What are Sudafed Sinus Max Strength Capsules?

These Sudafed Capsules are a form of treatment that provides relief for the effects of sinusitis. Sinusitis is a condition that affects the nose and head primarily. Symptoms include a blocked, stuffy nose, a headache, a fever, and other aches and pains. These capsules work thanks to the three active ingredients that the capsules contain. These are:

  • Paracetamol
  • Phenylephrine
  • Caffeine

Paracetamol is the painkiller that reduces any aches and pains and can also reduce a fever. Phenylephrine is a decongestant that reduces the effects of a blocked nose and caffeine is a mild stimulant to treat fatigue and when added to paracetamol, can increase the painkilling effectiveness.


What causes sinusitis?

Sinusitis is usually caused by an infection and generally lasts for up to 3 weeks on its own. It is often around after a cold or the flu and is characterised by a number of different symptoms, including:

  • Pain and swelling around the cheeks, eyes, and forehead
  • A blocked nose
  • Green or yellow mucus coming out of the nose
  • A headache
  • A high temperature
  • A toothache
  • Bad breath

Using the right treatment can help to treat the condition and reduce its effects.


Who are these capsules suitable for?

These Sudafed capsules are suitable to be used by adults and children aged 16 and over.

Vanessa Ranaldi,
Have used before, great for the winter months
Placed my order, they took my money, then informed me that they could not supply both items together, so I said cancel the order, which they did, order cost £13.43 and they refunded me £12.94. Why I don't know as it was their fault not mine!
