BRONCHIAL ASTHMA
WHY BACTERIOPHAGES FOR ASTHMA?
Quick check: Phage therapy for bronchial asthma
-
Effectiveness: Targeted treatment of bacterial superinfections (e.g., caused by S. aureus) that can worsen or make asthma attacks chronic.
-
Safety: Local use (inhalation) is considered safe and preserves the beneficial flora of the airways compared with broad-spectrum antibiotics.
-
Status: Currently used mostly as part of individual compassionate-use attempts for treatment-resistant bacterial co-infections.
This article was created based on current clinical guidelines and microbiological research (March 2026) and has been medically and scientifically reviewed.
Symptoms
Symptoms and treatment for bronchial asthma
Acute asthma attacks in young children are not only due to viral infections, but are also likely due to bacterial infections. This is shown by a new study by researchers at the University of Copenhagen led by Hans Bigaard. It was published in the British Medical Journal (doi: 10.1136/bmj.c4978).
The main causes of these bacterial infections are Staphylococcus aureus and Pseudomonas aeruginosa. These bacterial infections can be treated with bacteriophages.
Phage therapy
Phage Therapy for Sinusitis
In Eastern Europe, phage therapy is used to treat bronchial asthma. In particular, those affected who already have an intolerance to antibiotics benefit from this therapy. However, antibiotics and bacteriophages are also used in combination.
The best-selling phage cocktail contains phages that lyse or kill the following bacteria:
Streptococcus pyogenes, Staphyloccus aureus, Escherichia coli, Pseudomonas aeruginosa, Proteus vulgaris, Proteus mirabilis
Staphylococcus aureus
Staphylococcus aureus
As mentioned above, in bronchial asthma the lungs are often colonized with Staphylococcus aureus or Pseudomonas aeruginosa. For this reason, this phage cocktail is used for bronchial asthma.
Buy bacteriophages for asthma
Treatment with bacteriophages is usually started immediately. Since bacteriophages have no side effects, this approach is safe.
Mögliche Bezugsquelle Phagen:
The goal of phage therapy is to bring the phages to the site where the bacteria are located.
Use of bacteriophages for asthma
In this process, approx. 5 ml of the phage cocktail is inhaled undiluted 2–3 times per day using an inhaler (compressed-air or ultrasonic nebulizer).
The treatment period is usually 10 days. If the bacteria present are difficult for the phages to access, the treatment may also take longer.
Summary:
Amount: 5 ml
Use: at least 2× per day
Duration: 10 days
Mögliche Bezugsquelle Phagen:
Diagnostics for phage therapy
If desired, phage therapy diagnostics (phagogram) can be performed beforehand to identify the disease-causing pathogen.
Mögliche Bezugsquelle Phagen:
Bacteriophages can only be effective if the corresponding host bacterium is present.
Scientific classification & evidence base
The role of the pulmonary microbiome in bronchial asthma is increasingly well established. Bacterial colonization with pathogens such as Staphylococcus aureus, Pseudomonas aeruginosa, or Haemophilus influenzae can fuel inflammatory processes in the bronchi and worsen symptoms. Phage therapy offers a precise approach here: while the Eliava Institute in Georgia has been using inhaled phage cocktails to treat chronic lung diseases for decades, European research is focusing on standardizing these therapies.
Findings from European initiatives such as PhagoBurn and specialized Belgian projects (e.g., at Queen Astrid Military Hospital) have paved the regulatory pathways for personalized phage preparations. Current data indicate that targeted reduction of the bacterial load in the lower airways can reduce the frequency of asthma exacerbations. Local administration via nebulizer is particularly efficient for achieving high phage concentrations directly at the site of infection without placing a burden on the body as a whole.
Frequently asked questions (FAQ)
Is phage therapy for asthma approved in Germany? There is currently no general approval in Germany for phages as a finished medicinal product for asthma. However, treatment is possible as part of an individual compassionate-use attempt (§ 13(2b) AMG), particularly when conventional antibiotic therapies fail due to resistance or intolerance.
How quickly does it work in bacterial worsening of asthma? In a bacterially caused exacerbation, an improvement in respiratory symptoms can often occur within 2 to 5 days. The phages multiply directly in the bronchi as long as their target bacteria are present, leading to a rapid reduction in inflammatory triggers.
Can phage therapy be used together with asthma inhalers or antibiotics? Yes, combining it with corticosteroid inhalers, bronchodilators, and antibiotics is generally possible without problems. Studies often show a synergistic effect, in which phages break up the bacterial protective layer (biofilm) and can even increase the effectiveness of accompanying antibiotics.
Why is a phagogram necessary before inhalation therapy? A phagogram is essential to test the match of the phages to the specific pathogen in the patient’s sputum. Because phages act in a highly selective manner, only this laboratory test ensures that the viruses used can effectively neutralize the disease-causing bacteria in the airways.

Great process, fast delivery!
"I placed a trial order. After having my first very good experiences with it after just a few days, I placed a second order on Sunday evening. It arrived on Tuesday. The process is very straightforward and delivery is very fast. I cannot say much about the effect yet. Another review will follow."Finally able to breathe freely again
"Somewhat unsure, I tried phages for the first time because of a persistent sinus infection. After just 4 days it was noticeably better and I can almost completely stop using the nasal spray. Great product, good price, and a helpful website."Found a solution
"Thank you for the product. I had a major problem with my throat and nose—Staphylococcus aerus bacteria, resistant to antibiotics. After a 10-day course, I felt much better. Two or three weeks later, I took Phagie again. It really improved a lot. After three months, during winter, I was neither completely ill nor completely well for a few weeks. I bought it again, took it again, and it helped again. While taking it, the improvement may not appear immediately. A fever spike is possible. But I am so glad that I found the solution to my problem. Stay healthy, everyone!!!!!"My wife after hospital surgery
"My wife after hospital surgery. She was infected with hospital-resistant bacteria; after five antibiotics, no success. Only with Phagen24 did we succeed!"Healthier
"Fast shipping. Well packaged. Then you need to read up a bit. I used the bacteriophages to treat my severe chronic sinus infection, which for years had repeatedly been treated with antibiotics. I inhaled 3x daily with an inhaler. After 3 days, my sinuses were noticeably clearer. They are now simply ventilated again when breathing. Haven’t had this for years. Wonderful! I will observe whether it lasts."Great process, fast delivery!
