Why is there no information here about what Xepa Cough-En 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 Xepa Cough-En 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 Xepa Cough-En 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.

What should I do if I notice side effects after using Xepa Cough-En Linctus?

Stop using the product and speak to a doctor or pharmacist about any reaction that concerns you.

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 Xepa Cough-En 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 Xepa Cough-En 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.

Overview

Xepa Cough-En Linctus is a healthcare product with Diphenhydramine hydrochloride and Ammonium chloride 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

Take Xepa Cough-En Linctus by mouth using the measuring cup or spoon provided, shaking the bottle well beforehand, and space doses evenly through the day as directed on the label; because diphenhydramine can cause drowsiness, take extra care with the timing of doses if you need to drive or operate machinery afterward.

Dosage

Dosing is age-based and should follow the directions on the product label or a pharmacist’s advice — adults and older children are generally given a higher dose than younger children, taken several times a day as needed for cough, up to the maximum stated on the packaging. This linctus is not generally recommended for very young children without a doctor’s or pharmacist’s specific advice, and the dose should not be increased beyond the label directions.

Storage Instructions

Store below 30°C in a cool, dry place away from direct sunlight, keep the cap tightly closed between doses, and store out of the sight and reach of children.

Side Effects

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

Contraindications

Known hypersensitivity to diphenhydramine, ammonium chloride, or other ingredients in the linctus
Severe liver or kidney impairment (ammonium chloride is cleared via these organs) — seek medical advice first
Infants and very young children, unless specifically advised by a doctor or pharmacist

Drug / Food Interactions

Alcohol and other sedating medicines — increased drowsiness
Other antihistamine- or diphenhydramine-containing cold, flu, allergy, or sleep products — risk of double-dosing on the same active ingredient
MAOI antidepressants — may intensify anticholinergic and sedative effects

Quick Tips

Check other cold, flu, allergy or sleep products you’re taking to avoid duplicating diphenhydramine
Take care if you need to drive or operate machinery, as it can cause drowsiness
Stay well hydrated to help the expectorant action loosen mucus
Use the measuring cup or spoon provided for an accurate dose
Avoid alcohol while taking this linctus
See a doctor if the cough lasts more than a week, or is accompanied by fever, chest pain, or breathlessness
