Understanding O2 Tablet and Its Composition
O2 Tablet is a prescription medication that combines two powerful antimicrobial agents: Ofloxacin and Ornidazole. This dual formulation allows it to combat infections caused by both bacteria and parasites, making it particularly effective for mixed infections. It is manufactured by Medley Pharmaceuticals Ltd. and is available in different dosage forms, including tablets and suspensions.
How O2 Tablet Works
The combined action of Ofloxacin and Ornidazole provides a broad-spectrum attack against harmful pathogens.
- Ofloxacin (Antibiotic): This is a second-generation fluoroquinolone antibiotic. It works by inhibiting a bacterial enzyme called DNA gyrase, which is crucial for the replication, repair, and transcription of bacterial DNA. By blocking this process, Ofloxacin prevents the bacteria from multiplying and growing, ultimately killing them.
- Ornidazole (Antiprotozoal): A nitroimidazole derivative, Ornidazole targets and kills susceptible microorganisms, including protozoa and anaerobic bacteria, by interfering with their DNA functioning and protein synthesis.
Primary Medical Uses of O2 Tablet
The combination of Ofloxacin and Ornidazole makes O2 Tablet suitable for treating a variety of infections where a mixed bacterial and parasitic etiology is suspected.
- Gastrointestinal Infections: The tablet is commonly prescribed for adults suffering from acute diarrhea and dysentery, especially when caused by mixed infections. This includes cases of food poisoning and other stomach or intestinal infections.
- Urinary Tract Infections (UTIs): O2 Tablet can be used to treat UTIs caused by susceptible bacteria.
- Gynecological Infections: It is effective in treating various gynecological infections.
- Respiratory Tract Infections: The medication helps in treating bacterial respiratory infections like bronchitis and pneumonia.
- Skin and Soft Tissue Infections: O2 Tablet is also utilized to treat bacterial infections affecting the skin and underlying soft tissues.
- Intra-abdominal Infections: Infections within the abdominal cavity can also be treated with O2 Tablet.
Important Considerations and Precautions
Before taking O2 Tablet, it is crucial to discuss your medical history with a doctor, as certain conditions and lifestyle factors can affect its safety and efficacy.
Who Should Not Take O2 Tablet?
O2 Tablet is contraindicated in individuals with:
- Allergies to Ofloxacin, Ornidazole, or any quinolone/nitroimidazole antibiotics.
- A history of seizures or epilepsy.
- A history of tendinitis or tendon rupture associated with quinolone use.
- Myasthenia gravis, as it can worsen muscle weakness.
- The first trimester of pregnancy and while breastfeeding.
Drug and Food Interactions
O2 Tablet can interact with other substances, potentially leading to adverse effects or reduced efficacy. Key interactions include:
- Antacids and Supplements: Products containing magnesium, aluminum, calcium, or iron can reduce the absorption of Ofloxacin. They should be taken at least two hours before or after O2 Tablet.
- Blood Thinners: Concomitant use with blood thinners like warfarin can increase the risk of bleeding.
- Alcohol: Avoid alcohol consumption as it can worsen side effects like dizziness and drowsiness.

| Infection Types | Mixed infections like diarrhea, UTIs, respiratory, skin infections. | Single-agent treatment for UTIs, respiratory infections, and more. | Used for parasitic infections, anaerobic bacterial infections, and specific dental infections. |
| Mechanism of Action | Dual-action: Inhibits DNA gyrase and interferes with DNA functioning. | Inhibits DNA gyrase. | Interferes with bacterial/protozoal DNA functioning. |
| Potential Side Effects | Nausea, vomiting, dizziness, headache, tendon issues. | Nausea, diarrhea, headache, lightheadedness, tendon issues. | Nausea, metallic taste, headache, dizziness, peripheral neuropathy. |
Dosage and Administration
O2 Tablet should be taken as directed by a healthcare professional.
- Dosage: The recommended dose is typically one tablet twice daily for adults, but the exact dose and duration depend on the type and severity of the infection.
- Administration: It can be taken with or without food to minimize stomach discomfort. Swallow the tablet whole with a glass of water; do not crush, break, or chew it.
- Duration: Complete the entire course of treatment, even if symptoms improve, to prevent antibiotic resistance and ensure the infection is fully eradicated.
Conclusion
O2 Tablet, combining Ofloxacin and Ornidazole, is a highly effective medication for treating a wide array of mixed bacterial and parasitic infections. It offers a powerful dual-action approach, making it a reliable choice for conditions like diarrhea, dysentery, and various gastrointestinal, urinary, and respiratory infections. However, its use requires careful consideration of precautions and potential side effects, especially in patients with pre-existing conditions. Always follow a doctor's prescription and complete the full course of treatment to ensure effectiveness and minimize the risk of antibiotic resistance.
