Beware XYZAL — allergy drug

I’m having a terrible allergy reaction that’s last 2 days. I visited my physician who gave me a few 5-mg samples of an allergy medicine, Xyzal (levocetirizine). This is supposed to be an alternative to Allegra, Zyrtec, and OTC Benadryl. I took time in the middle of the workday for this impromptu appointment so when I got back to work, I immediately took the drug. Then, I began feeling incredibly drowsy. I decided to look up the side effects on the xyzal site and found:

Patients taking XYZAL should avoid operating machinery or driving a motor vehicle. … Take XYZAL at bedtime. Do not increase the dose due to increased risk of sleepiness.

Great. I wish my doctor had warned me of this before I popped one at 3:45 in the afternoon at work, 13 miles away from my home. Not only that, but after doing some more reading in the Prescribing Information, I found:

Besides these events reported under treatment with XYZAL, other potentially severe adverse events have been reported from the post-marketing experience with cetirizine. Since levocetirizine is the principal pharmacologically active component of cetirizine, one should take into account the fact that the following adverse events could also potentially occur under treatment with XYZAL: hallucinations, suicidal ideation, orofacial dyskinesia, severe hypotension, cholestasis, glomerulonephritis, and still birth.

A one-time dose probably won’t affect me negatively in the ways reported above but still — it’s an allergy drug. ALLERGY drug. All this crap comes from something that’s supposed to make you feel better? Sheesh. Glad I read it. I’ll be sure to avoid regular consumption Xyzal in the future.

So now it’s 4:50 pm and I can barely keep my head up but I figured I’d make this quick post to warn anyone with mental illness who:

a) takes Xyzal or
b) thinks that allergy drugs are free from side effects triggering mental illness.

Granted, the risk is low but it exists. It also sounds like it can impair renal and hepatic functions somehow. Watch out if you’ve got kidney problems.

When work is over, I’m going straight home and making a beeline for my bed.

Word of the Day: Paroniria

Paroniria: Terrifying dreams causing sleep disturbances.

I was looking at the Allegra Web site to double-check whether my recent mixed-mood episodes might have been induced since I began taking the allergy drug regularly. (It’s not a far-fetched idea. Think Singulair.) "Sleep disturbances and paroniria" are a few of the many adverse effects listed for the drug.
