Lovenox Side Effects
Serious Side EffectsSome Lovenox side effects are potentially serious and should be reported immediately to your healthcare provider. Most of the serious problems are related to bleeding, an inherent risk with "blood-thinning" medications. Some of the warning signs of these serious reactions include:
- Unusual headaches, dizziness, or weakness
- Unusual bruising (bruises that develop without known cause or grow in size)
- Blood in the urine
- Blood in the stool (usually seen as red or black stools)
- Bleeding gums
- Bleeding from cuts that takes a long time to stop
- Menstrual bleeding or vaginal bleeding that is heavier than normal
- Coughing up blood.
Heparin-like medications (such as Lovenox) may also cause a serious problem known as heparin-induced thrombocytopenia (HIT). HIT is a reaction to heparin (or heparin-like medications) in which the body develops antibodies to the medication. These antibodies activate blood platelets, increase the risk of blood clots, and decrease the measurable platelet levels in the blood.
There are often no noticeable symptoms of HIT until clotting begins to occur, and HIT can be deadly. For this reason, your healthcare provider may wish to monitor your blood platelets when you first start taking Lovenox (or another heparin-like medication).
Although Lovenox appears to be less likely to cause HIT than regular (unfractionated) heparin, there is still a small risk of this problem.
Final ThoughtsYou may experience some or none of the Lovenox side effects listed in this article. Unfortunately, there is no way for your healthcare provider to know beforehand if you will have problems with a medicine that you have never tried.
Therefore, make sure to let your healthcare provider know if you develop any adverse reactions while taking the drug or if something "just does not seem right." While it may not be a side effect of Lovenox, your healthcare provider will be able to diagnose and treat the problem.
