Opioid Substitution Therapy (OST):
Medications like buprenorphine, methadone, and morphine bind to the opioid receptors and stop the withdrawal symptoms and cravings. These medications are known as Opioid Substitution Therapies or OST for short. If you have developed a dependence on short-acting opioids, such as heroin, you will get sick about 6-8 hours after you last used. However, OST is longacting and buprenorphine and methadone both work for at least 24 hours. With the right dose, someone with opioid dependence will usually only need to take OST once a day and with the new long acting depot buprenorphine only once per week or per month.
OST is a life-saving medication that takes you away from the challenges of raising money and the risk of going into withdrawals. It also reduces your risk from viruses like HIV and hepatitis and your vulnerability to opioid overdose and police arrest.
