Darbepoetin Alfa Side Effects: An Introduction
As with any medicine, side effects are possible with
darbepoetin alfa (
Aranesp®); however, not everyone who takes the medication will experience side effects. In fact, most people tolerate it quite well. If side effects do occur, in most cases, they are minor and either require no treatment or can easily be treated by you or your healthcare provider.
(This article covers many, but not all, of the possible side effects with darbepoetin alfa. Your healthcare provider can discuss a more complete list of side effects with you.)
Serious Side Effects Seen With Darbepoetin Alfa
Some side effects of darbepoetin alfa, while occurring infrequently, are potentially serious and should be reported immediately to your healthcare provider.
These include, but are not limited to:
- High blood pressure (hypertension) or low blood pressure (hypotension)
- Signs of congestive heart failure (CHF), such as difficulty breathing, swelling or water retention, weight gain, or cough
- An irregular heart rhythm (arrhythmia) or a sudden loss in heart function (cardiac arrest)
- Heart attack, stroke, or blood clots
- Increased growth of cancers
- Seizures
- Signs of an allergic reaction, including unexplained rash, hives, itching, and unexplained swelling.
Serious darbepoetin alfa side effects seem to be more common if darbepoetin alfa therapy is too aggressive. The medication should be dosed using a specific target for hemoglobin levels (a measure of anemia). The target hemoglobin level is 12 g/dL, and the target should be achieved gradually. If a higher hemoglobin target is used (or if hemoglobin is raised too quickly), serious side effects are more likely.
