What is Sudafed Decongestant Liquid?

This Sudafed Decongestant Liquid is a treatment that works to reduce nasal congestion that has been caused by a cold or the flu. As well as that, this treatment can also relieve catarrh, which is the build-up of mucus in the nose, chest, or throat. The active ingredient in this liquid is pseudoephedrine, which is a decongestant that works by thinning the blood vessels that have become swollen as a result of an infection.


What causes a blocked nose or catarrh?

Both a blocked nose and catarrh are caused by an infection, such as a cold or the flu. They can also be caused by an allergic reaction like hay fever. They occur as a result of germs entering the body and resting in the nose and mouth. The germs enter the body through the nose, mouth, or eyes after someone has sneezed or coughed and the germs linger in the air.


Who is this liquid suitable for?

This liquid is suitable to be used by adults and children aged 6 and over. It should not be used by anyone who is allergic to the ingredients contained in the liquid. This treatment should also not be used if any of the following applies to you:

  • Have high blood pressure or heart disease
  • Are diabetic
  • Have an overactive thyroid
  • Suffer from closed-angle glaucoma
  • Have severe kidney problems
  • Taking beta-blockers for high blood pressure
  • Taking antidepressants known as monoamine oxidase inhibitors (MAOIs)
  • Taking any other type of cough and cold medicine

If you are using any medication for another condition, speak to a doctor or Chemist 4 U pharmacist before using this liquid.


Can someone who is pregnant or breastfeeding use this medicine?

Anyone pregnant should speak to a medical professional before using.


How should Sudafed Decongestant Liquid be used?

For children aged 6-12, use one 5ml spoonful every 4-6 hours up to 4 times a day. For children over 12 and adults, use 10ml (2 5ml spoonfuls) every 4-6 hours up to 4 times a day. Do not use for more than 5 days without approval from a doctor.

  • Allergic reactions such as skin rashes
  • Hallucinations
  • An irregular heartbeat
  • High blood pressure
  • Restlessness and sleeping problems

Sudafed Decongestant Liquid – 100ml Reviews

Gary M,
My preferred sinus decongestant, I seem to get on with it better than the tablets. I also like that you can vary the dose with the 5ml/2.5ml spoon.
Easy to shop and delivered in a good condition.
I find this works better than the Sudafed pills. And is certainly easier to take than the massive tablets they are!! Very good product for those who are unable to take pills.
Good for kids when having a stuffy nose.
