When vitamin E is used together with the following five drugs, it must be carried out under the guidance of a doctor. Don't take it yourself.
Aspirin: Both vitamin E and aspirin can reduce blood viscosity, so when taking vitamin E and aspirin at the same time, the doctor should adjust the patient's dose according to the specific situation.
Vitamin K: Vitamin E has antagonistic effect on vitamin K, which can inhibit platelet aggregation and reduce blood coagulation. Therefore, please don't take vitamin E before operation or while taking anticoagulant drugs.
Digitalis: Vitamin E can enhance the cardiotonic effect of digitalis. Patients who use such drugs should use vitamin E with caution to avoid digitalis poisoning.
Neomycin: drugs that affect absorption, such as neomycin, will affect the absorption of vitamin E, so taking them at the same time may reduce the efficacy of both.
Estrogen: Long-term high-dose (more than 400mg per day) taking vitamin E, especially when combined with estrogen, can induce thrombophlebitis, so we should be vigilant.
In addition, if vitamin E is taken together with acetone benzyl hydroxycoumarin (a coagulant), it will increase the possibility of abnormal bleeding. Cholesterol-lowering drugs called bile acid chelating agents (such as coletipol and coleenamine) will reduce the absorption of vitamin E, which will interact with cyclosporine (a drug for treating cancer) and reduce its curative effect.
