Doxycycline (Vibramycin Generic) – Complete Product Information

What is Doxycycline?

Doxycycline is a prescription antibiotic that belongs to the tetracycline class of medications. It is FDA-approved to treat a wide range of bacterial infections, including respiratory infections, skin infections (such as acne), urinary tract infections, and certain sexually transmitted infections. It is also used to prevent malaria. Common brand names include Vibramycin, Oracea, and Doryx.

Doxycycline works by inhibiting bacterial protein synthesis, which prevents bacteria from growing and multiplying. It is effective against a broad spectrum of bacteria and is often prescribed when other antibiotics are not suitable.

What is Doxycycline Used For?

According to the FDA, doxycycline is approved to treat:

• ✔️ Respiratory tract infections – including pneumonia and bronchitis caused by susceptible bacteria.
• ✔️ Acne and skin infections – reduces inflammation and bacterial growth.
• ✔️ Urinary tract infections – treats certain bacterial UTIs.
• ✔️ Sexually transmitted infections – including chlamydia and gonorrhea.
• ✔️ Malaria prevention – for travelers to certain regions.
• ✔️ Rosacea – reduces inflammation associated with this skin condition.

Doctors may also prescribe it off-label for other conditions, including Lyme disease and certain eye infections. Always follow your prescriber's instructions.

Available Dosages and Forms

Doxycycline is available as oral capsules, tablets, and oral suspension:

• Capsules: 50 mg, 75 mg, 100 mg, 150 mg
• Tablets: 50 mg, 75 mg, 100 mg, 150 mg
• Oral suspension: 25 mg/5 mL

Generic doxycycline is available in the same strengths and is equally effective, usually at a lower cost.

Brand Vibramycin vs Generic Doxycycline

Both contain the same active ingredient and meet the same FDA standards for quality, safety, and effectiveness. The only significant difference is price: generic doxycycline is typically much less expensive. Most insurance plans prefer or require generics.

When comparing prices, you may see both options. Choose the one that best fits your budget and prescription.

How to Take Doxycycline Safely

Always follow your healthcare provider's instructions. Doxycycline is usually taken once or twice daily with plenty of water. It is important to complete the full course, even if you feel better.

1. Take doxycycline with a full glass of water to reduce the risk of irritation to the esophagus.
2. Take it while sitting or standing, and do not lie down for at least 30 minutes after taking.
3. If stomach upset occurs, take it with food or milk, unless your doctor tells you otherwise.
4. Do not stop taking it early, even if symptoms improve.
5. Avoid prolonged sun exposure, as doxycycline can increase sun sensitivity.

• Nausea or vomiting
• Diarrhea
• Stomach upset
• Increased sensitivity to sunlight
• Loss of appetite
• Vaginal itching or discharge
