Dexchlorpheniramine 2mg Tablets
SKU GME983Product Introduction
Dexchlorpheniramine 2mg is a first-generation antihistamine used to relieve allergic rhinitis, watery or itchy eyes and uncomplicated allergic skin symptoms such as hives. It can cause more sedation and anticholinergic effects than newer antihistamines. It does not replace emergency treatment for a severe allergic reaction.
How to use
Swallow the tablet with water, with or without food. Conventional tablets are usually taken at intervals through the day rather than treated as a once-daily extended-release product. Do not use the adult tablet schedule for a child or add another sedating cold-and-allergy medicine.
How it works
Dexchlorpheniramine competes with histamine at H1 receptors, reducing histamine-mediated itching, sneezing and watering. It also enters the brain and has anticholinergic activity, contributing to sedation and dryness.
Side effects
Drowsiness, dizziness, dry mouth, blurred vision, constipation and difficulty passing urine may occur. Children and older adults can occasionally develop excitation or confusion instead of sedation. Severe allergy or marked breathing difficulty requires urgent help.
Important information
Avoid alcohol and driving if alertness is impaired; next-day drowsiness is possible. Tell your doctor about narrow-angle glaucoma, prostate enlargement, urinary retention, bowel obstruction, seizures, pregnancy and breastfeeding. MAO inhibitors and other sedatives can interact. Older adults are more vulnerable to falls and anticholinergic effects.
Uses
- Allergic rhinitis or rhinoconjunctivitis
- urticaria and other uncomplicated histamine-mediated allergic skin symptoms.
Benefits
Blocking histamine can reduce itch, repeated sneezing and eye or nasal watering during an allergy episode. The useful symptom relief must be balanced against reduced daytime alertness.
Is dexchlorpheniramine the same as chlorpheniramine?
They are related, but dexchlorpheniramine is the active dextrorotatory isomer. Their milligram doses are not interchangeable without adjustment.
Can Dexchlorpheniramine 2mg be used as a sleeping tablet?
Sleepiness is an adverse effect, not a reason to use it as a long-term insomnia treatment. Repeated sedating-antihistamine use can cause tolerance and troublesome anticholinergic effects.
Why can an antihistamine make a child restless?
First-generation antihistamines can occasionally produce paradoxical excitation rather than sleepiness. An adult dose should never be used to try to settle a child.
Will it help during anaphylaxis?
It cannot reliably reverse airway swelling or shock. Adrenaline and emergency care are the key treatment; an oral antihistamine must not delay them.
