Understanding the Generic Name for Cariban
Cariban is a brand name for a prescription medication used to treat nausea and vomiting in pregnant women (NVP), commonly known as morning sickness. The generic name for Cariban is doxylamine succinate and pyridoxine hydrochloride. This combination is a well-established and extensively used treatment, with decades of clinical experience in Europe and beyond. Doxylamine is an antihistamine, while pyridoxine is a form of vitamin B6. Together, they provide symptomatic relief for those who do not respond to more conservative management, such as dietary or lifestyle changes.
The Role of Doxylamine and Pyridoxine
Each component of the Cariban combination plays a distinct role in alleviating NVP symptoms:
- Doxylamine: As an antihistamine, doxylamine works by blocking the action of histamine at the H1-receptors in the body. By doing so, it helps to block signals in the brain that trigger nausea and vomiting. Doxylamine is also known for its sedative properties, which can help with restlessness or difficulty sleeping associated with NVP.
- Pyridoxine: Also known as vitamin B6, pyridoxine has an antiemetic effect that has been documented since the 1940s, though its exact mechanism of action is not completely understood. It is believed that a lack of pyridoxine may be a factor in causing nausea and vomiting during pregnancy, and its supplementation helps to lessen these symptoms.
How Cariban Compares to Other Formulations
Cariban is a modified-release hard capsule containing pellets of doxylamine and pyridoxine. The modified or prolonged-release formulation is designed to provide a gradual and sustained release of the active ingredients over time. This differs from immediate or delayed-release tablets by avoiding a large dose being dumped into the system at once. The prolonged release profile is beneficial for maintaining a more continuous level of medication in the bloodstream, helping to control symptoms throughout the day and night.

Dosage and Side Effects

Less common side effects can include dizziness, headache, or restlessness. It is crucial to avoid alcohol and other central nervous system depressants while taking Cariban, as this can increase drowsiness.

However, as with any medication during pregnancy, it is essential to discuss its use with a healthcare professional to ensure it is appropriate for your specific condition.
