Overview

Ketosteril Tablet is a prescription-only medicine (POM) that contains Calcium 3-methyl-2-oxovalerate (ketoanalogue of isoleucine), Calcium 4-methyl-2-oxovalerate (ketoanalogue of leucine), Calcium 2-oxo-3-phenylpropionate (ketoanalogue of phenylalanine), Calcium 3-methyl-2-oxobutyrate (ketoanalogue of valine), Calcium DL-2-hydroxy-4-methylthiobutyrate (ketoanalogue of methionine) and L-lysine acetate, L-threonine, L-tryptophan, L-histidine, and L-tyrosine. It is supplied as a tablet and is dispensed in Malaysia only against a valid prescription issued by a registered doctor.

Under Malaysian rules for prescription medicines, this page carries product, safety and handling information only. Your doctor or pharmacist will explain whether this medicine is suitable for you, the dose you should take, and how long you should take it.

On DoctorOnCall, Ketosteril Tablet is reviewed by a licensed doctor through an online consultation and dispensed by a registered pharmacist before delivery. Always follow the instructions on your prescription label and the package insert supplied with the product, and do not share this medicine with anyone else.

Directions for Use

Take Ketosteril Tablet together with meals, swallowing the tablets whole without chewing, spread evenly across your main meals as directed by your care team. This medicine works as part of a supervised low-protein diet plan – it is not a substitute for the dietary protein restriction your nephrologist or dietitian has prescribed, and both must be followed together for it to be effective.

Dosage

Ketosteril Tablet is typically dosed according to body weight, as a guide around 1 tablet per 5kg of body weight per day, divided across the main meals of the day. Your nephrologist or renal dietitian will set the exact number of tablets based on your kidney function, body weight, and the level of protein restriction in your prescribed diet, and this regimen should never be adjusted on your own.

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.

Side Effects

  • Mild gastrointestinal discomfort
  • Nausea
  • Abdominal bloating
  • Loss of appetite
  • Metallic taste in mouth

Contraindications

  • Known hypersensitivity to any ketoanalogue, amino acid, or excipient in this product
  • Elevated blood calcium levels (hypercalcaemia)
  • Disorders of amino acid metabolism
  • Use without a doctor- or dietitian-supervised low-protein diet, as the two are intended to work together

Drug / Food Interactions

  • Calcium-containing supplements, antacids, or vitamin D may add to this product’s calcium content and increase the risk of high blood calcium
  • Tetracycline antibiotics and some other oral medicines may bind to the calcium salts in this product, reducing their own absorption if taken at the same time – space doses apart as advised
  • Phosphate binders and other renal diet supplements should only be combined under medical supervision, as your overall mineral intake needs to be balanced
  • This product must be used alongside, not instead of, the specific low-protein diet prescribed by your renal team

Quick Tips

  • Take your tablets with meals as instructed, spread across the day rather than all at once
  • Follow your prescribed low-protein renal diet closely – this medicine works together with, not in place of, that diet
  • Attend all scheduled blood tests to monitor kidney function and calcium levels
  • Do not add extra calcium or vitamin D supplements without checking with your doctor first

Frequently Asked Questions

Is Ketosteril Tablet a prescription medicine?

Yes. Ketosteril Tablet is a prescription-only medicine (POM). It can only be supplied against a valid prescription written by a registered doctor, and it should be used only by the person named on the prescription label.

What does Ketosteril Tablet contain?

Ketosteril Tablet is supplied as a tablet and contains Calcium 3-methyl-2-oxovalerate (ketoanalogue of isoleucine), Calcium 4-methyl-2-oxovalerate (ketoanalogue of leucine), Calcium 2-oxo-3-phenylpropionate (ketoanalogue of phenylalanine), Calcium 3-methyl-2-oxobutyrate (ketoanalogue of valine), Calcium DL-2-hydroxy-4-methylthiobutyrate (ketoanalogue of methionine) and L-lysine acetate, L-threonine, L-tryptophan, L-histidine, and L-tyrosine. The full composition is listed in the Composition section on this page and on the product packaging.

Why is there no information here about what Ketosteril 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 Ketosteril 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 Ketosteril Tablet?

Store below 30°C in a dry place, away from direct sunlight and out of reach of children. Keep it in the original pack until use, and do not use it after the expiry date printed on the packaging.

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 Ketosteril 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 Ketosteril 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 Ketosteril 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 Ketosteril 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.
