Hova Expectorant

Hova Expectorant is a combination cough and cold syrup containing diphenhydramine hydrochloride 14mg, ammonium chloride 135mg, and sodium citrate dihydrate 57mg per 5mL. It is formulated to relieve coughs associated with excess mucus and chest congestion, combining an antihistamine (diphenhydramine) that helps suppress the cough reflex and reduce associated irritation, with expectorant ingredients (ammonium chloride and sodium citrate) that help loosen and thin mucus so it can be cleared more easily from the airways.

As Hova Expectorant is classified as a prescription medicine on DoctorOnCall, purchasing it requires an online consultation so a doctor can assess your suitability, confirm that a sedating antihistamine-containing cough preparation is appropriate for you, and issue a prescription before your order is dispensed.

Diphenhydramine is a sedating antihistamine that acts on the cough centre and reduces histamine-related irritation of the airway lining, helping to calm a troublesome cough, while ammonium chloride and sodium citrate act as expectorants that increase the water content and reduce the thickness of mucus in the airways, making it easier to cough up and clear.

Hova Expectorant should be taken by mouth using the dosing cup or spoon provided, shaking the bottle well before use, strictly according to the dose, frequency, and duration prescribed by your doctor following your online consultation; do not exceed the prescribed dose without further medical advice.

Dosage of Hova Expectorant is determined by your prescribing doctor based on your age and clinical need; as a sedating antihistamine-containing preparation it is not recommended for young children without medical advice, and adults should follow the doctor-prescribed dose and frequency precisely, typically taken several times a day with adequate spacing between doses.

Use Hova Expectorant within the expiry date printed on the bottle and carton, and discard any unused portion once this date has passed or as advised by your pharmacist after opening.

Store Hova Expectorant below 30°C in a cool, dry place away from direct sunlight and moisture, keep the bottle tightly closed, and keep out of reach and sight of children.

• Shake the bottle well before each use to ensure the dose is evenly mixed
• Avoid driving or operating machinery until you know how this syrup affects you, as drowsiness is common

• Drink plenty of water to help support the loosening effect on mucus
• See a doctor if your cough persists beyond a week, is accompanied by fever, or worsens

Hova Expectorant combines a sedating antihistamine with expectorant salts and is dispensed as a prescription item through DoctorOnCall. Because it contains a sedating antihistamine, it should be used with particular caution in the elderly and in anyone who needs to remain alert, and prescribing doctors should consider individual patient factors such as liver function before recommending use.
