Blurry vision after avonex?

[Hani_zf]

My first symptom was blurred vision and I used pulse corton and I cured completely
Today I had my first injection and After 9 hours my vision became just a little bit blurred again!
I am so worried about it
I heard some bodies had this condition too but it's rare.
Could it be a side effect of avonex?

Hi and welcome to the MS community,

To be honest i'm a little confused by your post, i think you may be slightly misinformed so with that thought in mind i will try to provide you with some information that you might find helpful in understanding MS.....

"My first symptom was blurred vision and I used pulse corton and I cured completely"

In relations to MS - Patients generally receive a  1-5 day course of intravenous treatment with steroids like Solu-Medrol, Decadron, methylprednisolone for acute MS attacks, because IV steroids basically help suppress the immune system which speeds the rate of recovery but high doses of IV steroids (pulse therapy) is not a 'cure' because it doesn't stop the disease that is attacking the central nervous system and causing the symptoms.

High dose IV steroids are often prescribed for various types of other medical conditions too, and with visual issues like Optic Neuritis (ON), which is the one of the most common visual issues associated with MS, the steroids do little to affect the resulting visual acuity because the inflammation and amount of deterioration of the optic nerve (also called the optic disk) is the only thing that determines the potential of full recovery or not, the more attacks the less likely that is...

You said "I heard some bodies had this condition too but it's rare." so i'm speculating on what you could be referring too; IF you are meaning MS presenting with 'bilateral' visual symptoms is rare, then yes technically 'bilateral' anything is rare with a neurological condition like MS, but visual symptoms are one of the more common symptoms of MS. Being diagnosed with optic neuritis for example is suppose to be one of the most common issues which lead to being diagnosed with MS, somewhere in the 90% plus range.

"Avonex' (interferon beta-1a) is one of the injectable disease modifying drugs for treating relapsing multiple sclerosis (RRMS), there are side affects like any other medication but blurred vision isn't one of the side effects i've heard of, and if one of your MS symptoms is blurred vision, it is more likely to do with your MS ie a pseudo relapse, which is a temporary return of prior symptoms with internal or external rise in temperature.

I hope that helps........JJ
