Buy Sudafed Decongestant Liquid 

Sudafed Decongestant Liquid is a treatment for cold symptoms, including blocked noses or sinuses and catarrh.

 

How Sudafed Decongestant Liquid works

Sudafed Decongestant Liquid contains pseudoephedrine hydrochloride, a decongestant that relieves sinus and nasal congestion. 

Pseudoephedrine hydrochloride reduces the swelling of blood vessels in the nose, which helps to clear mucus and allows air to flow more freely into the cavities of your nose. 

 

Directions

Always take Sudafed Decongestant Liquid exactly as described in the patient information leaflet or as your doctor / Chemist4U pharmacist has told you. 

Shake the bottle thoroughly before use. 

Children aged between 6-12 years old: 1 x 5ml spoonful of Sudafed should be taken every 4-6 hours, up to 4 times a day.

Children over 12 years old and adults: 2 x 5ml spoonfuls of Sudafed should be taken every 4-6 hours, up to 4 times daily.
