Ciplox is a ciprofloxacin antibiotic. South Africa’s medicine registry lists it as Ciploxx, with a double x, at 250 mg and 500 mg — so check the exact spelling on your pack. It is a prescription antibiotic for certain bacterial infections, particularly urinary, prostate, gut and bone infections.
What is Ciplox?
Check the spelling on your pack. The South African Medicine Price Registry lists Ciploxx — with two x’s — and returns nothing for “Ciplox” with one. The strengths people search for (“Ciplox 500”) match the registered Ciploxx 500 exactly, so these are almost certainly the same product written two ways. If your pack differs from what is described here, take it to a pharmacist rather than assuming.
The registered product is Schedule 4 — prescription-only:
| Product | Contains |
|---|---|
| Ciploxx 250 | Ciprofloxacin 250 mg tablet |
| Ciploxx 500 | Ciprofloxacin 500 mg tablet |
A data note: some listings show ipratropium bromide alongside ciprofloxacin for the 250 mg tablet. Ipratropium is an inhaled asthma medicine measured in mg/2.5 ml — a nebuliser unit that makes no sense on a tablet — and the 500 mg entry lists ciprofloxacin alone. This is a database error, not a real combination. See the Ciploxx guide for more.
Ciprofloxacin is a fluoroquinolone antibiotic. It blocks two bacterial enzymes — DNA gyrase and topoisomerase IV — that bacteria need to copy and repair their DNA. Without them the bacterium cannot divide and dies. Human cells do not use these enzymes in the same way, making the drug selective.
Ciprofloxacin is a reserved antibiotic, not a general-purpose one. Guidelines increasingly restrict fluoroquinolones to situations where other antibiotics are unsuitable — not out of excess caution, but because this class carries a distinctive set of uncommon but serious side effects affecting tendons, nerves, the aorta and mental state.
What is Ciplox commonly used for?
A doctor may prescribe ciprofloxacin for:
- Urinary tract infections, including complicated infections and some kidney infections.
- Prostate infections, where ciprofloxacin penetrates tissue many antibiotics reach poorly.
- Gastrointestinal infections, including some bacterial gastroenteritis and typhoid fever.
- Bone and joint infections.
- Skin and soft-tissue infections caused by susceptible bacteria.
- Certain respiratory infections, where the specific organism calls for it.
- Some eye and ear infections, though these usually use drops.
It has no effect on viral illness. Colds, flu, most sore throats and most coughs are viral, and an antibiotic will not shorten them.
How Ciplox fits into this medicine category
| Group | Examples | Typical role |
|---|---|---|
| Fluoroquinolones | Ciprofloxacin (Ciploxx) | Urinary, prostate, gut, bone infections; reserved |
| Penicillins | Amoxicillin, flucloxacillin | Common first-line choices |
| Cephalosporins | Cefalexin | Skin, throat, urinary infections |
| Macrolides | Azithromycin | Chest infections, penicillin allergy |
| Nitroimidazoles | Metronidazole | Anaerobic and some parasitic infections |
| Nitrofurans | Nitrofurantoin | Uncomplicated urinary infections; often preferred |
For a simple, uncomplicated bladder infection, nitrofurantoin is usually preferred over ciprofloxacin — narrower, effective, and without the fluoroquinolone risks. See the antibiotics and antimicrobials hub.
What to check before using Ciplox
Separate it from calcium, magnesium, iron and zinc. This matters more with ciprofloxacin than with most antibiotics. Dairy products, antacids and mineral supplements bind ciprofloxacin in the gut and can prevent it being absorbed — a common reason treatment fails. Leave several hours between them.
Complete the full course as prescribed.
Tell your doctor or pharmacist if you:
- Have had a reaction to any quinolone antibiotic before.
- Have tendon problems, or previous tendonitis on a quinolone.
- Have kidney disease, which may change the dose.
- Have epilepsy or a seizure disorder.
- Have myasthenia gravis — ciprofloxacin can worsen it significantly.
- Have a heart rhythm disorder, or take medicines affecting the QT interval.
- Have an aortic aneurysm, a condition affecting the aorta, or a family history of one.
- Have a history of depression or psychiatric illness.
- Are pregnant or breastfeeding.
- Take warfarin, theophylline, tizanidine, methotrexate, corticosteroids such as prednisone — which add to tendon risk — or an NSAID.
- Are giving it to a child or teenager, where quinolones are used only in specific circumstances.
Drink plenty of water, take doses at evenly spaced times, and use sun protection — ciprofloxacin makes skin more sensitive to sunlight.
Possible cautions and when to ask a pharmacist or doctor
Common effects are nausea, diarrhoea, abdominal discomfort, headache and dizziness.
Stop and contact a doctor promptly if you develop:
- Pain, swelling or inflammation in a tendon — the Achilles especially. Tendon rupture can occur, risk is higher in older people and those taking steroids, and it can happen even weeks after stopping. Rest the limb and seek advice rather than exercising through it.
- Sudden severe pain in the chest, abdomen or back — seek emergency care.
- Pins and needles, numbness, burning or weakness in the hands or feet, which can be long-lasting.
- Confusion, hallucinations, marked anxiety, depression or suicidal thoughts.
- A seizure.
- Severe or bloody diarrhoea, during or after the course — possible C. difficile infection.
- Yellowing of the eyes or skin.
- Swelling of the face, lips or tongue, or difficulty breathing.
- A spreading rash, blistering or peeling skin.
- Palpitations or fainting.
- Vision changes, or joint pain and swelling.
Be cautious with intense exercise while taking it, given the tendon risk.
Contact your doctor if symptoms do not improve after a few days, or if they worsen at any point.
For a urinary infection, seek prompt medical attention if you develop fever, chills, back or flank pain, or feel generally unwell — that suggests the infection has reached the kidneys and needs urgent treatment.

Frequently asked questions
What is Ciplox 500 used for? Bacterial infections where ciprofloxacin is appropriate — commonly urinary tract, prostate, gut, bone and certain skin infections. It is prescription-only.
Is Ciplox the same as Ciploxx? The registry lists Ciploxx with two x’s at matching strengths, so they are almost certainly the same product written two ways. Check your pack, and ask a pharmacist if it differs.
Is it an antibiotic? Yes — ciprofloxacin, a fluoroquinolone antibiotic.
Will it help flu or a cold? No. Those are viral infections and antibiotics have no effect on them.
Why must I avoid dairy and antacids around it? Calcium, magnesium, iron and zinc bind ciprofloxacin in the gut and stop it being absorbed. Separate them by several hours.
Can I exercise while taking it? Be cautious with intense exercise because of the tendon risk. Stop and seek advice at any tendon pain or swelling.
Does it contain ipratropium? No. Ipratropium appearing in some listings is a database error — the unit given is a nebuliser measure, not a tablet one.
Can I stop once I feel better? No. Finish the prescribed course unless your doctor tells you otherwise.
