Effects of Ketorolac

It is thought that blocking the effects of prostaglandins is what makes ketorolac useful for reducing pain. In clinical studies, ketorolac was as effective as lower doses of narcotics at treating pain. When it was combined with narcotic pain medicines (such as morphine), it decreased the amount of narcotics needed. Also, pain relief was significantly better in those receiving ketorolac and morphine compared to those receiving morphine alone.
 
Pain relief usually begins about 30 minutes after the dosage is received. The maximum effect of ketorolac occurs within two to three hours and lasts, on average, for four to six hours.
 

When and How Do I Take It?

Some general considerations for when and how to take the medication include the following:
 
  • Ketorolac comes in tablet form. It also can be given by injection or through an intravenous line (IV).
     
  • To avoid an upset stomach, take your ketorolac with food or milk.  

 

  • For ketorolac to work properly, you have to take it as prescribed. It will not work if you stop taking it.
     

Dosing

The dose of ketorolac your healthcare provider recommends will vary depending on a number of factors, including:
 
  • Your weight
  • Your age
  • Other medical conditions you may have
  • Other medications you may be taking.
     
As with any medication, do not adjust your dose unless your healthcare provider specifically instructs you to do so.
