What is it and how is it used?

Medicinal product used in opioid dependence.

Suboxone is part of a medical, social and psychological treatment programme for patients addicted to opiate (narcotic) drugs. Treatment is prescribed and monitored by physicians who are specialists in the treatment of drug dependence.

Treatment with Suboxone sublingual tablets is intended for use in adults and adolescents over 15 years of age.


What do you have to consider before using it?

Do not take Suboxone

  • if you are allergic (hypersensitive) to buprenorphine, naloxone or any of the other ingredients of Suboxone,
  • if you have serious breathing problems,
  • if you have serious problems with your liver,
  • if you are intoxicated due to alcohol or have delirium tremens.

Take special care with SuboxoneMisuse and abuse
Some people have died from respiratory failure (inability to breathe) because they misused buprenorphine or took it in combination with other Central Nervous System depressants, such as alcohol, benzodiazepines (tranquilisers), or other opioids.

Cases of acute hepatic injury (liver problems) have been reported in a context of misuse, especially by intravenous route and at a high dose. These injuries could be due to special conditions as viral infections (chronic C hepatitis), alcohol abuse, anorexia, or medicines association (for example: antiretroviral nucleoside analogues, acetylsalicylic acid (aspirin), amiodarone, isoniazid, valproate). If you have symptoms of severe fatigue, itching, or if your skin or eyes look yellow, tell your doctor immediately, so that you can receive the proper treatment.

This product can cause withdrawal symptoms if you take it less than six hours after you use a narcotic (e.g. morphine, heroin) or less than 24 hours after you use methadone.

This product can cause sleepiness which may be increased by alcohol or anti-anxiety medicines.

Advise your physician in case of:

  • recent head injury or brain disease,
  • decrease of blood pressure,
  • in men: urinary disorders (especially linked to enlarged prostate).

This medicinal product may mask pain reflecting some diseases. Do not forget to advise your physician if you take this medicine.

This product may cause your blood pressure to drop suddenly, causing you to feel dizzy if you get up too quickly from sitting or lying down.

This product can cause dependence.

Athletes should be aware that this medicine, due to its active substance, may cause a positive reaction to ?anti-doping tests?.

Advise your physician in case of:

  • asthma or other breathing problems,
  • kidney disease,
  • liver disease.

Using other medicines
Using other medicines may increase the undesirable effects of buprenorphine and use of these medicines must be carefully monitored:

  • tranquilizers
  • anti-anxiety medicines
  • anti-depressants
  • benzodiazepines
  • some medicines used to treat high blood pressure.

If your physician prescribes benzodiazepines, you must not take more than the prescribed dose. Taking this product with benzodiazepines (medicines used to treat anxiety or sleep disorders) may cause death due to respiratory failure.

The following medicines may increase the buprenorphine blood concentrations, so concomitant use of these medicines together with Suboxone should be closely monitored and could require in some cases a dose reduction by your doctor:

  • anti-retrovirals (ritonavir, nelfinavir, indinavir)
  • ketoconazole
  • itraconazole

Please tell your doctor or pharmacist if you are taking or have recently taken any other medicines, including medicines obtained without a prescription.

Using Suboxone with food and drink

Do not take Suboxone together with alcoholic beverages as alcohol may possibly increase drowsiness induced by Suboxone.

You should not use Suboxone during pregnancy. Tell your doctor if you are pregnant or intend to become pregnant. He will decide if your treatment should be continued with an alternative medication.
