Livial and Allegra are used in very different patients, and the points in common are limited. The main shared element is that both meet regulatory standards for efficacy and safety and benefit from pharmacist oversight.

Mechanism and action
Livial: Tibolone in Livial is rapidly converted to three active metabolites with tissue-selective activity. Allegra: Fexofenadine selectively blocks peripheral H1 histamine receptors, antagonising the effects of histamine on vasodilation, capillary permeability, sensory nerve endings and smooth muscle.

Frequently asked questions
Is Livial or Allegra better? ▾

Can I switch from Livial to Allegra? ▾
Switching between Livial and Allegra is rarely an appropriate decision since they belong to different classes and treat different conditions. The real question is usually whether the diagnosis calls for one medication or the other — which the prescriber resolves.
