I contracted poison ivy three days ago. I've had it often enough to know that, once I identify the rash, I have at least four weeks of topical creams, oatmeal baths, and weeping blisters to look forward to. As I'm breastfeeding, I wanted something that wouldn't affect my baby. As I also have the flu, I have little tolerance for other discomfort. So, Zanfel claims safety for nursing moms and relief from itching in 15 seconds to three minutes. I figured it was worth a shot, even if it cost a lot.
In a nutshell:
Pros: decreased itching and oozing; it does what the big print on the box says it should
Cons: cost; didn't stop the rash from spreading; smoke and mirrors marketing and "research"; basically an exfoliating soap; as effective as a placebo, according to Zanfel's website
More specifics
Here's what I like about the product:
1. The itching stopped after about a minute and didn't return for another ten hours (when I rubbed the rash in my sleep).
2. The area that I cleaned with the Zanfel is already improving in looks. I have a line of blisters on my forearm about an inch long that I would classify as a "moderate" rash. The blisters are subsiding and the "weepiness" has decreased quite a bit. The rash is still spreading, but more slowly than normal.
3. Impressive Marketing--This product is on the shelves of major chains with no legitimate data supporting its efficacy or safety, and suckers like me are shelling out big bucks for what appears to be an exfoliating cleanser.
Here's what I don't like:
1. Cost, of course.
2. Zanfel did not stop the rash from spreading.
3. Ingredients are listed, but there is no specific information about active vs. inactive ingredients, ingredient concentration, FDA approval, etc. on the packaging or the Zanfel website. Although I get tired of overregulation, I've grown accustomed to knowing that the medications I use have been studied in clinical trials.
4. Safety/sensitivity concerns--Although the product makes claims of safety more readily than any other medication/ointment I've ever used (safe for the face, eyelid, genitals; okay for nursing moms), a couple of ingredients may cause an allergic reaction in people with "sensitive skin." (This warning is not on their packaging or their website; it's found elsewhere in pharmacology data for cosmetics, drugs, etc.) If you have poison ivy, I'm betting your skin is already sensitive, especially in the area you'll be scrubbing with the product. So, beware, even if they tell you you don't need to worry.
5. Bizarre directions--Directions for applying the product to the forearm (where my rash currently resides) suggest using "a soft rubber spatula or similar device that won't puncture the skin." First of all, I'm not a big fan of using kitchen utensils for body grooming and cleansing, especially where there are weeping wounds. (I had a hard enough time convincing my daughter that a fork is not a hairbrush.)Second of all, there is no need to use anything other than your hand to scrub your wound. If you scrub too hard, you create new lesions and open yourself up to other infections.
6. Lack of data--no legitimate, independent studies that I could find have proven the efficacy of Zanfel. Two studies are cited on their website. One sounds reasonable enough (although why anyone would volunteer to have the toxic urushiol oil rubbed on their skin is beyond me and seems like it would require some kind of oversight) and showed a decrease in the discomfort level and the size of the rash after a few hours. The other study, by the Zanfel website's own account, "demonstrated that an objective score combining erythema, induration, and vesiculation was reduced ... in patients who washed with the soap or placebo." Hmmm, if even the placebo improved the patient's state, maybe I paid too much....
Additionally, the pyramid graph that's displayed on the Q&A page included in the product box has nothing to do with Zanfel, but it's pretty.
7. Shaky or irrelevant "expert" testimony--The dermatologist quoted on the Q&A page makes no mention of Zanfel, but I guess they thought his name in their literature gave them credibility.
Many of the experts who testify to the efficacy of Zanfel on the website are pharmacists, nurses, and doctors, and their names and contact information are included. Of course, most of them are not experts in dermatology. One is an Ob-Gyn, one is an optometrist, and one is a veterinarian. Other experts cited include a teacher and a judge. Not exactly convincing evidence, in my "expert" opinion.
