¿Puedo tomar antihistamínicos durante el embarazo?

Por qué sucede esto

Antihistamínicos cross the placenta, meaning they reach the baby's bloodstream. Some older 'sedating' antihistamines may cause irritability or tremors in newborns if taken close to birth. Additionally, some multi-symptom allergy tablets contain stimulants (decongestants) that can restrict blood flow to the placenta.

Lo que deberías hacer

Always speak to your GP, pharmacist, or midwife before taking any antihistamine while pregnant. Loratadine and cetirizine are usually the preferred 'non-drowsy' options if treatment is necessary. Avoid 'all-in-one' cold and flu remedies, as these often contain ingredients that are not safe during pregnancy.

Precauciones importantes

Pregnancy (Late Stage)

Taking sedating antihistamines close to the time of delivery can cause the newborn baby to experience irritability, tremors, or poor feeding. These should be avoided in the third trimester unless specifically prescribed.

Advertencias sobre alimentos y bebidas

Alcohol

It is best to avoid or strictly limit alcohol when taking antihistamines. Alcohol can significantly increase the sedative effects (drowsiness and dizziness) of these medicines, making you more likely to have an accident or fall. This is especially dangerous with older 'sedating' antihistamines, but can also happen with newer 'non-drowsy' types.

Fruit Juices (Grapefruit, Orange, Apple)

Do not drink grapefruit, orange, or apple juice while taking fexofenadine. These juices can significantly reduce the amount of medicine your body absorbs, making the treatment less effective. It is best to take fexofenadine with water.
