Bonjesta (doxylamine / pyridoxine) treats morning sickness, or nausea and vomiting that happens during pregnancy. It's typically taken when changing your diet or staying away from nausea triggers isn't enough help. This medication contains an antihistamine called doxylamine and a dietary supplement called pyridoxine (also known as vitamin B6). The dosage is 1 tablet taken by mouth at bedtime, but it can be adjusted to 1 tablet in the morning and 1 tablet at bedtime if needed. This medication commonly causes sleepiness as a side effect.
Morning sickness (nausea and vomiting during pregnancy) when non-medication options haven't provided enough relief
Bonjesta (doxylamine / pyridoxine) is a combination medication containing two active ingredients that are thought to work together to relieve symptoms of morning sickness.
Doxylamine is an antihistamine. It blocks a natural chemical in the body called histamine from turning on the part of the brain that's responsible for nausea and vomiting.
Pyridoxine, another name for vitamin B6, is a dietary supplement. It's not clear how pyridoxine helps lessen nausea and vomiting during pregnancy.

Take Bonjesta (doxylamine / pyridoxine) on an empty stomach with a full glass of water. Food can make the medication take longer to work and also lessen how much of the medication gets absorbed into the body.
Swallow Bonjesta (doxylamine / pyridoxine) tablets whole. Don't crush, chew, or break the tablets before you swallow. Otherwise, the medication might not last as long in your system. Talk to your prescriber if you have trouble swallowing the tablets whole.
You can feel sleepy after you take Bonjesta (doxylamine / pyridoxine). Don't drive or do any activities that you need to concentrate for until you speak with your prescriber after you start taking this medication. It's dangerous to drive when you're sleepy, have trouble thinking clearly, or can't react quickly.
Avoid taking other antihistamines while you're taking Bonjesta (doxylamine / pyridoxine). It can put you at higher risk for serious side effects, like extreme sleepiness and confusion. Over-the-counter allergy, cough and cold medications, and sleep aids commonly have antihistamines in them. Ask your pharmacist if you're not sure whether any of your other medications contain an antihistamine.
Give your care team an up-to-date list of medications that you're taking. They can make sure your medications are safe to take together. It's not recommended to take Bonjesta (doxylamine / pyridoxine) if you're taking other medications that cause sleepiness, like muscle relaxers, sleep aids, and anxiety medications. It can cause severe sleepiness, which can lead to accidents and falls.
Other ways to help with morning sickness include eating dry crackers in bed in the morning so you're not moving around on an empty stomach. Then, make sure to drink enough water during the day. In addition, it can be easier on the stomach if you eat smaller portions of food (five or six smaller meals) instead of a few large meals throughout the day. You can also try ginger candies, ginger ale, and ginger tea.
Bonjesta (doxylamine / pyridoxine) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
