Overview
Gentamicin-Pos 0.3% Eye Drop is supplied as eye drops, with Gentamicin sulfate equivalent to gentamicin 0.3% w/v. It is supplied in a pack size of 5ml.
No prescription is required for this product, as it is a non-prescription medicine. This page is limited to product, safety and handling information.
If you would like guidance before buying, you can speak to a doctor or pharmacist through an online consultation on DoctorOnCall. Orders are dispensed by a registered pharmacist and delivered to your address.
Directions for Use
Gentamicin-Pos 0.3% Eye Drop should only be used according to the dosage, frequency, and duration prescribed by your doctor following an online consultation with DoctorOnCall. Wash your hands before use, tilt your head back, gently pull down the lower eyelid to form a small pocket, and instil the prescribed number of drops into the pocket without letting the dropper tip touch the eye or eyelid. Close your eyes gently for a minute or two and apply light pressure to the inner corner of the eye to reduce drainage into the tear duct.
Dosage
The dosage of Gentamicin-Pos 0.3% Eye Drop is determined individually by your prescribing doctor based on the severity of the infection, and commonly involves instilling 1 to 2 drops into the affected eye every 4 hours, or as directed, with more frequent dosing sometimes prescribed for severe infections. Always follow the exact dose, frequency, and treatment duration given on your prescription rather than any general guidance, and complete the full course even if symptoms improve early.
Shelf Life
Gentamicin-Pos 0.3% Eye Drop is generally stable for up to 24 to 36 months from the date of manufacture when unopened and stored correctly. Once opened, ophthalmic drops are typically only safe to use for up to 4 weeks, after which any remaining product should be discarded regardless of the printed expiry date; always check the expiry date on the bottle before use.

Relevant Information
Gentamicin-Pos 0.3% Eye Drop is typically prescribed for a short, defined course to treat a confirmed or suspected bacterial eye infection, and is not effective against viral or allergic conjunctivitis. Some doctors prescribe the eye drop for daytime use and an ophthalmic ointment for use at night, as the ointment provides longer contact time during sleep. A doctor should be consulted if eye pain, vision changes, or symptoms persist beyond the prescribed treatment course.

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.
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.
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.
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.
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.
