Allergy Medications During Pregnancy.

Area of Science:

• Allergy and Immunology
• Obstetrics and Gynecology
• Pharmacology

Background:

• Allergic diseases frequently affect women of childbearing age.
• Pregnancy can alter the course of pre-existing atopic conditions, necessitating medication adjustments.
• Physicians must consider potential fetal risks when prescribing for pregnant patients with allergies.

Purpose of the Study:

• To provide guidance on managing allergic diseases in pregnant women.
• To identify safe and contraindicated medications during pregnancy for allergic conditions.
• To inform primary care physicians about medication choices for allergic conditions in pregnancy.

Main Methods:

• Review of current literature and clinical guidelines on managing allergic diseases in pregnancy.
• Evaluation of medication safety profiles concerning fetal development and congenital malformations.
• Categorization of medications into recommended, relatively safe, and contraindicated during pregnancy.

Main Results:

• Inhaled and intranasal corticosteroids (e.g., budesonide) are generally safe.
• Second-generation antihistamines (cetirizine, loratadine) and leukotriene receptor antagonists are considered safe.
• Certain medications, including first-generation antihistamines and specific immunosuppressants (e.g., methotrexate), should be avoided.

Conclusions:

• Careful medication selection is crucial for managing allergic diseases in pregnant women.
• Budesonide, cetirizine, loratadine, and leukotriene receptor antagonists are preferred options.
• Physicians must be aware of medications to avoid during pregnancy to prevent adverse fetal outcomes.
