Antihistamines
Antihistamines are medications used to prevent or treat allergies. They work by blocking the release of histamine, a chemical in the body that causes allergy symptoms. Histamine is released when the body is exposed to an allergen, such as pollen, dust, or pet dander. Antihistamines can help relieve symptoms such as sneezing, itching, and watery eyes.
Fastest Working Antihistamines
The fastest working antihistamines are those that are taken orally, such as loratadine (Claritin) and fexofenadine (Allegra). These medications are usually taken once a day and start to work within an hour.
Another option is intranasal antihistamines, such as azelastine (Astelin) and olopatadine (Patanase). These medications are sprayed directly into the nose and start to work within 10 to 15 minutes.
Long-Acting Antihistamines
For long-term relief from allergies, long-acting antihistamines may be a better option. These medications work by blocking the action of histamine for a longer period of time. Examples of long-acting antihistamines include cetirizine (Zyrtec) and levocetirizine (Xyzal). These medications are usually taken once a day and provide relief for up to 24 hours.
Side Effects of Antihistamines
Antihistamines can cause a variety of side effects, including drowsiness, dry mouth, dizziness, and blurred vision. It's important to talk to your doctor about any potential side effects before taking any medication.
Conclusion
There are a variety of antihistamines available to treat allergies. The fastest working antihistamines are those that are taken orally, such as loratadine (Claritin) and fexofenadine (Allegra). Intranasal antihistamines, such as azelastine (Astelin) and olopatadine (Patanase), can provide relief within 10 to 15 minutes. For long-term relief, long-acting antihistamines, such as cetirizine (Zyrtec) and levocetirizine (Xyzal), may be a better option. It's important to talk to your doctor before taking any medication to avoid potential side effects.
