How long does it take to produce milk after using a lactation aid?

Patient's question:

No

Doctor's answer:

When using a lactation aid, it generally takes effect the next day with diet. It varies from person to person; some may see results within a few hours. Be cautious: if you use a lactation aid and do not promptly express the milk produced, your breasts may become extremely swollen, even leading to muscle spasms, causing unbearable, explosive-like pain.
