Product Overview

Introduction of Dextrophan 15mg Syrup 90ml

Dextrophan 15mg Syrup is an antitussive (cough suppressant) medication that contains Dextromethorphan Hydrobromide as its active ingredient, belonging to the morphinan class of cough suppressants that works centrally on the brain's cough centre. This syrup is a commonly recognised over-the-counter formulation that many families in Malaysia keep within reach. Like any medication, it's good to know that some people may experience dizziness, drowsiness, nausea, or mild stomach upset while taking it — so it's always wise to be informed before you start. Whether you're a first-time buyer or someone who's used it before, you'll want to know things like the right dose, how to store it safely, and whether it suits your current health condition — and we've got all of that covered for you right here.

How to Take Dextrophan 15mg Syrup

Dextrophan 15mg Syrup should be taken orally, measured carefully using the dosing cup or measuring spoon provided — never estimate with a regular household spoon, as this can lead to incorrect dosing. It can be taken with or without food, though taking it with a small amount of water or after a light meal may help reduce any mild stomach discomfort. Always follow the dosage instructions on the label or as directed by your doctor or pharmacist, and do not exceed the recommended dose.

Dosage of Dextrophan 15mg Syrup

For adults and children aged 12 years and above, the generally recommended dose is 15mg (one standard dose) taken every 6 to 8 hours, not exceeding 4 doses in a 24-hour period. For children below 12 years, dosage should always be determined by a healthcare professional based on the child's age and body weight — please consult your pharmacist or doctor before administering to younger children.

Shelf Life of Dextrophan 15mg Syrup

Dextrophan 15mg Syrup typically has a shelf life of 2 to 3 years from the date of manufacture when stored under the recommended conditions and remains unopened. Once the bottle has been opened, it is generally advisable to use the syrup within 3 to 6 months and to check the expiry date printed on the packaging before each use. Never use the product beyond its stated expiry date, even if it appears unchanged in colour or consistency.

How to Store Dextrophan 15mg Syrup

  • Store at room temperature between 15°C to 30°C, away from direct sunlight and heat sources.
  • Keep the bottle tightly closed after each use to prevent contamination and evaporation.
  • Do not refrigerate or freeze the syrup unless specifically instructed on the packaging.
  • Store in a dry place, away from humid environments such as bathrooms or kitchen sinks.
  • Keep out of reach of children at all times.
  • Do not transfer the syrup into another container — always keep it in its original packaging.

  • Check the expiry date before every use, especially if the bottle has been sitting in your medicine cabinet for a while.

  • Consult a pharmacist or doctor if your cough persists beyond 7 days, worsens, or is accompanied by fever, rash, or persistent headache.
  • Keep out of children's reach — store in a secure, locked medicine cabinet if possible.
  • Dispose of unused or expired syrup responsibly — return it to a pharmacy for proper disposal rather than pouring it down the drain.
