Tamoxifen and kids

Did y’all hear about this? A Trenton, New Jersey CVS pharmacy accidentally dispensed tamoxifenn instead of pediatric fluoride pills.

Yikes.

I love CVS for the generous donations they made to Extreme Home Makeover, the feel-good show that used to be on TV. I searched to find a source to tell me how much CVS donated via the show over the years, but my patience wore off before I could find an answer. Suffice to say it’s a lot.

When I read about the drug mix-up, I cringed. The estimate is that as many as 50 kids received Tamoxifen instead of their chewable fluoride pills between December 2010 and February of this year. CVS hopes that any one of those 50 kids who tried to chew a tamoxifen pill instead of the usual fluoride pill would notice that something was different. Daniel Hussar, who teaches at the Philadelphia College of Pharmacy, was quoted as saying that because tamoxifen is meant to be swallowed, no effort is made to make it taste good, as is the case with chewable fluoride. He says a child who tried to chew tamoxifen would likely “want to spit it out or tell his parents it tastes bad.”

If they didn’t notice the taste, I wonder if they noticed the side effects. I pity the parent who has to deal with a moody, hot-flashing kid.

Because tamoxifen’s job is to block estrogen and prevent breast-cancer recurrences, it can monkey with one’s hormones. I’ve written about this very topic. More than once. I feel pretty qualified to complain about the side effects of tamoxifen, even though I know it’s an integral player in the recurrence-prevention game. I know well that this drug is my best shot for keeping that infernal cancer beast from showing its ugly mug around here again. The National Cancer Institute says explains it, “As adjuvant therapy (treatment given after the primary treatment to increase the chances of a cure), tamoxifen helps prevent the original breast cancer from returning and also helps prevent the development of new cancers in the other breast. As treatment for metastatic breast cancer, the drug slows or stops the growth of cancer cells that are present in the body.” Great right? Yes. Definitely. But, as we all know, there is no free lunch, and tamoxifen comes with some heavy side effects.

At the risk of sounding like one of those annoying commercials that lists every side effect under the sun, here goes:  increased chance of blood clots, increased risk of strokes, development of uterine cancer, and cataracts. But wait, there’s more: menopause-like symptoms such as mood swings, hot flashes, joint pain, and leg cramps. Not listed is the accelerated aging characterized by dry skin, loss of collagen, brown spots (aka “age spots”), and thinning hair. Because losing my rack isn’t enough, I also got thrown into chemically-induced menopause and became a brittle old woman decades before my time.

Not that I’m complaining.

Instead, I’m looking on the bright side: when I pop the little white pill every morning, I know exactly what I’m getting. No surprises. No mistaking a chewable fluoride pill for a powerful anti-cancer weapon.
