Forfivo XL Side Effects Center
Medical Editor: Charles Patrick Davis, MD, PhD
Forfivo XL is an aminoketone drug indicated for the treatment of major depressive disorder. Forfivo is available as a generic termed bupropion and other names. The most common reported side effects are dry mouth, nausea, insomnia, dizziness, pharyngitis, abdominal pain, agitation, anxiety, tremor, palpitation, sweating, tinnitus, myalgia, anorexia, urinary frequency, and rash. Patients, their families, and their caregivers should be encouraged to be alert to the emergence of anxiety, agitation, panic attacks, insomnia, irritability, hostility, aggressiveness, impulsivity, akathisia (psychomotor restlessness). Consumption of alcohol should be minimized or avoided.
Forfivo XL is supplied as450 mg strength tablets that should be taken once daily without food. The tablet should be swallowed whole and should not be crushed, divided, or chewed. Serious side effects include seizures, suicidal thoughts and behaviors. Patients are advised that Forfivo XL should be discontinued and not restarted if they experience a seizure while on treatment. Although Forfivo XL is not indicated for smoking cessation treatment, it contains the same active ingredient as Zyban which is approved for this use. Patients should be advised to notify their physicians if they become pregnant or intend to become pregnant during therapy. It is not known if Forfivo XL can harm unborn babies. Patients should notify their doctors if they are breastfeeding or plan to breastfeed. It is not known if Forfivo XL passes through breast milk. Forfivo's safety and effectiveness has not been demonstrated in the pediatric population.

Clinical Trials Experience
Commonly Observed Adverse Reactions in Controlled Clinical Trials
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice.
Adverse reactions from Table 5 occurring in at least 5% of patients treated with the sustained-release formulation of bupropion hydrochloride and at a rate at least twice the placebo rate are listed below for the 300- and 400-mg/day dose groups.
FORFIVO XL is bioequivalent to three 150 mg tablets of WELLBUTRIN XL®, which has been demonstrated to have similar bioavailability both to the immediate-release formulation of bupropion and to the sustained-release formulation of bupropion. The information included under this subsection and under subsections 6.2 and 6.3 is based primarily on data from controlled clinical trials with the sustained-release formulation of bupropion hydrochloride.
Adverse Reactions Leading to Discontinuation of Treatment with Bupropion Immediate Release or Bupropion Sustained Release
In placebo-controlled clinical trials, 9% and 11% of patients treated with 300 and 400 mg/day, respectively, of the sustained-release formulation of bupropion hydrochloride and 4% of patients treated with placebo discontinued treatment due to adverse reactions. The specific adverse reactions in these trials that led to discontinuation in at least 1% of patients treated with either 300 mg/day or 400 mg/day of the sustained-release formulation of bupropion hydrochloride, and at a rate at least twice the placebo rate are listed in Table 4.

|Adverse Reaction||Bupropion HCl 300 mg/day
(n = 376)
|Bupropion HCl 400 mg/day
(n = 114)
(n = 385)
In clinical trials with the immediate-release formulation of bupropion, 10% of patients and volunteers discontinued due to an adverse reaction. Reactions resulting in discontinuation, in addition to those listed above for the sustained-release formulation of bupropion hydrochloride, include vomiting, seizures, and sleep disturbances.
Adverse Reactions Occurring at an Incidence of 1% or More Among Patients Treated With Bupropion Immediate release or Bupropion Sustained Release
Table 5 enumerates adverse reactions that occurred among patients treated with 300 and 400 mg/day of the sustained-release formulation of bupropion hydrochloride and with placebo in controlled trials. Reactions that occurred in either the 300- or 400-mg/day group at an incidence of 1% or more and were more frequent than in the placebo group are included. Reported adverse reactions were classified using a COSTART-based Dictionary.
Accurate estimates of the incidence of adverse reactions associated with the use of any drug are difficult to obtain. Estimates are influenced by drug dose, detection technique, setting, physician judgments, etc. The figures cited cannot be used to predict precisely the incidence of untoward reactions in the course of usual medical practice where patient characteristics and other factors differ from those that prevailed in the clinical trials. These incidence figures also cannot be compared with those obtained from other clinical studies involving related drug products as each group of drug trials is conducted under a different set of conditions.
Finally, it is important to emphasize that the tabulation does not reflect the relative severity and/or clinical importance of the reactions. A better perspective on the serious adverse reactions associated with the use of bupropion is provided in the WARNINGS AND PRECAUTIONS.

|Central nervous system stimulation||2%||1%||1%|

|* Adverse reactions that occurred in at least
1% of patients treated with either 300 or 400 mg/day of the sustained-release
formulation of bupropion hydrochloride, but equally or more frequently
in the placebo group, were: abnormal dreams, accidental injury, acne,
appetite increased, back pain, bronchitis, dysmenorrhea, dyspepsia, flatulence,
flu syndrome, hypertension, neck pain, respiratory disorder, rhinitis,
and tooth disorder.

Additional reactions to those listed in Table 5 that occurred at an incidence of at least 1% in controlled clinical trials of the immediate-release formulation of bupropion hydrochloride (300 to 600 mg/day) and that were numerically more frequent than placebo were: cardiac arrhythmias (5% vs. 4%), hypertension (4% vs. 2%), hypotension (3% vs. 2%), tachycardia (11% vs. 9%), appetite increase (4% vs. 2%), dyspepsia (3% vs. 2%), menstrual complaints (5% vs. 1%), akathisia (2% vs. 1%), impaired sleep quality (4% vs. 2%), sensory disturbance (4% vs. 3%), confusion (8% vs. 5%), decreased libido (3% vs. 2%), hostility (6% vs. 4%), auditory disturbance (5% vs. 3%), and gustatory disturbance (3% vs. 1%).
Other adverse reactions occurring < 1% in clinical trials
Chills, facial edema, postural hypotension, stroke, syncope, bruxism, gastric reflux, gingivitis, glossitis, increased salivation, mouth ulcers, stomatitis, edema of tongue, ecchymosis, edema, abnormal coordination, decreased libido, depersonalization, emotional lability, hyperkinesia, hypertonia, hypesthesia, ataxia, and derealization, bronchospasm, accommodation abnormality, dry eye, impotence, and prostate disorder.
The following adverse reactions have been identified during post-approval use of Bupropion hydrochloride. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
Only those adverse reactions not previously listed for bupropion are included. The extent to which these reactions may be associated with FORFIVO XL is unknown.
Metabolic and Nutritional-glycosuria.
Musculoskeletal-muscle rigidity/fever/rhabdomyolysis and muscle weakness.
Nervous System-abnormal electroencephalogram (EEG), aggression, akinesia, aphasia, coma, delirium,dysarthria, dyskinesia, dystonia, extrapyramidal syndrome, hypokinesia, increased libido, neuralgia, neuropathy, and unmasking tardive dyskinesia.
