Why is there no information here about what Sensitamine 4mg 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 Sensitamine 4mg 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 Sensitamine 4mg 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.

What should I do if I notice side effects after using Sensitamine 4mg Tablet?

Stop using the product and speak to a doctor or pharmacist about any reaction that concerns you.

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 Sensitamine 4mg 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 Sensitamine 4mg 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

Sensitamine 4mg Tablet is a tablet with Chlorpheniramine Maleate 4mg declared as its active content. It is supplied in a pack size of 10s.

This is a non-prescription product and can be purchased without a prescription. Only product, safety and handling details are published on this page.

An online consultation with a DoctorOnCall doctor or pharmacist is available for this product, and a registered pharmacist reviews each order before dispatch to Malaysia or Singapore. Follow the directions on the label and on the leaflet inside the pack.

Directions for Use

Take Sensitamine 4mg Tablet by mouth with a glass of water, with or without food. Swallow the tablet whole and do not exceed the dose or frequency stated on the product label or advised by your pharmacist. Because it can cause drowsiness, avoid driving, cycling, or operating machinery until you know how the tablet affects you, and avoid alcohol while taking it.

Dosage

The usual dose for adults and adolescents aged 12 years and above is one 4mg tablet every 4 to 6 hours as needed, up to a maximum of 6 tablets (24mg) in 24 hours. This tablet form is generally intended for older children and adults who can safely swallow tablets; younger children needing chlorpheniramine should use a liquid formulation under a pharmacist’s or doctor’s guidance. Elderly users may need a lower dose due to increased sensitivity to sedative and anticholinergic effects.

Shelf Life

Unopened and stored correctly, Sensitamine 4mg Tablet is generally stable for up to 36 months from the manufacturing date. Always check the expiry date printed on the packaging or blister strip before use and discard any expired tablets.

Storage Instructions

Store below 30°C in a cool, dry place away from direct sunlight, and keep the tablets in their original blister packaging until you are ready to take them. Keep out of reach and sight of children.

Drug / Food Interactions

Relevant Information

Sensitamine 4mg Tablet contains chlorpheniramine maleate, a long-used and widely available antihistamine in Malaysia’s pharmacies. It is generally appropriate for short-term or as-needed allergy relief in adults and older children, but pregnant or breastfeeding women, elderly patients, and those with glaucoma, prostate enlargement, asthma, or liver or kidney conditions should seek pharmacist or doctor advice before use. Severe allergic reactions with breathing difficulty, facial or throat swelling, or widespread hives need urgent medical attention rather than self-treatment.
