Vicodin adverse effects

Adverse effects of Vicodin

Vicodin can be addictive. But not only that, there are a number of unwanted side effects that can come with taking the prescription pain reliever. According to Vicodin’s manufacturer, Abbott Laboratories:

The most frequently reported adverse reactions include: lightheadedness, dizziness, sedation, nausea and vomiting. These effects seem to be more prominent in ambulatory than in nonambulatory patients and some of these adverse reactions may be alleviated if the patient lies down.

Other adverse effects of Vicodin may appear after long-term use of Vicodin (more than 6 weeks), or after a large dose of Vicodin has been taken. Some possible side effects with adverse consequences include:

  • anxiety
  • constipation
  • drowsiness
  • dysphoria (the opposite of euphoria)
  • fear
  • hearing impairment
  • impaired mental performance
  • impaired physical performance
  • intense itching (pruritus)
  • lethargy
  • mental dependence (addiction)
  • mental fog
  • mood changes
  • skin rash
  • spasm of vesicle sphincters
  • urethral spasm
  • urinary retention

More serious adverse side effects of Vicodin

In addition to the side effects listed above, taking Vicodin over longer periods of time or in large doses can result in more serious side effects. These include:

1. Breathing problems – Respiratory depression (slower breathing), irregular or periodic breathing are possible side effects of taking Vicodin, especially during overdose. Vicodin contains hydrocodone, an opioid agonist similar to codeine. This active ingredient can act directly on the brain stem respiratory center in high doses or in sensitive people. Hydrocodone also affects the brain center that controls respiratory rhythm, and “may produce irregular and periodic breathing.”

2. Increased pressure in the head – The effects of narcotics like Vicodin can elevate cerebrospinal fluid pressure . This is especially troublesome for people with head injuries, brain lesions or a preexisting pressure.

3. Hearing impairment or loss – People who chronically use too much Vicodin can experience hearing impairment or permanent loss of hearing.

I’ve been taking this drug for 8 weeks for knee pain due to arthritis. It works well BUT after I time I started to get slurred speech. This has persisted even after stopping the drug for over 3 days. The withdrawal is terrible. My advice – do NOT take this drug ever. It’s not worth the side effects. I’m sorry I ever took it.
