400 mg film-coated tablets

What Revalenk is and what it is used for

Revalenk belongs to the group of non-steroidal anti-inflammatory and anti-rheumatic drugs.

Revalenk is used to relieve the symptoms of mild to moderate osteoarthritis of the knee (joint wear and tear).

Glucosamine contained in Revalenk may also be approved for the treatment of other conditions not mentioned in this product information. Ask your doctor, pharmacist, or another healthcare professional if you have any further questions, and always follow their instructions.

What you need to know before using Revalenk

Do not take Revalenk if you:

  • is allergic to glucosamine or any of the other ingredients of this medicine (listed in section 6).
  • is allergic (hypersensitive) to shellfish, as glucosamine is extracted from shellfish.

Warnings and cautions

Revalenk should not be used to treat acute pain symptoms.

Talk to your doctor, pharmacist, or nurse before taking Revalenk if you have:

  • impaired glucose tolerance. Closer monitoring of your blood sugar level may be necessary at the beginning of treatment with Revalenk.
  • a known risk factor for cardiovascular disease, as an abnormally high level of cholesterol in the blood, has been observed in a few patients treated with glucosamine
  • asthma. When starting treatment with Revalenk, you should be aware that your symptoms may get worse.

Other medicines and Revalenk

Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines.

Caution should be exercised if Revalenk needs to be combined with other medicines, in particular:

  • certain types of medicines are used to prevent blood clots (eg warfarin, dicumarol, phenprocoumon, acenocoumarol, and fluindione). The effect of these drugs can be enhanced when used in conjunction with glucosamine. Patients treated with blood-thinning drugs will therefore be monitored extra closely when glucosamine therapy is started or stopped.
  • tetracycline ( antibacterial drugs used to treat infections ).

Please contact your doctor for medical advice.
