What are the drug interactions with weight loss drugs?
Phentermine may decrease the effectiveness of guanethidine.
Tenuate may interact with blood pressure medications, insulin, and other medications such as Thorazine.
Sibutramine should not be used with, or within two weeks of, monoamine oxidase inhibitors (MAOIs). Doing so may precipitate a serious and sometimes fatal side effect known as the "serotonin syndrome." Sibutramine can interact with other antidepressants, narcotic pain medication, antibiotics, and migraine medications.
Because sibutramine commonly raises blood pressure, patients should be carefully monitored for use of other drugs which can do the same â€“ such as over-the-counter cough, cold, and allergy preparations containing such ingredients as pseudoephedrine.
Orlistat may reduce levels of supplemental vitamins or medications such as cyclosporine. Patients taking both drugs should separate dosages by two hours.
