Phenylephrine (20mg) + Chlorpheniramine (8mg)
Coldact Capsule is used for common cold and flu symptoms such as fever, headache, body ache, runny/stuffy nose, sneezing and watery eyes (varies by variant).
Medically reviewed by Dr. Balaji Krishnan, MBBS · Updated September 2026
Coldact Capsule contains Phenylephrine (20mg) + Chlorpheniramine (8mg). It belongs to the Combination (analgesic/antipyretic + antihistamine + decongestant; varies by variant) class of medicines.
Coldact products typically combine an analgesic/antipyretic to reduce fever and pain with an antihistamine to reduce sneezing/runny nose and a decongestant to relieve nasal blockage. Exact mechanism depends on the specific Coldact capsule variant and its ingredients.
Take exactly as directed on the label or by a doctor. Usually taken after food with water; do not exceed the recommended daily dose. Avoid taking with other cold/flu medicines containing similar ingredients (especially paracetamol).
Take it exactly as your doctor prescribed. Do not change the dose or stop early on your own.
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.
An overdose of this medicine can cause vomiting, severe drowsiness, a racing heart and, with codeine, dangerously slow breathing. It 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.
Most side effects of Coldact are mild and settle as the body adjusts. Reported side effects include:
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.

Not for children unless advised by a doctor. Use caution in hypertension, heart disease, glaucoma, enlarged prostate/urinary retention, thyroid disease, liver disease, and asthma/COPD. May cause drowsiness; avoid driving/alcohol. Seek care if symptoms persist, high fever, rash, or breathing difficulty.
Not for anyone with a known allergy to this medicine or to any ingredient in the pack. Codeine-containing preparations are not for children, or for anyone with breathing difficulty. The sedating antihistamines are not suitable for very young children, or for people with glaucoma or an enlarged prostate, without medical advice.
MAO inhibitors (dangerous interaction), other sedatives/alcohol (increased drowsiness), antihypertensives (reduced effect), other sympathomimetics/decongestants (additive BP/heart rate rise), other paracetamol-containing products (overdose risk)
Store below 25°C in a dry place, protect from moisture and light, keep out of reach of children.
Drink plenty of water — it thins mucus better than any syrup. Steam inhalation helps congestion and costs nothing. Measure the dose with the cup supplied. Taking it at bedtime reduces the impact of any drowsiness. Identify and avoid your triggers where you can — dust, pollen, cold air.
