Interactions between your drugs

Major

codeine propiomazine

Applies to: Polyhist NC (codeine / pseudoephedrine / triprolidine) and propiomazine

Using narcotic pain or cough medications together with other medications that also cause central nervous system depression can lead to serious side effects including profound sedation, respiratory distress, coma, and even death. Talk to your doctor if you have any questions or concerns. Your doctor may be able to prescribe alternatives that do not interact, or you may need a dose adjustment or more frequent monitoring to safely use both medications. Do not drink alcohol or self-medicate with these medications without your doctor's approval, and do not exceed the doses or frequency and duration of use prescribed by your doctor. Also, because these medications may cause dizziness, drowsiness, difficulty concentrating, and impairment in judgment, reaction speed and motor coordination, you should avoid driving or operating hazardous machinery until you know how they affect you. 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.

Moderate

codeine triprolidine

Applies to: Polyhist NC (codeine / pseudoephedrine / triprolidine) and Polyhist NC (codeine / pseudoephedrine / triprolidine)

Using codeine together with triprolidine may increase side effects such as dizziness, drowsiness, confusion, and difficulty concentrating. Some people, especially the elderly, may also experience impairment in thinking, judgment, and motor coordination. You should avoid or limit the use of alcohol while being treated with these medications. Also avoid activities requiring mental alertness such as driving or operating hazardous machinery until you know how the medications affect you. Talk to your doctor if you have any questions or concerns. 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.

Moderate

pseudoephedrine propiomazine

Applies to: Polyhist NC (codeine / pseudoephedrine / triprolidine) and propiomazine

Consumer information for this interaction is not currently available.

GENERALLY AVOID: Phenothiazines may antagonize the pharmacologic effects of amphetamine, amphetamine derivatives, and other centrally-acting sympathomimetic agents (i.e., CNS stimulants). Conversely, these agents may diminish the neuroleptic efficacy of phenothiazines. The exact mechanism of interaction is unknown but may involve opposing effects on dopaminergic activity. Several clinical studies have demonstrated the reduction or lack of effect of amphetamines on weight loss in obese psychiatric patients treated with chlorpromazine and other neuroleptic agents. In one of these studies, dextroamphetamine also had no effect on sleep patterns. As for the reverse interaction, it is uncertain whether CNS stimulants actually antagonize the neuroleptic effect of phenothiazines, since CNS stimulants alone have been reported to cause or aggravate preexisting psychotic symptoms. Finally, it is conceivable that, because of their sympathomimetic effects, CNS stimulants may also potentiate the arrhythmogenicity of phenothiazines. A case of fatal ventricular arrhythmia was reported in a patient treated chronically with thioridazine who ingested a single capsule containing phenylpropanolamine 50 mg and chlorpheniramine 4 mg. However, a causal relationship was not established.

MANAGEMENT: Amphetamine, amphetamine derivatives, and other CNS stimulants should generally not be used, particularly for weight reduction, in patients treated with phenothiazines.

Moderate

triprolidine propiomazine

Applies to: Polyhist NC (codeine / pseudoephedrine / triprolidine) and propiomazine

Using triprolidine together with propiomazine may increase side effects such as drowsiness, blurred vision, dry mouth, heat intolerance, flushing, decreased sweating, difficulty urinating, abdominal cramping, constipation, irregular heartbeat, confusion, and memory problems. Side effects may be more likely to occur in the elderly or those with a debilitating condition. You should avoid or limit the use of alcohol while being treated with these medications. Also avoid activities requiring mental alertness such as driving or operating hazardous machinery until you know how the medications affect you. Talk to your doctor if you have any questions or concerns. 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.

Drug and food interactions

Moderate

triprolidine food

Applies to: Polyhist NC (codeine / pseudoephedrine / triprolidine)

Alcohol can increase the nervous system side effects of triprolidine such as dizziness, drowsiness, and difficulty concentrating. Some people may also experience impairment in thinking and judgment. You should avoid or limit the use of alcohol while being treated with triprolidine. Do not use more than the recommended dose of triprolidine, and avoid activities requiring mental alertness such as driving or operating hazardous machinery until you know how the medication affects you. Talk to your doctor or pharmacist if you have any questions or concerns.

Moderate

codeine food

Applies to: Polyhist NC (codeine / pseudoephedrine / triprolidine)

Do not use alcohol or medications that contain alcohol while you are receiving treatment with codeine. This may increase nervous system side effects such as drowsiness, dizziness, lightheadedness, difficulty concentrating, and impairment in thinking and judgment. In severe cases, low blood pressure, respiratory distress, fainting, coma, or even death may occur. With certain long-acting formulations of narcotic pain medication, consumption of alcohol may also cause rapid release of the drug, resulting in high blood levels that may be potentially lethal. Talk to your doctor or pharmacist if you have questions on how to take this or other medications you are prescribed. Do not use more than the recommended dose of codeine, and avoid activities requiring mental alertness such as driving or operating hazardous machinery until you know how the medication affects you. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medication without first talking to your doctor.

Moderate

propiomazine food

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, and 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.

Moderate

pseudoephedrine food

Applies to: Polyhist NC (codeine / pseudoephedrine / triprolidine)

Both pseudoephedrine and caffeine can increase blood pressure and heart rate, and combining them may enhance these effects. Talk to your doctor before using these medications, especially if you have a history of high blood pressure or heart disease. You may need a dose adjustment or more frequent monitoring by your doctor to safely use both medications. Contact your doctor if your condition changes or you experience increased side effects. 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.

Therapeutic duplication warnings

Therapeutic duplication is the use of more than one medicine from the same drug category or therapeutic class to treat the same condition. This can be intentional in cases where drugs with similar actions are used together for demonstrated therapeutic benefit. It can also be unintentional in cases where a patient has been treated by more than one doctor, or had prescriptions filled at more than one pharmacy, and can have potentially adverse consequences.
