In daily life, bacterial infections such as pharyngitis, tonsillitis, bronchitis, cystitis, and urethritis can often delay recovery or lead to further complications if not properly treated.
Today, we’d like to introduce a commonly used broad-spectrum antibiotic in Japan — Doxycycline Hydrochloride Tablets (Vibramycin 50 mg). Developed by Pfizer Japan, this oral antibacterial medication is widely used in clinical practice.
1. Product Highlights
Developed by Pfizer Japan, this original prescription medication ensures reliable quality.
Each tablet contains 50 mg of Doxycycline Hydrochloride Hydrate, film-coated for improved taste and ease of swallowing.
It works by inhibiting bacterial protein synthesis, offering effectiveness against a wide range of pathogenic bacteria.

3. Precautions for Use

4. Suitable Users & Use Cases
You may consult a doctor about using this medication if you or a family member is experiencing:
Recurrent pharyngitis or tonsillitis
Respiratory infections such as bronchitis or pneumonia
Urinary or reproductive tract infections, such as cystitis, urethritis, or prostatitis
Secondary infections of the skin or soft tissue after injury
⚠️ Doxycycline is a prescription medication. Not all infections are appropriate for its use. Always consult a healthcare professional.
5. Friendly Reminders
Complete the full course of antibiotics as prescribed—do not stop early or adjust the dose on your own, to avoid resistance.
If symptoms do not improve or if adverse effects occur (e.g., rash, jaundice, gastrointestinal discomfort), stop use and seek medical attention immediately.
Maintain good hygiene habits—wash hands frequently, keep the mouth and respiratory tract clean, and avoid cross-infection.
Always purchase medication from reputable sources to avoid counterfeit or expired products.
In an environment where "illness enters through the mouth and bacteria spread easily," choosing the right antibiotic is essential to recovery.
Doxycycline Hydrochloride Tablets (Vibramycin 50 mg × 100 tablets) are trusted by physicians for their broad-spectrum efficacy, original formulation by Pfizer, and direct delivery from Japan.
But please always remember:
Even the best medicine should never be used blindly.
The right approach is to use it under proper medical guidance after a confirmed diagnosis.
