Why do doctors give injections of vitamin K when patients are taking warfrin?

Why do doctors give injections of vitamin K when patients are taking warfrin?

For toxicity: If warfarin is well controlled and INR levels are therapeutic (2-3.5, depending on the disease being treated), Vitamin K is NOT needed. It is only used when the effect of the warfarin needs to be reversed FAST as the patient is bleeding or about to bleed. That is why monitoring levels is so important. ...Read more

Depends: Some chemotherapy drugs would lose effectiveness if you were to take vitamins. For example methotraxate works by blocking the action of folic acid. If you were to take vitamin supplement containing folic acid, it would negate the effect of methotraxate.

I was advised to avoid Vit C prior to having fillers, Juvederm. Is that for actual Vit C supplement or should I also avoid foods containing vitamin C?

I was advised to avoid Vit C prior to having fillers, Juvederm. Is that for actual Vit C supplement or should I also avoid foods containing vitamin C?

Vitamin C: There is no reason to stop Vitamin C before having HA facial fillers. If you want to avoid bruising, stop all aspirin containing medications or foods that can retard normal coagulation (green tea, garlic etc.). I do advise stopping Vitamin E. May be that is what they meant. I also recommend arnica montana for 3-5 days prior to the injection. ...Read more

How much vitamin d 3 & vitamin K should a woman take daily ? I am bruising easily and wanted to know if vitamin K will help so i won;;t bruise easy ?

Depends: Vitamin d intake depends on your blood level. Some people need more than others; their body breaks it down faster. It will not have any effect on bruising. Vitamin k is in leafy green vegetables which you should be eating daily. Vitamin k is also in many multivitamins. Vitamin k deficiency is very rare unless you have unusual medical problems so look for other causes of bruising. See your doctor. ...Read more

MY VITAMIN D IS 23 L IS IT OK TO STILL TAKE MY MULTIVITAMIN THAT HAS 400IU VITAMIN D & WANT TO TAKE VITAMIN D3 1000 ?

MY VITAMIN D IS 23 L IS IT OK TO STILL TAKE MY MULTIVITAMIN THAT HAS 400IU VITAMIN D & WANT TO TAKE VITAMIN D3 1000 ?

Not a problem: The amount of vitamin D in a multivitamin is a small daily requirement dose. If you are being prescribed a supplement for low vitamin D levels, the amount in your daily vitamin is not significant. You can continue it without worry. Please don't treat your own vitamin D levels - too much vitamin D can have toxic side effects as it builds up in your body. ...Read more

As per week i am taking vitamin d 3drops glucophage also as u say it should not take with vitamins should i wait to complete my vitamin d course of2 m?

It's OK: Hi. I don't know who told you you can't take metformin with vitamins, but that is utterly incorrect. It is true that vitamin D is better absorbed if taken with food, and that metformin's tolerability (at least early on) may be better if taken with food. It is NO PROBLEM to take metformin and vitamin D together. Bon appétit! ...Read more

You may need a larger dose than the 800iu daily to really increase your levels in a sufficient way.

My vitamin d level is 18 ..why vitamin d supplement gives me horrible muscle cramps ..should I take calcium with vitamin d or take vitamin d only ?

Unusual response: This is a very unusual reaction to Vit D. You are more likely to be reacting to the other ingredients in the supplement so look for a pure Vit D3 with minimal additives. Most adults need 5-8000 iu/day to get optimal levels of 50-80. You probably don't need calcium unless your diet is low in calcium but it is wise to take Vit K with Vit D. Muscle cramps may be caused by low Magnesium. See comment: ...Read more
