1. What Hedex Extra does

Hedex Extra can provide extra relief from headache including migraine.

They can also relieve backache, rheumatic and muscle pain, toothache, sore throat, period pain, and relieve the fever, aches and pains of colds and flu.

The tablets contain two active ingredients. Paracetamol is a painkiller and also reduces your temperature when you have a fever. Caffeine acts to further help the effectiveness of paracetamol.

2. Check before you take Hedex Extra

Do not take Hedex Extra:

  • if you have ever had an allergic reaction to paracetamol, caffeine or to any of the other ingredients (listed in Section 6)
  • if you are taking other medicines containing paracetamol.

Ask your doctor before you take this medicine:

  • if you have liver or kidney disease, including alcoholic liver disease.

If you are taking other medicines

Talk to your doctor or pharmacist before taking these tablets if you are taking any prescribed medicines; particularly metoclopramide or domperidone (for nausea [feeling sick] or vomiting [being sick]) or colestyramine (to lower blood cholesterol). If you take blood thinning drugs (anticoagulants e.g. warfarin) and you need to take a pain reliever on a daily basis, talk to your doctor because of the risk of bleeding. But you can still take occasional doses of Hedex Extra at the same time as anticoagulants.

Pregnancy and breast feeding

If you take too many tablets

Immediate medical advice should be sought in the event of an overdose, even if you feel well, because of the risk of delayed, serious liver damage.

If your symptoms continue or your headache becomes persistent, see your doctor.
