ADHD Medication and Treatment Reviews

Wellbutrin (bupropion HCL)

Wellbutrin is not an FDA-approved ADHD medication, but rather an antidepressant sometimes used off label to treat ADHD symptoms including hyperactivity and distractibility in people with attention deficit hyperactivity disorder.
Generic Name: bupropion HCL

What is bupropion HCL?

Bupropion HCL is an antidepressant medication primarily used to treat major depressive disorder and seasonal affective disorder in adults. Its safety has not been established for children or young adults under the age of 18.

Bupropion is available as different medications with different medication durations, including:

Bupropion HCL may help to relieve common symptoms of depression including disinterest in typical activities, impaired concentration, change in weight or appetite, and insomnia.

While bupropion may not be as effective as stimulants, it is effective for treating ADHD, as a number of studies have indicated.1,2, 3, 4

Physicians sometimes prescribe brand name Wellbutrin “off-label” to treat ADHD symptoms.

However, Wellbutrin is not often the first drug used to treat ADHD.  I would use Wellbutrin only in those unusual cases where the side effects to stimulants (especially mood related side effects, anxiety, obsessive-copulsive behaviors) cannot be managed on stimulants alone).

When prescribed for ADHD treatment, it can be prescribed in conjunction with a stimulant medication like Vyvanse or Adderall XR.

How Do You Use Wellbutrin to Treat ADHD?

Before starting or refilling a Wellbutrin prescription, have a conversation with your doctor, who has a holistic view of your medical history, other diagnoses, and other prescriptions. If you have questions, ask your doctor or pharmacist before you begin taking the medication.

What Is the Dosage for Wellbutrin?

As with all medications, follow your Wellbutrin prescription instructions exactly. Wellbutrin is taken orally, with or without food. It is available in three formulations:

  • Wellbutrin (standard): Only lasts about six hours per dose, so at least two or three dosages per day are necessary.
  • Wellbutrin SR (sustained release): Taken once or twice daily with at least six hours between doses.
  • Wellbutrin XL (extended release): Taken once daily with at least 24 hours between doses. The time-release formulation is designed to maintain a steady level of medication in your body throughout the day.

The optimal dosage of Wellbutrin varies by patient. For updated information about dosages, interactions, and precautions, see the Wellbutrin drug monograph on WebMD.

Initially, bupropion was not designed to treat ADHD, and it has not been studied very often in children.  As a result, achieving appropriate dosage can be difficult, especially in children under 10 years of age.  Wellbutrin SR and Wellbutrin XL come in large dosage increments and since these medications cannot be cut or chewed, it is not possible, for example, to give Wellbutrin XL in a dosage greater than 150mg and less than 300mg.

If you miss a dose, wait to take your next dose at the scheduled time. You should not take two doses of Wellbutrin at the same time.

The risk of seizures is highly dose-dependent, and is no higher than other antidepressants. Taking too much Wellbutrin can increase risk of seizures. It is only when a daily dose goes above 450mg that the incidence of seizures climbs to 5%5. When beginning treatment with Wellbutrin, a patient’s dose should be increased gradually to minimize the risk of seizure.

Do not drink alcohol while taking this drug.

The optimal dosage varies patient by patient and condition treated. If you are over 60 years of age, or have certain health conditions, your doctor may recommend a lower dosage.

Your doctor may incrementally adjust your daily dosage until you experience the best response — that is, until you find the lowest dosage at which you experience the greatest improvement in symptoms without side effects.

When discontinuing treatment, or decreasing dosage, patients should work with a doctor to gradually taper the level of medication. Stopping antidepressant medications suddenly can cause new symptoms.

What Side Effects Are Associated with Wellbutrin?

Most people taking this medication do not experience any of these side effects.

The most common side effects of Wellbutrin are similar to those associated other antidepressant medications, and are as follows: agitation, dry mouth, nervousness, constipation, headache, nausea and vomiting, difficulty sleeping, dizziness, pharyngitis, muscle pain, shakiness, fast heartbeat, and heavy sweating.

Other serious side effects include increased risk of suicide or suicidal thoughts, seizures, and angle-closure glaucoma.

Taking Wellbutrin may impair your ability to drive, operate machinery, or perform other potentially dangerous tasks. This side effect usually wears off with time. If side effects are bothersome, or do not go away, talk to your doctor.

Disclose to your physician all mental health issues including any family history of suicide, bipolar disorder, mania, or depression. The manufacturer, Valeant, recommends evaluating patients for bipolar disorder prior to administration of Wellbutrin to avoid inducing a manic episode. Wellbutrin may create new or exacerbate existing behavior problems, bipolar disorder, or suicidal ideation, especially in the first few months of treatment or after a dosage change. Call your doctor immediately if you experience new or worsening mental health symptoms including reckless behavior, hallucinations, or sudden excessive happiness or irritability.

Report to your doctor any heart-related problems or a family history of heart and blood pressure problems. Wellbutrin can increase blood pressure. Physicians should monitor these vital signs closely during treatment.

The above is not a complete list of potential side effects. If you notice any health changes not listed above, discuss them with your doctor or pharmacist.

What Precautions Are Associated with Wellbutrin?

Store Wellbutrin in a secure place out of the reach of children, and at room temperature. Do not share your Wellbutrin prescription with anyone, even another person with depression. Sharing prescription medication is illegal, and can cause harm.

You should not take Wellbutrin if you:

  • have or had a seizure disorder or epilepsy
  • have or had an eating disorder
  • are taking other medications containing bupropion
  • drink a lot of alcohol or have recently stopped abusing alcohol
  • take a monoamine oxidase inhibitor (MAOI)
  • are allergic to bupropion or any of the ingredients in Wellbutrin

You should use caution taking Wellbutrin, and speak with your doctor if you have liver or kidney problems, seizures, bipolar disorder, a history of tumors or heart problems, or diabetes.

If you’re thinking of becoming pregnant, discuss the use of Wellbutrin with your doctor. Animal studies indicate potential risk to the developing fetus. Wellbutrin is passed through breastmilk, so it is recommended that mothers do not nurse while taking it.

Wellbutrin is not approved for use in pediatric patients.

What Interactions Are Associated with Wellbutrin?

Before taking Wellbutrin, discuss all other active prescription medications with your doctor. Wellbutrin can have a dangerous, possibly fatal, interaction with certain antidepressants including MAOIs.

Wellbutrin inhibits CYP2D6 enzyme, which can change how your body processes certain medications including venlafaxine, nortriptyline and more. It can impact the dosage required for CYP2B6 inducers including ritonavir, carbamazepine, and more. Wellbutrin can interact with certain dopaminergic drugs like levodopa and amantadine.

Wellbutrin can exacerbate the drowsiness created by depressants including alcohol, barbiturates, antihistamines, or other sedatives.

Share a list of all vitamin or herbal supplements, and prescription and non-prescription medications, you take with the pharmacist when you fill your prescription, and let all doctors and physicians know you are taking Wellbutrin before having any surgery or laboratory tests. Wellbutrin can give a false positive for amphetamines.

The above is not a complete list of all possible drug interactions.
