Anxol Tablet (Doxylamine) Used to Treat Nausea, Vomiting, Insomnia, and Vertigo
Anxol Tablet (Doxylamine) is an antihistamine medication primarily used to treat insomnia (difficulty sleeping) and to relieve symptoms of nausea and vomiting, particularly morning sickness during pregnancy. It works by blocking histamine H1 receptors in the brain, producing a sedative effect that helps induce and maintain sleep.
Product Overview
Anxol Tablet is a highly effective, fast-acting medication containing Doxylamine, a potent first-generation histamine (H1) receptor antagonist belonging to the ethanolamine class. Characterized by its strong central nervous system penetrability, this medication delivers pronounced sedative and anti-allergic effects. Anxol Tablet is primarily utilized as a short-term clinical intervention for managing transient insomnia and sleep disturbances, while also serving as a valuable therapeutic option for relieving acute allergic reactions and upper respiratory symptoms.
Product Composition
- Active Ingredient: Doxylamine Succinate (Commonly available in 25 mg tablet strengths)
- Inactive Components: Typically includes lactose monohydrate, microcrystalline cellulose, dibasic calcium phosphate, sodium starch glycolate, and magnesium stearate.

Mechanism of Action
- The medication operates by reversibly binding to and blocking H1 receptors in both the peripheral tissues and the central nervous system.
- By crossing the blood-brain barrier and inhibiting central H1 receptors, it suppresses the stimulating action of histamine on the brain's arousal center, producing a profound sedative effect that facilitates sleep onset.
- Peripherally, it blocks the physiological actions of histamine, preventing the localized capillary dilation, swelling, and itching associated with allergic reactions.
- It also exhibits significant competitive antagonism at central and peripheral muscarinic acetylcholine receptors.
- This anticholinergic action dries up bodily secretions, reducing watery eyes and runny noses, while simultaneously contributing to its central sleep-inducing potency.
Key Benefits
- Rapid Sleep Induction: Significantly shortens sleep latency, helping individuals who suffer from acute restlessness fall asleep much faster.
- Improves Sleep Quality: Promotes a continuous, deeper sleep cycle, reducing frequent nighttime awakenings during periods of temporary stress.
- Effective Allergy Alleviation: Provides prompt relief from systemic allergic symptoms, such as sneezing, hives, and itchy skin.
- Dual-Action Cold Relief: Dries up excessive upper respiratory secretions, helping to clear congested airways associated with the common cold.
- Non-Habit Forming Alternative: Serves as an effective, short-term non-benzodiazepine alternative for sleep management when used as directed.
Usage
Dosage and administration for this medication must be carefully timed, particularly when it is being used to manage sleep difficulties. Because Anxol Tablet has strong sedative and anticholinergic properties, following proper guidelines ensures maximum efficacy while preventing daytime drowsiness.
Uses
Transient Insomnia: Used as a short-term therapeutic option to treat temporary sleep disturbances, restlessness, and difficulty falling asleep due to stress or jet lag.
Acute Allergic Reactions: Provides systemic relief from allergy symptoms, including hives (urticaria), skin rashes, and intense localized itching.
Allergic Rhinitis Symptoms: Alleviates upper respiratory distress by reducing sneezing, an itchy or runny nose, and watery eyes caused by seasonal allergies.
Common Cold Discomfort: Utilized in comprehensive multi-symptom cold treatments to dry up excessive nasal secretions and post-nasal drip.
Nausea Management: Occasionally used off-label or in specific combination formulations to help manage severe nausea and vomiting.
