Action

Hydrocodone, phenylephrine and pyrilamine is a cough suppressant, decongestant and antihistamine that work together to provide more adequate symptom relief than any single drug could provide alone. Hydrocodone works directly on your medulla, the part of the brain responsible for the cough reflex. In animal studies, the cough-suppressing action of codeine takes effect about 15 minutes after oral administration, reaching peak effectiveness 45 minutes to an hour after ingestion. Cough-suppression wears off after about three hours. Phenylephrine is a decongestant that makes it easier to breathe through your nose by shrinking the blood vessels inside the delicate lining of the nasal passages. Pyrilamine is an antihistamine that works by reducing the level of histamines in your body; histamines cause small blood vessels to dilate, allowing fluids to seep from blood vessels into surrounding tissues and cause symptoms such as watery eyes and runny nose. Histamines also indirectly stimulate the production of thick, sticky mucus. More About How Hydrocodone, Phenylephrine, Pyrilamine Works

Precautions

Seek immediate medical help at first onset of symptoms of an allergic reaction; a person's condition can deteriorate quickly and without warning. Anaphylaxis is a severe form of an allergic reaction that usually occurs within minutes of exposure. Without medical help, death from anaphylaxis can occur within 15 minutes of contact to the allergen. Common symptoms of a mild allergic reaction include hives, especially over the face and neck, nasal congestion, itching, rashes and watery, red eyes.

  • Abdominal Pain or Stomach Cramps.
  • Chest Discomfort or Tightness.

Abuse

Drug abuse means to use drugs for recreational purposes or outside the recommendations of the prescribing physicians. Hydrocodone is one of the most widely abused drugs on the street today because, in part, it is one of the most widely prescribed drugs on the market. Abusers can get hydrocodone by visiting multiple doctors under assumed names, filing bogus prescriptions with pharmacies by phone or in person, stealing it from friends, family members and strangers or by buying it on the street.

Withdrawal

Withdrawal from prescription drugs such as hydrocodone, phenylephrine and pyrilamine is a normal, predictable consequence of using high doses of opioids or using these drugs for a long period of time. Withdrawal is a physiological process, not a barometer of moral character or an absolute indication that a person has been using drugs illegally. In fact, many people suffer withdrawal symptoms after release from a hospital stay in which they used large doses of opioids to help them deal with pain resulting from a bad injury or acute illness. Unless a patient consciously connects the symptoms to her drug use, she may assume she caught the flu while in the hospital and suffer through the unpleasant withdrawal symptoms alone. If she associates symptoms relief with the drug, she may develop cravings and addictive behavior. Withdrawal symptoms include:

  • Anxiety.
  • Fast Pulse.
  • Fever.
  • Goose Bumps, Abnormal Skin Sensations.
  • Hallucinations.
  • Nausea, Vomiting and Diarrhea.
  • Pain.
  • Rigid Muscles.
  • Runny Nose or Sneezing.
  • Shivering or Tremors.
  • Sweating.
  • Trouble Sleeping.

Detox

Drug detoxification and rehabilitation is a collective of therapies, each of which addresses a different facet of drug dependence. Drug detoxification, commonly known as detox, purges hydrocodone or other opioids from your body, reduces overpowering withdrawal symptoms, restores chemical balance and lessens the physiological effects of drug dependence. Rehabilitation programs often include counseling and other social services to help you deal with other factors that may have added to or been the result of your dependence on drugs. Withdrawal symptoms can be overpowering and the worst withdrawal symptoms can incapacitate even the strongest and most disciplined person for several days. Rapid detox programs are emerging that promise a safe, effective and humane alternative to standard detoxification. During rapid detox, doctors administer sedatives and anesthesia along with the standard detoxification and stabilization drugs so the patient sleeps through the procedure. When the patient awakens, they have no recollection of the unpleasant withdrawal symptoms.
