Sunward Dimenhydrinate 15mg/5ml Syrup

Sunward Dimenhydrinate 15mg/5ml Syrup is an oral liquid antihistamine medicine formulated for children who experience motion sickness during travel by car, boat, train or air. Its active ingredient, dimenhydrinate, is a well-established over-the-counter option used to prevent and relieve the nausea, vomiting and dizziness that can occur with motion sickness, and it is also sometimes used more generally to settle mild dizziness of vestibular origin.

Available without a prescription in Malaysia, this syrup is specially suited to younger children who find it difficult to swallow tablets. It comes in a pleasant-tasting liquid form together with a measuring device to help caregivers give an accurate dose, making it a convenient option for family trips, school outings and other journeys where motion sickness may be a concern.

Dimenhydrinate works by blocking histamine (H1) receptors and dampening signals from the vestibular system of the inner ear to the part of the brain that controls nausea and vomiting. By calming this pathway, it helps prevent the queasy, dizzy and unsettled feeling that motion sickness triggers, and can also ease these symptoms once they have already started, though it works best when given before travel begins.

Shake the bottle well before use and measure the dose using the measuring cup or spoon provided rather than an ordinary household spoon. For best results, give the dose about 30 minutes to 1 hour before travel begins, and repeat only as advised on the product label or by a pharmacist, generally every 6 to 8 hours if needed. Always follow the age-appropriate dosing instructions on the packaging or as directed by a doctor or pharmacist.

Dosing is based on the child’s age and body weight, and caregivers should always refer to the dosing chart on the product packaging or seek advice from a pharmacist before giving this syrup to a child. This medicine is generally not recommended for children under 2 years of age unless a doctor has specifically advised it, and the maximum daily dose stated on the label should never be exceeded.

When stored correctly and unopened, this syrup typically remains stable until the expiry date printed on the bottle and outer carton. Always check this date before use and do not use the product beyond its stated expiry.

Store below 30°C in a cool, dry place away from direct sunlight and moisture, and keep the bottle tightly closed when not in use. Keep this medicine out of the reach and sight of children, and do not use it if the liquid has changed in colour, smell or consistency.

Motion sickness in children is common and usually harmless, arising from a mismatch between what the eyes see and what the inner ear senses during movement. While this syrup can help manage symptoms for occasional travel, parents should seek medical advice if a child experiences persistent vomiting, signs of dehydration, or motion sickness that occurs very frequently, as these may warrant further evaluation.
