I've used Claritin or Claritin-D in the past to treat my allergies; I usually take it daily during allergy season, and for really congested days I take the Claritin-D. There's also a generic available (the generic name of the med is Loratadine) that's cheaper than the brand name. If you're concerned, though, you should really talk to your doctor and see what he/she recommends.
