While there are no specific warnings against alcohol consumption with fexofenadine in the product labeling, it is generally advisable to avoid or limit alcohol intake while taking antihistamines. Alcohol can increase the risk of side effects such as drowsiness and dizziness, even though second-generation antihistamines like fexofenadine are less sedating than first-generation antihistamines.

Fexofenadine is not habit-forming and does not have the potential for abuse or dependence. It is used for its pharmacological action in blocking histamine and does not produce euphoria or any psychoactive effects.

Can this medicine be taken during pregnancy?

Fexofenadine is classified as FDA Pregnancy Category C, indicating that animal studies have shown an adverse effect on the fetus and there are no adequate and well-controlled studies in humans, but potential benefits may warrant use of the drug in pregnant women despite potential risks. Pregnant women should only use fexofenadine if clearly needed and after consulting with a healthcare provider.

Can this medicine be taken while breast-feeding?

Fexofenadine is excreted in breast milk in small amounts. While there are limited data on the effects of fexofenadine on a nursing infant, the drug is considered relatively safe for use during breastfeeding when used in standard doses. However, it is advisable for nursing mothers to consult with a healthcare provider before using fexofenadine to weigh the potential benefits and risks.
