Overview
Zolterol 100mg SR Tablet contains Diclofenac sodium 100mg and is presented as a tablet. It is supplied in a pack size of 10s.
It is classified as a non-prescription medicine, so no prescription is needed to order it. Under Malaysian rules for medicine information, this page carries product, safety and handling information only.
You can consult a doctor or pharmacist online on DoctorOnCall about this product before or after you order. Every order is checked by a registered pharmacist before it is delivered. Always read the label and the leaflet supplied with the pack.
Directions for Use
Zolterol 100mg SR Tablet should be swallowed whole with a full glass of water, ideally at the same time each day, and taken with or shortly after food to reduce the risk of stomach irritation. The tablet must not be crushed, chewed, or split, as doing so breaks the sustained-release matrix and can cause the full dose to be released at once instead of gradually over the day.
Dosage
The usual adult dose is one 100mg SR tablet once daily, taken at approximately the same time each day for consistent round-the-clock effect, or as advised by a pharmacist or doctor. The sustained-release formulation should not be split into partial doses, and it should be used at the lowest effective frequency needed to control ongoing joint or muscle symptoms.
Shelf Life
Zolterol 100mg SR Tablet generally has a shelf life of up to 3 years from the date of manufacture when unopened and stored correctly, and the exact expiry date is printed on the blister strip and outer carton.
Storage Instructions
Store Zolterol 100mg SR Tablet below 30°C in a cool, dry place away from direct sunlight and moisture, and keep it in its original packaging out of the reach and sight of children.
Side Effects
Common side effects may include:
- Stomach pain or discomfort
- Nausea or vomiting
- Indigestion or gas
- Headache or dizziness
- Skin rash or itching
- Swelling in hands or feet
Contraindications
- Active or history of peptic ulcer or gastrointestinal bleeding
- Known hypersensitivity to diclofenac, aspirin, or other NSAIDs, including asthma, wheezing, or hives triggered by these medicines
- Severe heart failure, kidney impairment, or liver impairment
- Third trimester of pregnancy
- Active, uncontrolled bleeding disorders
- Difficulty swallowing tablets whole, since the SR tablet must not be crushed or split
Drug / Food Interactions
- Increased bleeding risk when taken with anticoagulants such as warfarin
- Increased risk of stomach irritation and bleeding when combined with other NSAIDs, aspirin, or corticosteroids
- May reduce the effectiveness of ACE inhibitors, ARBs, and diuretics, and increase the risk of kidney impairment when combined
- May raise blood levels of methotrexate or lithium when taken together
- Increased risk of kidney problems when combined with ciclosporin
- Alcohol may increase the risk of stomach irritation during treatment
Quick Tips
- Swallow the SR tablet whole with food; do not crush, chew, or split it, as this disrupts the slow-release action
- Take it at roughly the same time each day for steady, round-the-clock relief
- Do not take an extra tablet to make up for a missed dose; take the next dose at the usual time
- Avoid taking with other diclofenac or NSAID products unless directed
- Stop use and seek medical advice if you notice black stools, vomiting blood, or persistent stomach pain
- Consult a pharmacist before use if you have a history of stomach ulcers, heart disease, high blood pressure, or kidney problems

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 Zolterol 100mg SR 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 Zolterol 100mg SR 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.

Relevant Information
Zolterol 100mg SR Tablet is a Poison List C medicine in Malaysia, dispensed over the counter by a registered pharmacist rather than requiring a doctor’s prescription. Its once-daily sustained-release design is intended for people with ongoing joint or muscle pain who prefer a single daily dose over taking a standard-release diclofenac tablet two to three times a day, and pharmacist counselling helps confirm this formulation is suitable and that the tablet is being swallowed correctly.
If pain remains poorly controlled despite once-daily use, or is accompanied by swelling, fever, or significant loss of movement, a doctor should be consulted to reassess the treatment plan rather than continuing self-medication indefinitely.
