Have you or someone you know ever been prescribed a medication by a doctor for seizures, before surgery, or for insomnia? It could be a barbiturate. While these are very useful medications, they are also medications that require a lot of caution. So, let's talk about this today.
What are barbiturates?
Simply put, these are a type of medication that calms you down (sedative), or makes you sleepy (hypnotic). They can stop and prevent conditions like seizures.
The way this medicine affects our brain is amazing. It increases the amount of a chemical in our brain called gamma-aminobutyric acid, or GABA for short. This GABA slows down the activity of brain cells. That's why we feel calm, relaxed, and sleepy.
For what situations do doctors prescribe this medication?
In the past, these were commonly used for anesthesia during surgery, due to their ability to put the patient into a deep sleep. However, today, newer medications have been developed that are better for that purpose and have fewer side effects.
However, barbiturates are still an essential medication for some medical conditions. They are sometimes used in combination with other medications, such as paracetamol.
The main uses of barbiturates are:
- To prevent seizures: Some people are given these to control ongoing seizures.
- For Insomnia: It is given as a short-term treatment for insomnia.
- To calm the patient before anesthesia: These help reduce the patient's fear before surgery and put them to sleep quickly.
- To control high pressure inside the skull (Intracranial Hypertension): These are used in some brain-related emergencies.
What are the most commonly used barbiturates?
There are several types of barbiturates around the world. However, some of them are not used in our country. Here are some of the most common:
| Drug Name | What is it mainly used for? (Main Use) |
|---|---|
| Phenobarbital | This is a name that many people in our country have heard of. It is used to prevent seizures and also to control them when they occur. |
| Butalbital | It is rarely given alone. It is used in combination with things like aspirin, paracetamol, and caffeine to treat migraines and some headaches. |
| Primidone | This is another medicine given to prevent seizures. |
| Methohexital | It is used for anesthesia during very short surgeries or tests, for example, in electroconvulsive therapy. |
What are the benefits of this medicine?
Because these are very old medications, there are decades of research data on them. Also, they can be used as a second option when first-line medications don't work.
One of the most important advantages is that they vary in their duration of action . Some only work for a very short time, like a few minutes. This is very useful for short surgeries. Others can stay in the body for hours or even days. That's one reason to keep giving them to prevent seizures.
| Category | Effective Duration |
|---|---|
| Ultra-short-acting | 15 minutes or less. (Example: Methohexital) |
| Short-acting | About 3-4 hours. (Ex: Pentobarbital) |
| Intermediate-acting | About 4-6 hours. (Ex: Butalbital) |
| Long-acting | Up to 12 hours, but may remain in the body for several days. (Ex: Phenobarbital) |
What are the risks and complications of barbiturates?
The main reason why the use of barbiturates is decreasing now is because of their risks. You should definitely be aware of this.
- Tolerance and Dependence/Addiction: Over time, the body becomes accustomed to the drug. Then the previous dose is not enough, and a higher dose is needed to get the same effect. This is called `Tolerance`. `Dependence` means that the body becomes dependent on the drug. If the drug is stopped, severe withdrawal symptoms may occur. `Addiction` means that this condition develops into a mental illness and the person cannot stop using the drug, even if it is harmful to their life.
- Heart and breathing problems: These can cause a decrease in heart rate and blood pressure. If you take too much or take the wrong dose, you may stop breathing. This is a life-threatening emergency.
- Interactions with other medications: Barbiturates affect liver function. Therefore, some other medications you take may be eliminated from your body more quickly, making them less effective.
- Risks for pregnant and breastfeeding mothers: You should avoid taking these medications if you are pregnant. They can also pass to your baby through breast milk.
The most important thing is to take your medication exactly as your doctor tells you, and for the exact time you are told. Never change the dosage or stop taking it at your own discretion.

Do not ignore these symptoms. In severe cases, this can be life-threatening.
