Been on fragmin (dalteparin) injections for a year. D-dimer showing normal but having the exact same symptoms of a pe again. So confused?

See your doctor: Fragmin (dalteparin) treatment for a year implies a significant coagulation problem, and your statement suggests that you have had prior pulmonary embolism. The d-dimer being normal, means there is no significant clot formation, but since you are having pulmonary symptoms again, you should see your doctor for help. ...Read more

I'm on fragmin (dalteparin) and I'm pregnant but the baby is sick and will not survive and I may miscarry. Will i hemerrage dangerously if this happens?

Likely no: From your history I see that you have a history of dvt. Women with this are typically on a 40mg dose of fragmin, (dalteparin) which is a prophylactic dose. Pregnancy actually increases your chances of blood clot, which you likely already know. If you likely are going to miscarry, consider making sure you're on a prophylactic dose, not a therapeutic dose of the medication. A therapeutic dose could hemorrhage. ...Read more

My fragmin/dalterparin daily injections are leaving hard lumps up to 2 inches at injection sight they don't seem to be going for weeks. Causes?

Bruise: Seem bigger than expected
check needle size, volume injected and talk with doc about possible overdosing.
While a goal of anti coagulation is important, local bleeding is uncomfortable and a possible sign of need for adjustment.

Ice may help earl, and heat later to limit bruise and resorb hematoma. ...Read more

I have a broken ankle and I am in a cast I have got a bruise near my toes it's little but has just appeared I am on fragmin (dalteparin) for 6 weeks what do I do?

They can determine the appropriate evaluation & if necessary remove the cast, image and test in the office and replace appropriately.

I have an allergy to nuts and I was wondering if my children would also be allergic?

I have an allergy to nuts and I was wondering if my children would also be allergic?

Nut allergy: Maybe. Your children may have inherited genes from you that make them more likely to develop an allergy, but they do not inherit a specific allergy to a food e.g. Nuts. The children have to be exposed to food proteins in the diet, before an allergy can develop. Once one develops an allergy then they are always allergic and need proper medical attention to prevent severe problems. ...Read more
