  • if you are allergic to any of the ingredients of this medicine (listed in section 6)
  • if you have a history of sensitivity to vitamins B and/or C.

Warnings and precautions

Talk to your doctor before taking Pabrinex IVHP.

Pabrinex IVHP should be given with extreme caution if you have:

  • ever had a mild allergic reaction (sneezing or mild asthma) to any previous injections of vitamin B1 (thiamine). This could mean that you may have become hypersensitive, and could have a more severe allergic reaction if given Pabrinex IVHP.

Other medicines and Pabrinex IVHP

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

  • Levodopa (used in the treatment of Parkinson’s disease) – Pabrinex IVHP interferes with the effects of this medicine.
  • Vitamin B1 (thiamine) injections - if you are on repeated injections of such preparations, Pabrinex IVHP may cause sneezing or mild asthma (chest tightness and wheezing) or even anaphylactic shock if you have become hypersensitive.
