What is Tarivid?
Tarivid (ofloxacin) is a second-generation fluoroquinolone antibiotic with broad-spectrum antibacterial activity. It is used to treat a range of bacterial infections, including urinary tract infections (UTIs), sexually transmitted infections caused by susceptible bacteria, and epididymo-orchitis.
Ofloxacin has been in clinical use since the 1980s and is recognised in European and WHO clinical guidelines as an effective antibiotic for specific sexual health indications. However, it is generally reserved for situations where first-line antibiotics are not appropriate, due to the class-specific safety considerations associated with fluoroquinolones.
How does Tarivid work?
Ofloxacin belongs to the fluoroquinolone class of antibiotics and kills bacteria through a mechanism that is distinct from other antibiotic classes:
- DNA gyrase and topoisomerase IV inhibition: Ofloxacin inhibits two bacterial enzymes — DNA gyrase (topoisomerase II) and topoisomerase IV — that are essential for bacterial DNA replication, transcription, repair, and recombination.
- DNA strand breaks: Inhibition of these enzymes causes irreversible double-strand breaks in bacterial DNA, leading to disruption of DNA structure and function.
- Bactericidal activity: The resulting DNA damage is lethal to the bacterium, making ofloxacin a bactericidal antibiotic (it kills bacteria rather than merely inhibiting growth).
- Broad gram-negative activity: Ofloxacin has strong activity against gram-negative bacteria (including Escherichia coli, Neisseria gonorrhoeae) and moderate activity against gram-positive organisms. Importantly for sexual health, it is also active against the intracellular pathogen Chlamydia trachomatis.
Levofloxacin: Levofloxacin is the L-isomer of ofloxacin and is essentially the active component. Levofloxacin has largely replaced ofloxacin in many markets due to a twice-daily dosing schedule becoming once-daily.
Who is Tarivid for?
In sexual health practice, ofloxacin is relevant for:
- Uncomplicated UTIs: Lower urinary tract infections caused by susceptible gram-negative organisms (e.g., E. coli), though fluoroquinolones are now reserved for cases where first-line agents are unsuitable due to resistance or allergy concerns
- Non-gonococcal urethritis (NGU): Alternative treatment option
- Chlamydia (Chlamydia trachomatis): 200–300 mg twice daily for 7 days — alternative to doxycycline or azithromycin
- Epididymo-orchitis: European STI guidelines include ofloxacin 200 mg twice daily for 14 days as an option for epididymo-orchitis likely caused by enteric organisms in older men (not suitable if gonorrhoea is suspected)
- Pelvic inflammatory disease (PID): Used in combination regimens including metronidazole
Ofloxacin is not appropriate for:
- Children and adolescents under 18 years (risk of cartilage damage — a fluoroquinolone class restriction)
- Pregnant or breastfeeding women
- Patients with a history of tendon disorders related to fluoroquinolone use
- Patients with QT prolongation or on QT-prolonging medicines
- Gonorrhoea — fluoroquinolone resistance in Neisseria gonorrhoeae is widespread in Europe; ofloxacin should not be used unless susceptibility is confirmed
Posologia
| Indicazione | Dose | Durata |
|---|---|---|
| Uncomplicated UTI | 200 mg twice daily | 3–7 days |
| Complicated UTI | 200 mg twice daily | 7–14 days |
| Chlamydia (alternative) | 200–300 mg twice daily | 7 days |
| NGU (alternative) | 200 mg twice daily | 7 days |
| Epididymo-orchitis (enteric organisms) | 200 mg twice daily | 14 days |
| PID (in combination) | 400 mg twice daily | 14 days |
Tarivid tablets can be taken with or without food. Take with adequate water. Avoid taking with antacids, iron, zinc, or calcium-rich products within 2 hours (reduced absorption).
Effetti collaterali
Fluoroquinolones have a specific safety profile that must be considered, including some class-specific risks not seen with other antibiotic classes.
Effetti collaterali comuni
- Nausea
- Diarrhoea
- Headache
- Dizziness
- Insomnia or sleep disturbance
- Photosensitivity (avoid sun exposure; use sunscreen)
Fluoroquinolone class-specific safety concerns
Tendinopathy and tendon rupture: Fluoroquinolones can cause inflammation and rupture of tendons, most commonly the Achilles tendon. Risk is higher in patients over 60 years, those taking systemic corticosteroids, and those with kidney, heart, or lung transplants. Stop treatment immediately if tendon pain, swelling, or inflammation develops.
Peripheral neuropathy: Fluoroquinolones can cause peripheral sensory neuropathy — tingling, burning, or numbness in the extremities. This may be long-lasting. Discontinue immediately if these symptoms develop.
Central nervous system effects: Dizziness, confusion, anxiety, tremors, and rarely seizures. Caution in patients with a history of seizures or CNS conditions.
QT prolongation: Ofloxacin can prolong the QT interval, increasing the risk of cardiac arrhythmias. Avoid in patients with known QT prolongation or on other QT-prolonging medicines.
Aortic aneurysm and dissection: An association between fluoroquinolone use and aortic aneurysm or dissection has been identified by the EMA. Avoid in patients with known aortic aneurysm or risk factors.
Hypoglycaemia and hyperglycaemia: Disturbances in blood sugar have been reported, particularly in diabetic patients taking antidiabetic medicines.
Tarivid vs alternative antibiotics for STI treatment
| Antibiotic | Chlamydia | UTI | NGU | Epididymo-orchitis | Notes |

Informazioni importanti sulla sicurezza
Non assuma Tarivid se Lei:
- Are under 18 years of age
- Are pregnant or breastfeeding
- Have previously had a tendon disorder caused by a fluoroquinolone antibiotic
- Have myasthenia gravis (risk of worsening)
- Have QT prolongation or are taking other QT-prolonging medicines

EMA regulatory note: The EMA has issued guidance restricting the use of fluoroquinolone antibiotics to situations where other antibiotics cannot be used, given the serious disabling and potentially permanent side effects (tendon, muscle, joint, and nervous system effects). A doctor will weigh these considerations when prescribing.

Frequently asked questions
- What is Tarivid (Ofloxacin) used for in sexual health?
- Tarivid (ofloxacin) is a fluoroquinolone antibiotic used to treat urinary tract infections (UTIs), non-gonococcal urethritis (NGU), chlamydia (as an alternative to first-line agents), epididymo-orchitis (testicular and epididymis inflammation often caused by STIs), and pelvic inflammatory disease (PID) as part of combination regimens.
- Is Ofloxacin still recommended for chlamydia?
- Ofloxacin is recognised as an effective alternative for treating Chlamydia trachomatis infection in patients who cannot take first-line agents (doxycycline or azithromycin). It requires a 7-day twice-daily course and is not used as a first-line choice due to the higher pill burden and fluoroquinolone-specific safety considerations compared to preferred alternatives.
- What are the most important side effects to be aware of with Tarivid?
- Fluoroquinolones including ofloxacin carry important safety warnings. Tendinopathy (tendon inflammation or rupture, particularly the Achilles tendon) is a class-specific risk, especially in older patients or those taking corticosteroids. Central nervous system effects (dizziness, insomnia, headache, rarely seizures) and QT prolongation (cardiac rhythm effects) are also recognised risks that must be discussed with your doctor.
- Should I avoid sunlight while taking Tarivid?
- Yes. Fluoroquinolones including ofloxacin can cause photosensitivity reactions — exaggerated sunburn-like reactions on sun-exposed skin. During treatment, apply sun protection and avoid prolonged exposure to sunlight or ultraviolet (UV) light, including tanning beds.
- Can I get Tarivid online in Europe?
- Tarivid (ofloxacin) è un farmaco soggetto a prescrizione medica in tutti gli stati membri dell'UE. È possibile accedere a it through online intermediary platforms that connect you with independent EU-registered doctors for a confidential health assessment and, if appropriate, a prescription.
