What is loratadine used for?

Loratadine temporarily relieves symptoms of seasonal allergies (hay fever) and other upper-respiratory allergies, including sneezing, runny nose, itching of the nose or throat, and itchy, red, watery eyes. It also relieves itching due to chronic hives (chronic idiopathic urticaria) when the cause of the hives is not known. If you know what is triggering your hives, do not use loratadine for it - see your doctor, because it will not prevent hives from a known cause.

Is loratadine the same as Claritin?

Yes. Loratadine is the generic name for the active ingredient in Claritin, and it is also sold as Alavert, Claritin RediTabs, and Children's Claritin. The generic and brand-name products contain the same medicine; the generic is typically less expensive.

Does loratadine make you sleepy?

Loratadine is a non-sedating antihistamine and usually does not cause significant drowsiness at the recommended dose. However, some people do experience drowsiness or fatigue, and this is more likely if you take more than the maximum recommended dose.

Can you take loratadine every day?

The usual over-the-counter dose is 10 mg once daily, and many people take it daily during allergy season. If you have liver or kidney disease, ask a doctor first, because a reduced schedule such as every other day may be recommended. Check with your doctor or pharmacist about ongoing daily use.

Looking for a loratadine coupon? Loratadine is a second-generation, non-sedating antihistamine sold over the counter and also stocked at the pharmacy counter. It is the active ingredient in Claritin, Alavert, and Children's Claritin, and it relieves seasonal allergy symptoms like sneezing, runny nose, and itchy, watery eyes. Even though it is available without a prescription, an Rx.com coupon can sometimes lower the pharmacy cash price on the generic or combination products. Enter your ZIP above to see today's price at pharmacies near you.

What is loratadine and how does it work?

Loratadine is a second-generation (non-sedating) antihistamine that works by blocking peripheral H1 receptors, the sites your body uses to trigger allergy symptoms. By quieting this response, it temporarily relieves symptoms of seasonal allergies (hay fever) and other upper-respiratory allergies, including sneezing, runny nose, itching of the nose or throat, and itchy, red, watery eyes. It also relieves itching due to chronic hives (chronic idiopathic urticaria) when the cause of the hives is not known. If you know what is causing your hives, do not use loratadine to treat it - see your doctor instead, because the product does not prevent hives from a known trigger such as a food, medicine, or insect sting.

The standard over-the-counter dose is 10 mg once daily. Loratadine is also combined with the decongestant pseudoephedrine as Claritin-D (loratadine-pseudoephedrine) for people who also have nasal congestion. This information is educational and is not a substitute for advice from your doctor or pharmacist.

How to save on loratadine with an Rx.com coupon

Loratadine is available over the counter, so you can buy it without a prescription. That said, cash prices vary widely from pharmacy to pharmacy, and some over-the-counter items can be cheaper with a coupon or when your provider writes a prescription for the pharmacy-counter version. An Rx.com coupon is free to use and may help on the generic tablets or on combination products like Claritin-D.

To check what you would pay, enter your ZIP above to see today's price at pharmacies near you, then bring the coupon to the counter. Because loratadine has a generic available, comparing the store-brand generic against the brand name is often the simplest way to save.

Loratadine vs. other allergy antihistamines

Loratadine is one of several non-drowsy, once-daily antihistamines. If it does not fully control your symptoms, your pharmacist may suggest trying a different one, since people respond differently to each:

  • Claritin - the brand-name version of loratadine.
  • Cetirizine (Zyrtec) - another second-generation antihistamine.
  • Fexofenadine (Allegra) - a non-sedating option.
  • Desloratadine - a close chemical relative of loratadine.
  • Levocetirizine - a once-daily antihistamine related to cetirizine.
  • Loratadine-pseudoephedrine (Claritin-D) - adds a decongestant for congestion.

There is no single best choice for everyone. If one antihistamine does not work well or causes side effects, ask your doctor or pharmacist about switching.

Safety and side effects

Loratadine has no boxed warning and is generally very well tolerated and non-sedating at recommended doses. Some drowsiness can still occur, especially if you take more than the maximum dose. The most common side effects are headache, drowsiness, fatigue, and dry mouth; in children, nervousness and abdominal pain have also been reported. If you have liver or kidney disease, ask a doctor before use - a reduced dosing frequency (every other day) may be recommended. Do not use loratadine if you are allergic to loratadine or desloratadine, and talk to your doctor before using it during pregnancy or breastfeeding.

Rare but serious reactions include a severe allergic reaction (rash, hives, facial swelling, or trouble breathing), a fast or irregular heartbeat, seizures, and fainting. Seek medical care right away if any of these occur. This is general information, not medical advice - check with your provider or pharmacist about what is right for you.
