Interactions between your drugs
reserpine hydroflumethiazide
Applies to: hydroflumethiazide / reserpine and hydroflumethiazide / 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.

reserpine phenylephrine
Applies to: hydroflumethiazide / reserpine and Alka-Seltzer Plus Cold Formula Orange Zest Effervescent Tablets (aspirin / chlorpheniramine / phenylephrine)
MONITOR: Sympathomimetic amines may decrease the hypotensive effect of postganglionic adrenergic blocking agents, while the latter may potentiate the pharmacologic effects of direct-acting sympathomimetic amines (e.g., dobutamine, epinephrine, methoxamine, norepinephrine) but inhibit those that are primarily indirect-acting (e.g., mephentermine). Postganglionic adrenergic blocking agents such as guanadrel, guanethidine, and rauwolfia alkaloids work by depleting catecholamine stores from adrenergic nerve endings. Therefore, they may sensitize adrenergic receptors to direct-acting sympathomimetics, but blunt the effects of indirect-acting agents whose activity is mediated through the release of catecholamines. Guanethidine and reserpine have been reported to attenuate the pharmacologic effects (mydriasis, pressor response) induced by ephedrine and dopamine, both of which exhibit direct and indirect sympathomimetic activities (i.e., mixed-acting). However, guanethidine intensified the mydriasis produced by phenylephrine, which is also thought to be mixed-acting. Conversely, ephedrine has been shown to partially reverse the hypotensive effect of guanethidine.
MANAGEMENT: Due to their pressor effect, sympathomimetic amines should be used cautiously in patients with hypertension. Alternatives to postganglionic adrenergic blocking agents should be considered if patients are treated with sympathomimetic amines, since effects of the latter may be intensified or diminished depending on whether they are direct- or indirect-acting. Most agents with indirect sympathomimetic activity are mixed-acting, thus it may be difficult to predict how they will be affected by postganglionic adrenergic blocking agents. If the combination is used, blood pressure and heart rate should be monitored.

Drug and food interactions
chlorpheniramine food
Applies to: Alka-Seltzer Plus Cold Formula Orange Zest Effervescent Tablets (aspirin / chlorpheniramine / phenylephrine)
GENERALLY AVOID: Alcohol may potentiate some of the pharmacologic effects of CNS-active agents. Use in combination may result in additive central nervous system depression and/or impairment of judgment, thinking, and psychomotor skills.
MANAGEMENT: Patients receiving CNS-active agents should be warned of this interaction and advised to avoid or limit consumption of alcohol. Ambulatory patients should be counseled to avoid hazardous activities requiring complete mental alertness and motor coordination until they know how these agents affect them, and to notify their physician if they experience excessive or prolonged CNS effects that interfere with their normal activities.

aspirin food
Applies to: Alka-Seltzer Plus Cold Formula Orange Zest Effervescent Tablets (aspirin / chlorpheniramine / phenylephrine)
GENERALLY AVOID: The concurrent use of aspirin or nonsteroidal anti-inflammatory drugs (NSAIDs) and ethanol may lead to gastrointestinal (GI) blood loss. The mechanism may be due to a combined local effect as well as inhibition of prostaglandins leading to decreased integrity of the GI lining.
MANAGEMENT: Patients should be counseled on this potential interaction and advised to refrain from alcohol consumption while taking aspirin or NSAIDs.

reserpine food
Applies to: hydroflumethiazide / 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.

phenylephrine food
Applies to: Alka-Seltzer Plus Cold Formula Orange Zest Effervescent Tablets (aspirin / chlorpheniramine / phenylephrine)
MONITOR: Coadministration of two or more sympathomimetic agents may increase the risk of adverse effects such as nervousness, irritability, and increased heart rate. Central nervous system (CNS) stimulants, particularly amphetamines, can potentiate the adrenergic response to vasopressors and other sympathomimetic agents. Additive increases in blood pressure and heart rate may occur due to enhanced peripheral sympathetic activity.
MANAGEMENT: Caution is advised if two or more sympathomimetic agents are coadministered. Pulse and blood pressure should be closely monitored.

One study has reported that coadministration of caffeine and aspirin lead to a 25% increase in the rate of appearance and 17% increase in maximum concentration of salicylate in the plasma. A significantly higher area under the plasma concentration time curve of salicylate was also reported when both drugs were administered together. The exact mechanism of this interaction has not been specified. Physicians and patients should be aware that coadministration of aspirin and caffeine may lead to higher salicylate levels faster.
