Drug interactions
Moderate drug interactions
Moderate:
guanadrel brimonidine ophthalmic
Applies to: guanadrel and brimonidine ophthalmic
After using brimonidine ophthalmic, some of the medication may be absorbed into the bloodstream and occasionally produce cardiovascular side effects such as decreases in blood pressure and heart rate. Combining it with guanadrel or other medications that can also have these effects may increase the risk. You may experience headache, dizziness, lightheadedness, fainting, and/or changes in pulse or heart beat. These side effects are most likely to be seen at the beginning of treatment, following a dose increase, or when treatment is restarted after an interruption. Let your doctor know if you develop these symptoms and they do not go away after a few days or they become troublesome. You may need a dose adjustment or more frequent monitoring by your doctor to safely use both medications. Avoid driving or operating hazardous machinery until you know how the medications affect you, and use caution when getting up from a sitting or lying position. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
Food/lifestyle interactions
Moderate food/lifestyle interactions
Moderate:
guanadrel Alcohol (Ethanol)
Applies to: guanadrel
Ethanol and guanadrel may have additive effects in lowering your blood pressure. You may experience headache, dizziness, lightheadedness, fainting, or changes in pulse or heart rate, especially when treatment is started, the dose is changed, or treatment is restarted. Tell your doctor promptly if these symptoms occur and seek urgent medical help if you faint or have severe dizziness. Avoid driving or operating hazardous machinery until you know how the medications affect you, and use caution when getting up from a sitting or lying position. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
Disease interactions
7 potential interactions Applies to: 7 conditions, including Depression, Hypotension, Fluid Retention, Liver Disease, and Cardiovascular Conditions and Disorders.
Cardiovascular Conditions and Disorders
Moderate:
brimonidine ophthalmic
Brimonidine ophthalmic has a moderate potential interaction with Cardiovascular Conditions and Disorders.
Topically applied alpha-2 adrenergic receptor agonists are systemically absorbed, with the potential for producing rare but clinically significant systemic effects. In the central nervous system, alpha adrenergic stimulation causes an inhibition of sympathetic vasomotor centers, resulting in decreased peripheral resistance and bradycardia. While the commercially available agents in the U.S. (apraclonidine and brimonidine) are hydrophilic and do not readily distribute across the ocular-blood barrier into the CNS, prolonged use may increase the risk of systemic effects. There have been occasional reports of bradycardia, chest heaviness or burning, palpitation, reduced blood pressure, and orthostatic hypotension when apraclonidine 1% was administered once or twice a day for 4 weeks to individuals not undergoing laser surgery. Therapy with ophthalmic alpha-2 adrenergic agents should be administered cautiously in patients with severe, uncontrolled cardiovascular disease, including hypertension, coronary or cerebrovascular insufficiency, recent myocardial infarction, chronic renal failure, Raynaud's disease, thromboangiitis obliterans, and a predisposition for orthostatic hypotension.
Cerebrovascular Insufficiency
Moderate:
brimonidine ophthalmic
Brimonidine ophthalmic has a moderate potential interaction with Cerebrovascular Insufficiency.
Topically applied alpha-2 adrenergic receptor agonists are systemically absorbed, with the potential for producing rare but clinically significant systemic effects. In the central nervous system, alpha adrenergic stimulation causes an inhibition of sympathetic vasomotor centers, resulting in decreased peripheral resistance and bradycardia. While the commercially available agents in the U.S. (apraclonidine and brimonidine) are hydrophilic and do not readily distribute across the ocular-blood barrier into the CNS, prolonged use may increase the risk of systemic effects.

Therapy with ophthalmic alpha-2 adrenergic agents should be administered cautiously in patients with severe, uncontrolled cardiovascular disease, including hypertension, coronary or cerebrovascular insufficiency, recent myocardial infarction, chronic renal failure, Raynaud's disease, thromboangiitis obliterans, and a predisposition for orthostatic hypotension.
Depression
Moderate:
brimonidine ophthalmic
Brimonidine ophthalmic has a moderate potential interaction with Depression.
Topically applied alpha-2 adrenergic receptor agonists are systemically absorbed, with the potential for producing rare but clinically significant systemic effects. Depression has infrequently been associated with the ocular use of these drugs due to their inhibiting effect on the sympathetic nervous system. Depressed patients should be monitored for exacerbation of their condition during therapy with ophthalmic alpha-2 adrenergic agents.
Fluid Retention
Moderate:
guanadrel
Guanadrel has a moderate potential interaction with Fluid Retention.
Peripheral- acting antiadrenergic agents can cause peripheral edema. Therapy with peripheral- acting antiadrenergic agents should be administered cautiously in patients adversely affected by sodium and water retention.
Hypotension
Moderate:
brimonidine ophthalmic
Brimonidine ophthalmic has a moderate potential interaction with Hypotension.
Topically applied alpha-2 adrenergic receptor agonists are systemically absorbed, with the potential for producing rare but clinically significant systemic effects. In the central nervous system, alpha adrenergic stimulation causes an inhibition of sympathetic vasomotor centers, resulting in decreased peripheral resistance and bradycardia. While the commercially available agents in the U.S. (apraclonidine and brimonidine) are hydrophilic and do not readily distribute across the ocular-blood barrier into the CNS, prolonged use may increase the risk of systemic effects. There have been occasional reports of bradycardia, chest heaviness or burning, palpitation, reduced blood pressure, and orthostatic hypotension when apraclonidine 1% was administered once or twice a day for 4 weeks to individuals not undergoing laser surgery. Therapy with ophthalmic alpha-2 adrenergic agents should be administered cautiously in patients with severe, uncontrolled cardiovascular disease, including hypertension, coronary or cerebrovascular insufficiency, recent myocardial infarction, chronic renal failure, Raynaud's disease, thromboangiitis obliterans, and a predisposition for orthostatic hypotension.
Liver Disease
Moderate:
brimonidine ophthalmic
Brimonidine ophthalmic has a moderate potential interaction with Liver Disease.
Topically applied alpha-2 adrenergic receptor agonists are systemically absorbed, with the potential for producing rare but clinically significant systemic effects. There are limited data concerning the pharmacokinetic disposition or the clinical use of these drugs in patients with renal and/or liver disease. Therapy with ophthalmic alpha-2 adrenergic agents should be administered cautiously in patients with significantly impaired renal or hepatic function.
Renal Dysfunction
Moderate:
brimonidine ophthalmic
Brimonidine ophthalmic has a moderate potential interaction with Renal Dysfunction.
Topically applied alpha-2 adrenergic receptor agonists are systemically absorbed, with the potential for producing rare but clinically significant systemic effects. There are limited data concerning the pharmacokinetic disposition or the clinical use of these drugs in patients with renal and/or liver disease. Therapy with ophthalmic alpha-2 adrenergic agents should be administered cautiously in patients with significantly impaired renal or hepatic function.
