This medication can be used to treat or prevent low levels of iron in cases when it can not be achieved through your diet or if you have experienced a large amount of blood loss.

How does it work?

Ferrous Sulfate can begin to show signs of improvement after one week. It helps the body to replace red blood cells which carry oxygen around the body.
