Let me explain how side effects must be repoted for medications.
When side effect profiles are complied for meds prior to FDA approval of a med, the manufacturers ask patients if they've experienced anything <b> bad </b> or adverse while on the med. Patiens are encouraged to report anything.
Patients who are on a medication like pneumonia typically have asthma, COPD, or CF. Therefore those patients are much more likely to get pneumonia than the average population.
But becuase manufacturers must include <b><u> all </u></b> all adverse events that occure while on the med, this shows up as a side effect. There is no way, says the FDA, to rule out if a side effect is or is not medication related.
I'll give you another example. Allegra 30mg has a side affect of accidental injury. Now, how many kids under the age of 10 bump into things and have accidental injsury? A ton. It's not necessarily medication related....
Here's a 3rd example. Let's say I had chronic migraines and I enrolled in a weight loss drug study. I was brought in by the manufacturer to record all adverse events, and they encourage me to record any discomfort/adverse events I've had in the past month. Well, I have chronic migraines, and I've suffered 2 in the past month, so I put it down on the survey. now that's included in the product's adverse events profile.
So while I'm not saying that all med's adverse events are bogus, because they 100% are not, take them with a grain of salt and understand how the data is collected.
