Carisoprodol is a muscle relaxant primarily prescribed to help reduce pain in those who have suffered a strain, sprain, or other musculoskeletal injury or condition. Although the usual dosage of 350 mg is unlikely to cause any severe reactions other than extreme drowsiness, some may still experience some uncomfortable side effects. Carisoprodol side effects may affect the central nervous system, the gastrointestinal (GI) tract, or cardiovascular system. This drug is also considered habit forming, and abuse of this substance has been known to occur.
Some of the most common carisoprodol side effects are related to the central nervous system. Extreme drowsiness and deep sleep are some of the most frequently experienced reactions at the normal dosage of 350 mg. Dizziness and headache, agitation, fainting, and uncoordinated muscle movements are also possible reactions. Though rare, central respiratory depression may result from higher doses.
In some cases, carisoprodol side effects may involve the GI tract and cardiovascular system. GI side effects can include nausea and vomiting, hiccups, or abdominal pain. Some cardiovascular symptoms are uncomfortable but mild, such as facial flushing, while others may require a visit to the doctor. These reactions can include a rapid heart rate or abnormally low blood pressure.
Hypersensitivity symptoms are also possible carisoprodol side effects. These symptoms often include skin reactions such as rashes or itchiness. In addition, asthma and a high fever may be triggered by this drug. Severe allergic reactions are uncommon, but may occur in some people and can include a marked shortness of breath, dizziness, or swelling of the tongue, throat, or face.
Idiosyncratic, or rare but severe, side effects have occasionally occurred while taking this medication, and usually develop shortly after the first dose is taken. These symptoms may include extreme weakness, mood or vision changes, joint pains, or the inability to move the extremities. Should these side effects occur, patients are advised to seek medical attention immediately.
Carisoprodol is thought to be a habit-forming drug and, if taken improperly, may result in addiction. Additionally, this medication may cause a number of withdrawal side effects if suddenly discontinued. Some of the most common symptoms include sleep disturbances, headache, stomach pain, and seizures. Patients are often advised to consult a doctor prior to quitting this drug, as he may prescribe smaller doses to help gradually wean the patient off it.
