One example is the common allergy drug diphenhydramine (also known by the brand name Benadryl).

Jantoven Patient Information including If I Miss a Dose

What happens if I miss a dose (Jantoven)?

Take the missed dose as soon as you remember, and call your doctor as soon as possible. Do not take two doses at the same time to make up a missed dose.

What happens if I overdose (Jantoven)?

Seek emergency medical attention if you think you have used too much of this medicine.

Overdose symptoms may include bruising, broken blood vessels under the skin, excessive bleeding from cuts or wounds, blood in the urine or stools, and heavy menstrual periods in women.

What should I avoid while taking warfarin (Jantoven)?

You should not take acetaminophen (Tylenol), aspirin, or NSAIDs (non-steroidal anti-inflammatory drugs) unless your doctor has told you to. NSAIDs include celecoxib (Celebrex), diclofenac (Voltaren), ibuprofen (Motrin, Advil), indomethacin, naproxen (Aleve, Naprosyn), piroxicam (Feldene), and others.These medicines may affect blood clotting and could cause serious bleeding in your stomach or intestines.

Avoid sudden changes in your diet. Vitamin K decreases the effects of warfarin. Large amounts of vitamin K are found in foods such as liver, broccoli, brussels sprouts, spinach, Swiss chard, coriander, collards, cabbage, and other green leafy vegetables. Do not change the amount of these foods in your diet without first talking to your doctor.

Avoid eating cranberries, drinking cranberry juice, or taking cranberry herbal products.

Avoid drinking alcohol, which can increase some of the side effects of this medication.

Avoid sports or activities that could result in a bruising or bleeding injury. Use extra caution to avoid cuts when brushing your teeth or shaving.

What other drugs will affect warfarin (Jantoven)?

Warfarin interacts with many other drugs, and these interactions can be dangerous, even fatal. Tell your doctor about all the prescription and over-the-counter medications you use. This includes vitamins, minerals, herbal products, and drugs prescribed by other doctors. Do not start using a new medication without telling your doctor. Keep a list with you of all the medicines you use and show this list to any doctor or other healthcare provider who treats you.

Warfarin can interact with the following herbal (botanical) products:

bromelains;
coenzyme Q10;
danshen;
dong quai;
garlic;
ginkgo biloba;
ginseng; or
St. John's wort.

Do not use any of these products without first asking your doctor. Some of these herbal products can cause you to bleed while you are also taking warfarin.
