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.


Are there any side effects?

Like with many medicines, there is a chance of side effects. Potential side effects include:

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

If you notice any side effect, stop using and speak to a doctor or Chemist 4 U pharmacist as soon as possible. Any side effect that you notice can be recorded by using the MHRA Yellow Card Scheme.


Why do I need to answer questions to buy this product?

You do not need a prescription for Sudafed Decongestant Liquid, however, you will be asked to complete a short medical questionnaire by your Chemist 4 U pharmacist before we can take your order. This includes some simple questions that all pharmacies legally are required to ask before supplying this kind of product. This helps our pharmacy team to be sure that Sudafed is the best choice for you.

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.
