If you’ve tried to battle hay fever or year‑round allergies, you’ve probably wondered whether Xyzal is the right pick or if another antihistamine might suit you better. This article breaks down Xyzal (levocetirizine) side by side with the most common alternatives, so you can see the real differences in effectiveness, drowsiness, price, and more. By the end, you’ll know exactly which allergy pill fits your lifestyle.
Let’s dive into the details. Xyzal compare starts with understanding what levocetirizine actually is.
When it comes to seasonal allergies, Xyzal is a prescription antihistamine that contains levocetirizine, a third‑generation H1 blocker designed to reduce sneezing, itchy eyes, and runny nose with minimal drowsiness. It’s the active enantiomer of cetirizine, meaning it’s a more potent version that often works at lower doses. FDA‑approved for adults and children 6years and older, Xyzal is taken once daily, usually in the evening.
All antihistamines block the H1 receptors that histamine binds to during an allergic reaction. First‑generation drugs (like diphenhydramine) cross the blood‑brain barrier easily, causing sedation. Second‑ and third‑generation agents (loratadine, cetirizine, levocetirizine, fexofenadine, desloratadine) are engineered to stay out of the brain, reducing the sleepy side effect.
| Medication | Efficacy* | Onset | Duration | Drowsiness | Prescription? | Typical US$/Month |
|---|---|---|---|---|---|---|
| Xyzal | High | 30‑60min | 24h | Low | Yes | ~$30‑$45 |
| Claritin | Moderate‑High | 1‑2h | 24h | Very Low | No | ~$15‑$20 |
| Zyrtec | High | 30‑60min | 24h | Low‑Moderate | No | ~$12‑$18 |
| Allegra | Moderate‑High | 1‑2h | 24h | Very Low | No | ~$18‑$25 |
| Benadryl | High | 15‑30min | 4‑6h | High | No | ~$5‑$10 |
| Clarinex | High | 1‑2h | 24h | Very Low | Yes | ~$35‑$50 |
| Generic Levocetirizine | High | 30‑60min | 24h | Low | Yes (often OTC in some countries) | ~$10‑$15 |
Claritin is an over‑the‑counter, second‑generation antihistamine approved for ages 2years and up. It’s praised for virtually no sedation, but some users report it feels “weaker” during peak pollen spikes. Typical dose: 10mg once daily.
Zyrtec sits just a step behind Xyzal in the chemical family chain-cetirizine is the racemic mixture, while levocetirizine is the active enantiomer. That’s why Zyrtec can feel a tad more sedating for a subset of people, especially at night. It’s OTC, works fast, and is approved for kids 6months and older.
Allegra is unique because it doesn’t cross the blood‑brain barrier at all, making drowsiness practically nonexistent. However, it needs to be taken with water on an empty stomach; meals can cut its absorption by up to 50%. Dosage is 180mg once daily for adults.
Benadryl is a first‑generation antihistamine that many still keep in the medicine cabinet for acute allergy attacks or insomnia. Its rapid onset (15min) is a plus, but the heavy sedation limits daytime use. It’s OTC and cheap, but not ideal for everyday control.
Clarinex is a prescription‑only, third‑generation antihistamine similar to Loratadine but more potent. It’s a good fallback if Xyzal isn’t covered by your insurance. Drowsiness is rare, and it works for both adults and children 12months and older.
Generic levocetirizine offers the same active ingredient as Xyzal at a fraction of the price. In many countries it’s available OTC, though in the U.S. it remains prescription‑only. The efficacy, onset, and drowsiness profile mirror Xyzal exactly.
Xyzal is approved for children 6years and older. For younger kids, doctors usually recommend cetirizine (Zyrtec) or a pediatric formulation of loratadine (Claritin).
Because most second‑ and third‑generation antihistamines last 24hours, timing isn’t critical. Some people prefer nighttime dosing to avoid any mild drowsiness during the day, especially with Xyzal or Zyrtec.
Antihistamines treat the allergic inflammation that can trigger asthma symptoms, but they do not replace inhaled bronchodilators or steroid inhalers. Use them as an add‑on if you have allergic rhinitis that aggravates your asthma.
Benadryl is a first‑generation antihistamine that easily crosses the blood‑brain barrier, blocking central H1 receptors and causing sedation. It’s effective for short‑term use, but not ideal for daily allergy control.
Nasal saline rinses, local honey, and certain quercetin‑rich foods can help mild seasonal symptoms, but they don’t replace the potency of prescription antihistamines like Xyzal for moderate‑to‑severe allergies.
Start by reviewing your current allergy pattern. If you’re already on an OTC antihistamine and still sneezing, a trial of Xyzal or generic levocetirizine (with a doctor’s prescription) could be worthwhile. Keep the comparison table handy, discuss insurance coverage with your pharmacist, and monitor how you feel over a two‑week period. The right antihistamine can turn a miserable spring into a breathable one.

I’ve been on Claritin for a few seasons and found it works well for mild pollen. The low drowsiness makes it easy to take in the morning before work. If you need something a bit stronger, Xyzal is a solid step up without the heavy sedation of Benadryl. Just keep an eye on the price if insurance doesn’t cover it.
