Norepinephrine is a neurotransmitter and stress hormone produced by the adrenal gland. It is used as a drug to treat low blood pressure and can cause side effects such as hives, muscle weakness, and disorientation.
Norepinephrine is a type of neurotransmitter, which is a chemical responsible for the movement of nerve impulses between neurons. It is found in both the central and sympathetic nervous systems and is produced by the adrenal gland. In addition to acting as a neurotransmitter, this chemical also acts as a stress hormone. It has a role to play in a person’s fight or flight response, working in conjunction with adrenaline. In this role, it increases a person’s heart rate and blood flow to the muscles; it also stimulates the release of sugar into the blood and is often compared to adrenaline.
Sometimes, norepinephrine is used as a drug. It is often used to treat patients with low blood pressure, particularly the type that is considered life threatening. For example, it can be used in situations where a medical condition or medical emergency has caused a person’s blood pressure to drop unsafely. It can be used when CPR needs to be performed, for example.
Typically, this chemical is injected into a patient’s body through a large vein. It is usually given in a hospital, but can also be used elsewhere in an emergency medical situation. Depending on how quickly the patient responds to the injection, the drug may only be used for a short time, but some people need to take it for a week or more. Most patients don’t have to worry about accidentally missing doses, as a doctor usually administers the injections and patients don’t have to be reminded when it’s time to get a new dose.
While this drug can be life saving, it has the potential to cause some side effects. For example, a person may develop hives and have trouble breathing, or they may have swelling of the face, mouth, or throat. Any of these side effects should receive immediate medical attention.
Other potentially serious side effects of norepinephrine include pain or weakness in the muscles, numbness in the extremities, bluish lips and nail beds, and skin that looks discolored and feels irritated. Some people may experience nausea and vomiting, and missing normal amounts of urine is another potential side effect. Also among the serious side effects of this drug are sudden onset headaches, disorientation, speech problems, and vision changes. A patient should notify a doctor right away if they experience any of these symptoms while taking this drug.
