Benylin Dry Coughs Night Syrup 150ml is a night-time cough medicine designed to provide relief from persistent, dry and irritating coughs that can make it difficult to rest. Its combination of three active ingredients helps suppress the urge to cough, relieve associated discomfort and aid restful sleep.

A dry cough, sometimes called a non-productive cough, occurs when you cough without bringing up mucus or phlegm. It can cause repeated bouts of coughing, an uncomfortable tickling sensation in the throat and irritation that becomes particularly troublesome at bedtime.

Benylin Dry Coughs Night Syrup contains dextromethorphan hydrobromide, diphenhydramine hydrochloride and levomenthol. These ingredients work in different ways to provide symptomatic relief.

How Does Benylin Dry Coughs Night Work?


Dextromethorphan hydrobromide is a cough suppressant that acts on the cough reflex to help reduce the frequency of dry, irritating coughing. It is particularly relevant when there is little or no mucus to clear.

Diphenhydramine hydrochloride is a first-generation antihistamine with cough-relieving and sedating properties. It contributes to symptom relief and may cause drowsiness, which can help when coughing interferes with rest. Because it affects alertness, the medicine should not be used simply as a sleeping aid.

Levomenthol provides a cooling sensation and helps relieve the feeling of nasal stuffiness that may accompany coughs and colds.

Together, these ingredients offer a night-time treatment option for people experiencing persistent dry cough symptoms.

Benefits of Benylin Dry Coughs Night Syrup

  • Relieves persistent dry coughs: Contains dextromethorphan to help suppress the cough reflex.
  • Soothes troublesome night-time symptoms: Helps reduce irritating coughing that can interfere with rest.
  • Aids restful sleep: Contains diphenhydramine, which has sedating properties.
  • Helps relieve nasal stuffiness: Levomenthol provides a cooling sensation associated with relief from nasal congestion.
  • Convenient liquid formulation: The 150ml syrup can be measured using a suitable medicine-measuring device.

What Type of Cough Is It Suitable For?


Benylin Dry Coughs Night Syrup is intended for persistent, dry and irritating coughs, particularly when symptoms are troublesome at night.

It may be suitable if you experience a tickly throat, repeated bouts of dry coughing or difficulty settling down because of an irritating cough.

This medicine is not designed to loosen chest mucus. If your cough produces significant amounts of phlegm, a different treatment may be more appropriate. Ask a pharmacist for advice if you are unsure whether your cough is dry or chesty.

Who Can Use Benylin Dry Coughs Night?


Benylin Dry Coughs Night Syrup is intended for adults and children aged 12 years and over.

It is not suitable for children under 12 years.

The medicine contains a sedating antihistamine and a cough suppressant, so additional precautions apply to people with certain medical conditions or those taking other medicines.

In particular, it must not be taken with certain antidepressants, including selective serotonin reuptake inhibitors (SSRIs) or monoamine oxidase inhibitors (MAOIs). It should also not be combined with other cough and cold treatments without professional advice.

Does Benylin Dry Coughs Night Cause Drowsiness?


Yes. Benylin Dry Coughs Night contains diphenhydramine, which can cause drowsiness, dizziness and reduced alertness.

Avoid drinking alcohol while taking this medicine. Do not drive or operate machinery if affected.

Although the medicine can aid restful sleep, its purpose is to relieve cough symptoms rather than act as a general sleeping medicine.

When Should You Seek Medical Advice?


Consult a doctor or pharmacist if your cough persists, worsens or keeps returning.

Seek medical advice before use if you have asthma, chronic bronchitis, emphysema, a persistent cough or a cough producing excessive mucus.

Seek urgent medical attention if you develop significant breathing difficulties, severe chest pain or other serious symptoms.

Benylin Dry Coughs Night provides symptomatic relief and does not treat the underlying cause of a respiratory infection.
