Warnings and precautions
Older antihistamines cause marked drowsiness — do not drive or operate machinery until you know how this affects you. Tell your doctor promptly about any change in mood, sleep, agitation or unusual thoughts while taking montelukast; this is uncommon but recognised. This relieves the symptoms of an allergy; it does not treat the cause, and it is not a treatment for an acute asthma attack. Seek emergency care for swelling of the lips, tongue or throat, or difficulty breathing.
Do not take Winolap DS if
Not for anyone with a known allergy to this medicine or to any ingredient in the pack. The sedating antihistamines are not suitable for very young children, or for people with glaucoma or an enlarged prostate, without medical advice.
Interactions with other medicines
Alcohol, sleeping tablets and other sedating medicines add to the drowsiness. Tell your doctor about all cold and cough preparations — many already contain an antihistamine.
How to store Winolap DS
Store below 30°C in the original pack, away from direct sunlight and moisture. Keep out of the reach of children.
Expert advice for Winolap DS
Taking it at bedtime reduces the impact of any drowsiness. Identify and avoid your triggers where you can — dust, pollen, cold air.
