  • Usually taken once a day

How Longifene Syrup works

Cyproheptadine blocks the chemical messengers your body releases during an allergic reaction, which relieves sneezing, a running nose, watering eyes and itching.

How to take Longifene Syrup

Shake well before use, give the prescribed dose, can be taken with or without food

Take it exactly as your doctor prescribed. Do not change the dose or stop early on your own.

Missed dose and overdose

If you miss a dose

Take it as soon as you remember. If your next dose is almost due, skip the one you missed — never take two doses together to catch up.

If you take too much

An overdose of this medicine can cause severe drowsiness, a fast heartbeat, confusion and, in children, agitation and fits. Do not wait for symptoms to appear — go to the nearest emergency department and take the pack or strip with you.

Side effects of Longifene Syrup

Most side effects of Longifene are mild and settle as the body adjusts. Reported side effects include:

  • Drowsiness
  • Dry mouth
  • Headache
  • Tiredness
  • Nausea

Stop the medicine and seek help immediately for a rash, swelling of the face or lips, wheezing or difficulty breathing. Tell your doctor about any side effect that persists or worries you.

PregnancyConsult your doctor before using this in pregnancy.
BreastfeedingConsult your doctor before using this while breastfeeding.
AlcoholDo not drink alcohol while taking this medicine.
DrivingMay cause drowsiness or affect your concentration. Do not drive until you know how it affects you.
KidneyUse with caution if you have kidney disease — your doctor may adjust the dose or monitor your kidney function.
LiverUse with caution if you have liver disease — your doctor may adjust the dose or monitor your liver function.
Habit formingNo

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 Longifene 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 Longifene Syrup

Store below 30°C, away from direct sunlight. Do not freeze. Once opened, use it within the period printed on the pack. Keep out of the reach of children.

Expert advice for Longifene Syrup

Taking it at bedtime reduces the impact of any drowsiness. Identify and avoid your triggers where you can — dust, pollen, cold air.
