Covonia Night Time Formula is an over-the-counter sedating night-time cough and cold syrup manufactured by Thornton & Ross. Each 20ml night dose contains two active ingredients: Dextromethorphan Hydrobromide (20mg) and Diphenhydramine Hydrochloride (50mg) in a soothing liquid base.
Taken by mouth at bedtime, adults and teenagers aged 12 and over use it for the night-time relief of dry, tickly coughs and restless symptoms of colds, helping to calm irritating coughs so you can sleep comfortably.
Night-time coughs can ruin restful sleep. Covonia Night Time Formula combines two proven active ingredients to tackle nighttime symptoms:
Dextromethorphan (Cough Suppressant): Acts on the cough control center in the brain to block the continuous, involuntary urge to cough up dry tickles.
Diphenhydramine (Sedating Antihistamine): Eases runny nose, sneezing, and watery eyes while providing a calming, drowsy effect that helps you fall asleep despite cold symptoms.
Soothes Throat: The thick liquid formula coats raw, irritated throat tissues to calm tickling sensations.
🚨 Critical Safety Warning: This medicine will make you drowsy.
Do NOT drive, operate heavy machinery, or carry out tasks that require mental alertness after taking this syrup.
Avoid drinking alcohol or taking other sedating medicines while taking this syrup, as this can cause dangerous levels of sleepiness or slow breathing.
🚨 Dangerous Interaction Warning: Do NOT take this medicine if you are taking, or have taken in the last 14 days, Monoamine Oxidase Inhibitors (MAOIs) or SSRIs for depression. Combining dextromethorphan with these medications can lead to a severe, life-threatening condition called serotonin syndrome.
Night-Time Use Only: Designed specifically for bedtime use to relieve overnight symptoms.
Asthma & Respiratory Conditions: Do NOT take if you have chronic bronchitis, emphysema, or during an acute asthma attack.
Prostate & Glaucoma Caution: Consult your doctor before use if you have narrow-angle glaucoma or prostate enlargement (difficulty urinating).
Age Limit: Suitable for adults and children aged 12 years and older. Do NOT give to children under 12 years of age.
Pregnancy and Breastfeeding: Do NOT take this medicine if you are pregnant or breastfeeding.
Shake Well: Always shake the bottle thoroughly before measuring your dose.
Dose: Take one 20ml dose (or four 5ml spoonfuls) at bedtime.
Frequency: Take only once a night at bedtime.
Duration: Do not use continuously for more than 7 days. If your cough persists longer, see a doctor.
Covonia Night Time Formula is generally well-tolerated when used at night as directed, but side effects can include:
Drowsiness, grogginess, or feeling "hungover" the next morning.
Dry mouth, nose, or throat.
Mild dizziness, blurred vision, or stomach upset.
Difficulty urinating in elderly patients or men with prostate issues.
Can I take Covonia Night Time Formula during the daytime?
No. This formula contains a sedating antihistamine designed specifically to help you sleep at night. Taking it during the day can cause severe drowsiness and impair your ability to perform daily tasks safely.
What should I do if my cough produces thick phlegm?
This syrup is formulated specifically for dry, tickly, non-productive coughs. If you have a chesty cough with heavy phlegm, suppressing it can trap mucus in your lungs; consult a pharmacist for an expectorant formula instead.
How should I store this syrup safely?
Keep the bottle tightly capped inside its original box to protect it from light. Store in a cool, dry place strictly below 25°C or 30°C, away from direct heat, and keep completely out of reach of children.
