I have had about 5 or 6 infusions and one of them caused a severe headache that lasted for several weeks. Another infusion caused a headache that was much less severe, but it still lasted for a few days. The timing suggests to me that the infusions caused the headaches, although my doctor and Centocor refused to accept that there was a connection.
My last few infusions have gone well.
