Chlorpheniramine and Phenylephrine
The decongestant phenylephrine is often combined with chlorpheniramine. The combination works well when sinus pressure accompanies allergy symptoms
Some of the brand names of this combination include: Actifed® Cold and Allergy, and Sudafed® PE Sinus and Allergy
Although drowsiness is common with the first generation antihistamines, chlorpheniramine 4mg seems to be tolerated well. I have seen many people get relief from their allergies and still remain alert.
Also, sinus rinse kits can remove irritating pollen from the sinus cavities. Try the NeilMed Sinus Rinse Kit you may be amazed how well it works.
