Although you may need antibiotics to clear up an infection, nothing stops the drips better than chlorpheniramine maleate. That is the generic name. It is a common ingrediant in many OTC cold remedies but it’s better to just get the generic and take it according to directions about 4 mg every 4-6 hours. It is also very economcal, usually less than 5 bucks for 100.
If you are stopped up pseudoephedrine (generic sudafed) is best. If you are both stopped up and running it is OK to take both of them at the same time. Just avoid taking more than one combination drug at a time because most of them contain the same 4 or 5 ingrediants. Also be aware that pseudoephedrine can make you jittery—like caffiene so take with caution at bedtime.
Oh and increase your fluid intake. It will thin the secretions and make them easier to eliminate. Saline nasal spray used liberally will also help clean out the passages.
Take it easy if you can.
