Other

Some of the adverse reactions listed below may not have been reported with protriptyline (the active ingredient contained in Vivactil) However, these adverse effects have been reported with other tricyclic antidepressants which are pharmacologically similar to protriptyline.[Ref]

Cardiovascular

Cardiovascular side effects include myocardial infarction, stroke, heart block, arrhythmias, hypotension (particularly orthostatic hypotension), hypertension, tachycardia, and palpitation.[Ref]

Psychiatric

Psychiatric side effects include confusional states (particularly in the elderly) with hallucinations, disorientation, delusions, anxiety, restlessness, agitation, hypomania, exacerbation of psychosis, insomnia, panic, and nightmares.[Ref]

Nervous system

Nervous system side effects include seizures, incoordination, ataxia, tremors, peripheral neuropathy, numbness, tingling and paresthesias of extremities, sleep abnormalities, extrapyramidal symptoms, drowsiness, dizziness, weakness and fatigue, headache, syndrome of inappropriate antidiuretic hormone secretion, tinnitus, and alteration in EEG patterns.[Ref]

Nearly all selective serotonin reuptake inhibitors, mixed serotonin/norepinephrine reuptake inhibitors, and tricyclic antidepressants cause sleep abnormalities to some extent. These antidepressants have marked dose-dependent effects on rapid eye movement (REM) sleep, causing reductions in the overall amount of REM sleep over the night and delays the first entry into REM sleep (increased REM sleep onset latency (ROL)), both in healthy subjects and depressed patients. The antidepressants that increase serotonin function appear to have the greatest effect on REM sleep. The reduction in REM sleep is greatest early in treatment, but gradually returns towards baseline during long-term therapy; however, ROL remains long. Following discontinuation of therapy the amount of REM sleep tends to rebound. Some of these drugs (i.e., bupropion, mirtazapine, nefazodone, trazodone, trimipramine) appear to have a modest or minimal effect on REM sleep.[Ref]
