A fever can be a withdrawal symptom among people who have been addicted to various substances, or even after a period of intense substance use. Fever symptoms may range from mild to severe.

Definition of a Fever

Body temperature varies from one individual to the next, and according to factors like time of day and menstrual cycle, but generally, a temperature of 99 to 99.5 F (37.2 - 37.5 C) is considered to be a fever in adults.

Additional Symptoms of Fever

Along with a fever, you may have these symptoms:

  • Weakness
  • Appetite loss
  • Shivering
  • Sweating
  • Headache
  • Achy muscles
  • Dehydration

If the fever is higher than 103 F (39.4 C), you may also experience confusion, irritability, hallucinations or seizures.

Fever in Withdrawal

Doctors take withdrawal fever very seriously, and in detox, all fevers are thoroughly investigated to make sure that they are not the result of an underlying infection, which should be treated immediately.

Drug users may be more vulnerable to infections for a variety of reasons, and both drug effects and withdrawal symptoms may mask the need for urgent treatment for another condition. 

Home Treatment for Fevers

To monitor and treat your withdrawal fever at home:

  • Take and record your temperature. Abstain from smoking or hot fluids for 15-30 minutes before taking your temperature.
  • If your temperature goes above 101.3 F (38.5 , take the correct dose of acetaminophen or ibuprofen.
  • A tepid bath or sponge bath can help lower body temperature, but do not use cold or iced water, as shivering will increase internal body temperature.
  • Remove layers of clothing. Do not bundle up even if you feel chilly or shivery.
  • Drink plenty of fluids, especially water, popsicles and clear soup.

When to Seek Help for a Fever

Seek medical assistance immediately if:

  • Your temperature goes above 103 F (40 C), and doesn't come down within an hour of home treatment.
  • Your fever persists for more than 24 hours.
  • You have a serious medical illness, such as a heart problem, sickle cell anemia, diabetes, HIV or cystic fibrosis.
  • You have a seizure with the fever.

Symptoms of Addiction

Symptoms of alcohol or drug addiction may include the following:

  • Not being able to stop using the substance, even though you've tried
  • Spending money you can't afford on the substance
  • Participating in activities you normally wouldn't in order to get the substance, for example, stealing
  • Having a strong desire to regularly use the substance, whether daily or multiple times a day
  • Experiencing strong cravings for the substance
  • Concentrating more and more of your efforts on getting and using the substance
  • Making sure you have an ample supply of the substance
  • Driving or other activities that could cause injury while you are under the influence of the substance
  • Interference with your work, school or home life because of the substance use
  • Developing a tolerance for the substance so that it takes more of it to get the same effect
  • A decline in your level of personal hygiene or grooming because of the increased substance use
  • Not having as much energy or participating in as many activities as you used to
