Risks and warnings for Ketamine (Ketalar)
Ketamine (Ketalar) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Unstable vital signs
Ketamine (Ketalar) can often cause temporary changes in blood pressure and heart rate. Some people can also experience an irregular heartbeat and other heart problems with this medication. Your provider will check your vital signs and heart while you receive ketamine (Ketalar).
Reactions after waking
Ketamine (Ketalar) can make some people feel confused or distressed after waking up from their surgery or procedure. This medication can also cause you to have hallucinations (see or feel things that aren't real) or feel like you're in a dream-like state, which can lead to confusion, excitement, or acting without logical thinking. This effect can last a few hours depending on your ketamine (Ketalar) dose and how the medication was given. To lower the chances of having these reactions, your provider might give you other medications as part of anesthesia or make sure the room is quiet when you're waking up from your surgery or procedure.
Breathing problems
Receiving too much ketamine (Ketalar) or too fast can cause breathing problems. Your provider will monitor your breathing and oxygen level during your treament. They'll adjust your dose appropriately to prevent this from happening.
Risk in newborns and children
It's unclear if ketamine (Ketalar) is safe for pregnant women, their unborn babies, and children under 16 years old. Anesthetic medications can be necessary for certain surgeries or procedures, depending on the risks and benefits. Discuss with your or your child's provider about how safe ketamine (Ketalar) is for your child.
Liver problems
- Risk factors: Using ketamine (Ketalar) over and over again

Interactions with other medications

Taking ketamine (Ketalar) together with theophylline or aminophylline can make it easier to have a seizure. Other medications can make the effects of ketamine (Ketalar) stronger. When ketamine (Ketalar) is used with medications that slow down the body, such as opioids, benzodiazepines, or alcohol, it can lead to excessive sleepiness, breathing problems, coma, and death. Depending on the medications you need to receive with ketamine (Ketalar), your provider might adjust your dose and monitor you more closely to make sure it's safe for you.

Ketamine (Ketalar) is a controlled medication because of the risk for abuse, misuse, and dependence. Abuse is when the medication is purposely used for a non-medical reason, like the feeling of pleasure or happiness (euphoria). Misuse is when the medication is taken for reasons other than prescribed. Abusing and misusing ketamine (Ketalar) can cause anxiety, unhappiness, confusion, trouble sleeping, and hallucinations (seeing or hearing things that aren't there). In addition, taking ketamine (Ketalar) at higher doses or for a long time might lead to dependence. This is when your body depends on the medication to function properly, which can cause withdrawal symptoms if you stop taking it suddenly. Withdrawal symptoms can include craving, tiredness, poor appetite, and anxiety. To prevent these risks, your provider will make sure you're receiving ketamine (Ketalar) at the right dose for the right amount of time. If you have a history of substance abuse or misuse, speak to your provider before receiving ketamine (Ketalar), and they can determine a safer option for you.
