Do I need a prescription to buy Mucoprom Syrup?

What does Mucoprom Syrup contain?

Mucoprom Syrup is a syrup containing Promethazine Hydrochloride. The full ingredient list is shown in the Composition or Ingredients section on this page and on the product packaging.

What pack sizes does Mucoprom Syrup come in?

It is supplied in a pack size of 120ml. Choose the pack size you need from the options shown on this page before adding the item to your cart.

Why is there no information here about what Mucoprom 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 Mucoprom 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 Mucoprom 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 Mucoprom 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 Mucoprom 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 Mucoprom 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

Mucoprom Syrup is a syrup with Promethazine Hydrochloride declared as its active content. It is supplied in a pack size of 120ml.

This is a non-prescription product and can be purchased without a prescription. Only product, safety and handling details are published on this page.

An online consultation with a DoctorOnCall doctor or pharmacist is available for this product, and a registered pharmacist reviews each order before dispatch to Malaysia or Singapore. Follow the directions on the label and on the leaflet inside 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. Mucoprom Syrup may be taken with or without food, and because it commonly causes drowsiness, it is often best taken in the evening or before bedtime unless your pharmacist or doctor advises otherwise; avoid alcohol and do not drive or operate machinery until you know how the syrup affects you.

Dosage

Dosing is based on age and should follow the product label or your pharmacist’s or doctor’s advice, as promethazine syrup is generally not recommended for children under 2 years of age due to the risk of severe breathing problems. Adults and older children are typically given a measured dose every 4 to 6 hours as needed, without exceeding the maximum daily amount stated on the packaging, and the lowest effective dose should be used for the shortest time needed to control symptoms.

Shelf Life

Mucoprom Syrup remains effective until the expiry date printed on the bottle and 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 if the printed expiry date has not yet passed.

Storage Instructions

Store Mucoprom Syrup below 30°C in a cool, dry place away from direct sunlight and moisture, and keep the bottle tightly closed after use. Do not refrigerate or freeze unless the label specifically states otherwise, and keep the syrup out of reach and sight of children at all times.

Side Effects

Drowsiness or dizziness
Dry mouth
Blurred vision
Constipation
Skin sensitivity to sunlight
Confusion (especially in older adults)
Restlessness in children

Contraindications

Known hypersensitivity to promethazine or other phenothiazine-type medicines
Children under 2 years of age, due to the risk of severe or life-threatening breathing problems
Narrow-angle glaucoma
Severe liver disease
Use together with other strong sedating medicines or alcohol without medical advice
A history of severe asthma or breathing difficulty, where sedating antihistamines should be used with caution

Drug / Food Interactions

Alcohol, which can significantly increase drowsiness and impair coordination
Other sedating antihistamines, sleeping tablets, 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
Medicines for anxiety, depression, or pain that also cause drowsiness

Quick Tips

Avoid driving or operating machinery until you know how this syrup affects your alertness
Do not combine with alcohol or other sedating medicines
Taking the dose in the evening can help minimize daytime drowsiness
Keep well hydrated and use a humidifier if the air is dry, as this can ease throat irritation
See a doctor if your cough lasts longer than about a week, worsens, or is accompanied by fever, chest pain, or coloured phlegm

Relevant Information

Mucoprom Syrup is sold as a non-prescription pharmacy medicine in Malaysia for short-term relief of dry cough and allergy-related symptoms, but because promethazine causes significant sedation and is not suitable for very young children, it is advisable to check with a pharmacist before giving it to children, the elderly, or anyone already taking other sedating medicines.
