Sadapron 100, 100 mg tablets

Sadapron 300 mg tablets



Sadapron tablets contain a medicine called allopurinol. It works by slowing down the speed of certain chemical reactions in your body.

Sadapron is used:

  • to prevent gout. This is a disease where your body produces too much of a substance called ‘uric acid’. The uric acid builds up in your joints and tendons as crystals. These crystals cause an inflammatory reaction. The inflammation causes the skin around certain joints to become swollen, tender and sore when only slightly touched. You can also find you get severe pain when the joint is moved.
  • to prevent other conditions where there is a build up of uric acid in the body. These include kidney stones and certain other types of kidney problem and when you are having treatment for cancer.



Do not take Sadapron

  • if you are allergic (hypersensitive) to allopurinol or any of the other ingredients of Sadapron tablets (listed in section 6).

Do not take Sadapron if the above applies to you. If you are not sure, talk to your doctor or pharmacist before taking Sadapron.

Serious skin rashes which include hypersensitivity syndrome, Stevens- Johnson syndrome and toxic epidermal necrolysis, have been reported with the use of allopurinol. Frequently, the rash can involve ulcers of the mouth, throat, nose, genitals and conjunctivitis (red and swollen eyes). These serious skin rashes are often preceded by influenza-like symptoms, fever, headache, body ache (flu-like symptoms). The rash may progress to widespread blistering and peeling of the skin.
