Precautions
Caution is required as this medication can cause seizures if the recommended dosage is exceeded. Patients at risk of seizures or those with epilepsy should use it cautiously only when necessary. Long-term use of this medication can lead to psychological and physical dependence, so it should be administered under strict supervision for patients at risk of drug abuse. When taken with central nervous system depressants or alcohol, severe sedation, respiratory depression, and coma may occur, so it should be used with extreme caution in such cases. Patients with specific genetic characteristics that metabolize the drug faster are at increased risk of respiratory depression and require dose adjustment and monitoring. It should not be administered to children under 12 or adolescents under 18 who have undergone tonsillectomy and adenoidectomy, and even when necessary in this age group, extreme caution should be exercised. The ampoule injection should be handled carefully as glass fragments may be mixed in when breaking the container, particularly when administering to children or the elderly.

Drowsiness, dizziness, and other symptoms may occur during administration, so driving or operating dangerous machinery should be avoided, and caution is needed in assessing conditions in patients with acute abdominal diseases. In case of overdose, severe respiratory depression and seizures may occur, necessitating immediate emergency treatment, and naloxone can be used as an antidote. This medication interacts with various drugs, so it is essential to consult with a specialist when used in combination with other medications, especially central nervous system depressants, MAO inhibitors, and antidepressants. It is safer not to use this medication during pregnancy or breastfeeding, as it may transmit to the infant through breast milk and pose a risk.
