HOW TO USE: This product is used in combination with an acid blocker prescribed by your doctor. It's use is important because it helps the TCN/M/B work. Use the acid blocker exactly as directed. TCN/M/B comes as a package with 14 separate dosing cards. Each card is for one day (4 doses). There are 4 doses per day, hence 4 sections to each card. Each dose includes 4 pills: 2 round pink tablets to be chewed and swallowed, 1 white round tablet and one orange/white capsule to swallow. All 4 pills (1 dose) must be taken 4 times per day to work properly. REMEMBER: chew-chew- swallow-swallow is one dose.
