2 mg and 8 mg Freeze-dried tablet 

1. What Espranor is and what it is used for

Espranor freeze-dried tablet is a freeze-dried tablet that melts quickly on the tongue.

Espranor is used in adults and adolescents over the age of 15, as part of a medical, social, and psychological treatment program for addiction.

Espranor contains buprenorphine, which is a painkiller opioid (a narcotic). When used to treat patients who are addicted to opiates (drugs), e.g. morphine or heroin, it acts as a substitute for these drugs and thus helps the patient to be weaned from them over a period of time.

If treatment is stopped quickly, withdrawal symptoms may occur.

Espranor can not be replaced with other oral buprenorphine products and dose one of Espranor may differ from dose one of other buprenorphine products.
