🧬 Understanding Bacteriophage Therapy

What are bacteriophages?

Bacteriophages (or "phages") are natural viruses that specifically target and destroy harmful bacteria. They're completely harmless to human cells and only attack the specific bacteria they're designed for. Think of them as precision-guided antibiotics from nature.

How do bacteriophages work?

Bacteriophages attach to specific bacteria, inject their genetic material, and multiply inside the bacterial cell until it bursts. This process destroys the harmful bacteria while leaving your healthy cells completely untouched. Unlike antibiotics that affect many types of bacteria, phages are highly specific.

Are bacteriophages safe?

Yes. Bacteriophages have been used safely for over 100 years, particularly in Eastern Europe. The manufacturer reports no contraindications. They can even be used alongside antibiotics if needed. However, always consult with a qualified healthcare professional before starting any treatment.

What's the difference between bacteriophages and antibiotics?

Antibiotics are chemical compounds that kill many types of bacteria (including beneficial ones). Bacteriophages are natural viruses that target only specific harmful bacteria. Phages can work against antibiotic-resistant bacteria and don't harm your beneficial gut bacteria.

Can bacteriophages help with antibiotic-resistant infections?

Yes, this is one of the key advantages of bacteriophage therapy. Because phages use a completely different mechanism than antibiotics, they can be effective against bacteria that have developed antibiotic resistance.


🎯 Choosing the Right Bacteriophage Product

Which bacteriophage product do I need?

The right bacteriophage depends on which bacteria is causing your infection. Our main products include:

  • PYO Bacteriophage - targets Staphylococcus aureus, Streptococcus, E. coli, Pseudomonas aeruginosa, and Proteus species
  • SES Bacteriophage - for specific bacterial strains
  • Fersisi Bacteriophage - specialized applications

We strongly recommend laboratory analysis before ordering to identify your specific bacteria and ensure you get the most effective phage. Start bacteriophage analysis →

What is the PYO Bacteriophage Treatment Course (6 Boxes)?

This is our complete treatment package containing 6 identical boxes of PYO bacteriophage. It's designed for confirmed cases where PYO is the appropriate treatment, providing continuity and predictable supply throughout your full treatment course. Each box contains the same high-quality, lab-tested product.

How long does a treatment course typically last?

Treatment duration varies based on the condition and application method, typically ranging from 5-20 days. The 6-box course is designed to provide sufficient supply for most standard treatment protocols. Your healthcare provider will determine the exact duration for your specific case.

Do I need a prescription?

No prescription is required to order bacteriophage products from us. However, we strongly recommend working with a qualified healthcare professional who can guide proper usage, dosage, and monitor your progress.

Should I get laboratory analysis first?

Yes, we highly recommend it. Laboratory analysis identifies exactly which bacteria is causing your infection, ensuring you order the right bacteriophage product. This saves time, money, and increases treatment effectiveness. Learn about our analysis service →

❄️ Storage & Handling

How should I store bacteriophages?

Store all bacteriophage products in a refrigerator at +2°C to +8°C (36°F to 46°F). This is the temperature of a standard household refrigerator. Do not freeze. Keep away from light.

What is the shelf life?

Unopened bacteriophage products have a shelf life of 12 months when stored properly at +2°C to +8°C. Always check the expiration date on your product.

How long can bacteriophages stay at room temperature?

Bacteriophages should be returned to refrigeration as soon as possible. Brief periods at room temperature (during application) are acceptable, but prolonged exposure to warm temperatures can reduce effectiveness. Never leave products out of refrigeration for extended periods.

What should I do after opening a container?

Use immediately after opening. Do not store opened containers. Once opened, the product should be used for that application session and any remaining product should be discarded. This maintains sterility and effectiveness.

How can I tell if the product is still good?

Before each use, visually inspect the liquid. It should be clear and transparent with white or yellow coloration. Do not use if:

  • The liquid is cloudy
  • There is sediment or particles
  • The container is damaged
  • The product is past its expiration date

💊 Usage & Dosage

How do I use bacteriophages?

Application methods vary depending on the infection location. Common methods include:

  • Oral: Drinking the liquid (typically 1 hour before meals)
  • Topical: Applying to wounds or skin with phage-soaked dressings
  • Rectal: Enema administration
  • Cavity application: Into wound cavities, bladder, or other affected areas
  • Eye drops: For ocular infections

Always shake the ampoule/bottle before use. Your healthcare provider will determine the best application method for your specific condition.

What is the typical dosage?

Dosage varies by age, condition, and application method. General guidelines for oral use:

  • Infants (0-6 months): 5 ml once daily
  • Infants (6-12 months): 5 ml twice daily
  • Children (1-3 years): 5 ml three times daily
  • Children (3-8 years): 10 ml 2-3 times daily
  • Children & adults (8+ years): 20 ml 2-3 times daily

These are general informational guidelines. Your healthcare provider will determine the exact dosage for your specific situation.

When should I take bacteriophages?

For oral use, bacteriophages are typically taken 1 hour before meals (for children over 3 and adults) or 30 minutes before feeding (for infants). This timing helps maximize effectiveness. For children over 3 and adults, drinking mineral water or a mild alkaline solution before taking the phage may be recommended.

Can I use bacteriophages with antibiotics?

Yes, bacteriophage use does not exclude other therapeutic approaches, including antibiotics. Many practitioners use them together. However, always inform your healthcare provider about all treatments you're using.

How quickly do bacteriophages work?

Response time varies by individual and condition. Some people notice improvement within a few days, while others may take 1-2 weeks. Early-stage application generally provides the highest effectiveness. Continue the full treatment course as directed, even if symptoms improve.

What if I miss a dose?

Take the missed dose as soon as you remember, unless it's almost time for your next dose. Don't double up doses. Consistency is important for effectiveness, so try to maintain your regular schedule.


⚕️ Safety & Side Effects

Are there any side effects?

Bacteriophages are generally very well tolerated. The manufacturer reports no contraindications. Some people may experience mild, temporary digestive changes when starting oral phage therapy as harmful bacteria are eliminated. Serious side effects are extremely rare.

Who should not use bacteriophages?

The manufacturer reports no specific contraindications. However, pregnant women, nursing mothers, and people with compromised immune systems should consult their healthcare provider before starting any new treatment.

Can children use bacteriophages?

Yes, bacteriophages can be used safely in children, including infants. Dosage is adjusted based on age (see dosage guidelines above). Always work with a pediatrician or qualified healthcare provider for children's treatment.
