Same salt, different brand — what does that mean?

A substitute contains the same active ingredient (salt), in the same strength, as Relent Cold Oral Drops. The medicine inside is the same — the brand name, manufacturer and price are what differ.

All medicines sold in India, branded or generic, must meet the quality standards set by the national drug regulator (CDSCO). A lower price does not mean lower quality.

Please confirm with your doctor or pharmacist before switching brands — they will check that the strength and form match your prescription.

Composition of Relent Cold Oral Drops

Relent Cold Oral Drops contains Phenylephrine (5mg) + Chlorpheniramine (2mg). It belongs to the Expectorant / mucolytic / bronchodilator and Antihistamine / leukotriene antagonist class of medicines.

Uses of Relent Cold Oral Drops

  • This medicine is used in the treatment of cough
  • chest congestion
  • common cold symptoms
  • allergic rhinitis
  • hives and skin allergy
  • itching and allergic asthma.

Key benefits

  • Eases a chesty cough
  • Helps clear congestion
  • Fast relief of sneezing
  • running nose and itching
  • Non-sedating options are available
  • Usually taken once a day

How Relent Cold Oral Drops works

This medicine combines 2 active ingredients: Phenylephrine and Chlorpheniramine. Phenylephrine loosens and thins the mucus in your airways so a cough clears it more easily, and eases the tightness that comes with congestion. Chlorpheniramine blocks the chemical messengers your body releases during an allergic reaction, which relieves sneezing, a running nose, watering eyes and itching.

How to take Relent Cold Oral Drops

Shake the bottle well before each dose and measure it with the cup, spoon or dropper supplied — a kitchen spoon is not an accurate measure. Take it with or after food. Follow the dose and the duration written on your prescription.

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 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.

Side effects of Relent Cold Oral Drops

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

  • Nausea
  • Vomiting
  • Stomach upset
  • Drowsiness
  • Tremor
  • Fast heartbeat
  • Dry mouth
  • Headache
  • Tiredness

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.

Warnings and precautions

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.

Do not take Relent Cold Oral if

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.

Interactions with other medicines

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.

How to store Relent Cold Oral Drops

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 Relent Cold Oral Drops

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.
