Are you Vicodin-tolerant?

Are your Vicodin strengths not enough?  Does Vicodin (a combination of hydrocodone bitartrate and acetaminophen) seem to no longer be effective when you take it?   Do you find yourself having to take more Vicodin in order to feel its effect? If your answer to these questions are, “Yes!” then your body has probably developed a tolerance to Vicodin.

Once people have developed a tolerance to Vicodin they become worried that this means they’re addicted to Vicodin, as well. Not true. Tolerance to Vicodin does not necessarily indicate addiction to Vicodin.  But you can experience withdrawal symptoms from hydrocodone.   In this article, we’ll take a closer look at Vicodin tolerance. We also look at how Vicodin tolerance relates to chemical dependency and addiction. We invite any questions you may have about Vicodin at the end of this article.

Vicodin tolerance symptoms

There are two main symptoms of Vicodin tolerance:

1. Your doctor needs to continually increase the dose of hydrocodone for it to work.

2. You can’t tell a difference (therapeutically) whether you are on or off Vicodin.

If you experience either of these symptoms, don’t jump to the assumption that you are addicted to Vicodin. Most physicians anticipate that you will develop a tolerance to Vicodin. Tolerance is a normal occurrence with most people taking Vicodin.

Developing tolerance to Vicodin

When your body develops tolerance to Vicodin (or any medication), you need may need to take Vicodin more frequently or in higher doses in order to achieve the initial therapeutic effect of Vicodin that occurs when you FIRST start taking the pain killer. So what causes this phenomenon? And who is more likely to become tolerant of Vicodin?

Anyone at any time can develop a tolerance to Vicodin. However, the cause of developing a tolerance to Vicodin is not greatly known. In fact, scientists are still learning how the brain works to adapt and integrate medications such as Vicodin so that it takes higher doses for you to feel the effects of Vicodin. In general, however, it has been observed that the longer you take Vicodin, the more likely your body will develop a tolerance. Because of this tolerance your doctor may continue to increase your doses in order for you to benefit from the therapeutic pain relief effects of Vicodin.

Tolerance doesn’t mean you are dependent or addicted to Vicodin, however. There are many links between the three. Sometimes Vicodin tolerance is the precursor to creating a physical dependence on Vicodin. When you have developed a dependence on Vicodin, the body needs Vicodin in order to function. When this happens, it is important to stop taking Vicodin. Dependence on Vicodin can develop to Vicodin addiction, or can cause long term side effects of opiate use. After you stop taking Vicodin, you will need to be monitored as you will have to go through a period of opioid withdrawal.  What are symptoms of Vicodin withdrawal? Chills, nausea, and cramping are most common.

Vicodin tolerance: How long?

It doesn’t take long to develop a tolerance to Vicodin, or more accurately, the hydrocodone found in Vicodin. You can become resistant to Vicodin within in a month. But the time frame for developing tolerance to Vicodin is different for each person. Each body reacts differently to the medication they are taking. Still, Vicodin is considered one of the stronger opioid pain killers. Because of its pharmacology, Vicodin has a higher potential of developing dependence and becoming a possible drug addiction. Therefore, tolerance becomes a potential pathway for both of these outcomes.

High tolerance to Vicodin

Vicodin tablets start at doses of 7.5 mg hydrocodone and 750 mg acetaminophen. Doctors may increase Vicodin dosage as tolerance develops. It is not recommended a person should take more than five tablets a day. If it gets to the point you find yourself taking more than five tablets a day to feel the Vicodin is working your tolerance to Vicodin is high.

How to lower tolerance to Vicodin

The only way to lower your tolerance to Vicodin is to lower your doses or stop taking Vicodin all together for a while. This will give your brain time to readjust without the presence of Vicodin in the body. But this tactic can be painful for people who need Vicodin in order to treat severe pain. If Vicodin is not working, you might ask to be put on another medication to help treat pain symptoms. Make sure you’re in communication with your doctor so that pain professionals can help you figure out best option.
