Other medicines and Bunalict

Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines.

Some medicines can aggravate the side effects of Bunalict and in some cases can cause very serious reactions. Do not take any other medicines while you are taking Bunalict without talking to a doctor first, especially:

  • Concomitant use of Bunalict and sedatives or medicines for insomnia such as benzodiazepines or similar medicines increases the risk of drowsiness, difficulty breathing ( breathing depression ), coma and can be life-threatening. Due to this, concomitant use should only be considered when other treatment options are not possible. 
    If your doctor prescribes Bunalict at the same time as sedatives, the dose and treatment time should be limited by your doctor. Tell your doctor if you are taking any sedatives and carefully follow your doctor’s dose recommendations. It may be helpful to inform friends or relatives about paying attention to the signs and symptoms described above. Contact a doctor if you experience any of these symptoms.
  • Other medications that can make you feel sleepy are used to treat illnesses such as anxiety, insomnia, seizures, or pain. These types of medications reduce your alertness, which can make driving vehicles and using machines risky. They can also cause depression of the CNS ( central nervous system ), which is very serious. Below is a list of examples of these types of drugs:
    • other opioid-containing medications, e.g. methadone, some painkillers, and antitussives
    • antidepressants (used to treat depression), e.g. isocarboxazid, phenelzine, selegiline, tranylcypromine, and valproate, may potentiate the effects of this medicine
    • sedative H 1 receptor antagonists (used to treat allergic reactions), e.g. 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
  • Antiretroviral agents (used to treat HIV), e.g. ritonavir, nelfinavir, and indinavir, may prolong the effects of this medicine
  • Certain antifungals (used to treat fungal infections), e.g. ketoconazole, itraconazole, and certain antibiotics, may prolong the effects of this medicine
  • Some medicines may reduce the effect of Bunalict. They include medicines to treat epilepsy (eg carbamazepine and phenytoin ), as well as medicines to treat tuberculosis (rifampicin).
  • Naltrexone and nalmefene (medicines used to treat addiction) may counteract the therapeutic effects of Bunalict. They should not be taken with Bunalict treatment because you may then experience a sudden onset of prolonged and intense withdrawal symptoms.
