Immunosuppressants for Atopic Dermatitis

I talked about treatments and what constitutes treatment. Now, as the wise Rafiki said, "it is time". Time to talk about immunosuppressants for Atopic, what they are and what they do, the dangers and complications, and (soon) the different types available to you.

Immunosuppressants are drugs that an expert dermatologist can prescribe for you. Their basic effect is, well, what their name says: they suppress your immune system. [As an aside, their main usage is "in organ transplant surgery to prevent organ rejection" (taken from Answers.com) and sometimes they are originally chemotherapeutic agents].

Don't try this "at home", i.e. without the benefit of an expert. Do not, I repeat, do not count on your physician to cut it. He or she may know you best but they do not know the effects of these drugs best. Let the experts do their job; dermatologists spent four or five extra years studying this, and they treat cases like you all the time. And definitely do not take them without medical advice at all! Don't even think about it.

Why could this be good for you? Basically, your immune system working over-hard, "panicking" and fighting things that aren't really dangerous to you (namely, allergens). This useless fight is causing you to itch, scratch, etc. Therefore, telling your system to "cool it" means it should stop fighting so hard. So it should cause an improvement in your situation. Several immunosuppressants have been consistently shown to cause improvement in many cases of atopic.

Why could this be bad for you? Well, immunosuppressants are heavy artillery. There are several effects, first and foremost - a higher sensitivity to contagious diseases. You should be careful not to come in too close contact with too many people, especially if you know they're sick. What's more, there can be interference with all sorts of normal bodily functions. During the time you're taking them, you should be under nearly constant "surveillance": complete blood count (CBC - the most basic blood test) and blood tests for liver and kidney functions, as well as blood pressure. The exact battery of tests you should undergo varies with the precise medication.

What else should you know?

Using immunosuppressants should clear up your atopic symptoms, including infections (via a complex mechanism that I don't entirely understand), but there is a possibility that you will be more vulnerable to skin infections, such as folliculitis, in which case you may need to add antibiotics as a backup player (or switch to a different immunosuppressant). Consult your doctor!

Note for the sexually active -

• females: for most of these drugs (if not all), you need to avoid pregnancy during the whole period of taking the medicine, and potentially for awhile after you stop. Plus, some of these drugs may reduce the efficiency of The Pill, so make sure you talk to your doctor about this, and add alternative contraception (condoms or otherwise).
• males: mostly there should be no problem, but double-check. At least one of these drugs (methotrexate) may cause birth defects in an unborn child if your partner gets pregnant. Best to be on the safe side and ask your doctor.
  

So, when should you take them?

First of all, it's important to note that it's not totally your decision to make. An expert doctor (usually a dermatologist) will decide whether or not your situation and specific condition merits this kind of treatment. Of course, you do have some choice here - you can (a) suggest it in case your doctor doesn't, or (b) refuse to take it if your doctor does suggest it.

But let's take a look at the criteria. An expert dermatologist may look at:

• How widespread your atopic is (are you erythrodermic?)
• How resistant your case is (did you respond to other treatment? topical cortisons? maybe UV?)
• How badly is atopic affecting your life (how much is it interfering with your day-to-day life?)
• How do your blood tests look before you start the drug (as mentioned earlier - are liver and kidney functions OK?)
  
• And potentially other things... see warning signs, and remember, I'm no doctor.

A separate post is coming up with the different types of drugs available to you.
