Question: what is the difference between pepcid complete and pepcid ac?
Answer: Original Strength PEPCID AC® and Maximum Strength PEPCID AC® contain an H2 blocker that begins to work in 15 minutes and helps control acid all day or all night. * PEPCID Complete® combines an H2 Blocker with an antacid that starts neutralizing acid in seconds, so it works even faster.
