How does tramadol work?

Tramadol works by altering how your brain perceives pain. Cells in our bodies have proteins called receptors. These receptors bind to signalling molecules and initiate a physiological response. Different types of receptors are specific for different molecules. For example, dopamine receptors bind dopamine, insulin receptors bind insulin, while opioid receptors bind opioids. Tramadol is an opioid which binds to mu opioid receptors in the central nervous system (CNS). The central nervous system is made up of the brain and spinal cord.

Tramadol also works by inhibiting the reuptake of serotonin and norepinephrine. Serotonin and norepinephrine are neurotransmitters. Neurotransmitters send messages from one nerve to another. Inhibiting these neurotransmitter increases the levels of these two neurotransmitters.

How to take tramadol

Take Tramadol as directed by your doctor. Do not take more than prescribed by your doctor. Do not take it more often than prescribed and do not take more than the length of time you were prescribed it. Ensure you stop taking it at the time your doctor directed you to stop.

Fast acting tramadol capsules, tablets and drops are usually every taken every 4 to 6 hours as required for pain relief while slow acting tramadol is taken once or twice a day. It can be taken with or without food. Tramadol like most pain medications work best when taken as soon as you feel pain as it may not work as much if the pain has worsened.

The dose you are prescribed will depend on the reason you are taking it and how you respond to treatment. Your doctor may start you at a lower dose and gradually increase this dose. This is done to reduce your risk of getting side effects.

The maximum recommended dose which you should not exceed is 400 milligrams per day.

It is important that you do not suck, crush, chew or break slow release preparation as doing that may disrupt the slow release system. This means that instead of releasing the drug slowly either 12 or 24 hours, the whole dose is releases at once into your body. This can lead to overdose which may be fatal.

What if I forget to take it?

What if I take too much?

Let your doctor know immediately if you take more tramadol than prescribed.
