What is the first-line treatment for nausea and vomiting in pregnancy?

Vitamin B6 supplements are considered the first-line treatment for nausea and vomiting in pregnancy, often referred to as morning sickness. This choice is supported by clinical guidelines due to Vitamin B6's safety profile and effective reduction of symptoms in pregnant individuals.

Vitamin B6, or pyridoxine, plays a crucial role in neurotransmitter synthesis, which can help alleviate nausea. Studies have shown that it is effective in treating mild to moderate nausea and vomiting during pregnancy without posing risks to the mother or developing fetus.

Other options, although they may provide relief in some cases, are typically used in different contexts or are not the primary recommendation for this specific condition. Ginger supplements can also be beneficial and considered a complementary treatment. Ondansetron is categorized as a prescription medication used for nausea but is generally reserved for more severe cases, and metoclopramide, while effective, carries a different risk profile and is not the first step recommended for uncomplicated cases of pregnancy-related nausea.
