People’s Pharmacy: Poison ivy remedy helps ease chigger bite itch

My favorite remedy for chigger bites is Ivy-Dry. This product stops the maddening itch of the bites.

 

I live in an RV and can’t carry a lot of extra stuff with me. An RVer friend tried Ivy-Dry for chigger bites and decided he would rather use that than any of the preventives.

I apply the liquid version with a cotton swab. I’ve loaned my bottle of Ivy-Dry to fellow RVers, and it helps all types of itches.

Ivy-Dry contains benzyl alcohol, camphor and menthol. It is marketed as a way to treat the itching of poison ivy and poison oak, as well as for bug bites.

The skin contains nerve endings that are equipped with transient receptor potential channels. These respond to temperature and touch, as well as menthol and camphor. By stimulating these channels, you can overwhelm the nerves that are creating the itch sensation.

We still believe prevention is the best approach to chiggers and other biting bugs. Insect repellent with DEET or picaridin is effective. Some people report that dusting their shoes, socks and pants legs with powdered sulfur (flower of sulfur) keeps the chiggers and ticks away.

I was taking a lot of vitamin B-6 for my depression. After a while, my feet started feeling numb and cold. Now my legs and feet feel numb. Is there any way I can reverse this problem?

Too little or too much vitamin B-6 (pyridoxine) can cause nerve damage (Neuromuscular Disorders, February 2008). Symptoms of such neuropathy include numbness, balance problems and poor reflexes. You should see a neurologist and stop taking excessive doses of vitamin B-6 immediately.

I’ve been using Voltaren Gel and Flector patches for three years. (I call them “magic patches.”) Oral NSAIDs cause me major stomach pains, and the patches and gel do not.

I use the gel for arthritis pain in my knees, feet and hips. It works well enough that I can continue my demanding exercise schedule.

These meds don’t go through your liver, kidneys and other sensitive internal organs the same way oral meds do. So far, I’m not having any negative reactions.

Both Voltaren Gel and Flector patches are topical forms of the prescription anti-inflammatory medicine diclofenac. A thorough independent review concluded that topical diclofenac can provide good relief from osteoarthritis pain for some people (Cochrane Database of Systematic Reviews, Apr. 22, 2016).

Serious reactions appear to be uncommon. That might be because, as you suggest, the topical NSAID does not get into the bloodstream to the same degree as oral medications.

Some people do experience digestive upset from topical NSAIDs, however. One reader reported:

“I was prescribed Voltaren Gel for treatment of persistent groin pain related to a running injury. While it did offer some relief, it was no better than taking aspirin. However, I had serious gastrointestinal discomfort: gas, heartburn, painful swallowing. These side effects would clear up within a day or two after discontinuing use of the product.”

The Food and Drug Administration warns about both cardiovascular and GI complications from topical NSAIDs.
