Thiazide diuretics may be ineffective when the glomerular filtration rate is low (GFR < 25 mL/min) because they are not expected to be filtered into the renal tubule, their site of action. In addition, thiazide diuretics decrease the GFR and may precipitate azotemia in renal disease. Cumulative effects may also develop because most of these drugs are excreted unchanged in the urine by glomerular filtration and active tubular secretion. Therapy with thiazide diuretics should be administered cautiously at reduced dosages in patients with renal impairment. If renal function becomes progressively worse, as indicated by rising BUN or serum creatinine levels, an interruption or discontinuation of thiazide therapy should be considered.

Moderate:

Regroton

The reserpine in Regroton has a moderate potential interaction with Renal Dysfunction.

In general, lowering the blood pressure may cause some decrease in renal function. Therefore, rauwolfia alkaloids should be used with caution in patients with renal impairment, since these patients may adjust poorly to the hypotensive effects of these agents.

Seizures

Moderate:

mirtazapine

Mirtazapine has a moderate potential interaction with Seizures.

The use of tricyclic and tetracyclic antidepressants is associated with a risk of seizures. Only one case of seizure was reported with mirtazapine, a newer tetracyclic antidepressant, during premarketing trials involving nearly 2800 patients. However, the drug has not been evaluated in controlled studies of patients with a history of seizures. Therapy with mirtazapine should be administered cautiously in such patients.

Thyroid Disease

Moderate:

Regroton

The chlorthalidone in Regroton has a moderate potential interaction with Thyroid Disease.

Thiazide diuretics may decrease serum PBI (protein-bound iodine) levels without associated thyroid disturbance. Clinicians should be cognizant of this effect when prescribing or administering thiazide therapy to patients with thyroid disorders.

Ventricular Arrhythmia

Major:

Regroton

The chlorthalidone in Regroton has a major potential interaction with Ventricular Arrhythmia.

The use of thiazide diuretics is commonly associated with loss of electrolytes, most significantly potassium but also sodium, chloride, bicarbonate, and magnesium. The loss of other electrolytes such as phosphate, bromide and iodide is usually slight. Potassium and magnesium depletion may lead to cardiac arrhythmias and cardiac arrest. Other electrolyte-related complications include metabolic alkalosis and hyponatremia, which are rarely life-threatening. Therapy with thiazide diuretics should be administered cautiously in patients with or predisposed to fluid and electrolyte depletion, including patients with primary or secondary aldosteronism (may have low potassium levels); those with severe or prolonged diarrhea or vomiting; and those with poor nutritional status. Fluid and electrolyte abnormalities should be corrected prior to initiating therapy, and blood pressure as well as serum electrolyte concentrations monitored periodically and maintained at normal ranges during therapy. Patients should be advised to immediately report signs and symptoms of fluid or electrolyte imbalance, including dry mouth, thirst, weakness, lethargy, drowsiness, restlessness, muscle pains or cramps, muscular fatigue, hypotension, oliguria, tachycardia, arrhythmia, or gastrointestinal disturbances such as nausea and vomiting. Digitalized patients and patients with a history of ventricular arrhythmias should be monitored carefully, since development of hypokalemia may be particularly dangerous in these patients. The risk of hypokalemia may be minimized by slow diuresis, a lower thiazide dosage, potassium supplementation, or combined use with a potassium-sparing diuretic.

Vomiting

Major:

mirtazapine

Mirtazapine has a major potential interaction with Vomiting.

The use of tetracyclic antidepressants (TCAs) has occasionally been associated with significant orthostatic hypotension secondary to the alpha-1 adrenergic blocking effects of these drugs. Therapy with TCAs should be administered cautiously in patients with hypotension or conditions that could be exacerbated by hypotension, such as a history of myocardial infarction, angina, or ischemic stroke. Patients with dehydration (e.g., due to severe diarrhea or vomiting) may be predisposed to hypotension and should also be managed carefully during therapy with TCAs. Blood pressure should be monitored at regular intervals, particularly during dosage escalation or whenever dosage has been altered, and patients should be advised not to rise abruptly from a sitting or recumbent position.

Regroton

The chlorthalidone in Regroton has a major potential interaction with Vomiting.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor 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.
Unknown No interaction information available.
