Understanding Ketamine Injection
A ketamine injection is a medicine that doctors and nurses give directly into the body through a needle, usually into a vein or muscle. It is used to relieve pain, help a patient relax deeply, or put them to sleep during a medical procedure so they do not feel discomfort. Your doctor may recommend it if you need an operation, a painful treatment, or emergency care that requires you to be calm and pain-free.
Common Symptoms / Concerns for Ketamine Injection
When to Seek Professional Care
Book an evaluation with a healthcare provider immediately if you experience or present with:
- Difficulty breathing or feeling like you cannot get enough air
- Chest pain that does not go away
- You stop breathing or someone around you cannot wake you up
- Very fast or irregular heartbeat that makes you feel unwell
- A seizure or uncontrolled shaking of the body
- Severe confusion that lasts a long time after the injection
- Swelling of the face, lips, or throat making it hard to swallow or breathe
- Extreme agitation or violent behaviour that cannot be calmed
What to Expect During Your Medical Consultation
Before giving the injection, the doctor or nurse will check your blood pressure, heart rate, and ask about any medicines you are taking to make sure ketamine is safe for you. The injection is given carefully through a drip in your arm or directly into a muscle, and it works quickly to help you feel relaxed or free from pain. After the procedure, a nurse will stay close to watch over you until the medicine wears off and you are fully awake and comfortable.

Frequently Asked Questions
What is ketamine injection used for?
Ketamine injection is mainly used as an anaesthetic — it puts you into a deep sleep so doctors can perform surgery or painful procedures without you feeling anything. It is also used to manage severe pain in emergencies. In some hospitals, it is given in small doses to help with certain types of long-lasting pain.
Is ketamine injection safe?
Yes, ketamine is considered safe when given by a trained health worker in a clinic or hospital. It has been used by doctors around the world for many years. Like all medicines, it must be given at the right dose and in the right setting to avoid problems.
What side effects should I expect after a ketamine injection?
Some people feel dizzy, confused, or see things that are not there (hallucinations) shortly after receiving ketamine — this is normal and usually passes quickly. You may also feel nauseous, have blurred vision, or feel like you are floating. These effects go away on their own as the medicine leaves your body.
How long do the effects of a ketamine injection last?
The main anaesthetic effect of ketamine usually lasts between 15 and 45 minutes, depending on the dose given. You may still feel drowsy or a little confused for a few hours after the injection. Your doctor or nurse will monitor you until it is safe for you to go home or move to a ward.
Can ketamine be addictive or misused?
Ketamine can be misused outside of hospitals, and regular misuse can lead to dependence. However, when it is given by a health professional for medical reasons, the risk of addiction is very low. If you have concerns about how ketamine is being used, speak openly with your doctor.
