Can treosulfan cause problems?
Retour au sommaireMedicines used to treat cancer can have a number of side-effects, some of which can be delayed for several days or weeks after taking the medicine. Most chemotherapy medicines can lower the number of white cells in your blood, which increases the risk of you getting an infection. While you are taking treosulfan you should take precautions to reduce the risk of getting an infection - you can do this by avoiding being with people who you know have an infection. If you think you are getting a sore throat or if you have a high temperature, please let your doctor know as soon as possible so that you can get some treatment straightaway.
Your doctor will discuss with you the possibility of unwanted side-effects from your treatment, although not everyone experiences these. The table below contains some of the side-effects associated with treosulfan. You will find a full list in the manufacturer's information leaflet supplied with your medicine. Please let your doctor know if you experience any of the following:
Very common treosulfan side-effects (these affect more than 1 in 10 women) | Que puis-je faire si je ressens cela ? |
Une température élevée (fièvre), ou des symptômes d'une infection | Informez votre médecin de cela immédiatement |
Se sentir malade (nausée) ou être malade (vomissements) | Stick to simple meals - avoid rich or spicy food. If this becomes troublesome, let your doctor know, as you can be prescribed an anti-sickness medicine |
Some loss of hair; a bronze skin colouration | Discuss these with your doctor if you are concerned |
Rare treosulfan side-effects | Que puis-je faire si je ressens cela ? |
A burning feeling as you pass urine, blood in your urine | Continue to drink plenty of water and try to pass urine frequently. If you notice blood in your urine, please let your doctor know straightaway |
