In studies, when started in the fall, Wellbutrin XL was found effective in preventing recurrent symptoms related to SAD. Though symptoms can (and often do) resolve on their own in the spring and summer months, people who have an intense wellbutrin uses, dosage, side effects experience might benefit from a drug like Wellbutrin. You are encouraged to report negative side effects of prescription drugs to the FDA. These include people who have (or have a family history of) bipolar illness (also called manic-depressive illness) or suicidal thoughts or actions.
In many people, these symptoms went away after stopping WELLBUTRIN, but in some people symptoms continued after stopping WELLBUTRIN. It is important for you to follow-up with your healthcare provider until your symptoms go away. Although citalopram is not primarily metabolized by CYP2D6, in one trial bupropion increased the Cmax and AUC of citalopram by 30% and 40%, respectively. Following oral administration of 200 mg of 14C-bupropion in humans, 87% and 10% of the radioactive dose were recovered in the urine and feces, respectively.
You’ll likely take the drug from fall to early spring and stop taking it during the summer. This is because symptoms of SAD generally occur during winter and diminish in spring. The recommended starting dose of Wellbutrin XL for SAD is 150 mg. After 7 days, your doctor may recommend increasing your daily dose to 300 mg.
If you have been prescribed Wellbutrin, here are some side effects to watch for. One factor that makes Wellbutrin especially unique among antidepressants is that it doesn't tend to affect sexual function or reduce libido, and may even increase it. In fact, Wellbutrin is often prescribed along with other antidepressants to help counter their sexual side effects, like loss of desire. Do not stop taking this medicine without checking first with your doctor. Your doctor may want you to gradually reduce the amount you are taking before stopping it completely. Drinking alcoholic beverages should be limited or avoided, if possible, with bupropion.

Multiple oral doses of bupropion had no statistically significant effects on the single-dose pharmacokinetics of lamotrigine in 12 healthy volunteers. In another healthy volunteer trial, lopinavir 400 mg/ritonavir 100 mg twice daily decreased bupropion AUC and Cmax by 57%. The AUC and Cmax of hydroxybupropion were decreased by 50% and 31%, respectively. The exact mechanism of the antidepressant action of bupropion is not known but is presumed to be related to noradrenergic and/or dopaminergic mechanisms. Bupropion is a relatively weak inhibitor of the neuronal reuptake of norepinephrine and dopamine and does not inhibit the reuptake of serotonin.
These trials did not show an increase in the risk of suicidal thoughts and behavior with antidepressant use in subjects over age 24; there was a reduction in risk with antidepressant use in subjects aged 65 and older see WARNINGS AND PRECAUTIONS. If you happen to miss a dose of bupropion, take it as soon as you remember. Any remaining doses for the day should be taken at least six hours apart.
There were suicides in the adult trials, but the number was not sufficient to reach any conclusion about drug effect on suicide. At least 14 days should elapse between discontinuation of an MAOI intended to treat depression and initiation of therapy with WELLBUTRIN. Conversely, at least 14 days should be allowed after stopping WELLBUTRIN before starting an MAOI antidepressant see CONTRAINDICATIONS, DRUG INTERACTIONS. The most common Wellbutrin side effects tend to be the least serious and are likely to be temporary.
The effects of cigarette smoking on the pharmacokinetics of bupropion were studied in 34 healthy male and female volunteers; 17 were chronic cigarette smokers and 17 were nonsmokers. Following oral administration of a single 150-mg dose of bupropion, there were no statistically significant differences in Cmax, half-life, Tmax, AUC, or clearance of bupropion or its active metabolites between smokers and nonsmokers. The second trial demonstrated no statistically significant differences in the pharmacokinetics of bupropion and its active metabolites in 9 subjects with mild-to-moderate hepatic cirrhosis compared with 8 healthy volunteers. However, more variability was observed in some of the pharmacokinetic parameters for bupropion (AUC, Cmax, and Tmax) and its active metabolites (t½) in subjects with mild-to-moderate hepatic cirrhosis. In subjects with severe hepatic cirrhosis, significant alterations in the pharmacokinetics of bupropion and its metabolites were seen (Table 3).
Call your healthcare provider right away if you have any of the following symptoms of a manic episode. These side effects may vary depending on the condition being treated and what form of bupropion you are taking. Tell your healthcare provider if you have any of these side effects that bother you. Off-label uses (non-FDA approved) for bupropion include posttraumatic stress disorder (PTSD), anxiety, attention deficit hyperactivity disorder (ADHD), social phobia, and nerve pain (neuropathic pain). Be sure to tell your doctor about any kidney or liver problems you have and medications you take before starting Wellbutrin treatment. Other medical conditions, such as kidney or liver problems, can also affect your Wellbutrin dosage.
Bupropion is extensively metabolized in the liver to active metabolites, which are further metabolized and excreted by the kidneys. The risk of adverse reactions may be greater in patients with impaired renal function. Bupropion (brand names include Wellbutrin, Wellbutrin SR, Wellbutrin XL, and others) is a medication used to treat major depressive disorder (MDD)15. It works differently from many other antidepressants because it affects norepinephrine and dopamine instead of serotonin1.
Dosage increase of WELLBUTRIN may be necessary when coadministered with ritonavir, lopinavir, or efavirenz see CLINICAL PHARMACOLOGY but should not exceed the maximum recommended dose. Concomitant treatment with these drugs can increase bupropion exposure but decrease hydroxybupropion exposure. Based on clinical response, dosage adjustment of WELLBUTRIN may be necessary when coadministered with CYP2B6 inhibitors (e.g., ticlopidine or clopidogrel) see CLINICAL PHARMACOLOGY. Antidepressants increased the risk of suicidal thoughts and behavior in children, adolescents, and young adults in short-term trials.
