Andrei Popov

General medicinePain medicine7 years of experience

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 Singulair and what is it used for

What is Singulair

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

How Singulair works

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

When to use Singulair

Your doctor has prescribed Singulair to treat your child's asthma and prevent asthma symptoms during the day and night.

  • Singulair is used to treat patients between 6 months and 5 years of age who are not adequately controlled with their medication and need additional treatment.
  • Singulair is also used as an alternative treatment to inhaled corticosteroids in patients between 2 and 5 years of age who have not recently taken oral corticosteroids for their asthma and have shown that they are unable to use inhaled corticosteroids.
  • Singulair also helps prevent exercise-induced narrowing of the airways in patients 2 years of age and older.

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

What is asthma?

Asthma is a chronic disease.

Asthma includes:

  • difficulty breathing due to narrowing of the airways. This narrowing of the airways worsens and improves in response to various diseases.
  • airways that are sensitive and react to many things, such as cigarette smoke, pollen, cold air, or exercise.
  • swelling (inflammation) of the inner layer of the airways.

Asthma symptoms include: Coughing, wheezing, and chest congestion.

Doctor consultation

Not sure if this medicine is right for you?

Discuss your symptoms and treatment with a doctor online.

2. What you need to know before your child takes Singulair

Tell your doctor about any allergy or medical problem your child has now or has had.

Do not give Singulair to your child

  • if they are allergic to montelukast or any of the other ingredients of this medicine (listed in section 6).

Warnings and precautions

Consult your doctor or pharmacist before giving Singulair to your child.

  • If your child's asthma or breathing worsens, tell your doctor immediately.
  • Singulair oral is not indicated for the treatment of acute asthma attacks. If an attack occurs, follow the instructions your doctor has given your child. Always have your child's rescue inhaler medication for asthma attacks.
  • It is important that your child uses all the asthma medications prescribed by their doctor. Singulair should not be used instead of other asthma medications that your doctor has prescribed for your child.
  • If your child is being treated with asthma medications, they should be aware that if they develop a combination of symptoms such as flu-like illness, tingling or numbness of arms or legs, worsening of lung symptoms, and/or skin rash, they should consult their doctor.
  • Your child should not take acetylsalicylic acid (aspirin) or anti-inflammatory medications (also known as non-steroidal anti-inflammatory drugs or NSAIDs) if they make their asthma worse.

Several neuropsychiatric events (such as changes in behavior and mood, depression, and suicidal tendencies) have been reported in patients of all ages treated with montelukast (see section 4). If your child develops these symptoms while taking montelukast, they should contact their doctor.

Children and adolescents

For pediatric patients under 18 years of age, other formulations of this medicine are available based on the age range.

Other medicines and Singulair

Tell your doctor or pharmacist if your child is taking, has recently taken, or might take any other medicines, including those obtained without a prescription.
