Other medicines and Temgesic solutions for injection
Some medicines can increase the side effects of Temgesic solution for injection and in some cases can cause very serious reactions. Tell your doctor if you are taking, have recently taken, or might take any other medicines. Do not take any other medicines while using Temgesic solution for injection without first talking to your doctor, especially:
- Antidepressants such as moclobemide, tranylcypromine, citalopram, escitalopram, fluoxetine, fluvoxamine, paroxetine, sertraline, duloxetine, venlafaxine, amitriptyline, doxepin or trimipramine. These medicines can affect or be affected by Temgesic solution for injection and you may have symptoms such as involuntary rhythmic muscle twitching, including in the muscles that control eye movements, agitation, hallucinations, coma, profuse sweating, tremors, increased reflexes, tense muscles and body temperature above 38°C. Contact the doctor if you experience such symptoms.
- Benzodiazepines (used to treat anxiety and sleep disorders), eg diazepam, temazepam, or alprazolam. If you use Temgesic solution for injection at the same time as sedatives such as benzodiazepines or similar medicines, it can increase the risk of drowsiness, breathing difficulties, and coma, and it can be life-threatening. Concurrent treatment should therefore only be considered if there are no other treatment options. However, if the doctor prescribes Temgesic together with sedative drugs, the doctor must limit the dose and the duration of treatment. Inform the doctor about all sedatives you are taking and follow the doctor’s prescription very carefully. It may be helpful to inform family and friends that they should be aware of the signs and symptoms described above. Contact the doctor if you experience any such symptoms.
- Other medicines that can make you feel sleepy are used to treat conditions such as anxiety, insomnia, convulsions/seizures, or pain. These types of drugs reduce your level of alertness, which can make it difficult to drive and use machines. They can also cause central nervous system depression, which is very serious. Below is a list of examples of these types of drugs:
- Other opioid-containing medications, e.g. methadone, certain pain relievers, and cough suppressants.
- Antidepressants (used to treat depression), e.g. isocarboxazid, phenelzine, selegiline, tranylcypromine, and valproate, may enhance the effects of this drug.
- Sedative H 1 -receptor antagonists (used to treat allergic reactions), eg diphenhydramine and chlorphenamine.
- Barbiturates (used to induce sleep or sedation ), e.g. phenobarbital and secobarbital.
- Sedatives (used to induce sleep or sedation ), e.g. chloral hydrate.
- Clonidine (used to treat high blood pressure ) may prolong the effects of this medicine.
- Naltrexone can counteract the therapeutic effects of Temgesic solution for injection. If you take this medicine and then take naltrexone at the same time, you may experience a sudden onset of prolonged and intense withdrawal symptoms.
- Antiretroviral drugs (used against HIV infection ), e.g. ritonavir, nelfinavir, and indinavir, may increase the effects of this medicine.
- Some antifungals (used to treat fungal infections), e.g. ketoconazole, itraconazole, and certain antibiotics ( macrolides ), may prolong the effects of this medicine.
- Some medicines can reduce the effect of Temgesic solution for injection. These include drugs for the treatment of epilepsy (e.g. carbamazepine and phenytoin ), as well as drugs for the treatment of tuberculosis (rifampicin).
- Anesthetics (used in surgery such as halothane).
