How long do somas stay in your system?

Carisoprodol or Soma was developed in the latter half of the 50s and was initially used as an antiseptic. However, with time and multiple research, it was noted that Soma medication is a depressant of CNS that comes with minor properties for muscle relaxers high. Although the mechanism for its action hasn’t been completely elucidated, Soma and its prime metabolite named “Meprobamate” have been believed to modulate the GABA neurotransmitters indirectly via an indirect receptor agonism of GABAA. Further, this drug might yield an aspect of relaxation for the skeletal muscles by interrupting the neural communication occurring within the body’s reticular formation.

How long can Soma stay in the body’s system?

If you are a regular user of Soma, it is highly likely that you shall endure the potentially severe withdrawal symptoms from Soma, especially when it is discontinued no medical supervision.

Assuming that you have completely halted the consumption of Soma medicine, you might want to understand whether or not it stays in your system and for how long. In order to determine the duration of Soma present in your body post discontinuation, it might be important that you consider elimination of half-life for the medicine’s active ingredient known as “Carisoprodol”.

  • On average, Carisoprodol comes with elimination half-life that is of 2 hours approximately.
  • However, depending on the individual, the timing can vary from 1 hour to 3 hours.
  • Given this information, one can estimate the medication takes an average of 11 hours for the elimination of carisoprodol from the system.
  • Given the 1-3 hours range, Carisoprodol elimination can be as quick as 5.5 hours to as long as 16.5 hours.

With these numbers, one can estimate that after taking Soma, the Carisoprodol can empty out of the system within half of the day. However, it is very crucial for the patients to acknowledge that the carisoprodol is actually metabolized by the hepatic enzymes for the formation of a prominent metabolite named “meprobamate”. This metabolite comes with a half-life that ranges between 6 hours and 17 hours.

However, this number can be as high as 10 long hours. This ultimately states that even though carisoprodol is eliminated sooner, it takes meprobamate longer to be eliminated from the system. To sum it up, you can expect a time frame of less than 4 days for both carisoprodol and meprobamate to be eliminated from the body.

What are the Variables influencing the duration of Soma in the system?

Even though Soma flushes out of the system in less than 4 days, you can easily notice a difference in the elimination speed from one person to another. These differences for elimination speeds depend on series of variables like dosage ingested, administration term, co-administration drugs, and the person taking Soma.

1-Individual Taking Soma:

The time taken by the plasma in the body to eliminate Soma completely depends on various factors of the person taking it. This includes factors such as age, BMI, food intake, genetics, metabolic rate, hepatic function, renal function, sex, etc.


Dosage of carisoprodol or soma administered by you can also change the time duration of this drug being eliminated from the body. The higher the dosage, the longer is the elimination time period. Further, higher Carisoprodol dosage might lead to accumulation of meprobamate metabolite in the tissue of the body.

Now, one can also expect the drug and its metabolite to accumulate in the renal pathways just before elimination. This might lead to enhanced reabsorption, recirculation, and lastly prolonged excretion.

3-Administration Frequency:

Apart from the dosage of carisoprodol, it is important for one to consider frequency of this medication being used. Frequency means the total number of times you take this drug. Soma is rarely prescribed for long-term usage and this duration tends to play a major role when it comes to the duration for which Soma stays in the body.

4-Co-Administered Drugs:

While Soma doesn’t interact with many medications, it can definitely react with some drugs or supplements. When these drugs metabolize with Soma, it can lead to decreased elimination pace.

What are the Types of Drug Tests for Soma?

If you want to know if the drug carisoprodol has left your body or are still in place, you can do so by help from various tests which include:

Urine Tests: A fresh sample of urine can be analyzed with use of the LC-MS (Liquid-Chromatography/Mass Spectrometry). Soma can be detected several after ingestion in the urine.

Blood Tests: In order to determine the serum concentration of Soma or meprobamate in the blood, one can seek help from the lab technicians. Urine test is generally preferred over blood test as it is less invasive and less time-consuming. Additionally, blood test provides a shorter detection window.

Hair Tests: Another effective method to determine if an individual contains soma in the system, the lab technicians can collect some hair follicles from the scalp. Hair test provides a longer detection window which is more than 1 month.
