Here is a clear, actionable guide based on authoritative medical textbooks and current clinical guidelines:
Your Father is Having a Warfarin Bleeding Complication
Gum bleeding and bruising are signs that warfarin has thinned the blood too much - the INR (clotting test) is likely above the therapeutic range. This is a common but important situation that needs prompt attention.
Step 1 - Check for Emergency Warning Signs RIGHT NOW
Call emergency services (ambulance) IMMEDIATELY if he has any of these:
| Danger Sign | Why It Matters |
|---|---|
| Severe or uncontrolled gum bleeding that won't stop with pressure | May need reversal treatment in ER |
| Headache, confusion, weakness, slurred speech, or vision changes | Could be bleeding in the brain |
| Vomiting blood or blood in stools (black/tarry stools) | Internal GI bleeding |
| Large or rapidly expanding bruise | Significant internal bleeding |
| Chest pain or coughing blood | Serious internal bleeding |
| Difficulty breathing | Emergency |
Step 2 - What to Do Right Now at Home
If the symptoms are mild (small bruise, slight gum bleeding that slows with pressure):
- Stop today's warfarin dose - do not give another dose until the INR is checked
- Apply pressure to the gum - use clean gauze, press firmly for 10-15 minutes without peeking
- Do NOT give aspirin or ibuprofen (NSAIDs) - these make bleeding worse
- Paracetamol (acetaminophen) is safe for any pain
- Go to a clinic or ER TODAY for an urgent INR blood test - do not wait until tomorrow
Step 3 - What the Doctor Will Do (Based on INR Result)
According to Harrison's Principles of Internal Medicine and clinical guidelines:
| INR Level | Action |
|---|---|
| Slightly above range (3.5-4.5) with mild bleeding | Skip 1-2 doses of warfarin, recheck INR in 1-2 days |
| INR 4.5-10 with bleeding | Skip warfarin + give oral Vitamin K (1-2.5 mg) to reverse it |
| INR >10 with active bleeding | Skip warfarin + give Vitamin K 5-10 mg IV + possibly Prothrombin Complex Concentrate (PCC) or fresh frozen plasma in hospital |
"Patients with an increased INR associated with serious bleeding should be given 5-10 mg of Vitamin K by slow IV infusion supplemented with fresh frozen plasma or PCC depending on the urgency of the situation." - Harrison's Principles of Internal Medicine, 22E
Why This Happens - Common Causes
If the INR jumped suddenly, ask your father if he recently:
- Started or stopped any new medication (antibiotics like metronidazole, fluconazole, amiodarone, and many others dramatically increase warfarin's effect)
- Ate unusually large amounts of foods rich in Vitamin K (broccoli, spinach, kale) - OR suddenly ate much less of these
- Had diarrhea, vomiting, or poor appetite (reduces Vitamin K absorption)
- Missed doses then doubled up
- Changed his alcohol intake
When to Be Reassured
Minor gum bleeding and a small single bruise with NO other symptoms is usually manageable - but it still must be evaluated today with an INR test. The doctor may simply hold one dose and adjust his weekly warfarin dose.
Bottom Line - Action Plan
- Mild/no emergency symptoms -> Go to a clinic or ER today for INR check. Hold today's warfarin dose.
- Any of the danger signs above -> Call emergency services immediately.
- Tell the doctor all medications your father takes - something may have interacted with his warfarin.
