Can Coumadin (warfarin) cause a skin rash?

Can Coumadin (warfarin) cause a skin rash?

Occasionally: Virtually all medications can be associated with rash. Rashes due to medications may be the result of non-medicinal carriers that do not effect efficacy. Sometimes changing the source of a medication can reduce the risk of rash. Coumadin (warfarin) may also cause a rare but serious condition of the skin called coumadin-induced skin necrosis. ...Read more

On warfarin after saddle PE 2 yr ago goal inr is 3 wk ago it was over 10 but now back to 3.2 iv vomit last 2 days with small amount of red blood in it?

On warfarin after saddle PE 2 yr ago goal inr is 3 wk ago it was over 10 but now back to 3.2 iv vomit last 2 days with small amount of red blood in it?

WarfarinDoesNotThin: Blood. Like all these mis-described agents, it slows clotting (warfarin by ↓ing 4of12 clotting proteins) thus bleeding takes longer to stop & more blood lost. Blood in vomit (from trauma of vomiting) due to ↑ed bleeding, thus apparent. INR (Nl=1.0)=a way of expressing how much clotting has slowed. Xarelto (works differently, INR does not show; not needed) = more effective&safer anti-clotting tool. ...Read more

How long after begin off Coumadin (warfarin) can I start back enjoying vitamin K foods and red wine?

How long after begin off Coumadin (warfarin) can I start back enjoying vitamin K foods and red wine?

Immediately for K...: The reason to avoid vit k on Coumadin (warfarin) is that it reduces the effectiveness of Coumadin (warfarin) (though I advise people eat consistent levels of food with k & adjust Coumadin (warfarin) dose accordingly) so you can eat k right away. Alcohol can thin the blood so one should limit to 2 glasses of wine/day while on it. Within 5 days of stopping (sooner if you eat k foods) Coumadin (warfarin) is out of your body so occ. More is ok. ...Read more

My dad is taking Coumadin (warfarin) and both his legs are swollen and hot and painful to touch and he has a long red line going down one leg.?

Thrombophlebitis: Superficial thrombophlebitis is inflammation of a vein just under the skin, usually in the leg. A small blood clot also commonly forms in the vein, but is usually not serious. The condition usually settles and goes within 2-6 weeks. Treatments can ease pain or discomfort. Superficial thrombophlebitis is different to, and much less serious than, deep vein thrombosis. Still must be evaluated. ...Read more

Other symptoms?: You may be describing a resolving or an ongoing hematoma.

Mom DX with clot last year. On coumadin (warfarin) and her level is 1.9. Leg with clot is now swollen like it was the day in the ER. Not hot not red, but worried.

Get an US leg: Her Coumadin (warfarin) level is OK, though slightly lower. If her leg with clot is now swollen again, she should go to ER and get another US (ultrasound) for evaluation. Not commonly, sometimes we do see new clot develops on therapeutic INR (2-3). ...Read more

Blood clotting levels on taking warfarin, have red eye, reduce or increase dosage?

Blood clotting levels on taking warfarin, have red eye, reduce or increase dosage?

Too many cooks: The doc who monitors your warfarin needs to know about any bleeding & should be the only one to advise you on dosage. If red eye is just prominent blood vessels that doesn't sound like a bleed, just an irritation. If it's a patch of red that could be a subconjunctival hemorrhage and your doc will want to know and maybe recheck your inr. ...Read more

Hv hep c, liver cirohsis, gall bladder stone, taking Coumadin (warfarin), bleeding through stools. Red colour...What could b the reason.?

Gi bleed: If you have chronic hcv infection, liver cirrhosis, and coumadin, (warfarin) you are at risk for GI bleed. Patients with liver cirrhosis likely have portal hypertension and low effective circulating platelets, which increased risks of bleeding. Coumadin (warfarin) will increase this risk.

Causes of redness in pubic area red rash bit of a burning after showering

This: This sounds like an allergic reaction. Are you using any new soaps, shower gels?
