Disease interactions
54 potential interactions Applies to: 34 conditions, including Depression, Bipolar Disorder, Heart Attack, Diarrhea, and Arrhythmia.
Alcoholism
Major:
doxepin
Doxepin has a major potential interaction with Alcoholism.
Tricyclic antidepressants (TCAs), can lower the seizure threshold and trigger seizures. These drugs should be used with extreme caution in patients with a history of seizures, or other predisposing factors, such as head trauma, CNS abnormalities, and alcoholism. Daily dose restrictions might apply for specific antidepressants. Physicians are encouraged to get additional dosing recommendations on the manufacturer's prescribing information.
Moderate:
doxepin
Doxepin has a moderate potential interaction with Alcoholism.
Tricyclic antidepressants can enhance the response to alcohol. In patients who may use alcohol excessively, it should be borne in mind that the potentiation may increase the danger inherent in any suicide attempt or overdosage.
Arrhythmia
Major:
doxepin
Doxepin has a major potential interaction with Arrhythmia.
Tricyclic and tetracyclic antidepressants (TCAs) may cause orthostatic hypotension, reflex tachycardia, syncope, and dizziness, particularly during initiation of therapy or rapid escalation of dosage. Imipramine appears to have the greatest propensity to induce these effects, while secondary amines such as nortriptyline may do so less frequently. Tolerance to the hypotensive effects often develops after a few doses to a few weeks. Rarely, collapse and sudden death have occurred secondary to severe hypotension. Other reported adverse cardiovascular effects include tachycardia, arrhythmias, heart block, hypertension, thrombosis, thrombophlebitis, myocardial infarction, strokes, congestive heart failure, and ECG abnormalities such as PR and QT interval prolongation. Therapy with TCAs should be avoided during the acute recovery phase following myocardial infarction, and should be administered only with extreme caution in patients with hyperthyroidism, a history of cardiovascular or cerebrovascular disease, or a predisposition to hypotension. Close monitoring of cardiovascular status, including ECG changes, is recommended at all dosages. Many of the newer antidepressants, including bupropion and the selective serotonin reuptake inhibitors (SSRIs), are considerably less or minimally cardiotoxic and may be appropriate alternatives.
Moderate:
pacritinib
Pacritinib has a moderate potential interaction with Arrhythmia.
Pacritinib can cause a QT prolongation of greater than 500 msec, and patients receiving this drug were more likely to develop a QT prolongation of at least 60 msec from baseline (compared to the control group) in clinical trials. This agent should be avoided in patients with QT intervals greater than 480 msec at baseline, and/or in those who are taking medications known to prolong the QTc interval. Hypokalemia should be corrected before initiating and during therapy with this agent. QT prolongation occurring during treatment should be managed with treatment interruption and electrolyte management. Periodic monitoring of ECGs and electrolytes is recommended in these patients.
Bipolar Disorder
Moderate:
doxepin
Doxepin has a moderate potential interaction with Bipolar Disorder.
A major depressive episode can be the initial presentation of bipolar disorder. Patients with depressive symptoms should be adequately screened to determine if they are at risk for bipolar disorder prior to initiating treatment with a tricyclic antidepressant. This screening should include a detailed psychiatric history, including a family history of suicide, bipolar disorder, and depression. It should be noted that tricyclic antidepressants are not approved for use in treating bipolar depression.
Moderate:
doxepin
Doxepin has a moderate potential interaction with Bipolar Disorder.
Tricyclic antidepressants (TCAs) may aggravate symptoms of psychosis in schizophrenic patients, particularly those with paranoid symptomatology. Depressed patients, usually those with bipolar disorder, may experience a switch from depression to mania or hypomania. These occurrences have also been reported rarely with the tetracyclic antidepressant, maprotiline. Therapy with these agents should be administered cautiously in patients with schizophrenia, bipolar disorder, or a history of mania.
Moderate:
doxepin
Doxepin has a moderate potential interaction with Bipolar Disorder.
A major depressive episode can be the initial presentation of bipolar disorder.

Major:
pacritinib
Pacritinib has a major potential interaction with Cardiovascular Conditions and Disorders.
In a major safety study of a Janus kinase (JAK) inhibitor, tofacitinib, in rheumatoid arthritis patients 50 years and older with at least 1 cardiovascular risk factor, higher rates of all-cause mortality (including sudden cardiovascular death) and major adverse cardiovascular events (MACE) (defined as cardiovascular death, myocardial infarction, and stroke) were observed with the JAK inhibitor when compared with tumor necrosis factor (TNF) blockers. Patients who were current or past smokers had an additional increased risk. Based on a shared mechanism of action, this risk should be considered for other JAK inhibitors, including baricitinib, upadacitinib, ruxolitinib, fedratinib, ritlecitinib, deuruxolitinib, and pacritinib. Consider the benefits and risks for each individual patient prior and during treatment with JAK inhibitors, especially in patients with other cardiovascular risk factors, history of cardiovascular events, and patients who are current or past smokers. Patients should be informed about the symptoms of serious cardiovascular events and what to do if they occur.

Reducing or interrupting pacritinib should be considered in patients with significant diarrhea (despite optimal supportive care).
Gastrointestinal Obstruction
Major:
doxepin
Doxepin has a major potential interaction with Gastrointestinal Obstruction.
Tricyclic and tetracyclic antidepressants (TCAs) have anticholinergic activity, to which elderly patients are particularly sensitive. Tertiary amines such as amitriptyline and trimipramine tend to exhibit greater anticholinergic effects than other agents in the class. Therapy with TCAs should be administered cautiously in patients with preexisting conditions that are likely to be exacerbated by anticholinergic activity, such as urinary retention or obstruction; angle-closure glaucoma, untreated intraocular hypertension, or uncontrolled primary open-angle glaucoma; and gastrointestinal obstructive disorders. In patients with angle-closure glaucoma, even average doses can precipitate an attack. Glaucoma should be treated and under control prior to initiation of therapy with TCAs, and intraocular pressure monitored during therapy.
Glaucoma, Narrow Angle
Moderate:
doxepin

Thrombosis (including deep venous thrombosis, pulmonary embolism, cerebral venous sinus thrombosis, and arterial thrombosis) has occurred in patients treated for inflammatory conditions with Janus kinase (JAK) inhibitors, including baricitinib, tofacitinib, deuruxolitinib and upadacitinib. Many of these adverse events were serious and some resulted in death. Based on a shared mechanism of action, this risk should be considered for other JAK inhibitors, including ruxolitinib, fedratinib, and pacritinib. In general, JAK inhibitors should be avoided in patients who may be at increased risk of thrombosis. Tofacitinib should be used at the lowest effective dose and for the shortest duration needed to achieve/maintain therapeutic response when treating ulcerative colitis. If symptoms of thrombosis occur in any patients receiving JAK inhibitors, treatment should be discontinued and patients should be evaluated promptly and treated appropriately.
Urinary Retention
Major:
doxepin
Doxepin has a major potential interaction with Urinary Retention.
Tricyclic and tetracyclic antidepressants (TCAs) have anticholinergic activity, to which elderly patients are particularly sensitive. Tertiary amines such as amitriptyline and trimipramine tend to exhibit greater anticholinergic effects than other agents in the class. Therapy with TCAs should be administered cautiously in patients with preexisting conditions that are likely to be exacerbated by anticholinergic activity, such as urinary retention or obstruction; angle-closure glaucoma, untreated intraocular hypertension, or uncontrolled primary open-angle glaucoma; and gastrointestinal obstructive disorders. In patients with angle-closure glaucoma, even average doses can precipitate an attack. Glaucoma should be treated and under control prior to initiation of therapy with TCAs, and intraocular pressure monitored during therapy.
Major:
doxepin
Doxepin has a major potential interaction with Urinary Retention.
The use of doxepin is contraindicated in patients with glaucoma, or a tendency to urinary retention. These disorders should be ruled out before starting treatment, especially in elderly patients.
Moderate:
doxepin
Doxepin has a moderate potential interaction with Urinary Retention.
Some hypnotic drugs can have an anticholinergic effect and should be used with caution in patients with glaucoma, and trouble urinating due to retention or enlarged prostate.
Moderate:
doxepin
Doxepin has a moderate potential interaction with Urinary Retention.
Due to their anticholinergic properties, tricyclic antidepressants should be administered with caution in patients with history of urinary retention. Particularly doxepin hydrochloride capsules are contraindicated in patients with tendency to urinary retention.
Ventricular Arrhythmia
Moderate:
pacritinib
Pacritinib has a moderate potential interaction with Ventricular Arrhythmia.
Pacritinib can cause a QT prolongation of greater than 500 msec, and patients receiving this drug were more likely to develop a QT prolongation of at least 60 msec from baseline (compared to the control group) in clinical trials. This agent should be avoided in patients with QT intervals greater than 480 msec at baseline, and/or in those who are taking medications known to prolong the QTc interval. Hypokalemia should be corrected before initiating and during therapy with this agent. QT prolongation occurring during treatment should be managed with treatment interruption and electrolyte management. Periodic monitoring of ECGs and electrolytes is recommended in these patients.

Drug Interaction Classification
| Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit. | |
| Moderately clinically significant. Usually avoid combinations; use it only under special circumstances. | |
| Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan. | |
| No interaction information available. |
