How does painkiller affect the brain?

Can medication affect your brain?
All drugs, including cough and cold medicines, change the way the brain works by changing the way nerve cells communicate. Nerve cells, called neurons, send messages to each other by releasing chemicals called neurotransmitters. These neurotransmitters attach to molecules on neurons called receptors.
What happens if you take painkillers everyday?

How long can you take painkillers for?
Like all medicines, painkillers should be taken for the shortest period of time possible, in the lowest dose that controls your pain. This is to help avoid any side-effects. Most people only need to take painkillers for a few days (for example, for toothache) or weeks (having pulled a muscle).

That’s especially true for people with current or past liver disease or who drink more than 3 alcoholic beverages a day.
