Are the 600 mg extended release as large as the 1200 mg?

I have used the 1200 and the 600 mg Mucinex. The 600 are the easiest for me to sallow. however, the 12 are longer lasting. When spring hits I need my Mucinex.

Is this unit easy to use?

It is a pill not a capsule. The Amazon description shows the pill size as one pictures. If you have no problem swallowing pills then it is easy to use.

Shows price as 1 cent. What's going on?

Thank you for your interest in Mucinex® SE. We recommend that you contact the Amazon seller directly so they can provide you with an answer to this question.

They sent me a product with only 3 months until expiration. No exchange allowed. What can i do now?
