Headaches on imuran

Hey guys, just wondering if any of you on imuran get brutal headaches, almost like migraines, iv been on it now for a few months, nausea is gone but I am getting severe headaches every now and then, almost fortnightly, they're bad too the point that I'm gonna ask the doc for a MRI to make sure my head is okay, could It be the imuran? Unlikely it'd be the pentasa?

Hi, I m not on Aza but was on them last year for a short while. Aza gave me pancreatitis :-((
I do suffer with Crohs and time to time do get massive headaches. Consultant says i get headaches due to body in stress because of Crohs.. It comes and goes and nothing can stop the pain :-))
I have learned to live with it..
Hope yours is not so bad!!

I have been on Imuran for a while and I never got side affects until recently. I too get bad headaches, Ive had this one nearly all day, I think it must be the pills.

Hi I've been on Aza nearly three years and have found headaches were a problem for some of that time, speaking to pharmacist I think a lot of it comes from upper back/ neck tension as I find that muscles are very sore a lot of the time. This is apparently not uncommon on this drug as it's stored in the muscle ... I've tried regular massage / heat packs to stop the neck shoulder pain from becoming constant headaches. Otherwise I've found it fairly painless to be on and have had remission until recently so it's been worth it.

Headaches are quite a common side effect of Imuran/Azathioprine. When I was on it and had first got up to my therapeutic dose of 125mg, I was taking the dose with my evening meal as I was on Pred, Mesren and antibiotics as well and trying to space the pills out during the day. I found I was waking up around 3 in the morning every day with an awful headache around the back of my head and neck.
Friends on the forum advised me to split the dose so I started taking half in the morning and half in the evening and that did the trick.
Other things that help are drinking plenty of water and taking your tablets with food.

Yep, headaches for me on Imuran. About one a week. It is so bad at times that I can not lay horizontal but have to sleep sitting up. I'm taking 150mg=200mg. But also, check your blood pressure. Mine reached 187/102. I had to stop for a couple of days. Yes, drink alot of water throughout the day - keep your liver workin.
