Drug interactions
Moderate drug interactions
Moderate:
guanFACINE propiomazine
Applies to: guanfacine and propiomazine
Propiomazine and guanFACINE may have additive effects in lowering your blood pressure.
You may experience headache, dizziness, lightheadedness, fainting, and/or changes in pulse or heart rate.
These side effects are most likely to be seen:
- at the beginning of treatment
- following a dose increase
- 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.
Avoid activities requiring mental alertness such as 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
Major food/lifestyle interactions
Major:
guanFACINE Food/Lifestyle
Applies to: guanfacine
Avoid consuming grapefruit or grapefruit juice during treatment with guanFACINE, as it may increase blood levels and effects of the medication. This may cause blood pressure to fall excessively, especially when you rise from a sitting or lying position. The risk of other side effects such as drowsiness, dizziness, lightheadedness, fainting, headache, palpitations, and heart rate changes may also increase.
Additionally, you should avoid or limit the use of alcohol while being treated with guanFACINE. Combining the medication with alcohol can intensify sedative and blood pressure lowering effects, which may increase the risk of falls and injury.
Avoid driving or operating hazardous machinery until you know how the medication affects you, and use caution when getting up from a sitting or lying position.
If you are using a long-acting or extended-release formulation of the medication, make sure you do not take it with a high-fat meal. Doing so results in increased absorption and elevated blood levels of the medication.
Talk to your doctor or pharmacist if you have any questions or concerns.
Moderate food/lifestyle interactions
Moderate:
propiomazine Alcohol (Ethanol)
Applies to: propiomazine
Ask your doctor before using propiomazine together with ethanol (alcohol).
This can cause:
- uncontrollable movements
- agitation
- seizures
- severe dizziness or fainting
- coma
- very deep sleep
- irregular heartbeats
- high or low body temperature
Use caution when driving, operating machinery, or performing other hazardous activities, these medicaions may cause dizziness or drowsiness. If you experience dizziness or drowsiness, avoid these activities.
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
14 potential interactions Applies to: 12 conditions, including Depression, Hypotension, Peripheral Arterial Disease, Urinary Retention, and Liver Disease.
Cerebrovascular Insufficiency
Moderate:
guanfacine
guanFACINE has a moderate potential interaction with Cerebrovascular Insufficiency.
Central alpha-2 adrenoreceptor agonists reduce sympathetic outflow from the central nervous system, resulting in decreases in heart rate, peripheral and renovascular resistance, and blood pressure. Therapy with these agents should be administered cautiously in patients with hypotension or conditions that may be exacerbated by decreased blood pressure and perfusion, such as coronary insufficiency, peripheral vascular disease (e.g., Raynaud's syndrome), cerebrovascular disease, or recent myocardial infarction.
Depression
Major:
propiomazine
Propiomazine has a major potential interaction with Depression.
A variety of abnormal thinking and behavior changes have been reported to occur in association with the use of most anxiolytics, sedatives and hypnotics. Some of these changes include decreased inhibition, aggressiveness, agitation, and hallucinations. These drugs can cause or exacerbate mental depression and cause suicidal behavior and ideation. Therapy with these drugs should be administered cautiously in patients with a history of depression or other psychiatric disorders. Patients should be monitored for any changes in mood or behavior. It may be prudent to refrain from dispensing large quantities of medication to these patients.
Moderate:
guanfacine
guanFACINE has a moderate potential interaction with Depression.
Central alpha-2 adrenoreceptor agonists may occasionally cause mental depression and should be used cautiously in patients with a history of depression.
Glaucoma/Intraocular Hypertension
Moderate:
propiomazine
Propiomazine has a moderate potential interaction with Glaucoma/Intraocular Hypertension.
Some hypnotic drugs can have an anticholinergic effect and should be used with caution in patients with glaucoma, and trouble urinating due to retention or enlarged prostate.
Heart Block
Moderate:
guanfacine
guanFACINE has a moderate potential interaction with Heart Block.
Central alpha-2 adrenoreceptor agonists reduce sympathetic outflow from the central nervous system. Heart rate is decreased, which may lead to or exacerbate sinus bradycardia and atrioventricular block. Therapy with central alpha-2 adrenoreceptor agonists should be administered cautiously in patients with conduction disturbances such as sinus node dysfunction or AV nodal disease.
Hyperkinetic Syndrome of Childhood
Moderate:
guanfacine
guanFACINE has a moderate potential interaction with Hyperkinetic Syndrome of Childhood.
The safety and effectiveness of guanfacine in children under 12 years of age has not been demonstrated and its use in this age group is not recommended. However, there have been some spontaneous postmarketing reports of mania and aggressive behavioral changes in pediatric patients with attention- deficit hyperactivity disorder (ADHD) that received this drug. All patients had medical or family risks of bipolar disorder, and all of them recovered after treatment discontinuation. Hallucinations have also been reported in pediatric patients receiving guanfacine for the treatment of ADHD.
Hypotension
Moderate:
guanfacine
guanFACINE has a moderate potential interaction with Hypotension.
Central alpha-2 adrenoreceptor agonists reduce sympathetic outflow from the central nervous system, resulting in decreases in heart rate, peripheral and renovascular resistance, and blood pressure. Therapy with these agents should be administered cautiously in patients with hypotension or conditions that may be exacerbated by decreased blood pressure and perfusion, such as coronary insufficiency, peripheral vascular disease (e.g., Raynaud's syndrome), cerebrovascular disease, or recent myocardial infarction.
Ischemic Heart Disease
Moderate:
guanfacine
guanFACINE has a moderate potential interaction with Ischemic Heart Disease.
Central alpha-2 adrenoreceptor agonists reduce sympathetic outflow from the central nervous system, resulting in decreases in heart rate, peripheral and renovascular resistance, and blood pressure. Therapy with these agents should be administered cautiously in patients with hypotension or conditions that may be exacerbated by decreased blood pressure and perfusion, such as coronary insufficiency, peripheral vascular disease (e.g., Raynaud's syndrome), cerebrovascular disease, or recent myocardial infarction.
Liver Disease
Moderate:
guanfacine
guanFACINE has a moderate potential interaction with Liver Disease.
Normally, approximately 50% of a guanfacine dose is eliminated unchanged by the kidney and the rest metabolized by the liver. However, neither the parent drug nor its metabolites accumulate significantly during chronic dosing in patients with severe renal impairment due to increased hepatic metabolism of the drug in these patients. Thus, initial dosage adjustments are generally not necessary in renal impairment. Dosage titration, however, should be made cautiously if hepatic function is also compromised. The pharmacokinetics of guanfacine has not been studied in patients with liver disease. The manufacturer recommends caution when the drug is used in such patients.
Moderate:
propiomazine
Propiomazine has a moderate potential interaction with Liver Disease.
In general, anxiolytics, sedatives and hypnotics are extensively metabolized by the liver. Their plasma clearance may be decreased and their half-life prolonged in patients with impaired hepatic function. Therapy with these drugs should be administered cautiously in patients with liver disease (some are not recommended in severe liver impairment), and the dosage should be adjusted accordingly. Laboratory testing is recommended prior and during treatment.
Peripheral Arterial Disease
Moderate:
guanfacine
guanFACINE has a moderate potential interaction with Peripheral Arterial Disease.
Central alpha-2 adrenoreceptor agonists reduce sympathetic outflow from the central nervous system, resulting in decreases in heart rate, peripheral and renovascular resistance, and blood pressure. Therapy with these agents should be administered cautiously in patients with hypotension or conditions that may be exacerbated by decreased blood pressure and perfusion, such as coronary insufficiency, peripheral vascular disease (e.g., Raynaud's syndrome), cerebrovascular disease, or recent myocardial infarction.
Renal Dysfunction
Moderate:
guanfacine
guanFACINE has a moderate potential interaction with Renal Dysfunction.
