Why is there no information here about what Duovent Unit Dose Vials Nebuliser Solution 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 Duovent Unit Dose Vials Nebuliser Solution?

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 Duovent Unit Dose Vials Nebuliser Solution before I buy it?

What should I do if I notice side effects after using Duovent Unit Dose Vials Nebuliser Solution?

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 Duovent Unit Dose Vials Nebuliser Solution 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 Duovent Unit Dose Vials Nebuliser Solution 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

Duovent Unit Dose Vials Nebuliser Solution is a solution with Fenoterol hydrobromide declared as its active content. It is supplied in pack sizes of 4ml x10 and 4ml x60.

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

Duovent Unit Dose Vials must be used only with a nebuliser device as prescribed by the doctor. Each vial is typically opened and the solution added to the nebuliser chamber, sometimes diluted with saline as directed, and inhaled through a mouthpiece or mask over several minutes; it should never be swallowed or injected, and dosing must strictly follow the doctor’s instructions.

Dosage

The dose and frequency of nebulisation will be determined by the doctor based on the severity of symptoms, the patient’s age, and their response to treatment, and may differ between an acute flare-up and regular maintenance use; patients should not increase the frequency of use on their own even if symptoms feel poorly controlled, and should seek urgent medical review instead.

Storage Instructions

Store below 25 degrees Celsius, protected from light, in a cool, dry place, and keep out of reach of children; do not use vials that have changed colour or appear discoloured.

Side Effects

Dry mouth
Cough
Headache
Dizziness
Nausea
Blurred vision

Should be used with particular caution, and only under close medical supervision, in patients with heart disease, uncontrolled hyperthyroidism, or diabetes

Drug / Food Interactions

Other beta-agonist bronchodilators, which may increase the risk of cardiovascular side effects when combined
Beta-blockers, which may reduce the bronchodilator effect of fenoterol
Monoamine oxidase inhibitors (MAOIs) or tricyclic antidepressants, which may increase cardiovascular side effects
Other anticholinergic medicines, which may add to ipratropium’s effects
Corticosteroids or diuretics, which combined with fenoterol may increase the risk of low blood potassium

Quick Tips

Use only with a properly functioning nebuliser device as instructed by your doctor
Avoid letting the solution or mist contact the eyes, especially in patients at risk of angle-closure glaucoma
Rinse the mouth after use to reduce dryness and irritation
Seek urgent medical attention if breathlessness worsens despite nebulisation or if you need to use it more often than prescribed
Keep regular follow-up appointments so your doctor can review your asthma or COPD control

Relevant Information

Duovent Unit Dose Vials Nebuliser Solution is a prescription-only combination bronchodilator intended for doctor-supervised management of asthma and COPD, and ongoing monitoring is important because needing nebulisation more frequently than prescribed can be a sign of worsening disease control that requires urgent medical reassessment rather than simply repeating doses.
