Endocet Side Effects

Endo Pharmaceuticals produces Endocet in tablet form in various strengths. Each Endocet contains 5 mg, 7.7 mg or 10 mg of oxycodone. Every tablet also contains 325 mg, 500 mg or 650 mg of acetaminophen.
Physicians prescribe Endocet to relieve moderate to moderately severe pain. Recreational users consume Endocet because of the euphoric feeling it provides.

Oxycodone is a semi-synthetic opioid pain reliever. Pharmacologists create oxycodone from thebaine, extracted from the poppy plant, Papaver somniferum. Opioids such as oxycodone bind to special receptors at nerve endings to send messages of pleasure to the brain; oxycodone changes the way the brain perceives pain.

Oxycodone, as with other opioids, also acts directly on the breathing center in the brain to reduce cough. Opioids also work in the gastrointestinal tract to slow down digestion and ease diarrhea.

Acetaminophen is a less potent pain reliever that also reduces fever. Acetaminophen works by inhibiting the production of prostaglandin, a natural chemical that produces pain, inflammation and fever. Together, acetaminophen and oxycodone relieve pain more completely than either medication could alone.

Side Effect Information

All drugs, including Endocet, can cause side effects in some people. Many Endocet consumers experience no side effects or minor adverse reactions. Most commonly reported side effects are not serious and disappear after using Endocet as prescribed for a few days. Some people experience serious side effects, requiring the immediate medical attention.

The adverse reactions commonly associated with Endocet are typical of any opioids. Opioid use may cause respiratory depression, a serious breathing problem. Respiratory depression can lead to slowed breathing, stopped breathing, circulatory collapse, dangerously low blood pressure and shock. Symptoms of respiratory depression include slow or shallow breathing, unusual breathing patterns and a bluish color around the eyes, mouth and fingertips.

Most people tolerate acetaminophen at therapeutic doses.

Abuse, Addiction and Dependence

Oxycodone causes euphoria - recreational users abuse Endocet to get high. The U.S. Drug Enforcement Agency, or DEA, classifies substances according to its potential for abuse, and classifies the oxycodone in Endocet as a Schedule II narcotic, which means Endocet carries the same risk for abuse as opium or OxyContin.

Abusing a drug means to use it non-medically in hopes of getting high or to treat a condition other than the one for which it was prescribed. Non-medical use and repeated doses of Endocet can cause physical and psychic dependence, and an increased tolerance to oxycodone.
A doctor will diagnose an individual as being opioid-dependent if the patient suffers withdrawal symptoms when he stops using Endocet. An addicted person feels cravings and engages in drug-seeking behavior when his supplies run low. Increased tolerance means the individual must take stronger doses of Endocet more often to achieve the same pain-relieving or euphoric effect; lowered tolerance means a person is more sensitive to the effects of Endocet.

Withdrawal symptoms come in two phases, and last five or more days with the worst symptoms appearing on or about the fourth day.
Early symptoms of withdrawal include:

  • Agitation
  • Anxiety
  • Muscle aches
  • Increased tearing
  • Insomnia
  • Runny nose
  • Sweating
  • Yawning

Late symptoms of withdrawal include:

  • Abdominal cramping
  • Diarrhea
  • Dilated pupils
  • Goose bumps
  • Nausea
  • Vomiting

Most Frequently Observed Endocet Side Effects
