Be aware that some patients, during recovery from anesthesia, may experience some type of reaction thatcan vary in severity between pleasant states similar to sleep, vivid images, hallucinations, nightmares, and delirium (often with a sensation of being outside the body or floating). Sometimes, it may be accompanied by confusion, excitement, and irrational behavior, being remembered by some patients as an unpleasant experience. Normally, they only last a few hours, although, in some cases, they have recurred up to 24 hours after the operation has ended. It is not known that the use of ketamine causes any psychological sequelae. If necessary, your doctor will take the appropriate measures to reduce these reactions.

Uso a largo plazo

Ketolar is not indicated or recommended for long-term use.

There have been reports of urinary tract infections, sometimes accompanied by bleeding, and liver problems, particularly with long-term use (>3days) or drug abuse. See section 4 Possible adverse effects.

Abuso y dependencia de drogas

If used daily for several weeks, dependence and tolerance can develop, particularly in people with a history of drug abuse and dependence. Other adverse effects have also been reported: see "Long-term use".

Uso de Ketolar con otros medicamentos

Inform your doctor or pharmacist that you are using or have used recently or may need to use any other medication.

Certain medications may interact with each other. It is especially important to inform your doctor if you are taking any of the following medications:

• Barbiturates and/or opioid agonists
• Diazepam (a medication withsedative, tranquilizing, muscle-relaxing, and anticonvulsant effects)
• Neuromuscular blockers such as atracurium and tubocurarine
• Central nervous system depressants, such as ethanol, phenothiazines, H1 receptor antagonists, and muscle relaxants
• Medications for the treatment of anxiety and insomnia
• Halogenated anesthetics, thiopental (medications used for anesthesia)
• Thyroid hormones (medications used when the thyroid gland is not able to produce hormones in sufficient quantities)
• Antihypertensives (medications used in the treatment of high blood pressure)
• Sympathomimetics and vasopressin
• Ergometrine (vasoconstrictor)
• Theophylline and aminophylline(a medication used to dilate the bronchi)

Uso de Ketolar con los alimentos y bebidas

It is recommended that you do not eat or drink for at least 6 hours before anesthesia. Ketolar will normally be administered when your stomach is empty. However, Ketolar can still be used if, in an emergency, this is not possible.

Embarazo, lactancia y fertilidad

If you are pregnant or breastfeeding, or if you think you may be pregnant or plan to become pregnant, consultyour doctor or pharmacist before this medication is administered.

Embarazo

Ketamine easily crosses the placental barrier. There have been reports of newborns who, after receiving ketamine during delivery, have experienced respiratory problems and a low Apgar score, requiring resuscitation.

High doses of ketamine have caused elevated blood pressure and uterine tone in the mother. The safety of ketamine during pregnancy has not been established, so its use is not recommended.

Lactancia

The safe use of ketamine during breastfeeding has not been established, so its use is not recommended.

Conducción y uso de máquinas

Do not drive or operate machinery after receiving Ketolar, as this medication may affect your reaction time. Your doctor will indicate how long you should wait before driving or using machinery (usually 24 hours).

This medication will only be administered to you in a hospital by an anesthesiologist or an intensive care physician.

Ketolar is not indicated or recommended for long-term use.

Before the operation, you may be given other medications (to reduce saliva secretion or to reduce the risk of reactions during anesthesia recovery).

The dose you receive will depend on the type of intervention you are undergoing and varies from person to person.

When injected directly into a vein at a dose of 2 mg per kilogram of your body weight, Ketolar produces a state of unconsciousness in 30 seconds and the effect lasts 5 to 10 minutes. As it acts very quickly, it is essential to be lying down at the time of administration.

When administered in a muscle, at a dose of 10 mg per kilogram of your body weight, the anesthetic effect takes longer to appear (3-4 minutes), but lasts 12 to 25 minutes. Recovery of consciousness occurs gradually.

You should not leave the healthcare facility until you have fully recovered from the anesthesia. If you are discharged on the same day as the operation, you must be accompanied by another adult (See Driving and Use of Machines).

Use in children and adolescents

Intramuscular doses of 9-13 mg/kg typically produce a state of unconsciousness in 3-4 minutes after injection and the effect lasts 12 to 25 minutes.

Form of use and route of administration

Ketolarcan be administered by intramuscular or intravenous route.

Ketolar can be administered as a single anesthetic, as a complement to other general or local anesthetics, or also before administering other general anesthetics.

If more Ketolar than necessary is used

In case of overdose or accidental ingestion, contact your doctor or pharmacist immediately or the emergency service of your hospital. You can alsoconsult the Toxicological Information Service. Phone 91 562 04 20.

Ketolarhas a wide margin of safety. Several cases of accidental administration of up to 10 times the normally required dose have fully recovered, although it took them a long time to do so.

In case of Ketolaroverdose, or too rapid administration, respiratory depression may occur, requiring assisted ventilation, with mechanical ventilation being preferred.

If you have any other questions about the use of this medication, ask your doctor or pharmacist.

Instructions for Use and Handling for Healthcare Professionals

Ketolar should only be used in hospitals by, or under the supervision of, experienced or qualified medical doctors in the administration of general anesthetics as well as in the maintenance of respiratory pathways and in the control of respiration.

It is recommended to have a resuscitation equipment prepared for use.

It is recommended to administer the intravenous dose of ketamine over a period of about 60 seconds. A faster administration may cause respiratory depression or apnea and an increase in blood pressure response.

Single-dose packaging. After opening: From a microbiological point of view, the product should be used immediately unless the opening method prevents the risk of microbial contamination. Discard the unused product after opening.

Parenteral medications should be visually inspected to detect particles and discoloration before administration whenever the solution and packaging permit.

Keep the vial in the outer packaging to protect it from light. The color of the solution may vary from colorless to very slightly yellowish and may darken if exposed for a long time to the action of light. Although the darkening of the solution does not affect the potency of the medication, it should not be used if precipitation signs are observed.

Ketamine should not be mixed with barbiturates in the same syringe, as their chemical incompatibility leads to the formation of precipitates.

Ketamine should not be mixed with diazepam in the same syringe or infusion bottle. If it is desired to supplement the ketamine dose with diazepam, the two medications should be administered separately.
