I started Accutane (Claravis) 40mg on March 5th, and had to stop on March 30th, so I stayed on it just for 26 days. I had to stop because I had extreme dry eyes due to accutane. It was very uncomfortable, they were red, really dry, swollen,felt like I had sand or eye lashes in them. My eyes started to feel dry around the 10th day and escalated fast.
Stopping Accutane was a hard decision for me, as I am 33 years old and have tried everything and nothing worked, but I had to choose in between my eyes and my skin. I read about many people that got permanent dry eyes after Accutane. As far as I could read, most of the people that got permanent dry eye had bad dry eyes during the course of accutane and miserably managed to go till the end. As far as I know and what I talked to my doctor, it is normal to have dry eyes during Accutane but it can not be too bothersome, it has to be to the point the you need artificial tears just a few times a day and get relief from it, not every 30 minutes or more like me, and I actually felt like the tears didn't even work.
The minimum amount of Accutane you have to take is your body weight (in kg) times 120mg, and also you have to take it for more than 4 months because amount of time is important too. So, my example: 56kg x 120mg = 6,720mg. So in order to achieve that without such high doses, I set up a treatment plan with my doctor
40mg (first month), 50mg (three months) and 40mg (last month), total 5 months.
I could tell in 26 days that my eyes were bad enough that I could not keep going with it for more 4 months. So, if you are taking only 20mg and are already having problems you should consider that taking a low dosage you will have to stay on it for many months to achieve your minimum cumulative dose.
I know it is hard to stop Accutane as it was to me, specially because most of us have tried everything, but try to listen to your body signs, some people can handle Accutane, others cannot. Do not hesitate to see an eye doctor if you feel you should.
I am off Accutane for 7 days now and am using prescription drops (Zylet), making warm soaks on my eyes 2 at least 2 times a day and taking fish oil and still using artificial tears a few times a day but I am not feeling very well. My eye doctor told me I should start Restasis after and just stay on it indefinitely... so I still don't know if my eyes will be able to go back to normal, only time will tell me.
