To avoid precipitated opioid withdrawal, it is recommended you should have an opioid-free interval of a minimum of 7 to 10 days if previously dependent on short-acting opioids. Patients transitioning from buprenorphine or methadone may be vulnerable to precipitation of withdrawal symptoms for as long as two weeks. Acamprosate and naltrexone what does laced weed look like are two different medications that are used in the treatment of alcohol use disorder. They work in different ways to help people who are dependent on alcohol to abstain from drinking it. Naltrexone is also used for the treatment of opioid use disorder. Naltrexone is a pure opiate antagonist and blocks opiate receptors in the body.

Side Effects

In conclusion, the findings of the SWIFT trial represent a significant step forward in the treatment of OUD with XR-naltrexone. However, the training of providers in managing safety concerns highlighted in the study must be addressed to ensure that this approach can be implemented effectively and safely. By balancing the benefits of rapid initiation with comprehensive safety measures, we can make meaningful progress in combating the opioid epidemic and improving outcomes for individuals with OUD. Naltrexone is used as an adjunct to social and psychotherapy in the treatment of opioid and alcohol addiction.

What happens if you drink alcohol while taking naltrexone?

Low doses of alcohol stimulate the glutamate system, which enhances dopaminergic activity and leads to arousal and increased energy. In contrast, higher doses of alcohol inhibit glutamate and augment GABA neurotransmission, suppressing dopaminergic activity and leading to sedation, among other effects. These pathways are further modulated by endogenous opioid-like protein neurotransmitters, enkephalins and β-endorphin (Fig. 1). Such “endogenous opioids” are thought to be released during alcohol intoxication and may contribute to alcohol addiction by inhibiting GABA pathways and enhancing dopaminergic signaling. Nausea, headaches and tiredness are the most common side effects I hear about from patients taking naltrexone.
