Toradol

• Toradol is indicated for conditions involving extreme pain. Toradol's prescription is only short-term, up to five days, to treat extreme pain caused by surgery. It is administered either as a stand-alone drug or in combination with other medications.
  
  Toradol side effects include allergic reaction, hives, shortness of breath, and swelling of the face, lips, tongue and throat. Other side effects that need immediate medical attention are black or bloody stools, coughing or vomiting of blood, speedy weight gain, urinating less than the usual, nausea, stomach pain and loss of appetite.
  
  

Morphine Sulfate

• Morphine sulfate is injected every four hours for patients suffering from extreme pain. Its prescription by a doctor will depend on several factors such as the medical history of the patient. According to the National Institute of Drug Abuse, morphine is a form of opiate that can be addictive when used at an inappropriate dosage. Withdrawal symptoms such as sweating, restlessness, muscle twitches, hot flushes, increased blood pressure and heart rate, nausea and vomiting are imminent among patients who abruptly stop using the medication; hence it is not advisable to stop the dosage without prior notice from a physician.
  
  The most dangerous side effect of morphine sulfate is respiratory depression, with a higher risk among the geriatric population and individuals with respiratory problems.
  
  

Demerol

• Demerol is another injectable pain reliever similar to morphine. It is used to treat moderate to severe inflammatory and pain responses of the body. Demerol may be habit-forming, and like all of these medications, should never be used unless prescribed by a doctor. Demerol should not be given to a patient who has a history of drug abuse or addiction.
  
  Get immediate medical attention if side effects develop, such as slow heart beat, convulsions, clammy skin, confusion, extreme weakness, dizziness and fainting. Demerol should not be used together with other narcotic pain drugs, sedatives or tranquilizers because they may worsen the side effects of Demerol.
  
  

Cortisone

• Cortisone is a very powerful anti-inflammatory drug that can relieve pain and inflammation. Severe inflammation may require more than one shot of cortisone. Relief from pain is experienced as the inflammation subsides.
  
  The most common side effect is a "cortisone flare," where the cortisone crystallizes, causing the patient to suffer temporary pain that may last up to two days. The pain is manageable with ice application on the affected area. It is also possible that whitening on the injected area will occur; but it is a temporary and harmless reaction to the drug.
  
  

Diclofenac

• Diclofenac shots may reduce hormones that are responsible for pain and inflammation. It can primarily reduce the inflammation caused by rheumatism and other painful conditions.
  
  However, diclofenac administration requires strict supervision by medical personnel because of the risk of cardiac and circulatory problems. Diclofenac should be avoided if the patient underwent bypass surgery or artery bypass graft.
