What safety measures should you take when your child is taking methocarbamol?

There are some medicines that should not be taken together with methocarbamol or in some cases the dose of methocarbamol or the other medicine may need to be adjusted. It is important that you tell your doctor and pharmacist if your child takes any other medications (prescription, over-the-counter or herbal).

Some medications can cause added side effects when taken with methocarbamol. These include:

• strong pain medicine, such as morphine
• medicine for depression, such as citalopram
• medications for seizures, such as phenobarbital
• medications for nausea, such as Gravol
  
• lorazepam or diazepam

Methocarbamol may make your child dizzy, drowsy, and less alert than normal. Watch carefully when your child is doing something that she needs to be alert for, such as climbing stairs or riding a bike. Sometimes drowsiness may be preferred if the muscle pain is causing difficulty sleeping at night. In this case, you can give methocarbamol at nighttime.

Methocarbamol may also affect the results of some urine tests. If your child is getting a urine test done, tell your doctor about the medications she is taking.

What other important information should you know?

• Keep a list of all medications your child is on and show the list to the doctor or pharmacist.
