SCANDONEST 3% Plain 2.2ml is a Prescription Medicines only administered by a dentist. Scandonest 3% Plain : Mepivacine hydrochloride 3% (30mg/mL), Injection. SCANDONEST 3% is indicated for the production of local anaesthesia in routine dental procedures and oral surgery by means of infiltration and nerve block techniques.
CONTRAINDICATIONS: These include : a) contraindications to Mepivacaine: - specific allergies to Mepivacaine or to other anaesthetics of amide type, - allergies of cross type Procaine – Mepivacaine. b) injection by intravenous route is strictly contra-indicated c) inflammation or sepsis in the region of the proposed injection d) hypersensitivity to any other component e) patients receiving monoamine oxidase inhibitors (or who have received such an agent within two weeks) or tricyclic antidepressants.
Special warnings and precautions for use: General precautions:- WHEN ANY LOCAL ANAESTHETIC AGENT IS USED, RESUSCITATIVE EQUIPMENT AND DRUGS, INCLUDING OXYGEN, SHOULD BE IMMEDIATELY AVAILABLE IN ORDER TO MANAGE POSSIBLE ADVERSE REACTIONS INVOLVING THE CARDIOVASCULAR, RESPIRATORY OR CENTRAL NERVOUS SYSTEMS. BECAUSE OF THE POSSIBILITY OF HYPOTENSION AND BRADYCARDIA FOLLOWING MAJOR BLOCKS, AN IV CANNULA SHOULD BE INSERTED BEFORE THE LOCAL ANAESTHETIC IS INJECTED. DELAY IN PROPER
MANAGEMENT OF DOSE-RELATED TOXICITY, UNDER VENTILATION FROM ANY CAUSE AND/OR ALTERED SENSITIVITY MAY LEAD TO THE DEVELOPMENT OF ACIDOSIS, CARDIAC ARREST AND DEATH.- INJECTION SHOULD ALWAYS BE MADE SLOWLY WITH FREQUENT ASPIRATIONS TO AVOID INADVERTENT INTRAVASCULAR INJECTION, WHICH CAN PRODUCE CEREBRAL SYMPTOMS EVEN AT LOW DOSES.- Note, that the absence of blood in the syringe does not assure that intravascular injection will be avoided. There should be careful monitoring of cardiovascular and respiratory vital signs after each injection.
- Intra-vascular injection is strictly contra-indicated. An accidental injection into a blood vessel may be associated with systemic adverse effects due to the circulating levels of adrenaline and mepivacaine. Therefore, it is imperative to ensure that the needle being used for the injection does not go into a vessel.
- Since amide-type local anaesthetics are also metabolised by the liver and excreted via kidneys, SCANDONEST 3% Plain should be used with caution in patients with hepatic or renal disease.
- Many drugs used during the conduct of anaesthesia are considered potential triggering agents for familial malignant hyperthermia, since it is not known whether amide-type local anaesthetics may trigger this reaction, and since the need for supplemental general anaesthesia cannot be predicted in advance, it is suggested that a standard protocol for management should be available.
Interaction with other medicines and other forms of interaction: The administration of local anaesthetic solutions containing adrenaline to patients receiving monoamine oxidase inhibitors, tricyclic antidepressants or phenothiazines may produce severe prolonged hypotension or hypertension.
Fertility, pregnancy and lactation: Use in pregnancy (Category A) – Drugs which have been taken by a large number of pregnant women and women of childbearing age without any proven increase in the frequency of malformations or other direct or indirect harmful effects on the foetus having been observed.): The safe use of Mepivacaine during pregnancy has not been established. Mepivacaine has however been used extensively for dental procedure during pregnancy with no proven increase in frequency of malformations or of harmful effects to mother or foetus.
Use in lactation: It is not known whether mepivacaine or its metabolites appear in breast milk. Therefore the use of SCANDONEST 3% Plain is not recommended during lactation.
Dose:
The lowest dosage that results in effective anaesthesia for the planned treatment should be used. The dosage will depend upon the area of the oral cavity to be anaesthetised, the vascularity of the oral tissues and the technique of anaesthesia

Adolescents between 14 and 17 years : usual dosage one cartridge (2.2 mL). Do not exceed 2 cartridges (4.4 mL) in general cases.
Children between 6 and 14 years : usual dose is 1.35 mL. Do not exceed 2.7 mL in usual cases.
Children between 3 and 6 years : do not exceed maximum recommended dose of 1.8 mL.
