Why is there no information here about what Voltaren SR 100mg Tablet is for?

How should I use Voltaren SR 100mg Tablet?

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 Voltaren SR 100mg Tablet 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 Voltaren SR 100mg Tablet?

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

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 Voltaren SR 100mg 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 Voltaren SR 100mg 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.

Directions for Use

Voltaren SR 100mg Tablet should be swallowed whole with a glass of water, preferably with or after food to reduce the chance of stomach irritation. Do not crush, chew, or break the tablet, as this can interfere with its sustained-release action and increase the risk of side effects. Take this medicine exactly as prescribed by your doctor and do not adjust the dose on your own.

Dosage

The dose and duration of treatment will be determined by your doctor based on your condition and response to treatment, typically one tablet (100mg) once daily. Your doctor may prescribe the lowest effective dose for the shortest duration necessary to control your symptoms, and periodic review is usually recommended for longer-term use.

Shelf Life

Check the expiry date printed on the blister strip or carton before use, and do not take this medicine after the expiry date. Do not use tablets that appear damaged, discoloured, or that have been removed from their original packaging for an extended period.
