Overview

Glucophage 1000mg Tablet is supplied as a tablet, with Metformin Hydrochloride 1000mg. It is supplied in pack sizes of 120s and 15s.

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

If you would like guidance before buying, you can speak to a doctor or pharmacist through an online consultation on DoctorOnCall. Orders are dispensed by a registered pharmacist and delivered to your address.

Directions for Use

Glucophage 1000mg Tablet should be taken exactly as prescribed, generally with or immediately after a main meal to reduce stomach-related side effects. At this higher strength, doctors commonly split the daily dose across two meals rather than giving it all at once, so patients should follow their specific dosing schedule rather than assuming a single daily dose. Tablets should be swallowed whole with water and not crushed or chewed unless the doctor has specifically advised otherwise.

Dosage

The dose of Glucophage 1000mg Tablet is individualised by the prescribing doctor based on blood glucose control, kidney function, and response to lower Metformin strengths used earlier in treatment. It is typically part of a total daily Metformin dose that is divided across two main meals rather than taken as a single 1000mg dose, and any adjustment should only be made by the doctor after reviewing blood glucose readings and, where relevant, kidney function tests.

Shelf Life

Glucophage 1000mg Tablet is generally stable until the expiry date printed on the blister or carton when stored under the recommended conditions. Do not use the tablets beyond the printed expiry date.

Storage Instructions

Store below 30°C in a dry place, protected from direct light and humidity, and keep tablets in their original blister packaging until they are needed. Keep out of the sight and reach of children at all times.

Side Effects

  • Nausea or vomiting
  • Diarrhea
  • Stomach discomfort or cramps
  • Metallic taste in the mouth
  • Loss of appetite
  • Weight loss (in some cases)

Contraindications

  • Known hypersensitivity to metformin
  • Moderate to severe kidney impairment, as assessed by the prescribing doctor
  • Acute conditions with risk of altered kidney function, such as severe dehydration, serious infection, or shock
  • Uncontrolled or decompensated heart failure, or acute or unstable heart failure
  • Conditions predisposing to tissue hypoxia, such as acute heart attack or severe respiratory failure
  • Planned use of iodinated contrast dye for imaging, unless timed by the doctor around the procedure

Drug / Food Interactions

  • Iodinated contrast media used in certain imaging scans — Metformin may need to be temporarily stopped around the procedure on your doctor’s advice
  • Alcohol — excessive intake increases the risk of lactic acidosis, especially with liver problems or fasting
  • Certain diuretics, corticosteroids, and other medicines that can affect kidney function or blood glucose control
  • Other glucose-lowering medicines or insulin — combined use may increase the risk of low blood sugar and requires monitoring
  • Take with food as directed, as this reduces gastrointestinal side effects

Quick Tips

  • Take Glucophage 1000mg Tablet exactly at the times and with the meals your doctor has specified, since the dose is often split across the day at this strength
  • Never double up a missed dose; simply continue with the next scheduled dose
  • Attend regular follow-ups so kidney function and blood glucose control can be monitored
  • Inform your doctor before any scan involving contrast dye or before surgery
  • Watch for unusual muscle pain, breathing difficulty, or severe tiredness, and seek medical attention promptly if these occur

Why is there no information here about what Glucophage 1000mg Tablet 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 Glucophage 1000mg 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 Glucophage 1000mg 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.

How should I store Glucophage 1000mg Tablet?

Store below 30°C in a dry place, protected from direct light and humidity, and keep tablets in their original blister packaging until they are needed. Keep out of the sight and reach of children at all times. Keep it in its original pack and do not use it after the expiry date printed on the packaging.

What should I do if I notice side effects after using Glucophage 1000mg Tablet?

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 Glucophage 1000mg 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 Glucophage 1000mg 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

Glucophage 1000mg Tablet is typically prescribed once a patient’s Metformin requirement has increased beyond the standard starting strengths, and it is usually part of a broader diabetes management plan that also includes diet, physical activity, and periodic blood tests. Because it is a higher tablet strength, doctors pay particular attention to kidney function before and during treatment, and any online consultation through DoctorOnCall will include a review of these factors before the prescription is confirmed or renewed.
