Just as Kendall is experiencing relief from painful muscle spasms with methocarbamol, her spring allergies hit full force and she cannot stop sneezing. Should this be of additional concern?
Yes, because the effects of muscle relaxants can be potentiated by antihistamines.
No, not if she takes both medications at least 30 minutes apart.
Possibly, but only if she takes way too much of the antihistamines.
No, because over-the-counter antihistamines are very safe.
Answer: Yes, because the effects of muscle relaxants can be potentiated by antihistamines.
