Buy Sudafed Congestion & Headache Relief Day & Night 

Sudafed Congestion & Headache Relief Day & Night is the perfect way to fight your head cold. It provides targeted relief from a blocked nose, pressure and a heavy head. 

The congestion relief contains two different capsules - one for the daytime and one for the night.


How Sudafed Congestion & Headache Relief Day & Night works

The capsules are designed to provide you with relief, working both in the day and at night.

Both the capsules contain the active ingredients of phenylephrine and paracetamol. 

Phenylephrine is a decongestant which works by reducing the swelling in the nose. It also helps to clear your nasal passage so that you can breathe easier through your nose. 

Paracetamol is a painkiller. It works by reducing the pain you feel and your temperature. 

The daytime capsules also contain caffeine to help with your tiredness and boost pain relief. 



Always take Sudafed Congestion & Headache Relief Day & Night exactly as described in the patient information leaflet or as your doctor / Chemist4U pharmacist has told you. 

2 red/yellow capsules should be taken every 4-6 hours during the day. You can take the capsules up to 3 times per day. 

2 light blue/dark blue capsules should be taken at bedtime. 

Leave at least 4 hours between your daytime doses. Do not exceed the recommended dose.

Did exactly as expected. I have only used the day capsules so far when I experienced a strong headache at work (which I think was down to the heat and being dehydrated). Effects were noticeable within 45 minutes, and stopped the symptoms.
