Overview

Norfox 400mg Tablet is a prescription-only medicine (POM) that contains Norfloxacin 400mg. 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, Norfox 400mg 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 Norfox 400mg Tablet on an empty stomach, at least one hour before or two hours after meals, with a full glass of water, and drink plenty of fluids throughout the day to help flush the urinary tract. Avoid taking it at the same time as antacids, calcium, iron, or zinc supplements, as these reduce its absorption.

Dosage

The usual dose of Norfox 400mg Tablet for adults is 400mg taken twice daily, with the course length depending on the type and severity of infection being treated. Your doctor will determine the correct dose and duration for your condition, and it is important to complete the full course even if symptoms improve early.

Drug / Food Interactions

Antacids, and calcium, iron, magnesium, or zinc supplements significantly reduce norfloxacin absorption – space doses at least 2 hours apart
NSAIDs (e.g. ibuprofen) taken together may increase the risk of central nervous system effects, including seizures
Warfarin’s blood-thinning effect may be enhanced, requiring closer INR monitoring
Theophylline blood levels may increase, raising the risk of theophylline-related side effects

Why is there no information here about what Norfox 400mg 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 Norfox 400mg Tablet?

Take it exactly as written on your prescription label. Do not increase, reduce or skip doses on your own, and do not continue beyond the period your doctor has prescribed. Practical handling steps are set out in 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 Norfox 400mg Tablet?

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 Norfox 400mg 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 Norfox 400mg 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 Norfox 400mg 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 Norfox 400mg 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.
