What's worse than allergies? Allergy medication gone wrong. If your trail trek begins at the local pharmacy, the University of the Science in Philadelphia warns that over-the-counter allergy medications can do more harm than good when mixed with other meds. Incompatible allergy products can lead to stomach, kidney or liver problems over time.

Dr. Daniel A. Hussar, a professor at the university, says not to let advertising sway you. A large number of ingredients might sound like a cure-all, but isn't necessarily a good thing. "Consumers should read the warnings on over-the-counter medicines and consult with the pharmacist in order to make educated decisions about with allergy medication is right for them."

Start by working with your pharmacist to find an allergy medication that will:

• Leave you alert. If you're mountain biking, spelunking or using gear of any form, you can't afford to be drowsy.
• Not interfere with your current medications (prescription or non-prescription)
• Treat only the symptoms you have.

Once you find a medication, follow the instructions. Over medicating, even with the appropriate product, can misfire. For example, prolonged use of short-term nasal spray decongestants can cause a rebound effect. "When the dose wears off, the congestion comes back, and it comes back sooner after each dose," Hussar says.

Fortunately, the rights meds, taken properly, can get you out of the house and back on the trails as nature intended.
