Kep-Bl Syrup is used for treatment of Cough Treatment of Common cold.
Medically reviewed by Dr. Balaji Krishnan, MBBS · Updated September 2026
Kep-Bl Syrup contains Dextromethorphan Hydrochloride (10mg) + Bilastine (3.3mg) + Phenylephrine (5mg). It belongs to the Expectorant / mucolytic / bronchodilator and Antihistamine / leukotriene antagonist class of medicines.
Treatment of Cough Treatment of Common cold
Kep BL Syrup is a combination of three medicines: Dextromethorphan hydrochloride, bilastine, and phenylephrine. Dextromethorphan hydrochloride suppresses the cough reflex by acting on the brain's cough center. Bilastine blocks histamine receptors to reduce allergy symptoms like sneezing and runny nose. Phenylephrine narrows blood vessels in the nasal passages to relieve congestion and improve breathing. Together, these three components work together to relieve cough, allergy symptoms, and nasal congestion, providing comprehensive relief from cold symptoms.
Take this medicine in the dose and duration as advised by your doctor. Check the label for directions before use. Measure it with a measuring cup and take it by mouth. Shake well before use. Kep BL Syrup may be taken with or without food.
Take it exactly as your doctor prescribed. Do not change the dose or stop early on your own.
If you miss a dose of Kep BL Syrup, take it as soon as possible. However, if it is almost time for your next dose, skip the missed dose and go back to your regular schedule. Do not double the dose.
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 Kep-Bl 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.

See a doctor if a cough lasts more than a week, or comes with fever, breathlessness, chest pain or blood in the sputum. Do not give cough and cold preparations to young children except on a doctor's advice. Do not combine two cough preparations — they frequently contain the same ingredients, and the doses add up. Preparations containing codeine can cause dependence and must be used only for the period your doctor specifies. 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.
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.
Sedating ingredients add to the effect of alcohol and sleeping tablets. Decongestants such as phenylephrine and pseudoephedrine can raise blood pressure — tell your doctor if you are hypertensive. 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.
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.
Always stick to the dosage recommended by your doctor. Overdosing can lead to unwanted side effects, while underdosing may reduce the effectiveness of the treatment. Kep BL Syrup may cause drowsiness or dizziness, so avoid driving or operating heavy machinery until you know how the medication affects you. Avoid consuming alcohol while taking Kep BL Syrup as it can intensify the drowsiness and dizziness caused by the medication. Kep BL Syrup may cause dry mouth, drink plenty of water to stay hydrated while using the medication. This medicine is generally intended for short-term relief of cold and cough symptoms. If symptoms persist beyond a few days or worsen, consult your doctor for further evaluation.
