Navalem (Doxylamine Hydrogen Succinate, Pyridoxine Hydrochloride)

Doxylamine hydrogen succinate blocks H1 histamine receptors in the brain, reducing vestibular stimulation that can trigger nausea. When paired with pyridoxine, which supports neurotransmitter synthesis, the combination enhances the anti‑emetic effect, helping to control vomiting episodes.

The specific dose of Navalem is determined by the prescribing clinician based on the patient’s condition, severity of symptoms, and individual response. Patients should follow the dosage instructions provided by their healthcare professional and not adjust the dose on their own.

Navalem is frequently used for nausea in pregnancy, but safety must be evaluated by a healthcare provider. While doxylamine has a long history of use in pregnancy, pyridoxine is a vitamin. Breastfeeding mothers should discuss potential risks and benefits with their clinician.

To place an order, submit an enquiry on the Navalem product page at gnhindia.com, specifying the required quantity.

Navalem’s combination of an antihistamine and vitamin B6 offers a dual mechanism that can be more effective for pregnancy‑related nausea than single‑agent antihistamines alone. Compared with metoclopramide or ondansetron, it generally has a milder side‑effect profile but may cause more sedation.

Navalem should be stored at ambient temperature, preferably below 25 °C. Keep the product in its original packaging, protect it from moisture and direct sunlight, and ensure the container is tightly closed to maintain stability.

Navalem is taken orally, usually with a glass of water. The tablet should be swallowed whole and not chewed or crushed unless directed otherwise by a healthcare professional.

Serious risks, though rare, include severe allergic reactions such as anaphylaxis, skin conditions like Stevens‑Johnson syndrome, cardiac arrhythmias, hepatic injury, and seizures. Patients should seek immediate medical attention if they experience symptoms such as rash, difficulty breathing, irregular heartbeat, jaundice, or convulsions.

Navalem is contraindicated in individuals with known hypersensitivity to doxylamine, pyridoxine, or any excipients in the formulation. It should also be avoided in patients with severe hepatic impairment, uncontrolled narrow‑angle glaucoma, or those taking medications that could cause dangerous additive sedation.
