2. What you need to know before you use Lidonostrum
Do not take Lidonostrum:
If you are hypersensitive to lidocaine or any of the other ingredients of this medicine (listed in section 6).
Warnings and precautions
Talk to your doctor, pharmacist or nurse before using Lidonostrum.
The absorption through injured skin surfaces and mucosae is relatively high, particularly at bronchi level. This must be considered especially when the ointment is used in children for the treatment of large areas.
The oropharyngeal use of topical anaesthetic agents may interfere with swallowing and thus the danger of aspiration is justified. This is particularly important in children.
Avoid contact with the eyes.
Other medicines and Lidonostrum
Tell your doctor or pharmacist if you are using, have recently used or might use any other medicines.
Lidocaine must be used with caution in patients receiving antiarrhythmic drugs such as tocainide, since toxic effects are additive.
Lidonostrum with food, drink and alcohol
Pregnancy, breast-feeding and fertility
If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before using this medicine.
Lidocaine crosses the placenta and so its use is not recommended, particularly during the first 3 months of pregnancy.
Lidocaine reaches the mother’s milk but in such small amounts that, when used in therapeutic doses, there is no risk of affecting the baby.
Driving and using machines
Lidocaine may temporarily affect coordination and locomotion. Lidonostrum contains 250 mg of propylene glycol for each gram of ointment.
3. How to use Lidonostrum
Always use this medicine exactly as your doctor, pharmacist or nurse has told you. Check with your doctor, pharmacist or nurse if you are not sure.
As with other local anaesthetic adverse reactions and complications may be easily avoided if the minimum effective dose is used.
In debilitated patients, elderly and children the doses must be adapted to age and physical condition.
The ointment must be applied in a thin layer for an adequate control of the symptoms.
For endotracheal intubation apply directly on the tube.
In stomatology apply in the oral mucosa previously dried. Let the ointment act for at least 3-5 minutes in order to obtain the effect.
In sore nipple apply with the help of a small gauze. The ointment must be removed prior to breast-feeding.
Do not apply more than 20 g of ointment within 24h.
If you use more Lidonostrum than you should
The treatment of a patient with toxicity signs must ensure adequate ventilation. If seizures occur, these can be treated with intravenous administration of diazepam or thiopental. If ventricular fibrillation or cardiac arrest occurs proceed to cardiovascular resuscitation. Adrenaline in repeated doses and sodium bicarbonate must be administered as soon as possible.
If you forget to use Lidonostrum
Do not apply a double dose to make up for a forgotten dose.
If you stop using Lidonostrum
If you have any further questions on the use of this medicine, ask your doctor, pharmacist or nurse.
4. Possible side effects
Like all medicines, this medicine can cause side effects, although not everybody gets them.
In some rare cases, local anaesthetics have been associated to allergic reactions (including severe anaphylactic shock).
Systemic adverse reactions are extremely rare and may occur due to high serum levels that may have been caused by excessive dosing, fast absorption or hypersensitivity, idiosyncrasy or reduced tolerance from the patient. Such reactions are systemic and involve the central nervous system and/or the cardiovascular system.
Reactions at central nervous system level are excitatory and/or depressive and can be characterized by anxiety, dizziness, seizures, unconsciousness and possibility of respiratory arrest. Excitatory reactions can be very quick or may not even occur. In this case, the first manifestation of toxicity is characterized by drowsiness. Cardiovascular reactions are depressive and can be characterized by hypotension, myocardial depression, bradycardia and the possibility of cardiac arrest.
