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 Fraxiparine (Nadroparin).

Bleeding: The most serious risk associated with Fraxiparine (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, have liver failure, reduced kidney function, high blood pressure, or a history of ulcers), your doctor should closely monitor your condition while you are taking Fraxiparine (Nadroparin).

Body weight: The safety and efficacy of Fraxiparine (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 Fraxiparine (Nadroparin).

Cardiovascular problems: If you have Coronary Artery Disease or high blood pressure, discuss with your doctor how Fraxiparine (Nadroparin) may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Fraxiparine (Nadroparin), and whether any special monitoring is needed.

Kidney function: Kidney Disease or reduced kidney function may cause Fraxiparine (Nadroparin) to build up in the body, causing side effects, including bleeding. If you have reduced kidney function or kidney disease, discuss with your doctor how Fraxiparine (Nadroparin) may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Fraxiparine (Nadroparin), and whether any special monitoring is needed.

Platelets: While you are using Fraxiparine (Nadroparin), your doctor will also be monitoring your platelet count. If your platelet level drops very suddenly, you may have to stop Fraxiparine (Nadroparin) and switch to another type of medication. Make sure to tell doctors involved in your care if you have had any problems with low platelets or platelet defects in the past.

Potassium levels: Fraxiparine (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 Fraxiparine (Nadroparin). If you experience symptoms of high levels of potassium in the blood, such as muscle fatigue, weakness, difficulty moving, abnormal heart rhythms, or nausea, contact your doctor.

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 Fraxiparine (Nadroparin). Your doctor will need to monitor you closely while you are taking Fraxiparine (Nadroparin).

Stomach ulcers: If you have a history of stomach ulcers or bleeding in the digestive system, Fraxiparine (Nadroparin) may cause the condition to reoccur. If you have any symptoms of bleeding in the digestive system, such as bloody, black, or tarry stools, spitting up of blood, vomiting blood or material that looks like coffee grounds, seek medical help immediately.

Pregnancy: The medication should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking Fraxiparine (Nadroparin), contact your doctor immediately.

Breast-feeding: It is not known if Fraxiparine (Nadroparin) passes into breast milk. If you are a breast-feeding mother and are taking Fraxiparine (Nadroparin), it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.

Children: The safety and effectiveness of using Fraxiparine (Nadroparin) have not been established for children.

Seniors: People over the age of 65 years are more at risk of bleeding from Fraxiparine (Nadroparin).
