Question 27

The use of alcohol is contraindicated for a patient taking oral metronidazole.

Metronidazole is an antibiotic that can cause a severe reaction when taken with alcohol, leading to symptoms such as flushing, nausea, and vomiting. Therefore, it is crucial for patients on this medication to avoid alcohol consumption.

A) metronidazole.

This option is correct because metronidazole is known to interact negatively with alcohol, leading to disulfiram-like reactions. Patients are advised to refrain from alcohol during treatment and for a period after completing the course of the medication to prevent these adverse effects.

B) tetracycline.

Tetracycline does not have a known contraindication with alcohol. While excessive alcohol consumption can affect overall health and the efficacy of various medications, tetracycline does not specifically warn against alcohol use.

C) albuterol.

Albuterol is a bronchodilator used primarily for asthma and does not have a contraindication with alcohol. Although alcohol may impact respiratory function indirectly, it does not pose a direct interaction with albuterol.

D) prednisone.

Prednisone, a corticosteroid, does not have a direct contraindication with alcohol. However, alcohol can exacerbate side effects associated with long-term steroid use, such as increased risk of gastrointestinal issues, but it is not specifically contraindicated with this medication.

Conclusion

In summary, metronidazole is the only medication listed that has a clear and significant contraindication with alcohol, making it essential for patients to avoid alcohol during treatment. Other options, such as tetracycline, albuterol, and prednisone, do not present the same risk, highlighting the importance of understanding drug interactions in patient care.
