The 111 White Pill: Exploring its Connection to Soma

The 111 White Pill: Exploring its Connection to Soma


The round white 111 pill is a Soma 350 mg tablet that is imprinted with “111” on one side and “O” on the other. It is a white round pill and is prescribed for managing short-term acute pain within 30 minutes of intake. 



Soma 350mg pill, also known as 111 pills, the brand name of Carisoprodol, is a muscle relaxant prescribed for short-term acute pain. Brand drugs are manufactured and marketed by different pharmaceutical companies. This is why they may have different appearances and markings (imprints), even though they contain the same active ingredient.


What Is 111 Round White Pill? 

The Soma 350 mg, which is specifically manufactured by Oxford Pharmaceuticals, is also known as the round white pill 111. It is called so because it has “O” imprinted on one side of the tablet and “111” on the other. 




The carisoprodol pill is also available in other imprints, such as Dan 5513, which is manufactured by Watson Pharmaceuticals (now Allergan Pharmaceutical Company).

Medical Use Of The 111 Round White Pill

Soma 350 mg is indicated to relieve pain associated with acute musculoskeletal conditions. It is preferable for beginners or for people with mild to moderate body pain. 

Soma pills can be taken for pain associated with the following conditions- 

  • For back pain.

  • Muscle cramps.

  • Headaches and migraines.

  • For menstrual cramps. 

The use of Soma for anxiety is an off-label benefit of the muscle relaxer and should only be taken under medical supervision. 

The beneficial use of carisoprodol in treating fibromyalgia comes to light in a comparative study of Soma vs Baclofen. Fibromyalgia is long-lasting chronic pain that results in fatigue, insomnia, and tenderness throughout the body. The Soma pill is seen to show more effective results than Baclofen. 


Working Mechanism 

Following oral administration, carisoprodol is metabolized in the liver and eliminated through the kidney. It is metabolized to form meprobamate, which contributes to the muscle relaxer's effectiveness and abuse potential. 

The Soma pill's analgesic effect blocks the pain's sensation from reaching the person's brain. The action of the muscle relaxer begins within 30 minutes and lasts for 4 to 5 hours. 


Dosage And Administration 




The white 111 pill is available as Soma 350mg and does not retail in higher strengths such as 500mg. The dose can be taken 3 to 4 times daily for 3 weeks. Long-term use of the muscle relaxer can result in dependency. 

The administration of the Soma 111 pill should be done by following the below-mentioned routine. 

  • It is an oral pill and thus should be swallowed by mouth.
