Common use

Diclegis (doxylamine succinate 10 mg and pyridoxine hydrochloride 10 mg) is a delayed-release oral medication specifically prescribed for the treatment of nausea and vomiting of pregnancy (NVP), commonly known as morning sickness, in women who do not respond to conservative dietary and lifestyle measures alone. It is the only FDA-approved prescription medication for this indication. The dual-action formulation combines two well-established active ingredients: doxylamine succinate is an antihistamine (H1 receptor antagonist) that works by blocking histamine and acetylcholine receptors in the vomiting center of the brain, effectively suppressing the nausea signal. Pyridoxine hydrochloride (vitamin B6) supports normal amino acid metabolism and has been independently shown to reduce pregnancy-related nausea through mechanisms that are not fully understood but are believed to involve serotonin and other neurotransmitter modulation. Together, these ingredients provide safe and effective relief from moderate to severe morning sickness.

Dosage and direction

Diclegis delayed-release tablets are taken orally. The recommended starting dose is two tablets at bedtime on Day 1. If this adequately controls nausea and vomiting the next day, continue taking two tablets daily at bedtime. If symptoms persist into the next afternoon, the dose may be increased to three tablets: one in the morning and two at bedtime. If symptoms are still not adequately controlled, the maximum dose is four tablets daily: one in the morning, one in mid-afternoon, and two at bedtime. Swallow the tablets whole with water on an empty stomach; do not crush, chew, or split the delayed-release tablets, as this destroys the controlled-release mechanism. Follow your healthcare provider’s dosage instructions carefully and reassess the need for continued therapy periodically.

Precautions

Before taking Diclegis, inform your doctor if you have asthma, chronic obstructive pulmonary disease (COPD), narrow-angle glaucoma, stenosing peptic ulcer disease, pyloroduodenal or bladder neck obstruction, seizure disorders, or urinary retention. Because doxylamine has antihistaminic and anticholinergic properties, Diclegis may cause significant drowsiness and impaired cognitive function. Avoid driving, operating heavy machinery, or performing activities requiring alertness until you know how this medication affects you. Do not consume alcohol or take other CNS depressants (sedatives, tranquilizers, sleep aids) while taking Diclegis, as these can intensify drowsiness. Patients with hepatic impairment should use this medication with caution.

Contraindications

Do not use Diclegis if you are allergic to doxylamine succinate, pyridoxine hydrochloride (vitamin B6), or any other component of the tablet. Avoid concurrent use with monoamine oxidase inhibitors (MAOIs), as the combination can potentiate and prolong the anticholinergic effects of doxylamine. Do not use in combination with other sedating antihistamines without medical advice, as excessive sedation may occur.

Possible side effect

The most common side effect of Diclegis is drowsiness (somnolence), which is an expected pharmacologic effect of the doxylamine component. Other common side effects include dizziness, dry mouth, fatigue, headache, and mild gastrointestinal discomfort such as constipation or abdominal bloating. Less common effects may include blurred vision, urinary retention, or irritability. Serious side effects are rare but may include severe allergic reactions (rash, hives, angioedema, difficulty breathing), extreme sedation impacting consciousness, or paradoxical excitability. If you experience any severe, unusual, or persistent symptoms, discontinue use and seek medical attention promptly.

Drug interaction

Diclegis may interact with other sedative medications, including benzodiazepines, opioid analgesics, barbiturates, and sleep aids, causing additive CNS depression and excessive drowsiness. Alcohol significantly potentiates these effects and should be avoided. MAOIs are contraindicated, as they can prolong and intensify the anticholinergic effects of doxylamine. Other anticholinergic medications (certain antidepressants, antipsychotics, antiparkinson agents) may increase the risk of side effects such as dry mouth, urinary retention, and constipation when used concurrently. Inform your healthcare provider about all prescription drugs, over-the-counter products, and supplements you are taking.

Missed dose

If you miss a dose of Diclegis, take it as soon as you remember unless it is close to the time for your next scheduled dose. In that case, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to compensate. If morning sickness symptoms fluctuate, discuss dosage adjustments with your healthcare provider.

Overdose

An overdose of Diclegis may cause severe drowsiness, extreme sedation, confusion, respiratory depression, dry mouth, dilated pupils, flushing, tachycardia, or in severe cases, seizures, rhabdomyolysis, or coma. If you suspect an overdose, seek immediate emergency medical attention. Treatment is supportive and symptomatic, including airway management and monitoring of vital signs. Activated charcoal may be considered if the ingestion was recent.

Storage

Store Diclegis at room temperature between 20 and 25 degrees Celsius, away from heat, moisture, and direct light. Keep the tablets in the original container with the desiccant and out of the reach of children. Do not use after the expiration date printed on the packaging.
