Hidrochloride of bupivacaine / Adrenaline

Read this leaflet carefully before starting to use the medicine, as it contains important information for you

• Keep this leaflet, as you may need to read it again.
• If you have any doubts, consult your doctor, pharmacist or nurse.
• This medicine has been prescribed only for you, and you must not give it to others even if they have the same symptoms as you, as it may harm them.
• If you experience any side effects, consult your doctor, pharmacist or nurse, even if they are not listed in this leaflet. See section 4.

This medication contains hydrochloride of bupivacaína, a local anesthetic(agent that reduces or eliminates sensations, affecting a particular region) thatbelongs to the subgroup of amides, and adrenaline, a vasoconstrictor agent that narrows blood vessels,reducing blood flow in the area where the doctor injects the needle (local anesthesia), prolonging the effect of the anesthesia in the injection site.

You have been prescribed to provide you with anesthetic effect.

Do not use Bupivacaína/Adrenalina Physan 2,5 mg/ml + 0,005 mg/ml:

• If you are allergic to hydrochloride of bupivacaína, to adrenaline or to any of the other components of Bupivacaína/Adrenalina Physan 2,5 mg/ml + 0,005 mg/ml (listed in section 6).
• If you are allergic to any other local anesthetic of the same group (for example, articaine, mepivacaína, lidocaína or prilocaína).
• If it is used as intravenous regional anesthesia (Bier block), since the inadvertent passage of bupivacaína into the bloodstream may lead to acute systemic toxicity reactions.
• If you have any of the following conditions, do not perform an epidural anesthesia:

• Pre-existing central nervous system disease attributable to infection, tumors or other causes.
• Spinal deformity and active disease (e.g. spondylitis, tumor, tuberculosis) or recent injury (e.g. fracture) of the vertebral column.
• Skin infection at the injection site or in a nearby position.
• Cardiovascular disease, especially heart block or hypovolemic shock.
• Coagulation disorders or ongoing anticoagulant treatment.

Warnings and precautions

Consult your doctor before starting to use Bupivacaína/Adrenalina Physan 2,5 mg/ml + 0,005 mg/ml:

• If you have any type of heart block
• If you have arrhythmias
• If you have low blood pressure
• If you have hemorrhage
• If you have any type of infection
• If you have liver or kidney disorders
• If you have severe or untreated high blood pressure
• If you have uncontrolled thyroid disease
• If you have cerebral circulation disorders
• If you have advanced diabetes

Children

Bupivacaína should be used with caution in children aged 1 to 12 years, as they have a higher risk of systemic toxicity.

Other medications and Bupivacaína/Adrenalina Physan 2,5 mg/ml + 0,005 mg/ml

Pregnancy and breastfeeding

If you are pregnant or breastfeeding, or think you may be pregnant, consult your doctor or pharmacist before using this medication.

Pregnancy

Your doctor will prescribe Bupivacaína/Adrenalina Physan 2,5 mg/ml + 0,005 mg/ml taking into account the benefit it may have over the risk to your baby.

Breastfeeding

Bupivacaína is excreted in breast milk, but at therapeutic doses of this medication, no effects are expected in breastfed infants. There is insufficient information available regarding the excretion of adrenaline in breast milk, but it is unlikely to affect the infant.

Driving and operating machinery

Bupivacaína/Adrenalina Physan 2,5 mg/ml + 0,005 mg/ml may temporarily impair your ability to move, attention and coordination. Your doctor will indicate if you can drive or operate machinery.

Bupivacaína/Adrenalina Physan 2,5 mg/ml + 0,005 mg/ml contains metabisulfito de sodio and sodium

This medication may cause severe allergic reactions and bronchospasm (sudden feeling of choking) because it contains metabisulfito de sodio.

This medication contains 32.8 mg of sodium (main component of table salt/for cooking) per 10 ml ampoule. This is equivalent to 1.64% of the maximum daily sodium intake recommended for an adult.

This medication should only be administered under the supervision of a doctor with experience in the use of this type of medication.

Bupivacaína/Adrenalina Physan 2,5 mg/ml + 0,005 mg/ml is administered as an injection through infiltration, subcutaneously, intramuscularly, epidurally, intraarticularly, perineurally, and periosseously.

The dose, rate of administration, and duration of treatment will vary depending on the anesthetic procedure being performed, the area to be anesthetized, and the patient's weight, clinical condition, and response.

If more Bupivacaína/Adrenalina Physan 2,5 mg/ml + 0,005 mg/ml is administered than prescribed

Similar to other local anesthetics, due to excessive dosing, rapid absorption, or accidental injection into blood vessels, symptoms of intoxication may occur, which may manifest as:

• On the central nervous system:

Characterized by tingling, tongue numbness, mild drowsiness, ringing in the ears, blurred vision, and muscle tremors. Convulsions and loss of consciousness may follow, followed by breathing difficulties.

• On the cardiovascular system:

Low blood pressure (hypotension),

Decreased heart rate, arrhythmia, and cardiac arrest.

If toxic effects occur, the first measure is to stop administering the local anesthetic. Subsequent treatment involves stopping convulsions and ensuring adequate breathing with oxygen, if necessary through assisted respiration. If convulsions occur, they can be treated with100 -150 mg of thiopental i.v or 5 - 10 mg of diazepami.v. If hypotension occurs, a vasopressor should be administered intravenously, for example 5 - 10 mg of ephedrine. If cardiac arrest occurs, cardiopulmonary resuscitation should be applied immediately and a dose of 0.1 – 0.2 mg of adrenaline should be administered as soon as possible via intravenous or intracardiac route. If cardiac arrest occurs, prolonged resuscitation efforts should be applied.

In case of overdose or accidental administration, consult your doctor or pharmacist immediately or call the Toxicological Information Service, phone 91 562 04 20, indicating the medication and the amount administered.

This information is intended solely for doctors or healthcare professionals

The solutions must be used immediately after opening. Any remaining solution must be discarded.

Due to the instability of adrenaline, products containing it should not be sterilized.

Appropriate precautions must be taken to avoid prolonged contact between anesthetic solutions containing adrenaline (low pH) and metal surfaces (e.g. needles and metal parts of syringes), as metal ions dissolve, mainly copper ions, which can causelocal irritation (swelling, edema) at the injection site and accelerated degradation of adrenaline).

Precautions must be taken to prevent acute toxicity reactions, avoiding intravascular injection. It is recommended to perform aspiration before and during administration. When administering high doses, for example in the case of epidural block, it is advisable to perform a test dose with 3-5 ml of bupivacaine with epinephrine. An accidental intravascular injection can be detected by a temporary increase in heart rate. The maximum dose should be administered very slowly, at a rate of 25-50 mg/min, or in increments of dose, maintaining constant verbal contact with the patient. If symptoms of toxicity appear, administration should be stopped immediately.

Regional or local anesthesia processes, except for trivial ones, must always be carried out by properly trained professionals and in areas with immediate access to resuscitation equipment and medications. When major blocks are performed, a previously inserted intravascular catheter should be inserted at the injection site of the local anesthetic. Doctors should receive adequate training according to the process they must perform and be familiar with the diagnosis and treatment of side effects, systemic toxicity, and other complications.

In any case, and taking into account that the dosage should be calculated based on several factors, we recommend consulting the information provided in the Technical Data Sheet before using this medicine.

Incompatibilities

Bupivacaine has limited solubility at a pH above 6.5. This should be taken into account in the case of adding alkaline solutions, for example carbonates, as precipitation may occur. Containing adrenaline, the mixture with alkaline solutions leads to rapid degradation of the same.
