Product Overview

Introduction of Duopharma Chloramine 4mg Tablet 10s (strip)

Duopharma Chloramine 4mg Tablet is a locally manufactured antihistamine medication produced by Duopharma Biotech, one of Malaysia's most trusted pharmaceutical companies, with chlorpheniramine maleate as its active ingredient. If you've been dealing with sneezing, itchy eyes, or runny nose and looking for a reliable, affordable option, this is one of those medicines that has been around for a long time and is well-recognised in Malaysian households and clinics alike. Like most antihistamines, it may cause some side effects such as drowsiness, dry mouth, dizziness, and blurred vision — so it's good to be aware of these before you start taking it. It's important that you follow your doctor's or pharmacist's advice on how and when to take this tablet, especially if you have other health conditions or are currently on other medications.

How to Take Duopharma Chloramine 4mg Tablet

Duopharma Chloramine 4mg Tablet should be taken orally with a full glass of water, and it can be taken with or without food — though taking it with food may help if you experience any stomach discomfort. It is generally advisable to take it at the same time each day as directed by your doctor or pharmacist, and you should swallow the tablet whole without crushing or chewing it. Since this medication may cause drowsiness, many people prefer to take it in the evening or before bedtime unless otherwise instructed by a healthcare professional.

Dosage of Duopharma Chloramine 4mg Tablet

The typical recommended dose for adults and children above 12 years is one tablet (4mg) taken every 4 to 6 hours, with a maximum of 6 tablets (24mg) in a 24-hour period, unless your doctor advises differently. For children aged 6 to 12 years, a lower dose is usually recommended, so always consult your pharmacist or doctor before giving this medication to a child.

Shelf Life of Duopharma Chloramine 4mg Tablet

Duopharma Chloramine 4mg Tablet generally has a shelf life of 2 to 3 years from the date of manufacture, as indicated on the product packaging. Always check the expiry date printed on the box or blister pack before use, and do not consume the tablet if the expiry date has passed. If you are purchasing this product online, rest assured that our pharmacy only stocks products with valid, verified expiry dates to ensure your safety.

How to Store Duopharma Chloramine 4mg Tablet

  • Store Duopharma Chloramine 4mg Tablet in a cool, dry place below 30°C, away from direct sunlight, heat, and moisture.
  • Keep the tablets in their original packaging to protect them from environmental exposure.
  • As with all medications, store this product out of reach of children and pets at all times.
  • Avoid storing it in the bathroom or kitchen where humidity levels tend to be higher, as moisture can affect the quality and integrity of the tablet.

Active Ingredient of Duopharma Chloramine 4mg Tablet

The active ingredient in Duopharma Chloramine 4mg Tablet is:

  • Chlorpheniramine Maleate 4mg

Chlorpheniramine maleate is a first-generation antihistamine that belongs to the alkylamine class of antihistamines. It works by blocking histamine H1 receptors in the body. Each tablet contains 4mg of this active ingredient, along with approved pharmaceutical excipients that support tablet formulation and stability.

Note: This is not a complete list of all possible side effects. If you notice any unusual symptoms after taking this medication, stop use and consult your doctor or pharmacist promptly.

Contraindications of Duopharma Chloramine 4mg Tablet

  • Hypersensitivity: Individuals who are known to be allergic to chlorpheniramine maleate or any other component of the tablet
  • Neonates and premature infants: This medication is contraindicated in very young infants
  • Patients taking Monoamine Oxidase Inhibitors (MAOIs): Concurrent use or use within 14 days of stopping MAOI therapy is contraindicated due to risk of serious drug interactions
  • Narrow-angle glaucoma: Chlorpheniramine can increase intraocular pressure, making it unsafe for patients with this eye condition
  • Urinary retention or bladder neck obstruction: The anticholinergic properties of this medication may worsen urinary difficulties
  • Severe hepatic impairment: Patients with significant liver disease should avoid this medication unless specifically advised by a physician
  • Prostatic hypertrophy: Men with an enlarged prostate may experience worsening of urinary symptoms
  • Stenosing peptic ulcer or pyloroduodenal obstruction: The anticholinergic effects may aggravate these gastrointestinal conditions

Always inform your doctor or pharmacist about your full medical history and current health conditions before starting this medication.

Drug & Food Interaction of Duopharma Chloramine 4mg Tablet

It is important to be aware of potential interactions between Duopharma Chloramine 4mg Tablet and other substances. Always inform your healthcare provider about all medications, supplements, and dietary habits before use.

Drug Interactions:

  • Central Nervous System (CNS) Depressants — Including sedatives, sleeping pills, tranquillisers, and opioid pain relievers; combining these with chlorpheniramine may intensify drowsiness and sedation
  • Monoamine Oxidase Inhibitors (MAOIs) — Serious and potentially life-threatening interactions can occur; concurrent use is strictly contraindicated
  • Alcohol — Significantly increases sedative effects; avoid alcohol consumption while taking this medication
  • Anticholinergic Drugs — Medications such as certain antidepressants, bladder medications, or antispasmodics may compound anticholinergic side effects such as dry mouth, constipation, and urinary retention
  • Tricyclic Antidepressants (TCAs) — May enhance the sedative and anticholinergic effects of chlorpheniramine
  • Beta-blockers — Some interactions have been noted; consult your doctor if you are on beta-blocker therapy
  • Phenytoin — Chlorpheniramine may inhibit the metabolism of phenytoin, potentially increasing its plasma levels

Food Interactions:

  • Alcohol (including alcoholic beverages) — Must be avoided as it significantly amplifies drowsiness and impairs coordination and judgment
  • Grapefruit juice — While not a major established interaction for chlorpheniramine specifically, it is generally advisable to take medications with plain water unless otherwise directed
  • Caffeinated beverages — May partially counteract drowsiness but do not eliminate the sedative effect or impairment caused by the medication; do not rely on caffeine to offset sedation

Reminder: This list may not cover all possible interactions. Always disclose your full medication list — including over-the-counter medicines, herbal supplements, and vitamins — to your doctor or pharmacist before starting Duopharma Chloramine 4mg Tablet.

Quick Tips for Duopharma Chloramine 4mg Tablet

  • Do not drive or operate heavy machinery after taking this tablet, as it may cause drowsiness and slow your reaction time
  • Take the tablet with food or milk if you experience any stomach discomfort after consumption
  • Avoid alcohol completely while on this medication — the sedative effects can be dangerously amplified
  • Do not exceed the recommended dose — taking more than prescribed will not improve your condition faster and may increase your risk of side effects
  • Store in a cool, dry place away from sunlight and humidity; avoid storing in bathrooms or near kitchen sinks
  • Check the expiry date before taking any tablet — never use medicine that has expired
  • Keep out of reach of children — store in a secure location, preferably in a locked medicine cabinet
  • Inform your pharmacist or doctor if you are pregnant, breastfeeding, elderly, or have any chronic health conditions before taking this medication
  • Do not share your medication with others, even if they appear to have the same symptoms
  • Dispose of unused or expired tablets responsibly — return them to a pharmacy for proper pharmaceutical waste disposal rather than throwing them in household rubbish
  • If you miss a dose, take it as soon as you remember — but if it's almost time for your next dose, skip the missed one and continue as normal; never double up on doses
