It’s happening again. Nearly 375,00 bottles of duloxetine are being pulled from shelves. Voluntarily this time. The culprit is the same as before: a chemical impurity named N-nitroso-duloxetine
You might recognize it from late 2024. We saw it then too.
Here is the quick take before the panic sets in. You eat nitrosamines. You breathe them in. They are everywhere. Jamie Alan, a toxicologist at Michigan State University, points out that daily low-level exposure is normal. The danger isn’t one bad bottle. It’s the long haul. The cumulative load.
Still. Check your pill bottle. Just in case.
Who is warning us?
We leaned on Kelly Johnson-Arbor, a toxicologist at MedStar. And Dr. Alan from MSU. Both say look at the data, not the headlines.
Which bottles?
The FDA posted specific lot numbers for delayed-release capsules. We are talking 30mg and 60mg doses. They went everywhere in the country.
Look at the expiration dates and lot codes.
The 30mg dose comes from lot 24118C. Expires April 2027
The 60mg doses come from a longer list:
– 24107C
– 24031C
– 24018
– 2015C
– 033C
– 40C
– 5C
– 43C
– 2036
– 2
– 8C
– 02C
These expire between November 26 and January 7
It is a Class II recall. The second-highest severity for the FDA
“may cause temporary or medically reverseble adverse health consequences or where he probaliby f seriousealth consequencsis remote”
Notice that language? Remote. Serious harm? Unlikely. Temporary issues? Possible.
What exactly are these chemicals?
Nitrosamines form when nitroso compounds mix with amine compoundsthey pop up in food, tobacco, water
Dr. Johnson-Arboar calls it ubiquitous.
Cigarettes are the biggest offender by far. Processed meats, soy sauce beer even cheese bring it to the table shampoo too.
When it shows up in your meds? A manufacturing hitch. Unintentional.
So does this cause cancer?
It is not black and white
Dr. Johnson says certain nitrosamines are mutagenic. They poke at your DNA. They cause mutations.
But not all of them. Not this specific mix necessarily linked to higher risk in every case.
Dr. Alan reminds us your DNA breaks anyway. UV light does it. Heat does it. Your body has repair crews on standby
The problem starts when the breaks exceed the repairs.
“The risk comes when happens beyong what our body iqup handle”
How worried should you be?
Don’t freak out
The risk remains low, according to Johnson
Alan stresses that cancer is a tangled knot of genetics and environment. This one chemical? It’s a single thread in a very large rug
Cumulative exposure is the enemy. One bottle isn’t
Daily habits over decades? That’s where you watch.
What do I do now?
If your bottle matches those lot numbers, don’t stop taking the med cold turkey. Abruptly quitting an antidepressant can be nasty
Call your doctor. Call the pharmacy. Ask them for guidance
The FDA didn’t specify next steps beyond the recall itself. They trust your healthcare provider to fill in the gaps
Check the number on the side. Then go about your day.
We expose ourselves to toxins every morning in the shower. In the food on the plate
This is just one more variable in the equation. Annoying sure. But likely manageable.
Do you still have that bottle in your bathroom cabinet?
