Learn about our Medical Review Board Print BSIP/UIG/Getty Images Bupropion is a drug primarily used as an antidepressant or smoking cessation tool. It is marketed under the brand name Wellbutrin when used in the treatment of major depressive disorder and seasonal affective disorder. When used for smoking cessation, it is marketed under the brand name Zyban. In either form, bupropion is associated with a number of common side effects: AgitationBlurred visionConstipationDizzinessDry mouthExcessive sweatingHeadacheNausea and vomitingRapid heartbeat One of the less common heart-related side effects is hypertension (high blood pressure). Although one trial actually showed a decrease in blood pressure over the course of the study with Wellbutrin, there have been studies that report some increase in treatment-emergent hypertension with Wellbutrin, particularly when used with nicotine replacement for smoking cessation. Understanding Hypertension Hypertension is a condition in which the force of the blood against the artery walls is too high. The elevated pressure with these vessels places a strain on the cardiovascular system as a whole and, over time, increases a person's risk of heart attack, aneurysm, kidney disease, and stroke. Normal blood pressure is defined as a systolic pressure below 120 mmHg and a diastolic value under 80 mmHg. Although sometimes defined differently, hypertension is blood pressure that is consistently greater than 130 systolic and 80 diastolic. Depending on the systolic pressure (during a heartbeat) and diastolic pressure (between heartbeats), the severity of hypertension could be classified as: Stage 1: between 130 and 139 systolic and 80 and 89 diastolicStage 2: 140 or higher systolic and 90 or higher diastolicHypertensive crisis: 180 or higher systolic or 120 or higher diastolic Bupropion and Hypertension Bupropion has the potential to increase blood pressure because it affects the levels of certain neurotransmitters, known as catecholamines, which regulate not only mood but blood pressure. The risk of hypertension is known to increase to 6.1% (or roughly one of every 16 people) if bupropion is taken in conjunction with a transdermal nicotine patch. This appears true whether a person has had a prior history of hypertension or not. If you must remain on Wellbutrin to control your depression, high blood pressure medication can be prescribed to counteract this side effect. Otherwise, you may need to speak with your doctor about switching to a different antidepressant. A Word From Verywell Bupropion can be an effective tool for treating depression or smoking addiction. Persons prescribed with Zyban or Wellbutrin should have their blood pressure tested before starting treatment and routinely monitored thereafter. If you experience any symptoms of hypertension, speak with your doctor. You can also get your blood pressure tested at most larger retail pharmacies.
