Phentermine and Warfarin

Warfarin and phentermine interactionsPhentermine and warfarin are two drugs that are very common in the market. Phentermine is given to patients who have a high BMI where as people with cardiovascular diseases use warfarin. Both affect separate art of the body and hence there are no ways in which they must interfere. Let us make a comprehensive analysis of the two drugs and the effects they produce while they are in combination.

About Phentermine

Phentermine is a prescription drug that is given to people who wish to decrease their weight. When it is included with a proper exercise regime it can help to decrease the body weight. They increase the metabolic rate and hence you can burn more calories from the same time you are spending on exercise. It further helps to suppress the appetite and for people who are suffering from eating disorders along with abnormal weight can take this pill. But it must only be used for a very short span of time because it gives way to ugly side effects. These side effects can be reversed with alternate medication but as soon as one starts experiencing these side effects one must immediately bring it to the notice of the doctor who has prescribed this medicine. Some of the effects are as follows-

  • Increase in the blood pressure due to which the heart may be affected.
  • Loss of libido because it has an effect on the endocrine glands.
  • It causes dizziness and lack of muscle coordination. It has an effect on the central nervous system. This is the reason people who are taking this medicine must abstain from potentially hazardous jobs.
  • Gastrointestinal problems may also creep in like dryness of mouth, constipation or even diarrhoea.
  • It may also cause muscle spasms and if not treated it may get really severe.


About Warfarin

The active ingredient in Warfarin is warfarin sodium and it is prescribed to patients who have cardiovascular diseases and who want to keep their clotting low. It decreases the chances of the coagulation of blood and hence keeps away an attack or thrombosis. People who have an abnormal clotting factor can use this drug because it does not let the blood clot. Even people with weak valves are given this drug in a regular basis like problems of the mitral valves or aortic valve. Patients with artificial devises for supporting the heart like pacemaker too use this anti-clotting drug in a regular basis.

Both Phentermine and Warfarin can be taken together because they do not come in the way of each other. Both work separately and do not have contraindications. Yet it is advisable that you note all that you are feeling while you have started taking Warfarin along with phentermine. In case there are any sudden changes you must bring it into the notice of the medical practitioner without stopping any of the drugs. But such cases are rare and very often it is seen that it is not from the interaction of the drugs.

You must of course inform your doctor in case you are taking Phentermine or warfarin from before, because he will then make a complete analysis and tell you the exact safety in the use of the drugs.[divider scroll_text=”Back to Top”]
