    Sleep

    Upsides and benefits
    Claritin DNasonex
    • The antihistamine (Loratadine) in Claritin D (Loratadine / Pseudoephedrine) works as well as other antihistamines, but causes less drowsiness. It's also less sedating than Allegra D and Zyrtec D.
    • The decongestant (Pseudoephedrine) in Claritin D (Loratadine / Pseudoephedrine) is stronger than other decongestants. It can also help relieve congestion-related headaches and ear pressure.
    • The stimulant effects of Pseudoephedrine can give you some extra energy during the day.
    • Doesn't give you rebound congestion (worse congestion symptoms after you stop taking the medicine) like decongestant nose sprays can.
    • It's available without a prescription, unlike other strong allergy medicines.
    • First-choice medication for treating runny and stuffy noses caused by allergies. It works by reducing inflammation in the nose.
    • Because it's used directly where the inflammation is happening, it has fewer side effects than oral steroids do and has a lower chance of causing withdrawal symptoms once the medication is stopped.
    • Can be used as needed to help control symptoms in people age 13 years or older.
    • Available as a generic, which is cheaper.
    Downsides and risks
    Claritin DNasonex
    • You can have more side effects when using combination pills than when using single-ingredient medications.
    • The decongestant (Pseudoephedrine) can make your heart race or give you anxious or restless feelings.
    • You might not sleep as well due to Pseudoephedrine's effects and you can also have strange dreams while taking it.
    • Pseudoephedrine can raise your blood pressure, so don't take it if you have high blood pressure or other heart conditions.
    • Although you don't need a prescription, you do need to show a photo ID to buy this from behind the pharmacy counter.
    • Needs to be primed 10 times before it can be used, or re-primed if not used for more than 2 weeks.
    • Doesn't have a counter on it, so it can be hard to remember how many sprays are left (each bottle has 120 sprays).
    • Since the medicine in Nasonex (Mometasone) is a steroid, it can slow down your healing process if you've hurt your nose or had nose surgery.
