Allegra after 60: doses and safety in older adults
Older adults metabolise medications differently, accumulate more comorbidities and take more concomitant drugs than younger users — all of which affect how Allegra (Fexofenadine) should be prescribed and used after age 60. The standard 30mg, 60mg, 120mg, 180mg starting strengths are usually adjusted, and the safety priorities shift.
Dose adjustments after 60
According to the prescribing information, most adults over 65 start Allegra at the lowest available strength of 30mg, 60mg, 120mg, 180mg and titrate up only with clear benefit and good tolerance. Reduced renal and hepatic function in older age slows clearance of Fexofenadine and prolongs effects. Caution is greater in the very old (>75).
Specific risks to consider
Falls, postural hypotension, confusion and interaction with cardiovascular medications are the main amplified risks for Allegra after 60. Fexofenadine selectively blocks peripheral H1 histamine receptors, antagonising the effects of histamine on vasodilation, capillary permeability, sensory nerve endings and smooth muscle. A standing blood pressure check after the first weeks of therapy is a simple, useful precaution.
