It’s December 23rd and most people are likely spending the day baking Christmas goodies, purchasing that last minute gift, wrapping presents, picking up family at the airport, traveling, or engaged in some other holiday related activity. Not me as I’m sitting in the infusion clinic. I know the place and nurses very well since I come here for RA infusions. But today I’m not here to receive Rituxan which is my current RA biological medicine. I’m here because 11 out of the last 13 days have been spent dealing with chronic migraine headaches. Everyday there’s a low grade headache lingering all day long and then a migraine comes on rapidly usually in the early morning. I have to quickly take an abortive medicine like Imitrex and lay down in a quiet place to rest. But after two weeks of this, my neurologist wanted me to come into the clinic for an infusion of a cocktail of dihydroergotamine (DHE), phenergan (an antihistamine), and decadron (a corticosteroid) in order to put a stop to the migraine cycle. I had this same cocktail last year when taking Remicade and it works very well. I also started on a strong preventative medicine called topiramate (Topomax) about two weeks ago and that can take up to one month to begin working.
My neurologist believes that I already had a genetic propensity for migraines as I used to get them several times a year. But since dealing with RA, they seem to be rearing their ugly head more often and he believes that the combination of dealing with RA and the drugs I’m taking to combat the RA are contributing to the increase in migraines. I first noticed headaches when taking Humira years ago and then they came with a vengeance last year when taking Remicade. This lends some evidence that the RA medications may be a contributing factor in my case. Humira and Remicade are in the same class of RA drugs – TNF blockers – and both list headaches as a possible side effect. But I’m currently on Rituxan which is not a TNF blocker and acts on a completely different part of the biological process involved in RA. Methotrexate also lists headache as a possible side effect. I’ve temporarily stopped injecting methotrexate until we get these migraines under control. This experience makes me question long term RA treatment but that discussion will wait until later in January when I see my Rheumatologist. In the meantime, shaking the headaches is the short term goal.
