Stadol Side Effects

Doctors prescribe Stadol to relieve a patient's moderate to severe pain resulting from injury, illness or surgery. Surgeons sometimes recommend Stadol before an operation to prevent pain and decrease the patient's awareness before or during surgery. The active ingredient in Stadol is butorphanol. This drug is similar to morphine; pharmacologists consider this drug more potent than Demerol.

Stadol is an opioid, derived from alkaloids from the poppy plant. Americans consume most of the opioid pain relievers on earth. Even though Americans account for about 5 percent of global population, they consume 80 percent of the world's supply of opioids, according to the Institute of Addiction Medicine.

Side Effect Information

Stadol, like all medicine, may cause side effects. Many people experience no, or minor, adverse reactions after taking Stadol. Most side effects are not serious and go away after a few days at prescribed doses. Some adverse reactions may be serious, requiring the attention of a medical professional.

Abuse, physical dependence and addiction are possible side effects associated with Stadol use. The U.S. Drug Enforcement Agency, or DEA, classifies substances according to the potential for abuse. The DEA has classified this drug as a Schedule II narcotic, which means it carries a high potential for abuse and mental or physical dependence.

There are more cases of drug abuse associated with the nasal form of Stadol than with the injectable formula. Prolonged drug abuse often results in physical dependence or addiction. Physical dependence means the individual will suffer withdrawal symptoms when he stops taking Stadol. Withdrawal symptoms include:

  • Abdominal Cramps

The adverse reactions to this drug are similar to side effects associated with other opioids. The most serious side effect is respiratory problems potentially leading to stopped breathing, circulatory depression, dangerously low blood pressure and shock. Physicians should expect side effects and treat patients accordingly.

Whenever you take any opioid such as Stadol, you are at risk for the serious breathing condition known as respiratory depression. Respiratory depression is a dangerous medical emergency that is sometimes fatal. During respiratory depression, your lungs do a poor job of exchanging oxygen for carbon dioxide and other blood gases. Symptoms of respiratory depression include slow or shallow breathing, unusual breathing patterns, gasping or wheezing, and a bluish tint around your eyes, mouth and fingertips.
