The correct answer and Explanation is:
For a client taking venlafaxine (Effexor), the nurse should include the following instructions:
A. Change positions slowly
B. Avoid alcohol
D. Do not crush or chew extended-release tablets
Explanation:
A. Change positions slowly:
Venlafaxine, an antidepressant in the serotonin-norepinephrine reuptake inhibitor (SNRI) class, can cause orthostatic hypotension (a drop in blood pressure when standing up), leading to dizziness or fainting. Advising the client to change positions slowly helps mitigate this risk, ensuring they transition smoothly from lying or sitting to standing.
B. Avoid alcohol:
Alcohol can enhance the sedative effects of venlafaxine and may also increase the risk of adverse effects such as drowsiness, dizziness, and impaired motor skills. Additionally, both alcohol and venlafaxine can impact mood, potentially worsening depressive symptoms. Therefore, it is advisable to avoid alcohol while on this medication.
D. Do not crush or chew extended-release tablets:
Venlafaxine is often prescribed in an extended-release formulation to provide a steady release of medication over time. Crushing or chewing these tablets can disrupt this controlled release mechanism, leading to a rapid release of the drug and potentially causing increased side effects or decreased efficacy. It is important to swallow these tablets whole to maintain the intended therapeutic effect.
Instructions Not Included:
C. Take with food:
Venlafaxine can be taken with or without food. While taking it with food may help reduce gastrointestinal upset for some people, it is not a mandatory instruction and does not significantly alter the medication’s effectiveness.
E. Take medication at bedtime:
Venlafaxine does not specifically need to be taken at bedtime. It can be taken at any time of the day, but taking it consistently at the same time each day helps maintain steady levels in the blood. Some people may experience insomnia as a side effect, in which case taking it in the morning might be preferable, but this varies by individual.
By following these instructions, the client can help manage their condition effectively while minimizing the risk of side effects and ensuring the medication works as intended.
