🩺 Clinical
The combination of doxylamine and pyridoxine is used to treat nausea and vomiting in pregnant women . Doxylamine is in a class of medications called antihistamines. It works by blocking the action of certain natural substances in the body that may contribute to nausea and vomiting. Pyridoxine (vitamin B6) is a vitamin. A lack of pyridoxine in the body may also be a factor in causing nausea and vomiting during pregnancy.

🔄 Drug Interactions ▾
7 DRUG INTERACTIONS Severe drowsiness can occur when used in combination with alcohol or other sedating medications. ( 7 )
7.1Drug Interactions Use of doxylamine succinate and pyridoxine hydrochloride delayed-release tablets is contraindicated in women who are taking monoamine oxidase inhibitors (MAOIs), which prolong and intensify the anticholinergic (drying) effects of antihistamines. Concurrent use of alcohol and other CNS depressants (such as hypnotic sedatives and tranquilizers) with doxylamine succinate and pyridoxine hydrochloride delayed-release tablets is not recommended.
7.2Drug-Food Interactions A food-effect study demonstrated that the delay in the onset of action of doxylamine succinate and pyridoxine hydrochloride delayed-release tablets may be further delayed, and a reduction in absorption may occur when tablets are taken with food [see Dosage and Administration (2) , Clinical Pharmacology (12.3) ] . Therefore, doxylamine succinate and pyridoxine hydrochloride delayed-release tablets should be taken on an empty stomach with a glass of water [see Dosage and Administration (2) ] .
7.3False Positive Urine Tests for Methadone, Opiates and PCP False positive drug screens for methadone, opiates, and PCP can occur with doxylamine succinate/pyridoxine hydrochloride use.

👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS Doxylamine succinate and pyridoxine hydrochloride delayed-release tablets are intended for use in pregnant women. ( 8.1 )
8.1Pregnancy Risk Summary Doxylamine succinate and pyridoxine hydrochloride delayed-release tablets are intended for the treatment of nausea and vomiting of pregnancy in women who do not respond to conservative management. Maternal risks are discussed throughout the labeling. No increased risk for congenital malformations has been reported in epidemiologic studies in pregnant women.
In the U.S. general population, the estimated background risks for major birth defects and miscarriage in clinically recognized pregnancies are 2% to 4% and 15% to 20%, respectively. Data Human Data The combination of doxylamine succinate and pyridoxine hydrochloride has been the subject of many epidemiological studies (cohort, case control and meta-analyses) designed to detect possible teratogenicity. A meta-analysis of 16 cohort and 11 case-control studies published between 1963 and 1991 reported no increased risk for malformations from first trimester exposures to doxylamine succinate and pyridoxine hydrochloride, with or without dicyclomine hydrochloride.
A second meta-analysis of 12 cohort and 5 case-control studies published between 1963 and 1985 reported no statistically significant relationships between fetal abnormalities and the first trimester use of the combination doxylamine succinate and pyridoxine hydrochloride with or without dicyclomine hydrochloride.
8.2Lactation Women should not breastfeed while using doxylamine succinate and pyridoxine hydrochloride delayed-release tablets. The molecular weight of doxylamine succinate is low enough that passage into breast milk can be expected. Excitement, irritability and sedation have been reported in nursing infants presumably exposed to doxylamine succinate through breast milk.
Infants with apnea or other respiratory syndromes may be particularly vulnerable to the sedative effects of doxylamine succinate and pyridoxine hydrochloride delayed-release tablets resulting in worsening of their apnea or respiratory conditions. Pyridoxine hydrochloride is excreted into breast milk. There have been no reports of adverse events in infants presumably exposed to pyridoxine hydrochloride through breast milk.
8.4Pediatric Use The safety and effectiveness of doxylamine succinate and pyridoxine hydrochloride delayed-release tablets in children under 18 years of age have not been established. Fatalities have been reported from doxylamine overdose in children. The overdose cases have been characterized by coma, grand mal seizures and cardiorespiratory arrest.
Children appear to be at a high risk for cardiorespiratory arrest. A toxic dose for children of more than 1.8 mg/kg has been reported. A 3 year old child died 18 hours after ingesting 1,000 mg doxylamine succinate.
However, there is no correlation between the amount of doxylamine ingested, the doxylamine plasma level and clinical symptomatology.

12.1Mechanism of Action The mechanism of action of doxylamine succinate and pyridoxine hydrochloride delayed-release tablets is unknown.
12.3Pharmacokinetics The pharmacokinetics of doxylamine succinate and pyridoxine hydrochloride delayed-release tablets has been characterized in healthy non-pregnant adult women. Pharmacokinetic results for doxylamine and pyridoxine, including its vitamin B6 metabolites, pyridoxal, pyridoxal 5’-phosphate, pyridoxamine and pyridoxamine 5’-phosphate, are summarized in Tables 2 to 5. Absorption A single-dose (two tablets) and multiple-dose (four tablets daily), open-label study was conducted to assess the safety and pharmacokinetic profile of doxylamine succinate and pyridoxine hydrochloride delayed-release tablets administered in healthy non-pregnant adult women.
Single-doses (two tablets at bedtime) were administered on Days 1 and 2. Multiple-doses (one tablet in the morning, one tablet in the afternoon and two tablets at bedtime) were administered on Days 3 to 18. Blood samples for pharmacokinetic analysis were collected pre-and post-dose on Days 2 and 18 as well as pre-dose prior to bedtime dose only (trough) on Days 9, 10, 11, 16, 17, and 18.
Doxylamine and pyridoxine are absorbed in the gastrointestinal tract, mainly in the jejunum. The C max of doxylamine and pyridoxine are achieved within 7.5 and 5.5 hours, respectively (see Table 2).
