What are Numark Menthol BP Crystals?

Numark Methol Crystals are a form of aromatherapy that works to help relieve a blocked or stuffy nose by working as a decongestant. The active ingredient is menthol, which is a plant extract that works to help you breathe easier and provide a cooling effect. Menthol is used in other treatments to help provide a cool effect, such as for anyone who is suffering from a fever. Menthol does not lower the body temperature itself.


What causes a blocked nose?

A blocked nose is usually caused by a virus, either a cold or the flu. The infection can often lead to the blood vessels in the nose and sinuses to be become enlarged, causing a blockage. An increase in the amount of mucus can also contribute to a blocked or stuffy nose.


Who are these menthol crystals suitable for?

These menthol crystals are suitable to be used by adults and children aged 16 and over. They should not be used by anyone who is allergic to menthol or has breathing difficulties or asthma. If you are using any other form of treatment for a blocked or stuffy nose, then speak to a doctor or Chemist 4 U pharmacist before using.


Can someone who is pregnant or breastfeeding use these crystals?

There is no known evidence of any issues when using these crystals when breastfeeding. However, if you are unsure, speak to a medical professional before using.


How should Numark Menthol BP Crystals be used?

Simply add a small number of crystals to a bowl of hot water and inhale the steam. Ideally, try to use this just before going to bed, as it will help you to get to sleep. For the best results, blow your nose before using. If a small number of crystals does not work, try increasing the number of crystals used gradually.


Are there any side effects?

There is unlikely to be any side effects unless there is an allergic reaction toward menthol. If you notice any side effect, stop using and speak to a doctor as soon as possible. You can also record a side effect using the MHRA Yellow Card Scheme.
