Drug Interactions With Diethylpropion

Blood Pressure Medications
Because diethylpropion can increase your blood pressure, it may make high blood pressure medications less effective. Your healthcare provider should monitor your blood pressure while you are taking diethylpropion and adjust the dose of your blood pressure medication as necessary.
Diabetes Medications
Since diethylpropion may affect how much you eat, your healthcare provider may need to adjust the dose of your diabetes medications while you are taking it.
Monoamine Oxidase Inhibitors
Taking diethylpropion and monoamine oxidase inhibitors together can cause life-threatening side effects, such as very high blood pressure. Do not take diethylpropion if you have taken an MAOI within the past 14 days.
Other Weight Loss Drugs
Diethylpropion should not be combined with any other weight loss medications.
Phenothiazines may make diethylpropion less effective by reducing the medication's effect on the appetite. Check with your healthcare provider before taking these medications together.
