The medication a doctor prescribes to treat anemia depends on the type of anemia a person has. For example, a person can take supplements to treat nutrient-deficiency anemia. More severe or chronic types of anemia will require different medications.
Iron deficiency anemia is the
This article looks at the goals of medication for anemia, which medications a person may require, how to take them, and how the medication works.
It also looks at the benefits and potential side effects of medication for anemia.
Medication treatment goals for anemia will differ depending on the type of anemia a person has and the underlying condition that is causing it.
For someone with mild anemia related to a nutrient-deficient diet or a temporary circumstance such as pregnancy, the goal may be to replenish lost nutrients and vitamins with supplements and other medication in the short term.
For others who experience chronic or severe anemia, the goals of medication can
- increasing the hemoglobin level or red blood cell count to improve the blood’s ability to transport oxygen
- relieving symptoms of anemia and improving a person’s quality of life
- reducing the risks of complications of anemia, such as nerve or organ damage
- treating an underlying condition that may be the cause of the anemia
A person with iron deficiency anemia does not have enough iron in their body to produce a protein called hemoglobin.
This protein enables red blood cells to transport oxygen throughout the body, which is essential for the proper functioning of the organs.
A person can
- ferrous sulfate
- ferric sulfate
- ferrous gluconate
- ferric citrate
A doctor may recommend a specific dosage.
In cases where anemia is not chronic, a person may require several supplements a day for
Individuals should take iron supplements exactly as the doctor directs, as too much iron may cause harmful side effects.
Iron supplements can help replenish the body’s iron levels, which can relieve symptoms of anemia
- gastrointestinal problems
- problems with memory and concentration
If a person does not receive treatment for anemia, they may be
There are various potential side effects of iron supplements, especially if a person takes high doses. These include:
In extremely high doses, iron becomes toxic and may cause severe side effects,
Iron may also interact with other medications and supplements. A person should disclose any other medication they are taking with their doctor, including natural or herbal supplements.
To help mitigate the side effects associated with iron, a person may need to take a delayed or enteric-coated formulation.
If iron supplements are not adequate to replenish a person’s iron levels, they may require intravenous (IV) iron.
A doctor may prescribe administering iron into a vein to increase iron levels in the blood, especially for patients with severe anemia who have a chronic condition, such as celiac disease.
The dosage of IV iron can differ depending on the intravenous iron formulation a doctor prescribes.
Dosages may range from 100 milligrams (mg) per dose of INFeD, the brand name for a compound called low-molecular-weight iron dextran, to 1,000mg of Monofer — the brand name for the compound iron isomaltoside.
The time it takes to administer the dose can range from 15 minutes to 6 hours.
IV iron may deliver iron into the blood more efficiently and in higher doses than iron supplements, which can result in better management of anemia symptoms.
Side effects may include:
- nausea and vomiting
- allergic reactions in rare cases
Some types of anemia, such as pernicious anemia, develop because the body is deficient in vitamin B12, which it requires to produce healthy blood cells.
The supplemental vitamin B12 increases levels of the vitamin, which stimulates blood cell production.
The dosage may depend on the severity and type of anemia.
Benefits of vitamin B12
- reduction of vitamin B12-deficiency anemia symptoms
- reduction of a compound called homocysteine, which scientists have linked to heart attack and stroke
- possible positive effects on cognitive function and energy, although more research is necessary
It is very unlikely for a person to overdose on B12. This is
ESA is a synthetic form of a hormone the kidneys naturally produce, called erythropoietin (EPO). EPO helps stimulate the creation of red blood cells.
In people with certain conditions, such as chronic kidney disease, EPO levels are low, which
A doctor can prescribe the medication and perform the injections themselves, or a person may be able to self-administer the injections at home.
The dosage depends on the underlying cause of the anemia and other factors.
For a person with chronic kidney disease-associated anemia, the dose may begin at
ESA may also increase the risk of certain cancers, such as cervical, lung, neck, and breast cancer.
In people who also undergo chemotherapy, side effects can include:
A doctor may prescribe other medications to treat underlying conditions that may contribute to or cause anemia. Many conditions may affect the production of red blood cells and cause anemia symptoms.
Medications for these conditions may include:
Below are the answers to some frequently asked questions about medication for anemia.
What is the best medication for anemia?
The best medication for anemia will depend on the type and severity of the condition. Iron supplements are the
What is the newest medication for anemia?
The medication is the first oral treatment for anemia caused by chronic kidney disease, and doctors may prescribe it for adults who have received at least 4 months of dialysis.
There are different types of anemia, each with different causes and levels of severity, that may require different types of medication.
Common medication types include iron supplements, IV iron therapy, erythropoiesis-stimulating agents (ESA), and vitamin B12. Doctors may also prescribe medication to treat underlying conditions.
There are potential benefits and side effects of medication for anemia. Common side effects include nausea, vomiting, and other gastrointestinal upsets.
