Can You Take Too Much Clonidine?
Clonidine hydrochloride (
Catapres®,
Catapres-TTS®,
Duraclon®,
Kapvay™, Nexiclon
® XR) is a prescription medication that belongs to a class of drugs known as alpha-2 adrenergic agonists. As with most medications, it is possible to take too much clonidine. The specific effects of a clonidine overdose can be dangerous but will vary, depending on a number of factors, including the
clonidine dosage and whether it was taken with any other medications or substances.
An overdose with clonidine may cause the following problems:
- High blood pressure at first, followed by low blood pressure
- A slow heart rate
- Shallow or slow breathing
- Low body temperature
- Drowsiness
- Decreased reflexes
- Weakness
- Irritability
- Constricted, pinpoint pupils
- An irregular heart rhythm
- Coma
- Seizures.
Treatment for a Clonidine Overdose
The treatment for an overdose will vary.
If the overdose was recent, a healthcare provider may give certain medicines or place a tube into the stomach to "pump the stomach." In general, vomiting should not be induced. Treatment will also involve supportive care, such as:
- Close monitoring of vital signs
- Giving medications to increase and control the heart rate
- Giving IV fluids and medications to increase blood pressure
- Giving medications to increase breathing.
It is important that you seek medical attention immediately if you believe that you may have taken a clonidine overdose.
