Overview
Sedilix-Rx Linctus is supplied as a healthcare product, with Promethazine – the sedating antihistamine and cough-suppressant component of this combination linctus. 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
Take Sedilix-Rx Linctus exactly as prescribed by your doctor, using the measuring cup or spoon provided rather than a regular household spoon, to ensure an accurate dose. Because it commonly causes drowsiness, your doctor may advise taking it in the evening or at bedtime.
Dosage
Your doctor will determine the appropriate dose and frequency based on your age, symptoms, and medical history; this should be followed exactly as prescribed and never exceeded. Do not give this medicine to children unless specifically prescribed for them, as sedating antihistamine-based linctus preparations require particular caution in younger age groups.
Shelf Life
Sedilix-Rx Linctus is generally stable until the expiry date printed on the bottle and carton when unopened and stored correctly. Once opened, check the label or ask your pharmacist for the recommended in-use period, and do not use the linctus past its expiry date.
Storage Instructions
Store below 25°C in a cool, dry place away from direct sunlight, and keep the bottle tightly closed between doses. Keep out of the sight and reach of children at all times, given the sedative nature of this medicine.
Side Effects
- Drowsiness or dizziness
- Nausea or vomiting
- Stomach discomfort
- Mild confusion (especially at high doses)

Contraindications
- Known hypersensitivity to promethazine or other antihistamines
- Young children, in whom promethazine-based linctus preparations require particular caution due to the risk of sedation and breathing-related effects

Quick Tips
- Avoid alcohol while taking this medicine, as it increases drowsiness
- Do not drive or operate machinery until you know how the medicine affects you
- Take it exactly as prescribed and do not adjust the dose without speaking to your doctor

Why is there no information here about what Sedilix-Rx Linctus 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 Sedilix-Rx Linctus?
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 Sedilix-Rx Linctus 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 Sedilix-Rx Linctus?
Store below 25°C in a cool, dry place away from direct sunlight, and keep the bottle tightly closed between doses. Keep out of the sight and reach of children at all times, given the sedative nature of this medicine. 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 Sedilix-Rx Linctus?
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 Sedilix-Rx Linctus 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 Sedilix-Rx Linctus 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.

Relevant Information
Because Sedilix-Rx Linctus is prescription-only, ongoing use should be guided by your doctor, particularly in children, the elderly, and anyone with existing medical conditions, as these groups are more sensitive to the sedative and anticholinergic effects of promethazine. If your cough persists beyond the period advised by your doctor or is accompanied by fever, breathlessness, or chest pain, seek medical review rather than continuing the linctus alone.
