Can Doxycycline Hyclate Harm a pregnancy?

Doxycycline hyclate is a tetracycline antibiotic that belongs to the *Tetracyclines* class.

Use during pregnancy or breastfeeding is not recommended because tetracycline antibiotics can cause permanent discoloration of the developing teeth (yellow-gray-brown in children under 8) and inhibition of bone growth in the developing fetus. Tetracyclines may also cause:

- hepatotoxicity

- fatty liver

- pancreatitis

- phototoxicity (sun sensitivity)

- pseudotumor cerebri (harmless bulging fontanel in infants)

Do not use tetracyclines during pregnancy or in children younger than 8 years of age.
