Medicine for low milk supply ??

My baby is 8 weeks old. I have been struggling with low breastmilk supply and have tried so many supplements, pumping every 3 hours nothing has worked. So today I went to a clinic and they prescribed me Raglan or gave me a choice of taking Domperidone. They did make me aware of side effects of these medicines. I really want to breastfeed my baby but not at the cost of my health. I took 2 doses of Reglan today but I’m kind of scared of the side effects. They also suggested me to take Goats Rue capsules and Moringa capsules to help with supply. Please advise.

(Supplements that didn’t work previously: Milkmaid lactation tea, munchkin lactation cookies, upspring lactation chocolate drink, GNC fenugreek capsules and Pure mom fenugreek capsules)
