What is Percocet, and what is it used for?
Percocet (oxycodone/acetaminophen) is a strong narcotic pain-reliever and cough suppressant similar to morphine, codeine, and hydrocodone. Percocet is prescribed for the relief of moderate to moderately severe pain.
- The precise mechanism of action of oxycodone is not known but may involve stimulation of opioid (narcotic) receptors in the brain. Oxycodone does not eliminate the sensation of pain but decreases discomfort by increasing tolerance to pain. In addition to tolerance to pain, oxycodone also causes sedation and respiratory depression.
- Acetaminophen is a non-narcotic pain reliever and antipyretic (fever reducer). Acetaminophen relieves pain by elevating the threshold to sensing pain. It reduces fever through its action on the heat-regulating center of the brain.
- The combination of oxycodone and acetaminophen achieves greater pain relief than either taken separately.
- The FDA approved oxycodone/acetaminophen combinations in February 1980.
What are the side effects of Percocet?
The most frequent adverse reactions of Percocet (oxycodone/acetaminophen) include:
Other important side effects include:
- Spasm of the ureter, which can lead to difficulty in urinating
Possible serious side effects include:
- Severe reduction in blood pressure (hypotension)
- Paralytic ileus
- Serious allergic reactions
- Severe skin reactions
Oxycodone can depress breathing and, therefore, is used with caution in elderly, debilitated patients and in patients with serious lung disease. Oxycodone can impair thinking and the physical abilities required for driving or operating machinery.
Is Percocet addictive?
- Percocet can be habit-forming. Mental and physical dependence can occur, but are unlikely when used for short-term pain relief.
What is the dosage for Percocet?
- The dose of Percocet (oxycodone/acetaminophen) is variable and depends on the needs of the patient and specific circumstances.
- The usual dose is one tablet every six hours as needed.
- The maximum Percocet dose is 60 mg/4 g per day.
Which drugs interact with Percocet?
- Oxycodone, like other narcotic pain-relievers, increases the effect of drugs that slow brain function, such as alcohol, barbiturates, skeletal muscle relaxants, for example, carisoprodol (Soma), cyclobenzaprine (Flexeril), and benzodiazepines such as diazepam (Valium) and lorazepam (Ativan). A combined use of muscle relaxants or benzodiazepines and oxycodone may lead to increased respiratory depression.
- Since oxycodone causes constipation, the use of antidiarrheals, for example, diphenoxylate (Lomotil) and loperamide (Imodium), in persons taking oxycodone, can lead to severe constipation.
- Drugs which stimulate and also block opioid receptors, for example, pentazocine, nalbuphine (Nubain), butorphanol (Stadol), and buprenorphine (Subutex) may reduce the effect of oxycodone and may precipitate withdrawal symptoms.
- A fatty meal may increase the absorption of oxycodone by 27%.

Is Percocet safe to use during pregnancy or while breastfeeding?
- Safety of oxycodone/acetaminophen during pregnancy has not been established. Newborns of mothers who were taking oxycodone for a prolonged period may exhibit respiratory depression or withdrawal symptoms.
- Small amounts of oxycodone are secreted in breast milk and may cause side effects in the newborn.

Drug Abuse and Addiction
Drug abuse and addiction is a chronic disease that causes drug-seeking behavior and drug use despite negative consequences to the user and those around him. Though the initial decision to use drugs is voluntary, changes in the brain caused by repeated drug abuse can affect a person's self-control and ability to make the right decisions and increase the urge to take drugs. Drug abuse and addiction are preventable.
Kidney pain has a variety of causes and symptoms. Infection, injury, trauma, bleeding disorders, kidney stones, and less common conditions may lead to kidney pain. Symptoms associated with kidney pain may include fever, vomiting, nausea, flank pain, and painful urination. Treatment of kidney pain depends on the cause of the pain.
What Is the Strongest Painkiller?
The most powerful pain reliever is a class of medications known as “opioids,” which have a significant risk of addiction and dependency. These drugs are routinely recommended by doctors for severe pain treatment, as well as a variety of other illnesses.
Tylenol Liver Damage
Tylenol liver damage (acetaminophen) can occur from accidentally ingesting too much acetaminophen, or intentionally. Signs and symptoms of acetaminophen-induced liver damage may include: nauseau, vomiting, kidney failure, bleeding disorders, coma, and death. Acetaminophen is a drug contained in over 200 OTC and prescription medications from NyQuil to Vicodin. Avoiding unintentional overdoses include reading medication labels, write down the dosages of medications you are taking, do not drink excessive alcohol while taking acetaminophen. In severe cases, a liver transplant may be necessary.
Acute injuries, medical conditions, and chronic use conditions are causes of knee pain. Symptoms and signs that accompany knee pain include redness, swelling, difficulty walking, and locking of the knee. To diagnose knee pain, a physician will perform a physical exam and also may order X-rays, arthrocentesis, blood tests, or a CT scan or MRI. Treatment of knee pain depends upon the cause of the pain.
Lower Back Pain (Lumbar Spine Pain)
There are many causes of back pain. Pain in the low back can relate to the bony lumbar spine, discs between the vertebrae, ligaments around the spine and discs, spinal cord and nerves, muscles of the low back, internal organs of the pelvis, and abdomen, and the skin covering the lumbar area.
Drug-Induced Liver Disease
Drug-induced liver diseases are diseases of the liver that are caused by physician-prescribed medications, OTC medications, vitamins, hormones, herbs, illicit (recreational) drugs, and environmental toxins.

Shoulder and Neck Pain
Shoulder and neck pain may be caused by bursitis, a pinched nerve, whiplash, tendinitis, a herniated disc, or a rotator cuff injury. Symptoms also include weakness, numbness, coolness, color changes, swelling, and deformity. Treatment at home may incorporate resting, icing, and elevating the injury. A doctor may prescribe pain medications and immobilize the injury.
Pain management and treatment can be simple or complex, according to its cause. There are two basic types of pain, nociceptive pain and neuropathic pain. Some causes of neuropathic pain include: complex regional pain syndrome, interstitial cystitis, and irritable bowel syndrome. There are a variety of methods to treat chronic pain, which are dependant on the type of pain experienced.
Neck Pain (Cervical Pain)
Neck pain (cervical pain, cervicalgia) may be caused by any number of disorders and diseases. Tenderness is another symptom of neck pain. Though treatment for neck pain really depends upon the cause, treatment typically may involve heat/ice application, traction, physical therapy, cortisone injection, topical anesthetic creams, and muscle relaxants.
Muscle Pain (Myofascial Pain Syndrome)
Muscle pain (myofascial pain syndrome) is muscle pain in the body's soft tissues due to injury or strain. Symptoms include muscle pain with tender points and fatigue. Treatment usually involves physical therapy, massage therapy, or trigger point injection.
Arthritis, bursitis, IT band syndrome, fracture, and strain are just some of the causes of hip pain.
