Drug Interactions between Propacet 100 and VP-Precip
This report displays the potential drug interactions for the following 2 drugs:
- Propacet 100 (acetaminophen/propoxyphene)
- VP-Precip (bilberry/evening primrose/flax)
Interactions between your drugs
propoxyphene evening primrose
Applies to: Propacet 100 (acetaminophen / propoxyphene) and VP-Precip (bilberry / evening primrose / flax)
Some clinicians have suggested that evening primrose and borage oil, both of which contain the omega-6 fatty acid gamma linolenic acid (GLA), may lower the seizure threshold and increase the risk of seizures during co-administration with other epileptogenic agents. However, data regarding the effect of gamma linolenic acid on seizure threshold are conflicting and limited.

Drug and food interactions
propoxyphene food
Applies to: Propacet 100 (acetaminophen / propoxyphene)
GENERALLY AVOID: Alcohol may have additive CNS- and/or respiratory-depressant effects with propoxyphene. Misuse of propoxyphene, either alone or in combination with other CNS depressants, has been a major cause of drug-related deaths, particularly in patients with a history of emotional disturbances, suicidal ideation, or alcohol and drug abuse.
MANAGEMENT: The use of alcohol during propoxyphene therapy should be avoided. Patients should be warned not to exceed the recommended dosage of propoxyphene and to avoid activities requiring mental alertness until they know how these agents affect them.

acetaminophen food
Applies to: Propacet 100 (acetaminophen / propoxyphene)
GENERALLY AVOID: Chronic, excessive consumption of alcohol may increase the risk of acetaminophen-induced hepatotoxicity, which has included rare cases of fatal hepatitis and frank hepatic failure requiring liver transplantation. The proposed mechanism is induction of hepatic microsomal enzymes during chronic alcohol use, which may result in accelerated metabolism of acetaminophen and increased production of potentially hepatotoxic metabolites.
MANAGEMENT: In general, chronic alcoholics should avoid regular or excessive use of acetaminophen. Alternative analgesic/antipyretic therapy may be appropriate in patients who consume three or more alcoholic drinks per day. However, if acetaminophen is used, these patients should be cautioned not to exceed the recommended dosage (maximum 4 g/day in adults and children 12 years of age or older).

Drug Interaction Classification
Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit. | |
Moderately clinically significant. Usually avoid combinations; use it only under special circumstances. | |
Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan. | |
