What is Rhinolast and How Does It Work?
Rhinolast is a brand name for a nasal spray containing the active ingredient azelastine hydrochloride. Azelastine is a potent second-generation antihistamine. It provides relief from allergy symptoms by blocking the action of histamine, a chemical your body releases during an allergic reaction. Histamine is responsible for common allergy symptoms like sneezing, itching, a runny nose, and watery eyes. By preventing histamine from binding to its receptors in the nasal passages, Rhinolast quickly alleviates these symptoms, often within 15-30 minutes. It is primarily used to treat the symptoms of allergic rhinitis (hay fever), which can be seasonal (e.g., pollen allergies) or perennial (e.g., dust or pet allergies).
Can You Buy Rhinolast Over-the-Counter (OTC)?
The answer to whether you can buy Rhinolast OTC is a firm no in many countries. In places like the United Kingdom and Australia, Rhinolast is classified as a prescription-only medicine (POM). This means you cannot purchase it off the shelf and require a prescription from a qualified healthcare provider.
However, the situation is different in the United States. In 2021, the FDA approved a nasal spray containing azelastine hydrochloride 0.15% for over-the-counter use under the brand name Astepro Allergy. While the brand name 'Rhinolast' itself is not sold OTC, its active ingredient is accessible without a prescription in the US. Generic azelastine and a lower 0.1% concentration still require a prescription in the US.
Global Availability and Different Brand Names
The active ingredient in Rhinolast, azelastine, is marketed globally under various names. While Rhinolast is a common brand in the UK and other regions, in the US, the most prominent brands are Astepro (for OTC and prescription) and Astelin (prescription). This is a crucial distinction for travelers or those moving between countries. What might be an easily accessible OTC product in one country could require a doctor's visit in another.

Proper Usage and Potential Side Effects
When using an azelastine nasal spray like Rhinolast or Astepro, it's important to follow the directions provided by a healthcare professional or the product packaging.
The most common side effect reported is an unpleasant or bitter taste in the mouth. Other potential side effects include:
- Drowsiness or fatigue
- Headache
- Nasal burning or irritation
- Sneezing
- Nosebleeds
Due to the potential for drowsiness, users should be cautious when driving or operating machinery until they know how the medication affects them. Combining it with alcohol or other central nervous system depressants should be avoided as it can increase sleepiness.
Conclusion
So, can you buy Rhinolast OTC? Not under that brand name in most places, as it is typically a prescription medication in countries like the UK. However, for those in the United States, the active ingredient azelastine is available over-the-counter as Astepro Allergy, offering a fast-acting and effective option for nasal allergy relief. For individuals outside the US, a consultation with a healthcare provider is necessary to obtain a prescription for azelastine-based nasal sprays like Rhinolast. Always check local regulations and consult with a pharmacist or doctor to determine the best course of treatment for your allergy symptoms.
