Drug Interactions between digitoxin and Uni Serp
This report displays the potential drug interactions for the following 2 drugs:
- digitoxin
- Uni Serp (hydralazine/hydrochlorothiazide/reserpine)
Interactions between your drugs
hydrALAZINE hydroCHLOROthiazide
Applies to: Uni Serp (hydralazine / hydrochlorothiazide / reserpine) and Uni Serp (hydralazine / hydrochlorothiazide / reserpine)
MONITOR: Concomitant treatment with other antihypertensive agents or vasodilators, including alpha-adrenoreceptor antagonists, angiotensin converting enzyme (ACE) inhibitors, angiotensin receptor blockers (ARBs), beta-adrenergic blockers, calcium channel blockers, diuretics and nitrates, may potentiate the hypotensive effects of hydralazine and dihydralazine.
MANAGEMENT: Blood pressure and heart rate should be closely monitored when hydralazine or dihydralazine is used with other agents that can induce hypotension.

digitoxin hydroCHLOROthiazide
Applies to: digitoxin and Uni Serp (hydralazine / hydrochlorothiazide / reserpine)
MONITOR: Although diuretics and digitalis glycosides are frequently and appropriately used together, diuretic-induced hypokalemia and hypomagnesemia may predispose patients on digitalis to arrhythmias.
MANAGEMENT: Digoxin, potassium and magnesium levels should be followed closely. Hypokalemia and hypomagnesemia should be treated appropriately. Digitalis dose adjustments may be required. Patients should be advised to notify their physicians if they experience signs of possible digoxin toxicity or electrolyte disturbances, such as weakness, lethargy, muscle pains or cramps, nausea, anorexia, visual disturbances, or irregular heartbeats.

hydrALAZINE reserpine
Applies to: Uni Serp (hydralazine / hydrochlorothiazide / reserpine) and Uni Serp (hydralazine / hydrochlorothiazide / reserpine)

hydroCHLOROthiazide reserpine
Applies to: Uni Serp (hydralazine / hydrochlorothiazide / reserpine) and Uni Serp (hydralazine / hydrochlorothiazide / reserpine)
MONITOR: The hypotensive effects of thiazide diuretics and alpha-adrenergic blockers may be additive. Postural hypotension may occur.
MANAGEMENT: Hemodynamic responses should be monitored during coadministration, especially during the first few weeks of therapy. Patients should be advised to take the alpha-blocker at bedtime and to notify their physician if they experience dizziness or syncope while awake.

Drug and food interactions
hydrALAZINE food
Applies to: Uni Serp (hydralazine / hydrochlorothiazide / reserpine)
MONITOR: Many psychotherapeutic and CNS-active agents (e.g., anxiolytics, sedatives, hypnotics, antidepressants, antipsychotics, opioids, alcohol, muscle relaxants) exhibit hypotensive effects, especially during initiation of therapy and dose escalation. Coadministration with antihypertensives and other hypotensive agents, in particular vasodilators and alpha-blockers, may result in additive effects on blood pressure and orthostasis.
MANAGEMENT: Caution and close monitoring for development of hypotension is advised during coadministration of these agents. Some authorities recommend avoiding alcohol in patients receiving vasodilating antihypertensive drugs. Patients should be advised to avoid rising abruptly from a sitting or recumbent position and to notify their physician if they experience dizziness, lightheadedness, syncope, orthostasis, or tachycardia.
