Infrequently, iron dextran for injection has caused severe (sometimes fatal) allergic reactions. It should be used only when clearly needed and when a patient is unable to take iron by mouth (oral forms).Who should not take Imferon injection?
This medication is used to treat "iron-poor" blood (anemia) in people who cannot take iron by mouth because of side effects or because their anemia has not been successfully treated by it. Low iron levels can occur when the body can't get enough iron from food (poor nutrition, poor absorption) or when there is a large or long-term blood loss (e.g., hemophilia, stomach bleeding). It is also used by people who have anemia due to long-term kidney disease.
Iron is an important part of your red blood cells and is needed to carry oxygen in the body.
This medication is usually injected deep into the muscle of the buttock or slowly into a vein as directed by your doctor. When injecting into the buttock, the next injection is given on the opposite side from the last injection.
Before the first full dose, a smaller test dose is given slowly to check for possible allergic effects. If no reaction is seen after one hour, the full dose may be given. You will be checked carefully for reactions by a health care worker each time you are getting the iron.
Iron injections may be given once daily in small doses or as directed by your doctor. Large doses may be given in a solution and injected into a vein over several hours. Some side effects such as dizziness and flushing may be stopped by giving the drug more slowly. The dose and length of treatment is based on your age, weight, condition, and response to therapy. Your doctor will order blood tests to monitor your response.

Some people may experience a delayed reaction 1-2 days after their treatment. These side effects usually lessen within 3 to 4 days if the medication was injected into a vein or within 3 to 7 days if the medication was injected into a muscle. Tell your doctor if any of these side effects persist or worsen more than 4 to 7 days after your treatment: back/joint/muscle aches, chills, moderate to high fever, headache, nausea/vomiting.
