Can I Take Leptaden Along With Galact To Improve Breast Milk Supply?

Hi, I ha c section and my milk supply was low until 6 weeks. Doctor suggested Domperidone and it helped to some extent. but I had lot of side effects had to discontinue that . I have started on galact from 5-6 days but no improvement in fact it has reduced a little bit. I do mixed feedings direct feeding and expressing as my little one does not drink properly at times ( she does not like to latch on left side when she is awake) . Can I take leptaden tablet to improve the milk supply along with Galact or should I discontinue Galact while taking leptaden , Thanks
