Monday Pharmaceutical Mystery: April 27

Why was a patient prescribed something normally used for stomach problems to help her produce breastmilk?

A lady with a newborn baby comes into the pharmacy. She asks to speak to the pharmacist. You approach the counter, hands you a bottle of medication and says it’s not working.

She took this medication for 2 days and nothing happened. Then she looked up the medication on the internet and found out it is for stomach problems. She was expecting her doctor to give her something to help her produce breastmilk to feed her newborn baby.

You look at the bottle of medication, and it is for metoclopramide (Reglan) 10 mg tid. #90.

Mystery: Why did her doctor prescribe something that is normally used for stomach problems when she needs something to help her produce breastmilk for her newborn?

Solution: Metoclopramide is a galactagogue. It is used for initiating or augmenting maternal milk production. She has only been taking it for 2 days, and prolactin levels slowly go up with time. It is possible that her milk production will start after several more days, or possibly weeks of taking the drug.
