Do I need a prescription to buy Sunward Zorax 5% Cream?

No. Sunward Zorax 5% Cream is a non-prescription product and can be ordered without a prescription. It is still dispensed by a registered pharmacist on DoctorOnCall.

What pack sizes does Sunward Zorax 5% Cream come in?

It is supplied in a pack size of 5g. 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 Sunward Zorax 5% Cream 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 Sunward Zorax 5% Cream?

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 Sunward Zorax 5% Cream 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 Sunward Zorax 5% Cream?

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 Sunward Zorax 5% Cream 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 Sunward Zorax 5% Cream 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

Sunward Zorax 5% Cream is supplied as a cream, with Aciclovir (acyclovir) 5%. It is supplied in a pack size of 5g.

No prescription is required for this product, as it is a non-prescription medicine. This page is limited to product, safety and handling information.

Directions for Use

Wash your hands before and after use, and apply a thin layer of Sunward Zorax 5% Cream to the affected area as soon as you notice early symptoms such as tingling, itching, or redness. Gently rub the cream in and avoid contact with the eyes, inside the mouth, and other mucous membranes.

Dosage

Apply the cream to the affected area 5 times a day, at roughly 4-hour intervals, for 4 to 5 days; if the cold sore has not healed by then, continue for a further few days, up to a maximum of 10 days of use. Start treatment as early as possible for the best results, ideally at the first sign of tingling before blisters appear.

Relevant Information

Cold sores are caused by a virus that remains dormant in the body between outbreaks, often triggered by stress, sunlight, fever, or a weakened immune system, so topical aciclovir treats the current outbreak rather than curing the underlying infection. Frequent recurrences, or cold sores in someone with a weakened immune system, may need assessment by a doctor to consider additional or oral antiviral treatment.
