Dalteparin Warnings & Precautions

Before taking Dalteparin, inform your doctor of all your medical conditions and medications. Certain conditions and patient groups require special precautions or may make Dalteparin unsuitable.

Key Warnings

→Carry anticoagulant card or alert bracelet
→Inform dentists and surgeons before any procedure
→Seek immediate care for any signs of serious bleeding
→Regular INR monitoring essential for warfarin

Pregnancy and Breastfeeding

→Heparin and low-molecular-weight heparins are the preferred anticoagulants in pregnancy as they do not cross the placenta. Warfarin is teratogenic especially in the first trimester. DOACs are contraindicated in pregnancy.

Older Adults

→Significantly increased bleeding risk, particularly intracranial haemorrhage, in older adults. Use lowest effective dose. Balance bleeding risk carefully against clot risk. Falls risk is a key consideration.

Chronic Conditions

→Renal impairment: DOACs accumulate — dose reduction or alternative required. Severe hepatic impairment: all anticoagulants require careful monitoring. Peptic ulcer: significantly increased GI bleeding risk.

When Not to Use

→Active major bleeding
→Recent neurosurgery or high-risk bleeding sites
→Severe uncontrolled hypertension
→Warfarin: pregnancy (especially first trimester)
→DOACs: pregnancy, severe renal impairment
