What Xylocaine Viscous is and what it is used for

Xylocaine Viscous is a local anesthetic. The solution is intended to be rinsed around the mouth and/or swallowed and then produces an analgesic effect in the mouth and/or upper gastrointestinal tract.

Xylocaine Viscous is intended for the treatment of adults in the following situations:

  • in painful disease conditions in the mouth, throat, and esophagus
  • by healthcare personnel in connection with the introduction of catheters, probes, or examination instruments into the stomach.

What you need to know before using Xylocaine Viscous

Do not use Xylocaine Viscous

  • if you are allergic to local anesthetics, para-aminobenzoic acid (PABA), or any of the other ingredients of this medicine (listed in section 6).

Warnings and precautions

Use of Xylocaine Viscous in the throat can affect the ability to swallow and thus increase the risk of involuntarily getting Xylocaine Viscous in the trachea. The anesthesia can also increase the risk of bite injuries. Before taking food and drink, the anesthesia should therefore have completely worn off.

Talk to your doctor before you start using Xylocaine Viscous if you suffer from a disorder of the heart’s conduction system (heart block), severe liver disease, severely reduced kidney function, porphyria (hereditary metabolic disorder), or a generally impaired general condition.

Other medicines and Xylocaine Viscous

Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines.

The risk of side effects increases if you use Xylocaine Viscous at the same time as certain other medicines, above all

  • other local anesthetics
  • drugs against irregular heart activity (so-called antiarrhythmics )

Treating doctors, therefore, need to be aware of other concomitant medications.

Pregnancy and breastfeeding

If you are pregnant or breastfeeding, think you may be pregnant, or are planning to have a baby, ask your doctor or pharmacist for advice before using this medicine.

Temporary use of Xylocaine Viscous during pregnancy is unlikely to cause any adverse effects on the fetus.

Lidocaine passes into breast milk but is unlikely to affect children who are breastfed.

Driving ability and use of machinery

When treated with Xylocaine Viscous, the ability to react is not affected.

Xylocaine Viscous contains preservatives

Xylocaine Viscous contains the preservatives methyl parahydroxybenzoate and propyl parahydroxybenzoate. These can give rise to an allergic reaction (possibly delayed).

How to use Xylocaine Viscous

Always use this medicine as directed by your doctor. Ask your doctor or pharmacist if you are unsure.

Your doctor will determine the dose that is right for you.

The total dose in one day should not exceed a total of 60 ml.

If you have used too much Xylocaine Viscous

If you have ingested too large a dose of medicine or if, for example, a child has ingested the medicine by mistake, always contact a doctor or hospital for an assessment of the risk and advice.

Possible side effects

Like all medicines, this medicine can cause side effects, although not everybody gets them.

Rare (affects less than 1 in 1,000 users): Allergic reactions, in the most severe cases anaphylactic shock (severe allergic reaction with, for example, rash, swelling, fever, difficulty breathing, and fainting). If you experience such severe allergic reactions, you should seek emergency care immediately.

How Xylocaine Viscous should be stored

Keep this medicine out of the sight and reach of children.

Use before the expiry date stated on the packaging. The expiration date is the last day of the specified month.

Medicines must not be thrown into the drain or among the household waste. Ask the pharmacist how to dispose of medicines that are no longer used. These measures will help to protect the environment.
