In the U.S., in accordance with the Controlled Substances Act, Soma is classified as a Schedule IV controlled substance. This classification means that this substance has a recognized potential for abuse and addiction.While it varies for each person, Soma usually stays in your system for an average of 11 hours. Soma metabolites remain in your system for up to four days after you stop taking it. Standard drug tests do not screen for Soma, so it is only be detectable if a person is specifically tested for it. Soma may be detectable on some tests for up to a month.

How Long Does It Take to Feel Effects?

Carisoprodol is broken down into meprobamate in the body, which is also active in its effects. Carisoprodol is absorbed and begins to have effects after 30 minutes. The pain-relief and muscle-relaxing effects last for 4 to 6 hours. Urine: Several days Hair: Up to a month While Soma may also reduce feelings of anxiety, it is not FDA-approved to help with anxiety.

How Long Does Soma Last?

The half-life of carisoprodol is about 1 to 3 hours, which varies depending on individual metabolism. The half-life of meprobamate is much longer, between 6 and 17 hours, which can lead to accumulation with multiple doses. Both carisoprodol and its metabolite meprobamate are excreted in the urine and can be detected for several days after the last dose. Your metabolism of Soma can be affected if you have ever had liver or kidney disease. A variety of factors can influence how long Soma stays in your system. These include:

Factors That Affect Detection

Carisoprodol and meprobamate can be detected on a screen for prescription or over-the-counter drugs in blood and urine, as may be done in the case of a suspected overdose. They typically aren’t included in a urine drug screen such as done for employment. Soma may be detectable in blood for up to 24 hours, but it may show up on urine tests for several days. This period may be longer for people who have been taking Soma for a long period of time. However, if you are taking a combination product that includes codeine, that will be detected. Be sure to disclose your medications to whoever is administering your test so they are able to better interpret the test results.
