Mucinex Works Great

works great

[This review was collected as part of a promotion.] it works great to break up congestion, especially during allergy season! formulation means it'll last for 12 hours… & it does. the size of the pill makes it a bit hard to swallow

Fast acting relief

[This review was collected as part of a promotion.] The packaging explains exactly what it's used for, pill is not extremely large which is perfect as I have a hard time with large pills and has long lasting relief
