I have been taking plaquenil 200mg morning and evening for past 5 weeks for lichen planus polaris (scarring alopecia). I am told that this is the only cure to stop my hairloss. I awake every morning with a headache and stiff neck almost all day. My head is sore and also my eyes. My vision is blurred and I have trouble focusing. I am beginning to think there is a connection here to the plaquenil as it is the only medication I take apart from vitamins. Can you advise me.?
