What are Sudafed Congestion & Headache Day & Night Capsules?

Sudafed Congestion & Headache Day & Night Capsules are an all-day treatment that works to relieve the effects of nasal congestion and a headache. This treatment contains two types of the capsule that help to relieve drowsiness during the day but also help to get a good night’s sleep with the night capsules. The night capsules contain two active ingredients that provide relief, which are:

  • Paracetamol
  • Phenylephrine

Paracetamol is a painkiller that helps to reduce aches and pains, and can also reduce a fever. Phenylephrine is a decongestant that helps to unblock the nose and help you to breathe easier. The day capsules contain both of those ingredients but also another active ingredient, caffeine. Caffeine is a mild stimulant that helps to reduce drowsiness. Caffeine and paracetamol combined can increase the effectiveness of the painkiller.

Anneka Moore,
Very affective and handy would recommend
Sue ,
I was very pleased with this product it is very fast acting capsules.I started to feel relief within the hour and it just got better so that within a day my congestion was virtually gone. Highly recommend.
Julian ,
Great quick working product
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.
