There are 16 disease interactions with HydrALAZINE Plus (hydralazine / hydrochlorothiazide):

Major

Hydralazine (Includes HydrALAZINE Plus) ↔ Bone Marrow Suppression

Severe Potential Hazard, Low plausibility

Applies to: Bone Marrow Depression/Low Blood Counts

Hydralazine may rarely cause blood dyscrasias at recommended dosages. Reduction in hemoglobin, red cell count, agranulocytosis, leukopenia, and purpura have been reported. Therapy with hydralazine should be administered cautiously in patients with these preexisting conditions and if such abnormalities develop during the course of therapy, treatment should be discontinued. Monitoring blood counts should be considered for those patients at higher risk.

Hydralazine (Includes HydrALAZINE Plus) ↔ Lupus Erythematosus

Severe Potential Hazard, High plausibility

Applies to: Lupus Erythematosus

The use of hydralazine has been associated with the development of lupus erythematosus and lupus-like syndromes, as well as exacerbation of the disease. Hydralazine therapy should be withdrawn in patients experiencing worsening of preexisting lupus. Monitoring complete blood counts, and antinuclear antibody titers before and during prolonged therapy is recommended.

Thiazides (Includes HydrALAZINE Plus) ↔ Electrolyte Losses

Severe Potential Hazard, High plausibility

Applies to: Hypokalemia, Diarrhea, Electrolyte Abnormalities, Hyperaldosteronism, Hyponatremia, Magnesium Imbalance, Malnourished, Vomiting, Ventricular Arrhythmia, Dehydration

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.

Thiazides (Includes HydrALAZINE Plus) ↔ Liver Disease

Severe Potential Hazard, High plausibility

Applies to: Liver Disease

Patients with severe liver disease or cirrhosis are very susceptible to thiazide-induced hypokalemic hypochloremic alkalosis. Blood ammonia concentrations may be further increased in patients with previously elevated concentrations. Hepatic encephalopathy and death have occurred secondary to the electrolyte alterations accompanying diuretic use. Therapy with thiazide diuretics should be administered cautiously in patients with impaired hepatic function or progressive liver disease, and discontinued promptly if signs of impending hepatic coma appear (e.g., tremors, confusion, and increased jaundice).

Thiazides (Includes HydrALAZINE Plus) ↔ Lupus Erythematosus

Severe Potential Hazard, Moderate plausibility

Applies to: Lupus Erythematosus

The use of thiazide diuretics has been reported to possibly exacerbate or activate systemic lupus erythematosus. Reported cases have generally been associated with chlorothiazide and hydrochlorothiazide. Therapy with thiazide diuretics should be administered cautiously in patients with a history or risk of SLE.

Thiazides (Includes HydrALAZINE Plus) ↔ Renal Function Disorders

Severe Potential Hazard, High plausibility

Applies to: Renal Dysfunction

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.

Hydralazine (Includes HydrALAZINE Plus) ↔ Renal Dysfunction

Moderate Potential Hazard, Moderate plausibility

Applies to: Glomerulonephritis, Renal Dysfunction

The use of hydralazine has been associated with the development of glomerulonephritis. Hydralazine should be used with caution in patients with advanced renal damage and these patients may required a lower dose. Renal function should be monitored and supported as required.

Moderate

Thiazides (Includes HydrALAZINE Plus) ↔ Asthma

Moderate Potential Hazard, Moderate plausibility

Applies to: Asthma

Thiazide diuretics should be used with caution in patients with history of bronchial asthma as sensitivity reactions may occur.

Moderate

Thiazides (Includes HydrALAZINE Plus) ↔ Diabetes

Moderate Potential Hazard, Moderate plausibility

Applies to: Diabetes Mellitus, Abnormal Glucose Tolerance

Thiazide diuretics may cause hyperglycemia and glycosuria in patients with diabetes. They may also precipitate diabetes in prediabetic patients. These effects are usually reversible following discontinuation of the drugs. Therapy with thiazide diuretics should be administered cautiously in patients with diabetes mellitus, glucose intolerance, or a predisposition to hyperglycemia. Patients with diabetes mellitus should be monitored more closely during thiazide therapy, and their antidiabetic regimen adjusted accordingly.

Thiazides (Includes HydrALAZINE Plus) ↔ Hyperlipidemia

Moderate Potential Hazard, Moderate plausibility

Applies to: Hyperlipidemia

Thiazide diuretics may increase serum triglyceride and cholesterol levels, primarily LDL and VLDL. Whether these effects are dose-related and sustained during chronic therapy are unknown. Patients with preexisting hyperlipidemia may require closer monitoring during thiazide therapy, and adjustments made accordingly in their lipid-lowering regimen

Thiazides (Includes HydrALAZINE Plus) ↔ Hyperparathyroidism

Moderate Potential Hazard, Moderate plausibility

Applies to: Hyperparathyroidism

Urinary calcium excretion is decreased by thiazide diuretics during chronic administration. Pathologic changes in the parathyroid gland with hypercalcemia and hypophosphatemia have been reported during prolonged therapy. However, the common complications of hyperparathyroidism such as renal lithiasis, bone resorption, and peptic ulceration have not been seen. Clinicians should be cognizant of these effects when prescribing or administering thiazide therapy to patients with hyperparathyroidism. These drugs should be discontinued before carrying out tests for parathyroid function.

Thiazides (Includes HydrALAZINE Plus) ↔ Hyperuricemia

Moderate Potential Hazard, High plausibility

Applies to: Gout

Thiazide diuretics decrease the rate of uric acid excretion. Hyperuricemia occurs frequently but is usually asymptomatic and rarely leads to clinical gout except in patients with a history of gout or chronic renal failure. Therapy with thiazide diuretics should be administered cautiously in such patients.

Thiazides (Includes HydrALAZINE Plus) ↔ Thyroid Function Tests

Moderate Potential Hazard, Moderate plausibility
