Wellbutrin Xl
+ Vyvanse
The following applies to the ingredients: Bupropion (found in Wellbutrin Xl) and Lisdexamfetamine (found in Vyvanse)
Professional Content
MONITOR: Coadministration with inhibitors of CYP450 2D6 may increase the plasma concentrations as well as the pharmacologic and adverse effects of amphetamines. The proposed mechanism involves the inhibition of CYP450 2D6, an isoenzyme partially responsible for the metabolic clearance of certain amphetamines. Furthermore, because CYP450 2D6 is genetically polymorphic, variations in amphetamine metabolism across populations may either increase or decrease the risk associated with this interaction. Increased exposure to amphetamines may potentiate the risk of serious adverse reactions such as serotonin syndrome, seizures, psychiatric adverse reactions (e.g., new psychotic or manic symptoms), peripheral vasculopathy (including Raynaud's Phenomenon), and cardiovascular effects (e.g., hypertension, tachycardia). However, data evaluating the interaction are not available.
MANAGEMENT: Caution and closer monitoring for adverse effects are recommended when amphetamines are used concurrently with CYP450 2D6 inhibitors, and a reduction in the initial amphetamine dose should be considered. Patients should be more closely monitored for signs and symptoms of serotonin syndrome, particularly during the initiation of amphetamine therapy and following any dosage increases. Additional caution is advised when amphetamines are coadministered with CYP450 2D6 inhibitors that lower the seizure threshold (e.g., bupropion). Patients should be instructed to notify their healthcare provider if they experience increased amphetamine-related side effects, such as seizures, cardiovascular effects (e.g., hypertension, tachycardia), or symptoms of serotonin syndrome (e.g., mental status changes, autonomic dysfunction like tachycardia or hyperthermia, neuromuscular abnormalities such as hyperreflexia, or gastrointestinal symptoms).

Drug and Food Interactions
Moderate
Wellbutrin Xl
+ Food
The following applies to the ingredients: Bupropion (found in Wellbutrin Xl)
Using buPROPion with alcohol may increase the risk of uncommon side effects such as seizures, hallucinations, delusions, paranoia, mood and behavioral changes, depression, suicidal thoughts, anxiety, and panic attacks. On the other hand, sudden withdrawal from alcohol following regular or chronic use can also increase your risk of seizures during treatment with buPROPion. If you are prone to frequent or excessive alcohol use, talk to your doctor before starting buPROPion. In general, you should avoid or limit the use of alcohol while being treated with buPROPion. Also avoid activities requiring mental alertness such as driving or operating hazardous machinery until you know how the medication affects you. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
The following applies to the ingredients: Bupropion (found in Wellbutrin Xl)
Both buPROPion and caffeine can increase blood pressure. And using them together may have additive effects. Talk to your doctor if you have any questions or concerns, particularly if you have a history of high blood pressure or heart disease. Your doctor may be able to prescribe alternatives that do not interact, or you may need a dose adjustment or more frequent monitoring to safely use both medications. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
The following applies to the ingredients: Bupropion (found in Wellbutrin Xl)
Using buPROPion and nicotine together can cause an increase in blood pressure. This can cause dizziness, confusion, uneven heartbeats, and chest pain. If you take both medications together, tell your doctor if you have any of these symptoms. You may need a dose adjustment or need your blood pressure checked more often if you take both medications. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
Moderate
Vyvanse
+ Food
The following applies to the ingredients: Lisdexamfetamine (found in Vyvanse)
Using lisdexamfetamine together with alcohol can increase the risk of cardiovascular side effects such as increased heart rate, chest pain, or blood pressure changes. You should avoid or limit the use of alcohol while being treated with lisdexamfetamine. Let your doctor know if you experience severe or frequent headaches, chest pain, and/or a fast or pounding heartbeat. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
Drug and Pregnancy Interactions
Major
Wellbutrin Xl
+ Pregnancy
The following applies to the ingredients: Bupropion (found in Wellbutrin Xl)
Professional Content
This drug should be used during pregnancy only if the potential benefit outweighs the potential risk to the fetus. Smoking cessation without the use of medications is advisable during pregnancy.
AU TGA pregnancy category: B2
US FDA pregnancy category: C
Comments:
-A pregnancy exposure registry is available.
-Neonates exposed to this drug late in the third trimester may require respiratory support, tube feeding, and/or prolonged hospitalization.
-Exposed neonates should be monitored after delivery for direct toxic effects of this drug, drug discontinuation syndrome, and serotonin syndrome (e.g.,. respiratory distress, cyanosis, apnea, seizures, temperature instability, feeding difficulty, vomiting, hypoglycemia, hypo/hypertonia, hyperreflexia, tremor, jitteriness, irritability, constant crying).
High dose animal studies have failed to reveal evidence of specific teratogenic effects. Low dose animal studies in rabbits have reported a slightly increased incidence of fetal malformations and skeletal variations. Epidemiological studies of pregnant women exposed to bupropion in the first trimester show no increased risk of congenital malformations overall.
Data from the international bupropion pregnancy register (675 trimester exposures) and a retrospective cohort study using the United Healthcare database (1,213 first trimester exposures) and a case-control study from the National Birth Defects Prevention Study (6,853 infants with cardiovascular malformations and 5,763 with non-cardiovascular malformations) did not show an increased risk for malformations overall after bupropion exposure during the first trimester. A retrospective database of infants (n=7005) whose mothers were exposed to bupropion in the first trimester and outside of the first trimester also failed to reveal an increased risk for congenital malformation, especially cardiovascular malformation. Study findings on the risk for left ventricular outflow tract obstruction and ventricular septal defect after first trimester exposure to bupropion are inconclusive.
To monitor maternal-fetal outcomes of pregnant women exposed to antidepressant therapy, a National Pregnancy Registry for Antidepressants has been established. Healthcare providers are encouraged to prospectively register patients. For additional information: https://womensmentalhealth.org/clinical-and-research-programs/pregnancyregistry/antidepressants/
AU TGA pregnancy category B2: Drugs which have been taken by only a limited number of pregnant women and women of childbearing age, without an increase in the frequency of malformation or other direct or indirect harmful effects on the human fetus having been observed. Studies in animals are inadequate or may be lacking, but available data show no evidence of an increased occurrence of fetal damage.
US FDA pregnancy category C: Animal reproduction studies have shown an adverse effect on the fetus and there are no adequate and well-controlled studies in humans, but potential benefits may warrant use of the drug in pregnant women despite potential risks.

The following applies to the ingredients: Lisdexamfetamine (found in Vyvanse)
Professional Content
Benefit should outweigh risk.
AU TGA pregnancy category: B3
US FDA pregnancy category: C
Comments:
-The active metabolite of this drug, dexamphetamine, crosses the placenta.
-Premature delivery, low birth weight, and other adverse pregnancy outcomes have been seen in infants born to mothers dependent on amphetamines.
-Monitor infants born to mothers taking amphetamines for symptoms of withdrawal such as feeding difficulties, irritability, agitation, and excessive drowsiness.
There are no controlled data of this drug in human pregnancy, but there are some available data for amphetamines in pregnant women. Two case control studies of over a thousand patients exposed to amphetamines at different gestational ages did not show an increase in congenital abnormalities. Additionally, animal studies have revealed no effects on embryofetal morphological development and survival, nor on fertility.
AU TGA pregnancy category B3: Drugs which have been taken by only a limited number of pregnant women and women of childbearing age, without an increase in the frequency of malformation or other direct or indirect harmful effects on the human fetus having been observed. Studies in animals have shown evidence of an increased occurrence of fetal damage, the significance of which is considered uncertain in humans.
US FDA pregnancy category C: Animal reproduction studies have shown an adverse effect on the fetus and there are no adequate and well-controlled studies in humans, but potential benefits may warrant use of the drug in pregnant women despite potential risks.

Drug and Breastfeeding Interactions
Major
Wellbutrin Xl
+ Breastfeeding
The following applies to the ingredients: Bupropion (found in Wellbutrin Xl)
Professional Content
A decision should be made to discontinue nursing or discontinue the drug, taking into account the benefit of breast-feeding to the infant and the importance of the drug to the mother.
-Some experts recommend: Use with caution.
Excreted into human milk: Yes
Comment: Another drug may be preferred, particularly when breastfeeding a newborn or preterm infant.
There is limited information that maternal bupropion at oral doses up to 300 mg daily produces low levels in breastmilk. It is not generally expected to cause adverse effects in breastfed infants; however, there are case reports of possible seizure in partially breastfed 6-month-olds. Alternate drugs that may be considered in place of bupropion include nortriptyline, paroxetine, and sertraline.
One case report has suggested that bupropion accumulates in human breast milk in concentrations much greater than in maternal plasma. At least two metabolites of bupropion are also detectable in human milk. However, in the plasma of one nursing infant whose mother took bupropion, neither bupropion nor its metabolites could be detected.
Data from a lactation study in 10 women showed breastmilk levels of 45.2 mcg/L for bupropion, and 104.6 mcg/mL, 72.1 mcg/mL, and 459 mcg/mL for it metabolites hydroxybupropion, erythrohydroxybupropion, and threohydroxybupropion, respectively. The authors of this study estimated that an exclusively breastfed infant would receive an average of 0.2% of the maternal weight-adjusted dose of bupropion and an average of 2% of the maternal weight-adjusted dosage of bupropion plus metabolites.

Vyvanse
+ Breastfeeding
The following applies to the ingredients: Lisdexamfetamine (found in Vyvanse)
Professional Content
Use should be avoided during breastfeeding.
Excreted into human milk: Yes
Comments:
-This drug is a prodrug of dextroamphetamine. The effect of dextroamphetamine in milk on the neurological development of a breastfed infant has not been well studied.
-Large dosages of this drug might interfere with milk production, especially in women whose lactation is not well established.
-Blood levels of dextroamphetamine in 3 breastfed infants were up to 14% of the maternal plasma level.
-Four breastfed infants whose mothers took an average dose of 18 mg/day of dextroamphetamine had no adverse effects and showed normal progress with weights between the 10th and 75th percentiles.
-In a study of 20 postpartum women, dextroamphetamine reduced serum prolactin by 25% to 32% (7.5 mg IV dose) and 30% to 37% (15 mg IV dose). Another study showed a 20 mg oral dose produced a sustained suppression of serum prolactin by 40%.
