Top 7 Allergy Relief Medicines That Actually Work

Most allergy advice online is a list of brand names with nothing to separate them. What follows is the shorter, more useful version: seven products we dispense constantly, what each is for, and where each one stops working. The two things worth checking on any allergy label are the active ingredient and its generation. A second-generation antihistamine — cetirizine, loratadine, fexofenadine — will not make most people drowsy. A first-generation one will, which is sometimes the point and is more often a surprise on a Tuesday morning.

When a spray beats a tablet

A tablet treats the whole body. A steroid nasal spray treats the nose, which is usually where the problem actually is, and it does so without the systemic effects. The trade is time: a spray takes several days of consistent use to reach full effect, so starting one the morning of a pollen spike is starting it too late.

The rebound trap

Decongestant nasal sprays — oxymetazoline, xylometazoline — work immediately and brilliantly, and stop working after about three days, at which point stopping them causes worse congestion than you started with. Three days is not a cautious guideline. It is the actual limit.

What to ask a pharmacist

Bring the list of everything else you take. Antihistamines interact with more than people expect, and the interaction that matters is rarely the one on the front of the box.
