What Is This Medicine Exactly?
This medicine is a helpful combination of two active ingredients working together. The first ingredient is doxylamine, which belongs to a group of medicines known as antihistamines. The second ingredient is vitamin B6, also known as pyridoxine, which your body naturally needs. When combined, these two ingredients block specific chemical signals in your body that trigger nausea and vomiting.
Medical experts and major health organizations around the world recognize this combination as safe for pregnant women. Clinical studies show it helps reduce pregnancy sickness when lifestyle changes and diet adjustments are not enough. Even though it is generally safe, you must only use it under the direct guidance of your doctor or midwife.

To get the best results and keep yourself safe, you must take your medicine exactly as directed. Follow these simple steps for proper use during your pregnancy:
- Swallow tablets whole with water: Never crush, chew, or break the tablets. They use a delayed-release or extended-release design that needs to dissolve slowly in your body.
- Take on an empty stomach: Taking your dose on an empty stomach often helps your body absorb the medicine more effectively.
- Stick to a regular schedule: Try to take your medicine at the same time every day as advised by your doctor.
- Never stop suddenly on your own: Continue taking your medicine until your doctor tells you it is safe to stop.
- What to do for a missed dose: Take your missed dose as soon as you remember. If it is almost time for your next scheduled dose, skip the missed one and stay on your normal schedule. Never take a double dose to make up for a missed one.
