A nurse is reinforcing teaching with a client who takes diazepam (Valium). Which of the following information should the nurse include?
A.
“A single dose of diazepam is unlikely to cause side effects.”
B.
“Grapefruit juice inactivates this medication.”
C.
“Diazepam can cause drowsiness.”
D.
Avoid foods that contain tyramine”
The correct answer and Explanation is :
The correct answer is:
C. “Diazepam can cause drowsiness.”
Explanation
Diazepam, commonly known as Valium, is a benzodiazepine medication used to treat anxiety, muscle spasms, and seizures. It acts on the central nervous system by enhancing the effects of a neurotransmitter called gamma-aminobutyric acid (GABA), which has a calming effect. Given its mechanism of action, diazepam can indeed cause drowsiness and sedation as side effects. This is a crucial piece of information for patients taking this medication, as it can impact their ability to perform tasks that require full alertness, such as driving or operating machinery.
Option A: “A single dose of diazepam is unlikely to cause side effects.”
This statement is not accurate. Even a single dose of diazepam can cause side effects, including drowsiness, dizziness, and impaired coordination. The extent of side effects can vary from person to person based on their individual response to the medication and dosage.
Option B: “Grapefruit juice inactivates this medication.”
This statement is incorrect. Grapefruit juice does not inactivate diazepam. However, grapefruit juice can affect the metabolism of some other medications by inhibiting the enzyme CYP3A4, which can lead to increased levels of these medications in the blood. Diazepam is primarily metabolized by the liver enzyme CYP2C19, so grapefruit juice does not have a significant impact on diazepam’s effectiveness.
Option D: “Avoid foods that contain tyramine.”
This advice is generally relevant for patients taking monoamine oxidase inhibitors (MAOIs) rather than benzodiazepines like diazepam. Tyramine is an amino acid found in certain foods and can interact with MAOIs, leading to hypertensive crises. Diazepam does not interact with tyramine-containing foods, so this advice is not applicable.
In summary, patients taking diazepam should be informed that it can cause drowsiness, which is an important consideration for their safety and daily functioning.
