Going to the dentist is a real stress for you? Fear and anxiety, muscular and psychoemotional stress worsen not only the life of patients but also make the doctor's work much more difficult. To cope with this will help premedication.

Premedication, or simply speaking — taking soothing medications, is performed prior to anesthesia and enhances the anesthetic effect. It is simply indispensable for those who are afraid of panic to treat their teeth, especially for the youngest patients.

What is the purpose of premedication?

The main task is to prevent possible reactions and complications during or after dental manipulations, including:

Suppression of fear

Relaxation of the patient

Elimination of the emetic reflex

Suppression of increased salivation

Reduction of pain sensitivity

Prevention of allergic reactions

There are 2 types of premedication — specific and nonspecific. The first usually prescribe a therapist, the second — a dentist.

Nonspecific premedication works for practically all patients, and specific one — to those suffering from obscheomatic diseases and being at risk: hypertensive people, asthmatics, people with ischemic heart disease, etc.

Types of nonspecific premedication


Has a sedative effect. Reduces mental and emotional stress, eliminates fear and anxiety, and also enhances the effect of anesthesia.

What happens in this case? Half an hour before the treatment the patient takes tranquilizers or homeopathic soothing products of plant origin. Under their action, a person relaxes, while remaining in full consciousness. The effect lasts several hours. With panic fear of dentists, it is better to take medicines not only before visiting a doctor, but also on the eve of a scheduled visit.


Completely suppresses or significantly reduces the pain threshold, strengthens the result of local anesthesia. Analgesic effect is achieved by taking painkillers — narcotic or non-narcotic. For half an hour or an hour before the dental intervention prescribe different pain medications. On average, the effect of analgesics lasts four hours.


To prevent allergic reactions to local anesthetics and pseudoallergic manifestations in response to stressful for the body situation, patients are prescribed antihistamines. Among many of popular medications used for this purpose prescribe Atarax, which also has pronounced calming effect.


Excessive salivation and gag reflex might be suppressed by a number of medications. This is very important in dental practice. Appropriate medications in this case are taken on the eve of dental procedures and / or half an hour before them.


In other words, the one that addresses several problems at once. It is this kind that is used most often and is the most convenient. Which types of premedication will be combined depends on the history of the disease.

Premedication schemes are many, but more often a combination of analgesic and sedative premedication is used. This is due to the fact that in dental practice it is most important to relieve the patient of stress and to increase the effect of anesthesia.

Premedication in pediatric dentistry

Children take a different set of drugs than adults. Premedication schedules depend mainly on the age of the child. Premedication is never prescribed for kids from 0 to 3 years of age. Medications that inhibit the mental processes and functions of the respiratory, circulatory and excretory systems are strictly prohibited for children.

Contraindications to premedication

Diseases of the liver, for example, cirrhosis

Kidney disease

Myasthenia gravis — a disease that causes pathologically fast fatigue of the striated muscles

Pregnancy and lactation

Age up to three years

There may be other individual contraindications, so you need to act only under the guidance of the doctor.

If the procedure was carried out according to the indications and with the exact observance of the dosage of medications, there should be no complications. However, some drugs have side effects and can cause a number of negative symptoms:


Dry mouth


Increased drowsiness

Premedication side effects themselves go away as soon as the drugs start to wear off. On average, four hours after admission.

Immediately after the end of dental procedures, the doctor must ensure that the patient is in an adequate state, responds normally to external stimuli and feels well. If this is not the case, the dentist contacts the patient's relatives and waits for them to arrive.
