Dispose of mercury thermometer carefully

Q: The other day, I had a fever and was taking my temperature. When I was shaking my thermometer, the bottom broke off, and it spilled down the sink drain.

When I searched the Web for ideas about disposal, I got freaked out. What should I do about the mercury that went down the drain?

A: This is a serious situation, because liquid mercury from a thermometer can release mercury vapors that are toxic. They also can get into wastewater and cause dangerous pollution.

The mercury is probably caught in the U-shaped trap under the sink. A plumber could help you clean out the trap into a bucket. If you opt to do this yourself, though, be sure to wear disposable latex gloves. After removing the trap, empty the contents into a bucket. Carefully pour off as much water as you can and then use an eyedropper to pick up the mercury. Put it into a zip-top, sealable plastic bag. Seal the eyedropper in a separate bag and take both to a hazardous-waste collection site.

Your experience underscores the importance of eliminating all mercury-containing thermometers. Instead, consider a digital thermometer.

Q: My 88-year-old husband was prescribed Ambien for insomnia. After the first dose, he fell while getting up to go to the bathroom, gashed his head and had to go to the emergency room for stitches.

A: Your experience reminds us that sleeping pills may pose a serious risk for older people who have to get up at night to go to the bathroom.

Even over-the-counter sleep aids that contain the sedating antihistamine diphenhydramine (Advil PM, Nytol, Sominex, Tylenol PM, etc.) may contribute to unsteadiness and urinary retention. Other side effects may include reflux, next-day memory impairment, dry mouth and dizziness.

Q: I found that by applying solid antiperspirant to my bikini area following shaving, I have no bumps or irritation.

A: Bikini bumps are called pseudofolliculitis barbae and result from emerging hairs curling back under the skin instead of growing through it.

Washing carefully before shaving and using a product such as Hydroglide or Razor Rash Relief (www.mooreunique.com) helps soften hair for easier shaving and prevent post-shaving irritation. After shaving, 1 percent hydrocortisone cream also may reduce inflammation.
