Interactions between your selected drugs
valproic acid nitazoxanide
Applies to: valproic acid, nitazoxanide
Consumer information for this interaction is not currently available.
MONITOR: Coadministration with nitazoxanide may increase the free plasma concentrations of drugs and/or their active metabolites that are highly bound to plasma proteins. The pharmacologic effects of some drugs may be increased by this interaction. The proposed mechanism is competitive displacement from protein binding sites by tizoxanide, the active metabolite of nitazoxanide that is greater than 99.9% bound to plasma proteins.
MANAGEMENT: Caution is advised when other highly protein-bound drugs are used with nitazoxanide, particularly those with a narrow therapeutic index. Patients should be monitored more closely following the addition or withdrawal of nitazoxanide. When performing therapeutic drug monitoring, total plasma concentrations should be interpreted cautiously due to the possibility of increased free (unbound) drug.
No other interactions were found between your selected drugs.
Note: this does not necessarily mean no interactions exist. Always consult with your doctor or pharmacist.

Interactions between your selected drugs and food
valproic acid food
Applies to: valproic acid
Alcohol can increase the nervous system side effects of valproic acid 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 valproic acid. Do not use more than the recommended dose of valproic acid, 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.
Applies to: nitazoxanide
Food can enhance the levels of nitazoxanide in your body. Nitazoxanide should be taken just after eating food. Do not take it on an empty stomach. This will make it easier for your body to absorb the medication.
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.
The recommended maximum number of medicines in the 'amebicides' category to be taken concurrently is usually one. Your list includes two medicines belonging to the 'amebicides' category:
- metronidazole (active ingredient in Flagyl (metronidazole))
Note: The benefits of taking this combination of medicines may outweigh any risks associated with therapeutic duplication. This information does not take the place of talking to your doctor. Always check with your healthcare provider to determine if any adjustments to your medications are needed.
Drug Interaction Classification
The classifications below are a guideline only. The relevance of a particular drug interaction to a specific patient is difficult to determine using this tool alone given the large number of variables that may apply.
|Major||Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.|
|Moderate||Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.|
|Minor||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.|
Do not stop taking any medications without consulting your healthcare provider.
