What do doctors think is the top OTC med for me to buy to help my severe sinus and allergy condition?

Several choices. Available otc medications for allergy that are effective without drowsy side effects are claritin, (loratadine) zyrtec and allegra. For the person with sinus congestion, each of these has a preparation combined with the decongestant Pseudoephedrine (sudafed). These combination products are: Claritin (loratadine) d, zyrtec d and Allegra d. If symptoms are not controlled, an allergist can assist in more effective therapy.
