Cipro XR is the brand name for ciprofloxacin extended-release tablets, a once-daily fluoroquinolone antibiotic specifically approved for treating urinary tract infections (UTIs) and kidney infections (pyelonephritis) in adults aged 18 and older. The extended-release formulation delivers ciprofloxacin more slowly over 24 hours, allowing for convenient once-daily dosing.
Important 2026 note: Brand-name Cipro XR (Bayer) has been discontinued. Generic ciprofloxacin extended-release (ciprofloxacin ER) is still available from multiple manufacturers. Patients should ask for the generic by name at their pharmacy.
Cipro XR is available in two strengths: 500 mg (for uncomplicated UTIs, taken for 3 days) and 1000 mg (for complicated UTIs and pyelonephritis, taken for 7-14 days). It is not a controlled substance and can be prescribed by any licensed medical provider, including primary care physicians, nurse practitioners, physician assistants, and telehealth providers.

Cipro XR belongs to the fluoroquinolone class of antibiotics. It works by inhibiting two bacterial enzymes critical for DNA replication: DNA gyrase (topoisomerase II) and topoisomerase IV. By blocking these enzymes, ciprofloxacin traps them in a complex with bacterial DNA, causing DNA strand breaks that prevent bacteria from replicating and ultimately kill the infection.
Ciprofloxacin is particularly effective for urinary tract infections because it is primarily excreted by the kidneys and achieves very high concentrations in the urine — far above the minimum inhibitory concentration (MIC) for most common UTI-causing bacteria such as E. coli, Klebsiella, and Proteus mirabilis. It also penetrates kidney tissue well, making it effective for kidney infections.
The extended-release formulation uses a bilayer matrix that releases one portion of the drug quickly (for an immediate effect) and the rest slowly over 24 hours. This allows once-daily dosing while achieving a higher peak concentration (Cmax) than equivalent twice-daily immediate-release doses.
500 mg — extended-release tablet
Once daily for 3 days — for uncomplicated UTI (acute cystitis)
1000 mg — extended-release tablet
Once daily for 7-14 days — for complicated UTI or acute uncomplicated pyelonephritis. Reduce to 500 mg QD if CrCl ≤30 mL/min.
Cipro XR can be moderately challenging to find because brand-name Cipro XR (Bayer) has been discontinued. While generic ciprofloxacin extended-release is available from multiple manufacturers, not every retail pharmacy stocks it routinely. Many pharmacies carry only immediate-release ciprofloxacin tablets, which require twice-daily dosing. There is no active FDA-declared drug shortage of ciprofloxacin extended-release.
The most common patient frustration is asking for 'Cipro XR' by brand name and being told it's discontinued — which is true for the brand, but not for the generic. Patients should ask specifically for 'ciprofloxacin extended-release' or 'ciprofloxacin ER' and specify the strength (500 mg or 1000 mg). Independent pharmacies often have better sourcing flexibility than large chains.
If you're struggling to find ciprofloxacin ER at your local pharmacy, medfinder can call pharmacies near you to find which ones can fill your prescription — no hold music required.
Because Cipro XR (ciprofloxacin extended-release) is not a controlled substance, any licensed prescriber can write a prescription for it without special DEA authorization or scheduling restrictions. This includes medical doctors (MDs/DOs), nurse practitioners (NPs), physician assistants (PAs), and other licensed prescribers in all U.S. states.
Types of healthcare providers who commonly prescribe ciprofloxacin extended-release:
Primary care physicians (family medicine, internal medicine)
Urologists
OB-GYNs
Nurse practitioners (NPs) and physician assistants (PAs)
Urgent care providers
Infectious disease specialists (for complex or recurrent cases)
Telehealth is widely available for obtaining a Cipro XR prescription for uncomplicated UTIs. Platforms such as Teladoc, MDLive, AmWell, and UTI-specific telehealth services (Wisp, Nurx) can provide same-day electronic prescriptions for UTIs. For kidney infections with severe symptoms, an in-person visit is generally recommended.
No. Cipro XR (ciprofloxacin extended-release) is NOT a controlled substance and is not scheduled by the DEA. This means there are no special federal restrictions on prescribing it, no limits on the number of refills per prescription, and no requirement for a DEA license or special prescription pad. Any licensed prescriber — including nurse practitioners and physician assistants in most states — can prescribe it freely.
Telehealth providers can also prescribe ciprofloxacin electronically without any special restrictions, making it convenient for patients seeking treatment for UTIs via online platforms. Typical refill limits depend on the antibiotic course length (usually 3-14 days), not controlled substance regulations.
Common side effects (occurring in ≥2% of patients) include:
Nausea
Headache
Dizziness
Diarrhea
Vomiting
Vaginal yeast infection (vaginal moniliasis)
Cipro XR carries an FDA Black Box Warning for potentially disabling and irreversible serious side effects:
Tendinitis and tendon rupture (especially Achilles tendon; risk elevated in patients >60, on corticosteroids, or post-transplant)
Peripheral neuropathy (numbness, tingling, burning — may be permanent)
CNS effects (seizures, psychosis, hallucinations, depression, suicidal thoughts)
Aortic aneurysm or dissection (rare but potentially fatal)
Exacerbation of myasthenia gravis
QT prolongation and cardiac arrhythmias
Severe allergic reactions including anaphylaxis
C. difficile-associated diarrhea (watery or bloody diarrhea)

Trimethoprim-Sulfamethoxazole (Bactrim DS)
First-line for uncomplicated UTIs per IDSA guidelines. Very affordable ($4-$15). Effective against E. coli, Proteus. Avoid with sulfa allergy or local resistance >20%.
Nitrofurantoin (Macrobid)
First-line for uncomplicated lower UTIs only. NOT appropriate for kidney infections. Affordable, fewer serious side effects than fluoroquinolones. Avoid if eGFR <30.
Levofloxacin (Levaquin)
Fluoroquinolone — same drug class as Cipro XR with same Black Box Warning. Comparable efficacy for UTI and pyelonephritis with once-daily dosing. Good option if specifically switching away from ciprofloxacin due to availability.
Fosfomycin (Monurol)
Single-dose oral antibiotic for uncomplicated lower UTIs. Convenient, good safety profile, lower resistance rates. More expensive ($50-$80 without insurance). Not for kidney infections.
Prefer Cipro XR? We can find it.
Tizanidine (Zanaflex)
majorCONTRAINDICATED. Ciprofloxacin inhibits CYP1A2, dramatically increasing tizanidine levels. Risk of severe hypotension and excessive sedation.
Theophylline
majorCiprofloxacin reduces theophylline clearance via CYP1A2 inhibition. Monitor theophylline levels; reduce dose if necessary. Risk of toxicity including seizures.
Warfarin (Coumadin)
majorEnhanced anticoagulant effect. Monitor INR closely during and after ciprofloxacin course. Warfarin dose may require adjustment.
Antacids (Mg/Al/Ca)
majorSignificantly reduce ciprofloxacin absorption. Take antacids at least 2 hours before or 6 hours after Cipro XR.
Iron, Zinc, Calcium supplements
moderateReduce ciprofloxacin absorption. Same 2-hour before / 6-hour after timing rule applies.
NSAIDs (ibuprofen, naproxen)
moderateIncreased risk of CNS stimulation and seizures when combined with fluoroquinolones.
QT-prolonging drugs (antiarrhythmics, antipsychotics)
majorAdditive QT prolongation risk. Use caution and consider ECG monitoring.
Sulfonylureas (glyburide, glipizide)
moderateMay worsen hypoglycemia. Monitor blood glucose more frequently.
Caffeine
minorCiprofloxacin reduces caffeine clearance. Patients may experience stronger/prolonged effects from caffeine consumption.
Cipro XR (ciprofloxacin extended-release) is an effective once-daily antibiotic for UTIs and kidney infections, but patients in 2026 face a practical challenge: brand-name Cipro XR has been discontinued. Generic ciprofloxacin ER remains available but requires knowing the right name to ask for — and knowing which pharmacies stock it.
On the clinical side, the FDA's Black Box Warning on fluoroquinolones means ciprofloxacin ER should be reserved for UTIs where safer alternatives (TMP-SMX, nitrofurantoin) are not appropriate. For patients who do need it, it's affordable and effective — but you may need to shop around a bit to fill it.
If you're struggling to find ciprofloxacin ER in stock, medfinder can do the pharmacy calling for you — saving time and frustration while you focus on getting better.
