Doxibion: Uses, Benefits, Dosage, Side Effects, Interactions

Doxibion is a combination medicine containing Doxylamine Succinate, Pyridoxine Hydrochloride, and  Folic Acid. Doxibion is used for the treatment of vomiting and nausea associated with pregnancy in women who do not respond to conservative management.

Doxibion is also used to relieve symptoms of allergy, hay fever, and the common cold. This medication works by blocking certain natural substances (histamine, acetylcholine) that your body makes. This effect helps to relieve allergy, and cold symptoms such as watery eyes, runny nose, and sneezing.

 It also helps to treat or prevent vitamin B6 deficiency. It is also used to treat a certain type of anemia (lack of red blood cells).

Each tablet of Doxibion contains the following active ingredients: Doxylamine Succinate 20 mg, Pyridoxine Hydrochloride 20 mg & Folic Acid 5 mg.

How it works

The Doxylamine Succinate in Doxibion reduces nausea and vomiting by inhibiting histaminergic signaling to the vomiting center in the medulla.

Pyridoxine (vitamin B6) is a vitamin. It is given because a lack of pyridoxine in the body may also be a factor in causing nausea and vomiting during pregnancy.

The folic acid in Doxibion works by restoring the levels of vitamin B6 in the body and treats nausea and vomiting during pregnancy. Folic acid is also a form of vitamin B which can provide essential nutrients during pregnancy. You should take this medicine exactly as prescribed by the doctor.

In synergy, these three active ingredients work to prevent nausea and vomiting in pregnancy. In a clinical study, morning sickness symptoms improved after 2 weeks of taking this combination. These symptoms included how many times the participants vomited and how long they felt nauseous.


Do not use Doxibion if you have used an MAO inhibitor in the past 14 days, such as isocarboxazid, linezolid, methylene blue injection, phenelzine, rasagiline, selegiline, or tranylcypromine.

If your symptoms of nausea and vomiting are not better, then your doctor may tell you to take the Doxibion tablet two or three times a day, or the extended-release tablet two times a day.

Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take Doxibion exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
