Why is there no information here about what Pharmaniaga Dextromethorphan Syrup is for?

This page is limited to product, safety and handling information in line with Malaysian rules on medicine information. If you want advice on whether this product suits you, book an online consultation with a doctor or pharmacist on DoctorOnCall.

How should I use Pharmaniaga Dextromethorphan Syrup?

Use it exactly as stated on the pack label, without changing the amount or how often you use it. If anything on the label is unclear, check with a pharmacist before the first use, and read the Directions for Use section on this page.

Can I speak to a doctor or pharmacist about Pharmaniaga Dextromethorphan Syrup before I buy it?

Yes. DoctorOnCall offers online consultations with licensed doctors and registered pharmacists, so you can ask about this product, your existing medicines, or anything on the label before you place an order.

What should I do if I notice side effects after using Pharmaniaga Dextromethorphan Syrup?

Stop using the product and speak to a doctor or pharmacist about any reaction that concerns you. Seek medical care immediately for signs of a severe reaction such as difficulty breathing, swelling of the face, lips or throat, or a widespread rash. Reported reactions are listed in the Side Effects section on this page.

How long will delivery take?

Within Malaysia, standard delivery takes 3 to 5 working days. Same-day delivery is available in the Klang Valley for orders placed before 12pm; orders placed after 12pm arrive by the end of the next day. Orders to Singapore are sent as international deliveries and take 5 to 9 working days. A lump-sum shipping and handling fee applies to every overseas delivery and is shown at checkout.

What payment methods can I use?

Customers in Malaysia can pay by FPX online banking, credit or debit card (Visa and Mastercard), and supported e-wallets including Touch ‘n Go eWallet, GrabPay and ShopeePay. FPX and local e-wallets are tied to Malaysian bank and wallet accounts, so if your delivery address is in Singapore, use the payment options displayed at checkout for that address rather than assuming the same list applies.

Can Pharmaniaga Dextromethorphan Syrup be delivered to Singapore?

Yes. DoctorOnCall ships to Singapore as an international order dispatched from Malaysia, arriving in 5 to 9 working days with a lump-sum shipping and handling fee. Singapore’s Health Sciences Authority (HSA) allows personal imports of up to three months’ supply of a medicine for your own use or an immediate family member’s, as long as it contains no controlled drugs, psychotropic substances or prohibited items. Keep the product in its original labelled packaging and keep a copy of your prescription or doctor’s letter with it. Quantities above three months’ supply, and medicines containing controlled substances, require prior HSA approval.

Is Pharmaniaga Dextromethorphan Syrup registered with the authorities?

Products listed on DoctorOnCall are registered with Malaysia’s Ministry of Health for supply in Malaysia, and each pack carries its MAL registration number. An order delivered to Singapore arrives as a personal import of a Malaysia-registered product; HSA product registration is not required for personal-use quantities, but it is also not the same as a product registered for sale in Singapore. If you need a locally registered Singapore product, buy it from a pharmacy in Singapore.

Who do I contact if there is a problem with my order?

DoctorOnCall’s customer care team handles order, delivery and product queries through the contact channels on the site, including WhatsApp and the online help centre. For deliveries to Singapore, allow more time before chasing an order than you would for a local Malaysian delivery, as the parcel passes through customs clearance and tracking updates can appear later in the journey.

Overview

Pharmaniaga Dextromethorphan Syrup is supplied as a syrup, with Dextromethorphan hydrobromide, at the strength stated on the product label. It is supplied in a pack size of 120ml.

No prescription is required for this product, as it is a non-prescription medicine. This page is limited to product, safety and handling information.

If you would like guidance before buying, you can speak to a doctor or pharmacist through an online consultation on DoctorOnCall. Orders are dispensed by a registered pharmacist and delivered to your address.

Directions for Use

Shake the bottle well before use and measure each dose using the measuring cup or spoon provided rather than a regular household spoon, to ensure accuracy. Take the syrup by mouth at the intervals stated on the product label, and do not exceed the maximum recommended daily dose or duration of use. Do not take this product together with other cough, cold, or flu medicines that also contain dextromethorphan, as this can lead to accidental overdose.

Dosage

Adults and children should follow the age-based dosing instructions printed on the product label or as advised by a doctor or pharmacist, taken at the stated interval and not exceeding the maximum daily amount specified. This syrup is intended only for short-term use, generally no more than about 7 days; if the cough persists beyond this, worsens, or is accompanied by fever, chest pain, or difficulty breathing, stop self-treatment and see a doctor. If a dose is missed, take it when remembered, but do not double up to make up for a missed dose.

Storage Instructions

Store Pharmaniaga Dextromethorphan Syrup below 30°C in a dry place, away from direct sunlight, and keep the bottle tightly closed when not in use. Keep out of the reach and sight of children.

Side Effects

Drowsiness or dizziness
Nausea or vomiting
Stomach discomfort
Mild confusion (especially at high doses)
Dry mouth

Contraindications

Known hypersensitivity to dextromethorphan or any ingredient in the syrup.
Current use of, or use within the past 14 days of, a monoamine oxidase inhibitor (MAOI).
Chronic or productive cough associated with excessive phlegm, such as in chronic bronchitis, emphysema, or smoking-related cough, unless advised by a doctor.
Children under the age stated on the product label.

Drug / Food Interactions

Should not be combined with MAOIs due to the risk of a serious reaction involving high body temperature, agitation, and rapidly changing blood pressure.
May increase drowsiness when taken with alcohol, sedatives, or other medicines that cause sleepiness.
Certain antidepressants (SSRIs) may increase the risk of serotonin-related side effects when combined with dextromethorphan.
Do not combine with other cough, cold, or flu products containing dextromethorphan to avoid duplicate dosing.

Quick Tips

Use only for dry, non-productive cough — not for a wet or phlegm-producing cough.
Always measure doses with the provided cup or spoon, not a kitchen spoon.
Avoid driving or operating machinery until you know how this syrup affects you.
Check other cold/flu medicines you are taking to avoid duplicate dextromethorphan dosing.
Stay well hydrated and rest to support recovery from the underlying cold.
See a doctor if the cough lasts more than about a week or is accompanied by fever or breathlessness.
