Chronic drug use can lead to the buildup of what’s known as drug tolerance. This can occur in people who take prescribed medication, or those who misuse substances like heroin or alcohol.
A high drug or alcohol tolerance is common in those with a substance abuse problem, or a drug addiction, and can cause a person to take more of a drug over time.
Here you will find information on what drug and alcohol tolerance is, types of drug tolerance, and how to get help for drug or alcohol abuse.
Understanding Alcohol And Drug Tolerance
Drug tolerance can develop through the use of any drug that affects the body’s brain and nervous system. For instance, taking a prescribed medication for several weeks or months.
Drug tolerance occurs when the body becomes used to the presence of the drug in the body. It will adapt to the dose you’re taking, and stop working as well.
This will require that you take more of the drug—either at a higher dose, or more frequent doses—in order to feel the same strength of drug effects as before.

Tolerance And Substance Abuse
What’s important to know about drug tolerance is that it can develop in anyone, regardless of whether you are misusing a substance.

Antidepressant Drug Tolerance

The use of selective serotonin reuptake inhibitors (SSRIs) like Zoloft can lead to rapid tolerance or Tachyphylaxis.
