Overview
Clarinase 24hr Tablet is a prescription-only medicine (POM) presented as a tablet, with Loratadine 5mg and Pseudoephedrine sulfate 120mg (repeat-action) as its active ingredient content.
This page is limited to product, safety and handling information, in line with Malaysian rules on prescription medicine information for the public. Your prescriber or pharmacist is the right source for anything beyond that, together with the leaflet inside the pack.
Through DoctorOnCall, this product is supplied after an online consultation with a licensed doctor and a valid prescription, and it is checked by a registered pharmacist before dispensing. Take it exactly as prescribed, and speak to your doctor before stopping, changing the dose, or starting any other medicine alongside it.
Directions for Use
Take Clarinase 24hr Tablet once daily, with or without food, swallowing the tablet whole with water – do not crush, chew, or split the tablet, as this is a repeat-action formulation designed to release the decongestant gradually over 24 hours.
Dosage
The usual dose of Clarinase 24hr Tablet is one tablet once daily, providing symptom relief for up to 24 hours. Your doctor or pharmacist will advise on how long you can safely use this combination product, as the decongestant component is generally intended for short-term relief rather than continuous long-term use.
Shelf Life
Use this product before the expiry date stated on the packaging. Do not use the medicine if the expiry date has passed.
Storage Instructions
Store below 30°C in a dry place, away from direct sunlight and out of reach of children.

Contraindications

Drug / Food Interactions
- MAO inhibitors are contraindicated due to the risk of a dangerous rise in blood pressure (hypertensive crisis)
- Other decongestants or stimulant medicines increase the risk of cardiovascular side effects
- Pseudoephedrine may reduce the blood-pressure-lowering effect of antihypertensive medicines
- Alcohol or other CNS depressants may modestly increase drowsiness, though loratadine itself is largely non-sedating
Quick Tips

- Avoid taking this medicine close to bedtime if you notice it affects your sleep
- Check your blood pressure regularly if you have hypertension and are using this medicine
- Use only for the duration recommended by your doctor or pharmacist, as the decongestant is intended for short-term relief

Why is there no information here about what Clarinase 24hr Tablet is for?
Malaysian rules for prescription medicines limit public product pages to product, safety and handling information. Your doctor decides whether this medicine is appropriate for you and will explain it during your consultation, and your pharmacist can answer further questions when the medicine is dispensed.
How should I take Clarinase 24hr Tablet?
Follow your doctor’s instructions and the directions on the dispensing label without changing them. If anything on the label is unclear, check with your pharmacist before taking the first dose, and read the Directions for Use section on this page.
What should I do if I miss a dose?
Take it as soon as you remember, unless your next dose is nearly due. In that case skip the missed dose and carry on with your usual schedule. Never take two doses together to make up for a missed one. If you miss doses often, tell your doctor or pharmacist.
How should I store Clarinase 24hr Tablet?

What should I do if I notice side effects?
Tell your doctor or pharmacist about any reaction that concerns you, and 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.
Can I stop taking Clarinase 24hr Tablet on my own?
No. Speak to your doctor before stopping, pausing or changing the dose, even if you feel well or think you no longer need the medicine.
How do I get a prescription for Clarinase 24hr Tablet?
Customers in Malaysia can complete an online consultation with a DoctorOnCall doctor, who decides whether a prescription is appropriate, or upload a valid prescription already issued by their own doctor.
Orders going to Singapore are dispatched from Malaysia as an international delivery, so you need to hold a valid prescription or doctor’s letter for the medicine. Check the consultation and prescription upload options shown at checkout for your delivery address before placing the order.
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 Clarinase 24hr Tablet 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 Clarinase 24hr Tablet 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.
