About Allegra

Buying Allegra online
Allegra is registered across 14 markets including Thailand, Malaysia and the Philippines, with availability also in Indonesia, Taiwan and South Korea. Generic fexofenadine, much of it produced in India, is far more affordable than the original brand. This helps expats and residents in areas where consistent supplies are hard to source. Allegra remains one of the most popular items ordered online for delivery across these territories.
