1. What is Torecan and what is it used for
Torecan belongs to a group of phenothiazine derivatives. The medicine affects the structures in the brainstem that regulate physiological processes related to vomiting. In this way, it inhibits the body's reaction to stimuli that induce nausea and vomiting.
The medicine is intended for the treatment of nausea and vomiting in the following conditions:
- after anticancer chemotherapy,
- after radiotherapy,
- after the use of emetic drugs,
- after surgical procedures.
2. Important information before using Torecan
When not to use Torecan
- if you are allergic to thiethylperazine, phenothiazines, or any of the other ingredients of this medicine (listed in section 6);
- in severe disturbances of consciousness or other symptoms of impaired central nervous system function;
- if you have very low blood pressure;
- if you are pregnant or breastfeeding.
Torecan should not be used in children under 15 years of age and in children and adolescents with symptoms similar to those of Reye's syndrome (a rare but serious condition that causes swelling in the liver and brain).
Warnings and precautions
Before starting treatment with Torecan, discuss with your doctor if you have:
- low blood pressure;
- pregnancy, especially if you have a history of high blood pressure with swelling of the limbs (pre-eclampsia);
- liver function disorders;
- a history of involuntary body movements;
- are taking bromocriptine.
Like other antiemetic medicines, Torecan may mask the symptoms of certain gastrointestinal and central nervous system disorders, as well as the adverse effects of other medicines.
Torecan, as a representative of the phenothiazine group, may cause the occurrence of a group of symptoms known as malignant neuroleptic syndrome, which is characterized by high fever, muscle stiffness, changes in mental state, and fluctuations in blood pressure. In such cases, treatment should be discontinued immediately and a doctor should be informed as soon as possible.
In elderly patients, involuntary movements may occur during treatment with Torecan, therefore, treatment should not last more than 2 months.
Torecan should never be administered intrarterially.
Torecan and other medicines
Tell your doctor or pharmacist about all medicines you are taking or have recently taken, as well as any medicines you plan to take.
Taking Torecan with certain other medicines may lead to interactions between them, which may reduce or increase the effect of each medicine.
Your doctor should be informed, especially if you are taking:
- medicines that act on the central nervous system (sedatives, opioid analgesics, tranquilizers, antidepressants),
- medicines that inhibit the secretion of certain hormones (bromocriptine),
- medicines used in the treatment of cancer (procarbazine).
Pregnancy, breastfeeding, and fertility
If you are pregnant or breastfeeding, think you may be pregnant, or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.
Pregnancy
There is limited data on the use of thiethylperazine in pregnant women. Animal studies are insufficient to exclude teratogenic effects of thiethylperazine, especially since two observational studies suggested a possible association. As a precautionary measure, Torecan should not be used during pregnancy.
Breastfeeding
Phenothiazines pass into breast milk, therefore, Torecan should not be used during breastfeeding.
Fertility
Thiethylperazine had no effect on fertility in male rats. The effect on the pregnancy rate in female rats observed only at doses higher than recommended indicates little clinical significance.
Driving and using machines
Do not drive vehicles or operate machines while using Torecan solution for injection.
Torecan may significantly impair your ability to drive vehicles and operate machines, especially when used with sedatives, hypnotics, or alcohol. Therefore, caution is advised when driving vehicles and operating machines.
Torecan contains sorbitol (E420), sodium metabisulfite (E223), and sodium.
If you have previously been diagnosed with an intolerance to some sugars, you should consult your doctor before taking the medicine.
The medicine may rarely cause severe allergic reactions and bronchospasm.
This medicine contains less than 1 mmol of sodium (23 mg) per dose, i.e., the medicine is considered "sodium-free".
3. How to use Torecan
This medicine will be administered by a doctor or nurse.
The daily dose is one to three ampoules.
