🔔 Why is this medication prescribed?

Buprenorphine extended-release injection is used to treat opioid dependence (addiction to opioid drugs, including heroin and narcotic painkillers) in people who have received buccal or sublingual buprenorphine for at least 7 days. Buprenorphine extended-release injection is in a class of medications called opiate partial agonists. It works to prevent withdrawal symptoms when someone stops taking opioid drugs by producing similar effects to these drugs.

🔔 How should this medicine be used?

Buprenorphine extended-release (long-acting) injection comes as a solution (liquid) to be injected subcutaneously (just under the skin) by a health care provider into the stomach area. It is usually given once monthly with at least 26 days in between doses. Each buprenorphine injection slowly releases the drug into your body over a month.

After you receive a dose of buprenorphine extended-release injection, you may notice a lump at the injection site for several weeks, but it should decrease in size over time. Do not rub or massage the injection site. Be sure that your belt or waistband does not put pressure on the place where the medication was injected.

Administrative spending is particularly problematic in United States hospitals, where it makes up about 25% of total hospital spending and accounts for hundreds of billions of dollars in healthcare spending annually, The Commonwealth Fund The percentage of total hospital spending devoted to administration is highest in for-profit hospitals, followed by nonprofit hospitals, teaching hospitals, and finally public hospitals. Outdated reimbursement and reporting methods are a big part of the administrative cost, says Salvo-Wendt. “Reimbursing in bundled payments instead of itemizing each service or component would produce instant savings of administrative costs.”

Your doctor may increase or decrease your dose depending on how well the medication works for you, and any side effects you experience. Be sure to tell your doctor how you are feeling during your treatment with buprenorphine extended-release injection.

If buprenorphine extended-release is to be discontinued, your doctor will probably decrease your dose gradually. You may experience withdrawal symptoms including restlessness, teary eyes, sweating, chills, widening of the pupils (black circles in the middle of the eyes), irritability, anxiety, backache, weakness, stomach cramps, difficulty falling asleep or staying asleep, nausea, loss of appetite, vomiting, diarrhea, fast breathing, or fast heartbeat. These withdrawal symptoms may occur 1 month or longer after your last buprenorphine extended-release injection dose.
