Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Bleeding: The most serious risk associated with nadroparin is bleeding in any tissue or organ. It is extremely important to have regular blood tests (as prescribed by your doctor) to ensure that the correct level of blood thinning is occurring. If you have an increased risk of bleeding (for example, if you are over 65), your doctor should closely monitor your condition while you are taking this medication.
Body weight: The safety and efficacy of nadroparin for very heavy people (e.g., over 120 kg) and very light people (e.g., under 45 kg) have not been fully established. If your weight is very high or low, your doctor will monitor you closely while you are taking this medication.
Medical conditions: If you have coronary artery disease, high blood pressure, kidney problems, or liver problems, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Platelets: While you are using nadroparin, your doctor will also be monitoring your platelet count. If your platelet level drops very suddenly, you may have to stop this medication and switch to another type of medication. Make sure to tell your doctor if you have had any problems with low platelets or platelet defects in the past.
Potassium levels: Nadroparin may increase blood potassium levels, especially in people who are at risk for high potassium levels (e.g., people with diabetes or who take certain medications). Your doctor will monitor your potassium levels while you are using this medication.
Prosthetic heart valves: There have been reports of people with prosthetic heart valves who developed clots in their valves when treated with low-molecular-weight heparin medications such as nadroparin. Your doctor will need to monitor you closely while you are taking nadroparin.
Pregnancy: The medication should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking this medication, contact your doctor immediately.
Breast-feeding: It is not known if nadroparin passes into breast milk. If you are a breast-feeding mother and are taking this medication, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.
Children: The safety and effectiveness of using this medication have not been established for children.
