Why is there no information here about what Detrusitol 2mg 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 Detrusitol 2mg Tablet?

Can I speak to a doctor or pharmacist about Detrusitol 2mg Tablet before I buy it?

What should I do if I notice side effects after using Detrusitol 2mg 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 Detrusitol 2mg 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 Detrusitol 2mg 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.

Overview

Detrusitol 2mg Tablet contains Tolterodine Tartrate 2mg and is presented as a tablet. It is supplied in pack sizes of 14s and 56s.

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

Detrusitol tablets should be swallowed whole with a glass of water, with or without food, and taken exactly as prescribed by your doctor, usually once or twice daily depending on the formulation and dose prescribed. It may take several weeks of consistent use to notice the full improvement in bladder symptoms, so treatment should not be stopped early without discussing it with your doctor.

Dosage

The usual adult starting dose is 2mg taken twice daily, which a doctor may adjust to 1mg twice daily depending on response and tolerability, particularly in patients with reduced liver function or those taking certain interacting medicines. Dosing should always follow your doctor’s specific instructions, and the medicine should not be taken more frequently or at a higher dose than prescribed.

Storage Instructions

Store below 30°C in a dry place away from direct sunlight and moisture, keeping tablets in their original packaging until ready to use. Keep out of reach of children.

Relevant Information

Detrusitol is used as part of an ongoing management plan for overactive bladder rather than a one-time fix, and it is often combined with bladder training techniques, fluid management, and lifestyle adjustments for better symptom control. Regular follow-up with your prescribing doctor helps ensure the medicine remains effective and well tolerated over time, and allows for dose adjustments if side effects occur or if symptoms change.
