Allegra typically starts working within about 1 to 2 hours for most allergy symptoms, and many people notice relief within that window. It can vary a bit by individual and by the specific symptoms you’re treating. Key points:
- Onset: about 1–2 hours after taking a dose for sneezing, runny nose, and itchy eyes.
- Duration: the standard 12-hour or 24-hour formulations can provide lasting relief (check your exact product). If you have kidney problems, a healthcare provider may adjust dosing.
- What to expect: Allegra is a non-drowsy antihistamine, though individual responses can vary; if you don’t notice improvement after a couple of days, or if symptoms worsen, consult a clinician.
If you’d like, I can tailor guidance based on your specific form (12-hour vs 24-hour tablet), your age, and any other medications you’re taking.
