Generally, fexofenadine (Allegra) is considered safe to use during fertility treatments and early pregnancy. However, because this itchy reaction is sudden and spread all over your body, it is incredibly important that you contact your fertility clinic or seek medical care right away before taking any medication. They need to evaluate the rash to ensure it is not a reaction to any medications used during your IUI. Please seek immediate emergency care if you experience any swelling of your face, lips, or difficulty breathing.
