Thiotepa 100 mg powder for concentrate for solution for infusion

thiotepa

This medicine contains the active substance thiotepa, which belongs to a group of medicines called alkylating agents.

Thiotepa is used to prepare patients for bone marrow transplantation. It works by destroying bone marrow cells. This enables the transplantation of new bone marrow cells (haematopoietic progenitor cells), which in turn enable the body to produce healthy blood cells.

Thiotepa can be used in adults and children and adolescents.

Your doctor will calculate the dose according to your body surface or weight and your disease.

Like all medicines, this medicine can cause side effects, although not everybody gets them.

The most serious side effects of Thiotepa therapy or the transplant procedure may include:

• decrease in circulating blood cell counts (intended effect of the medicine to prepare you for your transplant infusion)
• infection
• liver disorders including blocking of a liver vein
• the graft attacks your body (graft versus host disease)
• respiratory complications

Your doctor will monitor your blood counts and liver enzymes regularly to detect and manage these events.
