Our pharmacists’ bottom line
Clarinex (Desloratadine) is a good option for once-daily allergy relief. It doesn't make you feel sleepy, but you need a prescription.
- Relieves allergy symptoms like sneezing, runny nose, congestion, hives, or itchy skin.
- Preferred for older people since it causes little to no drowsiness compared to other antihistamines like Diphenhydramine (Benadryl).
- Works faster than other non-drowsy antihistamines like Loratadine (Claritin).
- Side effects are rare and usually mild.
- Available as a liquid or fast-dissolving tablet for people who don't like swallowing pills.
- May not work as fast as the other antihistamines that make you sleepy (like Benadryl).
- Not a good medication for pregnant women to take.
