Overview

Mucoease Plus Syrup contains Carbocisteine and Promethazine Hydrochloride and is presented as a syrup. It is supplied in a pack size of 120ml.

It is classified as a non-prescription medicine, so no prescription is needed to order it. Under Malaysian rules for medicine information, this page carries product, safety and handling information only.

You can consult a doctor or pharmacist online on DoctorOnCall about this product before or after you order. Every order is checked by a registered pharmacist before it is delivered. Always read the label and the leaflet supplied with the pack.

Directions for Use

Shake the bottle well before each use and measure the dose using the measuring cup or spoon provided rather than an ordinary household spoon, following the schedule and duration set out by your prescribing doctor. Because promethazine can cause noticeable drowsiness, this syrup is often best taken in the evening unless your doctor advises otherwise, and alcohol should be avoided while using it; do not drive or operate machinery until you know how it affects you.

Dosage

The dose, frequency, and duration of Mucoease Plus Syrup are determined by the prescribing doctor based on your age, body weight, and the severity of your symptoms, and should not be adjusted without medical advice. Because it contains promethazine, this combination is generally not used in very young children, and any missed dose should simply be skipped rather than doubled up at the next scheduled dose.

Shelf Life

Mucoease Plus Syrup remains effective until the expiry date printed on the bottle and outer carton when stored correctly and unopened. Once opened, check the label or ask your pharmacist for the recommended in-use period, and discard any syrup that has changed in colour, smell, or consistency even before the printed expiry date.

Storage Instructions

Store Mucoease Plus Syrup below 30°C in a cool, dry place away from direct sunlight and moisture, and keep the bottle tightly closed between uses. Do not freeze, and always keep the syrup out of the reach and sight of children.

Side Effects

  • Drowsiness or sleepiness
  • Dry mouth
  • Nausea or mild stomach upset
  • Dizziness
  • Headache
  • Mild allergic reactions (e.g., skin rash, itching)

Contraindications

  • Known hypersensitivity to carbocisteine, promethazine, or any other ingredient in the syrup
  • Children under 2 years of age, due to the risk of severe breathing problems with promethazine
  • Active peptic ulcer disease, due to the carbocisteine component
  • Narrow-angle glaucoma or severe liver disease
  • Use together with other strong sedating medicines or alcohol without medical advice

Drug / Food Interactions

  • Alcohol, which can significantly increase drowsiness and impair coordination
  • Other sedating antihistamines, sleep medicines, or central nervous system depressants
  • Monoamine oxidase inhibitors (MAOIs), which can intensify promethazine’s effects
  • Other anticholinergic medicines, which may add to dry mouth, blurred vision, or urinary retention
  • Cough suppressants that prevent effective coughing, which are generally avoided together with mucolytics as they can lead to mucus retention in the airways

Quick Tips

  • Complete the course as prescribed by your doctor, even if your cough starts to improve sooner
  • Avoid driving or operating machinery until you know how this syrup affects your alertness
  • Do not combine with alcohol or other sedating medicines
  • Stay well hydrated, as adequate fluid intake supports the mucolytic effect of carbocisteine
  • Return to your doctor if your cough worsens, you develop fever, breathlessness, or chest pain, or symptoms do not improve as expected

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 Mucoease Plus Syrup?

Can I speak to a doctor or pharmacist about Mucoease Plus 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.

How should I store Mucoease Plus Syrup?

Store Mucoease Plus Syrup below 30°C in a cool, dry place away from direct sunlight and moisture, and keep the bottle tightly closed between uses. Do not freeze, and always keep the syrup out of the reach and sight of children. Keep it in its original pack and do not use it after the expiry date printed on the packaging.

What should I do if I notice side effects after using Mucoease Plus 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 Mucoease Plus 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 Mucoease Plus 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.
