Pyridoxine 10mg | Doxylamine 10mg | Ginger 10mg

Route: Oral capsule.

• Take as directed by the prescriber, typically 1–2 capsules at bedtime with or without food, with the option to add a morning dose if symptoms persist through the day.
• Swallow whole with water. Do not crush or chew.
• Doxylamine's sedative properties make bedtime dosing advantageous; morning drowsiness is common with doxylamine—patients should not drive or operate heavy machinery until they know how the medication affects them.

Prescriber-determined and patient-specific. ACOG stepwise approach for pharmacologic NVP treatment recommends pyridoxine (10–25 mg every 8 hours) with doxylamine (12.5 mg every 8 hours) as first-line; the Diclegis-equivalent dose is 10 mg of each at bedtime, with dose escalation to morning and afternoon doses as needed. Ginger 10 mg is supplemental to this backbone. General reference:

• Starting: 1 capsule at bedtime.
• If symptoms persist: may add 1 capsule in the morning (per prescriber direction).
• Maximum recommended duration of doxylamine-containing therapy: reassess at 6 weeks per prescriber.

• Pyridoxine: The exact mechanism by which B6 reduces NVP is unknown. It may modulate serotonin synthesis and metabolism (serotonin plays a role in the chemoreceptor trigger zone), or correct a relative deficiency in the context of pregnancy-related metabolic demands.
• Doxylamine: Blocks H1 histamine receptors centrally (vestibular nucleus, chemoreceptor trigger zone) and peripherally; its anticholinergic properties reduce smooth muscle tone in the GI tract. The combination with pyridoxine has synergistic antiemetic activity exceeding either agent alone.
• Ginger: Gingerols and shogaols (bioactive phenolic compounds) act as 5-HT3 serotonin receptor antagonists and substance P (NK1 receptor) antagonists at the chemoreceptor trigger zone and GI tract, mechanisms shared with ondansetron and aprepitant. Ginger also inhibits gastric lipase and promotes gastric motility, reducing gastric stasis that contributes to nausea.

Indication context: Nausea and vomiting of pregnancy affects 50–80% of pregnant women; it typically begins by week 4–6, peaks around week 8–10, and resolves by week 12–16 in most cases, though approximately 10% experience persistent symptoms into the second or third trimester. ACOG recommends pyridoxine ± doxylamine as first-line pharmacologic therapy after dietary and lifestyle modifications fail. Ginger has Level I evidence (randomized trials) supporting its use as a complementary antiemetic in NVP.

Monitoring considerations:

• Assess severity using the PUQE (Pregnancy-Unique Quantification of Emesis) score at each visit.
• Monitor hydration status, electrolytes, and weight; escalate treatment or consider IV hydration if weight loss exceeds 5% of pre-pregnancy weight or ketonuria is present.
• Alert for hyperemesis gravidarum (HG)—this medication is not studied for HG management.
• Monitor for excessive sedation; advise against driving until daytime response to doxylamine is established.

Contraindications:

• Hypersensitivity to pyridoxine, doxylamine, ginger, or any formulation excipient.
• Concurrent use of MAOIs (doxylamine's anticholinergic/antihistaminic effects may be intensified; serotonin syndrome risk with MAOIs and B6).

Warnings & Precautions:

• Somnolence and impaired alertness: doxylamine's sedative properties require patients to avoid driving or operating heavy machinery until individual daytime response is known.
• False-positive urine drug screens for methadone, opiates, and PCP have been reported with doxylamine-containing products.
• Anticholinergic effects: urinary retention, constipation, dry mouth, blurred vision—use with caution in patients with glaucoma or prostatic hypertrophy.
• Do not breastfeed while using doxylamine; it may cause sedation and irritability in nursing infants, and may impair lactation.
• Ginger at doses above 250 mg three times daily has theoretical antiplatelet effects; use caution in patients with bleeding disorders or on anticoagulants.

Drug Interactions:

• CNS depressants (alcohol, benzodiazepines, opioids): enhanced sedation with doxylamine.
• MAOIs: avoid concurrent use.
• Anticoagulants (warfarin, heparin): ginger may potentiate antiplatelet/anticoagulant effects; monitor if applicable.

Common Side Effects: Somnolence (most common), dry mouth, constipation, dizziness, headache; nausea paradoxically may worsen briefly at initiation.

Store at room temperature (15–30°C / 59–86°F) in a cool, dry location. Protect from moisture and direct light. Keep tightly capped. Keep out of reach of children (and pets). Use within the beyond-use date assigned by Genesis Compounding per USP <795> standards.

Why is ginger added to the pyridoxine and doxylamine?

Ginger has independently demonstrated antiemetic activity in randomized trials for NVP through complementary mechanisms—blocking serotonin (5-HT3) and substance P pathways at the chemoreceptor trigger zone. Adding ginger to the pyridoxine-doxylamine backbone may provide additional nausea relief through these distinct pathways without significant additional risk.

When should I take this capsule?

Your prescriber will direct the timing. A common starting regimen is one capsule at bedtime. If nausea persists through the morning or during the day, your prescriber may recommend additional daytime doses. Bedtime dosing allows doxylamine's sedative effects to aid sleep without daytime impairment.

Is it safe for my baby?

Pyridoxine is FDA Pregnancy Category A (well-established safety in pregnancy). Doxylamine-pyridoxine (Diclegis/Bonjesta) is the only FDA-approved prescription product for NVP and has an extensive safety record from decades of use and large meta-analyses showing no increased risk of birth defects. Ginger at recommended doses has not been associated with teratogenicity in clinical studies. Always discuss any medication use during pregnancy with your prescriber.

Can I drive after taking this medication?

Doxylamine causes sedation in many patients. Do not drive, operate heavy machinery, or engage in activities requiring full alertness until you know how this medication affects you. Bedtime dosing minimizes daytime sedation for most patients.

Is this combination FDA-approved?

Pyridoxine 10 mg + doxylamine 10 mg is available as FDA-approved Diclegis. Ginger is not included in the FDA-approved product. This three-ingredient compounded capsule is a patient-specific 503A preparation from Genesis Compounding that is not FDA-approved as a compounded product.
