemia.

A small amount of haemoglobin is normally present in the blood in a modified form called methaemoglobin. Methaemoglobinaemia is a condition where an excess of haemoglobin has changed into methaemoglobin. If too much methaemoglobin is formed, it becomes more difficult for the blood to provide the tissue with oxygen.

You must not be given Oraqix if you have porphyria that keeps going away and coming back.

Porphyrias are a group of conditions that affect the way your blood is made. Porphyrias may mean your blood is not as red as it should be. You may also have liver, skin or nerve problems.

You will not be given this medicine after the expiry date printed on the pack or if the packaging is torn or shows signs of tampering.

If you are not sure whether you should be given this medicine, talk to your dental practitioner.

Before you are given it

Tell your dental practitioner if you have allergies to any other medicines, foods, preservatives or dyes.

Tell your dental practitioner if you have or have had any of the following medical conditions:

  • glucose-6-phospatase dehydrogenase deficiencies
  • kidney or liver disease
  • irregular heart activity
  • mouth ulcers or an infection in your mouth.

Tell your dental practitioner if you are pregnant or plan to become pregnant or are breast-feeding. Your dental practitioner can discuss with you the risks and benefits involved. Oraqix should not be used in pregnancy unless clearly necessary.
You can continue to breast-feed after treatment with Oraqix.

If you have not told your dental practitioner about any of the above, tell him/her before you are given Oraqix.

Taking other medicines

Tell your dental practitioner if you are taking any other medicines, including any that you get without a prescription from your pharmacy, supermarket or health food shop.

Some medicines and Oraqix interfere with each other. These include:

  • medicines used to treat irregular heart activity (antiarrhythmics), such as mexiletine
  • other medicines that can cause methaemoglobinaemia (e.g. certain kinds of antibiotics known as sulfonamides).

These medicines may be affected by Oraqix or may affect how well it works. You may need different amounts of your medicines, or you may need to take different medicines.

Your dental practitioner and pharmacist have more information on medicines to be careful with or avoid while being given this medicine.

How Oraqix is given

Follow all directions given to you by your dental practitioner carefully. They may differ from the information contained in this leaflet.

A dental practitioner will give you Oraqix. The dosage is decided by the dental practitioner and depends on how many and which teeth are to be treated.

The maximum dose in a single treatment is 5 cartridges. The gel is applied inside the tooth pocket by the Oraqix™ dispenser and a blunt-tipped applicator.

Oraqix is not injected. The full effect is achieved after about half a minute and the dental practitioner can start further treatment.

You may receive other local anaesthetics at the same treatment session.

Frequent use of large amounts of Oraqix is not recommended.

If you have the impression that the effect of Oraqix is too strong or too weak, talk to your dental practitioner.

If you are given too much (overdose)

The dental practitioner giving you Oraqix will be experienced in the use of local anaesthetics, so it is unlikely that you will be given an overdose.

However, if too much local anaesthetics (i.e. Oraqix in combination with dental injection) have been given, the following side effects may occur: numbness of the lips and around the mouth, nervousness, light-headedness, dizziness, shakiness, or sometimes blurred vision, drowsiness and loss of consciousness. Other rare effects are fits, breathlessness and lowered blood pressure.

Tell your dental practitioner immediately if you have any of the above symptoms.

Too much prilocaine (Oraqix in combination with dental injection) may also increase the methaemoglobin level and cause methaemoglobinaemia.

Methaemoglobinaemia is characterised by slate-grey cyanosis, a bluish-grey discoloration of the lips and the skin. (Methaemoglobinaemia is explained in the section “Before you are given it”.)

If you have any of the above symptoms, contact your dental practitioner or doctor, or go to Accident and Emergency at your nearest hospital for assessment of the risk and advice. You may need to be watched for several hours.

While you are using Oraqix

Things to be careful of

Caution must be exercised in the use of Oraqix gel. If the gel comes into accidental contact with the eye, the eye must be washed with water immediately or saline solution and protected until you recover feeling in it.

Oraqix may occasionally block all feeling in the treated area, so be careful to avoid accidental injury. Do not eat or drink anything until the feeling has returned to your mouth. You may burn or bite yourself.

Oraqix may interfere with tests for substances that sportswomen and sportsmen are banned from taking. Oraqix may give a false positive test result for these substances.

Please talk to your dental practitioner or pharmacist about these possibilities if you think they may bother you.
