What do you recommend for rinnorrhea?

?cause: Rhinorrhea may be due to viral infection, cold or exercise, dust or allergies, medicines, smoke/pollution, just to name a few things. If it's a cold, you can try Robitussin but nothing will help much but time. For allergies or non-allergic rhinitis, otc drugs like zyrtec, claritin, (loratadine) Allegra are good and for stubborn cases, ask the pharmacist for a formulation with Pseudoephedrine (with a "d" label).
