Soma (carisoprodol) has a half-life elimination of 2.4 hours. The active metabolite meprobamate has a half-life elimination of 10 hours -- in healthy individuals. Generally, compounds and their metabolites are detectable in urine for 5 (five) half-lives. So, carisoprodol is detectable in urine for 50 hours after ingestion.
