Alcoholism
Major:
amitriptyline
Amitriptyline 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:
amitriptyline
Amitriptyline 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.
Allergies
Major:
Azo Gantanol
The sulfamethoxazole in Azo Gantanol has a major potential interaction with Allergies.
The use of sulfonamides is associated with large increases in the risk of Stevens-Johnson syndrome, toxic epidermal necrolysis and other serious dermatologic reactions, although these phenomena are rare as a whole. Hepatitis, pneumonitis, and interstitial nephritis have also occurred in association with sulfonamide hypersensitivity. Therapy with sulfonamides should be administered cautiously in patients with severe allergies, bronchial asthma or AIDS, since these patients may be at increased risk for potentially severe hypersensitivity reactions. Patients should be instructed to promptly report signs and symptoms that may precede the onset of cutaneous manifestations of the Stevens-Johnson syndrome, such as high fever, severe headache, stomatitis, conjunctivitis, rhinitis, urethritis, and balanitis. Sulfonamide therapy should be stopped at once if a rash develops.
Arrhythmia
Major:
amitriptyline
Amitriptyline 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.
Asthma
Major:
Azo Gantanol
The sulfamethoxazole in Azo Gantanol has a major potential interaction with Asthma.
The use of sulfonamides is associated with large increases in the risk of Stevens-Johnson syndrome, toxic epidermal necrolysis and other serious dermatologic reactions, although these phenomena are rare as a whole.

Hypersensitivity hepatitis has also been reported. Therapy with phenazopyridine should be administered cautiously in patients with impaired hepatic function.
Major:
Azo Gantanol
The sulfamethoxazole in Azo Gantanol has a major potential interaction with Liver Disease.
Hepatotoxicity, including jaundice, diffuse hepatocellular necrosis, hypersensitivity hepatitis and hepatic failure, has rarely been reported in patients receiving sulfonamides. In addition, sulfonamides are partially metabolized by the liver and may accumulate in patients with hepatic impairment. Therapy with sulfonamides should be administered cautiously in patients with liver disease.
Moderate:
amitriptyline
Amitriptyline has a moderate potential interaction with Liver Disease.
In general, tricyclic antidepressants should be used with caution in patients with liver or renal disease, as these drugs are metabolized and excreted through the liver and kidneys. Dose selection, especially in the elderly patients that might have liver or renal dysfunction, should usually be limited to the smallest effective total daily dose. Some tricyclic antidepressants such as clomipramine and nortriptyline have occasionally been associated with elevations in SGOT (AST) and SGPT (ALT), and other hepatic adverse events such as jaundice. Although serious liver injury has only been reported rarely, therapy with these drugs should be administered cautiously in patients with preexisting liver disease and periodic monitoring of liver enzyme levels is recommended.
Moderate:

Amitriptyline has a moderate potential interaction with Liver Disease.
Tricyclic and tetracyclic antidepressants (TCAs) are known to undergo metabolism in the liver. Some of the metabolites, such as those of imipramine, clomipramine and desipramine, may be pharmacologically active. Many of the metabolites are also excreted by the kidney. There are very limited data concerning the use of TCAs in patients with renal and/or liver disease. Therapy with TCAs should be administered cautiously in patients with significantly impaired renal or hepatic function. Dosage adjustments may be necessary.
Mania
Moderate:
amitriptyline
Amitriptyline has a moderate potential interaction with Mania.
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.
Neutropenia
Moderate:
amitriptyline
Amitriptyline has a moderate potential interaction with Neutropenia.
The use of some tricyclic antidepressants has been associated with neutropenia (ANC < 500/mm3) and agranulocytosis (ANC < 500/mm3). Leukocyte and differential blood counts should be performed in patients that develop fever and sore throat during treatment. Therapy should be discontinued if there is evidence of pathologic neutrophil depression.
Noninfectious Colitis
Major:
Azo Gantanol
The sulfamethoxazole in Azo Gantanol has a major potential interaction with Noninfectious Colitis.
Clostridioides difficile-associated diarrhea (CDAD), formerly pseudomembranous colitis, has been reported with almost all antibacterial drugs and may range from mild diarrhea to fatal colitis. The most common culprits include clindamycin and lincomycin. Antibacterial therapy alters the normal flora of the colon, leading to overgrowth of C difficile, whose toxins A and B contribute to CDAD development. Morbidity and mortality are increased with hypertoxin-producing strains of C difficile; these infections can be resistant to antimicrobial therapy and may require colectomy. CDAD must be considered in all patients who present with diarrhea after antibacterial use. Since CDAD has been reported to occur more than 2 months after antibacterial use, careful medical history is necessary. Therapy with broad-spectrum antibacterials and other agents with significant antibacterial activity should be administered cautiously in patients with history of gastrointestinal disease, particularly colitis; pseudomembranous colitis (generally characterized by severe, persistent diarrhea and severe abdominal cramps, and sometimes associated with the passage of blood and mucus), if it occurs, may be more severe in these patients and may be associated with flares in underlying disease activity. Antibacterial drugs not directed against C difficile may need to be stopped if CDAD is suspected or confirmed. Appropriate fluid and electrolyte management, protein supplementation, antibacterial treatment of C difficile, and surgical evaluation should be started as clinically indicated.
Pheochromocytoma
Major:
amitriptyline
Amitriptyline has a major potential interaction with Pheochromocytoma.
Tricyclic and tetracyclic antidepressants (TCAs) may potentiate the effects of circulating catecholamines. Enhanced sympathetic activity can provoke hypertensive crises in patients with pheochromocytoma or other tumors of the adrenal medulla, such as some neuroblastomas. Therapy with TCAs should be administered cautiously in patients with these tumors.
Porphyria
Major:
Azo Gantanol
The sulfamethoxazole in Azo Gantanol has a major potential interaction with Porphyria.
The use of sulfonamides is contraindicated in patients with porphyria, since these drugs can precipitate an acute attack.
Renal Dysfunction
Major:
Azo Gantanol
The phenazopyridine in Azo Gantanol has a major potential interaction with Renal Dysfunction.
The use of phenazopyridine is contraindicated in patients with impaired renal function. Phenazopyridine is primarily eliminated unchanged by the kidney and may accumulate to toxic levels during prolonged administration in such patients. Reported cases of toxicity due to overdosage have resulted in acute renal failure and methemoglobinemia. Likewise, administration of phenazopyridine to patients with preexisting renal failure has led to methemoglobinemia and hemolytic anemia. Phenazopyridine toxicity may be associated with a yellowish tinge of the skin or sclera.
Major:
Azo Gantanol
The sulfamethoxazole in Azo Gantanol has a major potential interaction with Renal Dysfunction.
Sulfonamides and their metabolites are eliminated by the kidney. Patients with renal impairment may be at greater risk for adverse effects from sulfonamides due to decreased drug clearance. Dosage adjustments may be necessary and modifications should be based on the degree of renal impairment and severity of infection. Additionally, sulfonamides may cause renal toxicity secondary to crystalluria, including uro- and nephrolithiasis, nephritis, toxic nephrosis, hematuria, proteinuria, and elevated BUN and creatinine. Hydration (8 oz. glass of water with each dose and throughout the day) and adequate urinary output (> 1.5 L/day) should be maintained during sulfonamide administration. Renal function tests and urinalysis should be performed weekly or as often as indicated by the patient's status. Rarely, alkalinization of the urine is necessary.

Although serious liver injury has only been reported rarely, therapy with these drugs should be administered cautiously in patients with preexisting liver disease and periodic monitoring of liver enzyme levels is recommended.
Schizophrenia
Moderate:
amitriptyline
Amitriptyline has a moderate potential interaction with Schizophrenia.
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:
amitriptyline
Amitriptyline has a moderate potential interaction with Schizophrenia.
Some tricyclic antidepressants have shown to cause activation or exacerbation of psychosis in schizophrenic patients. A dosage reduction might be required.
Tardive Dyskinesia
Moderate:
amitriptyline
Amitriptyline has a moderate potential interaction with Tardive Dyskinesia.
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. As with other drugs that possess anticholinergic activity, TCAs may aggravate tardive dyskinesia or induce previously suppressed symptoms. Patients with tardive dyskinesia requiring therapy with TCAs should be monitored for exacerbation of the condition.
Urinary Retention
Major:
amitriptyline
Amitriptyline 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.
Moderate:
amitriptyline
Amitriptyline 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.
Moderate:
Azo Gantanol
The sulfamethoxazole in Azo Gantanol has a moderate potential interaction with Urinary Retention.
Sulfonamides are excreted and concentrated in the urine. Therapy with sulfonamides should be administered cautiously in patients with urinary obstruction or retention, since excessive drug accumulation may occur. These patients may also be at increased risk for sulfonamide crystalluria, which may be associated with renal toxicity such as uro- and nephrolithiasis, nephritis, toxic nephrosis, hematuria, proteinuria, and elevated BUN and creatinine. A urinary output of at least 1.5 L/day should be maintained during sulfonamide administration. Renal function tests and urinalysis should be performed weekly, especially during prolonged therapy (> 2 weeks).
Vomiting
Moderate:
Azo Gantanol
The sulfamethoxazole in Azo Gantanol has a moderate potential interaction with Vomiting.
Crystalluria can occur during sulfonamide therapy due to precipitation of the sulfonamide and/or its N4-acetyl metabolite in the urinary tract. Renal toxicity such as uro- and nephrolithiasis, nephritis, toxic nephrosis, hematuria, proteinuria, and elevated BUN and creatinine has been reported. Hydration (8 oz. glass of water with each dose and throughout the day) and adequate urinary output (> 1.5 L/day) should be maintained during sulfonamide administration. Patients who are dehydrated (e.g., due to severe diarrhea or vomiting) may be at increased risk for the development of crystalluria and lithiasis and should be encouraged to consume additional amounts of liquid or given intravenous fluid. Renal function tests and urinalysis should be performed weekly during prolonged therapy (> 2 weeks). Rarely, alkalinization of the urine is necessary.
