Loratadine is a common antihistamine used for allergy relief. Pregnant individuals often have concerns about medication safety. Understanding available information about loratadine’s use during pregnancy is important for informed health decisions. This article aims to provide clarity on the topic, drawing upon scientific classifications and research findings.
Loratadine’s Pregnancy Safety Classification
Medication safety during pregnancy is assessed through classification systems that provide guidance. Under former FDA categories, loratadine was classified as Category B. This meant animal studies showed no fetal risk, but adequate human studies were lacking. The current Pregnancy and Lactation Labeling Rule (PLLR) offers more detailed information than simple letter categories. Loratadine is often a preferred second-generation antihistamine during pregnancy due to its non-drowsy nature and reassuring human and animal study data. While not formally categorized under the PLLR, available information generally supports its use when benefits outweigh potential risks.
Research on Pregnancy Outcomes
Research has investigated loratadine use during pregnancy, focusing on potential effects on fetal development. Studies generally conclude that taking loratadine is not expected to increase the chance of birth defects above the typical 3-5% background risk for any pregnancy. For instance, a study of 161 individuals taking loratadine in the first trimester showed no increased miscarriage risk. Early research once raised concerns about a link between loratadine use and hypospadias, a birth defect where the urethral opening is not at the penis tip. However, subsequent studies, including CDC analyses, did not find a consistent association, suggesting the initial link was likely due to chance. Most comprehensive reviews and meta-analyses have found no significantly increased risk of major birth defects, preterm birth, or low birth weight associated with loratadine use during pregnancy.
Alternative Allergy Management During Pregnancy
Managing allergies during pregnancy can involve various strategies, starting with non-medication approaches. Avoiding known allergens is a primary step, including keeping windows closed during high pollen counts or using indoor air purifiers. Simple measures like frequent hand washing, showering to remove pollen, and using dust mite-proof bedding also help reduce exposure. Saline nasal sprays and nasal irrigation (neti pot) are safe, effective ways to clear nasal passages and provide relief without systemic medication. When non-pharmacological methods are insufficient, other medications are considered generally safe. Nasal corticosteroids like budesonide, fluticasone, and mometasone are often recommended for moderate to severe symptoms. Cromolyn nasal spray is another option with a favorable safety profile, though it may take longer to show effects. Oral antihistamines like cetirizine are also considered safe alternatives to loratadine.
Seeking Medical Guidance
Given the unique nature of each pregnancy and individual health circumstances, consulting a healthcare professional is important before taking any medication, including over-the-counter options like loratadine. A doctor can evaluate personal medical history, pre-existing conditions, and allergy symptom severity to determine the most appropriate and safest course of action.

Discussing allergy symptoms and potential treatment options with an obstetrician or primary care provider ensures decisions are tailored to the pregnant individual and developing fetus.
