Understanding Antihistamines and Their Purpose

Antihistamines are medications primarily used to counteract the effects of histamines in allergic reactions. Histamines are substances your body releases during an allergic response, leading to symptoms like itching, swelling, and mucus production. Antihistamines work by blocking the action of histamines, effectively reducing or preventing these allergic symptoms.

• First-Generation Antihistamines (e.g., diphenhydramine, chlorpheniramine)
  • These tend to cause sedation and are often used for quick relief.
• Second-Generation Antihistamines (e.g., cetirizine, loratadine)
  • Less likely to cause drowsiness, suitable for long-term use.

Common Side Effects of Antihistamines

Most antihistamines come with a set of side effects that vary in intensity based on numerous factors including dosage, individual reaction, and the specific medication’s properties.

• Sedation and Drowsiness
  • Commonly experienced with first-generation antihistamines.
  • Second-generation options may also cause drowsiness but to a lesser extent.
• Dry Mouth and Eyes
  • Histamine blockade can decrease moisture production, leading to dryness.
• Dizziness and Unsteadiness
  • Particularly in older adults, which can increase the risk of falls.
• Urinary Retention and Constipation
  • Due to anticholinergic properties in some antihistamines.

Always consult a healthcare provider for a comprehensive list of side effects and personalized advice.
