How to take MacroBID
To take MacroBID, swallow 1 capsule twice a day after you’ve had some food or with a glass of milk. This will help you absorb MacroBID better and stop you from feeling sick. You should not crush or chew MacroBID capsules.
Your doctor will recommend if you need to take MacroBID for 3 days or longer, depending on your infection.
If you take more MacroBID than you should, go to a doctor or the nearest hospital. Take your pack of MacroBID with you.
