Andrei Popov

General medicinePain medicine7 years of experience
Licence no. 464628925

Dr. Andrei Popov is a General Practitioner with specialized training in chronic pain. He provides online consultations for adult patients in Spain and other European countries.

Dr. Popov understands that seeking help with weight-related concerns or pain that has persisted for months can be difficult. Many patients come to him after trying different approaches without feeling truly heard. During the consultation, the doctor creates a comfortable and supportive, non-judgmental environment where the patient’s medical history can be discussed in detail, questions can be answered, and the next steps can be decided together.

Weight Management and Metabolic Health

Dr. Popov can help assess overweight, obesity, and related conditions such as hypertension, diabetes, or metabolic disorders. During the consultation, the patient’s medical history, test results, current medications, and previous treatments will be reviewed.

If you would like to learn about possible medication options or have already started treatment, the doctor can assess your situation, review the effectiveness and tolerability of the therapy, and clearly explain its benefits, potential risks, and alternatives.

Not every patient requires the same treatment. A consultation does not guarantee a prescription — it provides an objective medical assessment and a plan tailored to your individual situation.

Pain and General Medicine

You can also consult Dr. Popov regarding:

* chronic pain, migraines, neuralgia, and fibromyalgia;

* back, neck, lower back, or joint pain;

* hypertension, diabetes, and follow-up of chronic conditions;

* review of test results, medical reports, and current treatment;

* preventive medicine and a second medical opinion.

How the Consultation Works

The video consultation lasts up to 30 minutes. The doctor will listen carefully, review the information you provide, and explain the next steps in clear and understandable language.

If additional tests, an in-person consultation, or urgent medical care are required, the doctor will inform you directly.

Dr. Popov’s goal is to make sure the patient feels heard and leaves the consultation with a clear understanding of their condition and the next steps they can take.

1. What is Montelukast VIR and what is it used for

Montelukast is a leukotriene receptor antagonist that blocks substances called leukotrienes.

How Montelukast Vir works

Leukotrienes cause narrowing and swelling of the airways in the lungs. By blocking leukotrienes, montelukast improves asthma symptoms and helps control asthma.

When to use Montelukast Vir

Your doctor has prescribed montelukast to treat asthma and prevent asthma symptoms during the day and night.

  • Montelukast is used to treat pediatric patients between 6 and 14 years of age who are not adequately controlled with their medication and need additional treatment.
  • Montelukast is also used as an alternative treatment to inhaled corticosteroids in patients between 6 and 14 years of age who have not recently taken oral corticosteroids for the treatment of their asthma and have demonstrated that they are unable to use inhaled corticosteroids.
  • Montelukast also helps prevent airway narrowing caused by exercise.

Depending on the symptoms and severity of your asthma or your child's asthma, your doctor will determine how to use montelukast.

What is asthma?

Asthma is a chronic disease.

Asthma includes:
