1. What Carbocaine is and what it is used for

Carbocaine contains the active substance mepivacaine hydrochloride, which is a local anesthetic. It temporarily blocks the nerve signals in the area where it is injected.

Carbocaine is used to temporarily reduce or remove the sensation in a part of the body.

Mepivacaine hydrochloride contained in Carbocaine may also be approved for the treatment of other conditions not mentioned in this product information. Ask your doctor, pharmacist, or other healthcare professional if you have any further questions and always follow their instructions.

2. What you need to know before you are given Carbocaine

Carbocaine should not be given:

  • if you are allergic to mepivacaine hydrochloride or any of the other ingredients of this medicine (listed in section 6)
  • if you are allergic to other local anesthetics belonging to the same group (eg bupivacaine, lidocaine )
  • as back anesthesia (epidural anesthesia) if you are in severe shock (ie have extremely low blood pressure, eg in severe heart problems or large blood or fluid losses).

Warnings and cautions

Talk to your doctor or nurse before giving Carbocaine:

  • if you are older or have a reduced general condition

  • if you are being treated with antiarrhythmic drugs
  • if you have severe liver disease
  • if you have severe renal impairment
  • if you have acute porphyria (a hereditary disease that affects the nervous system)

The doctor will be observant of any side effects that may occur in connection with the medicine being given in the eye or as a spinal anesthetic (epidural anesthesia).


Carbocaine should not be given to newborns and infants under 6 weeks of age, as their liver has a harder time breaking down the drug.

For the treatment of small children over 6 weeks of age, no data are available and the doctor must therefore be especially careful.

Other drugs and Carbocaine

Carbocaine can affect or be affected by other drugs, such as:

  • other local anesthetics
  • drugs for arrhythmias in the heart

Driving and using machines

Depending on the dose you receive and how it is given, Carbocaine can have a transient effect on your mobility, coordination, and attention.

You are responsible for assessing whether you are fit to drive a motor vehicle or perform work that requires sharpened attention. One of the factors that can affect your ability in these respects is the use of drugs due to their effects and/or side effects. Descriptions of these effects and side effects can be found in other sections. Read all the information in this leaflet for guidance. If you are not sure, talk to your doctor or pharmacist.

3. How Carbocaine is given

You will receive the medicine from a doctor or nurse, in the form of an injection. Dose one of Carbocaine is determined by your doctor and depends on the type of anesthesia you need, the area to be anesthetized, and the duration of the anesthesia. The doctor adjusts the dose to your age, weight, and general health and uses the lowest possible dose that provides adequate anesthesia.

Use for children

Carbocaine should not be given to newborns and infants under 6 weeks of age. For children between 6 weeks of age and 12 years of age, the doctor calculates the appropriate dose based on the patient’s weight.

If you take more Carbocaine than you should

If you think you have been given too much medicine, tell your doctor or nurse immediately.

In case of overdose, poisoning reactions can occur, usually within 15‑60 minutes. If Carbocaine is accidentally injected into a blood vessel, intoxication reactions may occur immediately (within seconds or minutes). The reactions mainly affect the central nervous system and the cardiovascular system. The first symptoms are usually a feeling of intoxication, numbness around the mouth and in the tongue, visual disturbances, tinnitus, and sensitivity to sound. Then you may have more severe symptoms, such as difficulty speaking clearly, muscle twitching or shaking, and finally cramps and unconsciousness. In addition, you may have difficulty breathing. In severe cases, you can get a drop in blood pressure, slow heart rate, irregular heartbeat, and even cardiac arrest and respiratory arrest. Such reactions must be treated immediately. Therefore, your doctor always makes sure that there is resuscitation equipment nearby when using Carbocaine.

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