How Long Does Naltrexone Last?

Are you considering taking Naltrexone to help with an addiction or recovery journey? If so, understanding how long the effects of Naltrexone and how long it remains in your system is key.

In this blog post, we’ll take a closer look at the timeframe for Naltrexone’s effects and when it leaves your body. We'll also discuss what factors influence its duration and other tips concerning the safety usage of the drug.

What Is Naltrexone?

Naltrexone, an opioid antagonist, serves a crucial role in the management of opioid and alcohol use disorders (AUD). This medication works by blocking the opioid receptors in the brain, effectively reducing the desired effects of these substances and assisting in addiction treatment.

Available in either a daily tablet or a monthly injection form, naltrexone provides flexibility in its administration. The standard dosage of this medication is 50 mg per day. Depending on your healthcare provider's assessment, you may be prescribed one of these dosages: a daily 50 mg tablet, two 100 mg tablets every other day, or three 150 mg tablets every third day.

For those opting for the injection, it is delivered as an extended-release version containing 380 mg of naltrexone. This method ensures a consistent level of medication throughout the month.

Through its effects of blocking opioid receptors and reducing the appeal of substance use, naltrexone serves as a vital tool in the treatment of opioids and AUDs.

What Is the Duration of Action of Naltrexone? How Long Does Naltrexone Last?

The duration of the naltrexone treatment depends on its form of application. When taken orally, naltrexone lasts for a period between 24 and 72 hours.

Specifically, a 50 mg dose of naltrexone provides opioid-blocking effects for 24 hours, while increasing the dosage to 150 mg extends how long naltrexone stays in your system up to 72 hours. 

For a longer-lasting effect, naltrexone injections are used, which remain effective for about a month.

Is Naltrexone Long Lasting?

The longevity of naltrexone in your system is contingent on the dose and method of administration. As mentioned, oral naltrexone, for instance, can be effective around 24 to 72 hours after administration. On the other hand, the injection form works for up to a month.

In both cases, however, naltrexone will last depending on several factors like biological differences, liver health, faster metabolism, and other individual factors.

Does Naltrexone Work Immediately?

Naltrexone, a medication used to treat various conditions, including addiction, begins to take effect fairly quickly. When administered orally, it starts operating within an hour of consumption, gradually exerting its therapeutic effects.

On the other hand, if you opt for the injectable form, the peak effects are felt approximately 2 hours post-injection, with another peak occurring between 48 to 72 hours after administration. This dual peak phenomenon allows for sustained and extended relief from cravings and withdrawal symptoms.

So while naltrexone does not work instantaneously, its effects are typically felt shortly after use, providing individuals with the support they need on their journey to recovery.
