Sunward Sunadine Syrup

Sunward Sunadine Syrup is an over-the-counter antihistamine syrup containing loratadine, used to relieve the symptoms of allergic conditions such as allergic rhinitis (hay fever) and chronic urticaria (hives). It helps ease sneezing, a runny or itchy nose, itchy and watery eyes, and itchy skin caused by allergies, including both seasonal and year-round (perennial) allergic rhinitis.

Loratadine is a second-generation, low-sedation antihistamine that works by blocking the action of histamine, a chemical the body releases during an allergic reaction. This syrup formulation is often preferred for children and adults who have difficulty swallowing tablets, and it is available as a non-prescription (OTC) product at DoctorOnCall.

Loratadine selectively blocks peripheral histamine H1-receptors, preventing histamine from binding and triggering the typical allergy symptoms of sneezing, itching, and nasal or eye discharge. Because it does not readily cross into the brain at normal doses, it is considered a low-sedation antihistamine compared with older, first-generation options.

Shake the bottle well before use and measure the dose accurately with the measuring cup or oral syringe provided, rather than an ordinary household spoon. The syrup can be taken with or without food, once daily, and is best taken at the same time each day for consistent symptom control.

The dose depends on age and body weight, so always check the product label or ask a pharmacist for the correct amount for adults, children, or the elderly. As a general guide, adults and children above the age stated on the label typically take a fixed dose once daily, while younger children require a lower, weight-adjusted dose, and use in very young infants should only be under medical advice.

Sunward Sunadine Syrup is generally stable for up to 2 to 3 years from the date of manufacture when unopened and stored correctly. Always check the expiry date printed on the bottle and discard any syrup that is past its expiry date or shows a change in colour, smell, or consistency.

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 out of the sight and reach of children.

• Known hypersensitivity to loratadine or any other ingredient in the syrup
• Severe liver impairment without dose adjustment guided by a doctor
• Use in infants below the minimum age stated on the product label unless directed by a doctor

• Ketoconazole, erythromycin, and cimetidine, which may increase loratadine blood levels
• Alcohol, which may add to feelings of drowsiness in some individuals
• Other antihistamines or cold and allergy products, to avoid duplicate dosing
• Grapefruit juice, which some references note may affect antihistamine metabolism

• Take the dose at the same time every day to keep allergy symptoms consistently under control
• Loratadine is generally considered low-sedation, but observe how it affects you before driving or operating machinery
• Identify and avoid known allergy triggers such as dust, pollen, or pet dander where possible
• Do not exceed the recommended daily dose even if symptoms feel severe
• See a doctor if symptoms persist beyond a few weeks or worsen despite regular use

Sunward Sunadine Syrup is intended for the relief of allergy symptoms and is not a cure for the underlying allergic condition. Customers in Malaysia and Singapore who are pregnant, breastfeeding, elderly, or have liver disease should consult a doctor or pharmacist before use, and parents should confirm the minimum age and correct dose on the label before giving it to a child.
