Drug interactions

Moderate drug interactions

Moderate:

ciprofloxacin primaquine

Applies to: Cipro XR (ciprofloxacin) and primaquine

Using ciprofloxacin together with primaquine can increase the risk of an irregular heart rhythm that may be serious and potentially life-threatening, although it is a relatively rare side effect.

You may be more susceptible if you have:

  • a heart condition called congenital long QT syndrome
  • other cardiac diseases
  • conduction abnormalities
  • electrolyte disturbances (for example, magnesium or potassium loss due to severe or prolonged diarrhea or vomiting)

Talk to your doctor if you have any questions or concerns.

You should seek immediate medical attention if you develop sudden dizziness, lightheadedness, fainting, shortness of breath, or heart palpitations during treatment with these medications, whether together or alone.

It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Food/lifestyle interactions

Moderate food/lifestyle interactions

Moderate:

ciprofloxacin Food/Lifestyle

Applies to: Cipro XR (ciprofloxacin)

Do not take ciprofloxacin with dairy products such as milk or yogurt, or with calcium-fortified foods (e.G., cereal, juice). You may eat or drink dairy products or calcium-fortified foods with a regular meal, but do not use them alone when taking ciprofloxacin. They could make the medication less effective.

When ciprofloxacin tablets are given with enteral (tube) feedings, ciprofloxacin may not work as well. You could interrupt the feeding for 1 hour before and 2 hours after the ciprofloxacin dose, or your doctor may decide to switch to a different treatment.

Ciprofloxacin oral suspension should not be given via nasogastric tubes or feeding tubes.

It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Moderate:

ciprofloxacin multivitamins with minerals

Applies to: Cipro XR (ciprofloxacin)

In general, multivitamins with minerals and ciprofloxacin should not be taken orally at the same time.

Products that contain aluminum, calcium, iron, magnesium, zinc and/or other minerals may interfere with the absorption of ciprofloxacin into the bloodstream and reduce its effectiveness in treating your infection.

If possible, it may be best to avoid taking multivitamins with minerals while you are being treated with ciprofloxacin. Otherwise, you should separate their dosing times by as much as possible, usually at least 2 to 4 hours.

Talk to your healthcare provider if you are unsure whether your medications contain something that could potentially interact or if you have questions on how to take this or other medications you are prescribed.

It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Moderate:

ciprofloxacin Caffeine

Applies to: Cipro XR (ciprofloxacin)

Using caffeine together with ciprofloxacin may increase the effects of caffeine.

Contact your doctor if you experience:

  • headache
  • tremor
  • restlessness
  • nervousness
  • insomnia
  • increased blood pressure or heart rate

If your doctor does prescribe these medications together, you may need a dose adjustment or special test to safely use both medications.

It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Disease interactions

27 potential interactions Applies to: 25 conditions, including Heart Failure, Rheumatoid Arthritis, Peripheral Neuropathy, Diarrhea, and Arrhythmia.

Abnormal Electrocardiogram

Major:

Cipro XR

The ciprofloxacin in Cipro XR has a major potential interaction with Abnormal Electrocardiogram.

Quinolones have been reported to prolong the QT interval of the electrocardiogram in some patients. QT prolongation may potentiate the risk of ventricular arrhythmias including ventricular tachycardia, ventricular fibrillation, and torsade de pointes. The risk appears to be greatest with grepafloxacin and sparfloxacin (both are no longer marketed in the U.S.), although cardiovascular morbidity and mortality attributable to QT prolongation have also been reported rarely with others like gatifloxacin, levofloxacin, ciprofloxacin, and ofloxacin. Reported cases have primarily occurred in patients with advanced age, cardiac disease, electrolyte disturbances, and/or underlying medical problems for which they were receiving concomitant medications known to prolong the QT interval. Therapy with quinolones should be avoided in patients with known QT prolongation and/or uncorrected electrolyte disorders (hypokalemia or hypomagnesemia) and in patients treated concomitantly with class IA or III antiarrhythmic agents. Cautious use with ECG monitoring is advised in patients with other proarrhythmic conditions such as clinically significant bradycardia, congestive heart failure, acute myocardial ischemia, and atrial fibrillation. As QT prolongation may be a concentration-dependent effect, it is important that the recommended dosages or infusion rates of these drugs not be exceeded, particularly in patients with renal and/or hepatic impairment.

Anemia

Major:

primaquine

Primaquine has a major potential interaction with Anemia.

The use of primaquine is contraindicated in acutely ill patients suffering from systemic disease manifested by tendency to granulocytopenia, such as rheumatoid arthritis and lupus erythematosus. Primaquine has been reported to cause hematologic toxicity such as bone marrow depression, anemia, and leukopenia. Therapy with primaquine should be administered cautiously in patients with preexisting bone marrow depression or leukopenia. Since large doses of primaquine may increase the risk of leukopenia, the recommended dosage (15 mg base daily for 14 days in adults) should not be exceeded. Close monitoring is recommended if primaquine is prescribed to patients who have shown a previous idiosyncrasy to primaquine as manifested by leukopenia, hemolytic anemia, or methemoglobinemia. Blood cell counts should be performed regularly. Primaquine therapy should be discontinued immediately if there is a sudden decrease in leukocyte count.

Arrhythmia

Major:

Cipro XR

The ciprofloxacin in Cipro XR has a major potential interaction with Arrhythmia.

Quinolones have been reported to prolong the QT interval of the electrocardiogram in some patients. QT prolongation may potentiate the risk of ventricular arrhythmias including ventricular tachycardia, ventricular fibrillation, and torsade de pointes. The risk appears to be greatest with grepafloxacin and sparfloxacin (both are no longer marketed in the U.S.), although cardiovascular morbidity and mortality attributable to QT prolongation have also been reported rarely with others like gatifloxacin, levofloxacin, ciprofloxacin, and ofloxacin. Reported cases have primarily occurred in patients with advanced age, cardiac disease, electrolyte disturbances, and/or underlying medical problems for which they were receiving concomitant medications known to prolong the QT interval. Therapy with quinolones should be avoided in patients with known QT prolongation and/or uncorrected electrolyte disorders (hypokalemia or hypomagnesemia) and in patients treated concomitantly with class IA or III antiarrhythmic agents. Cautious use with ECG monitoring is advised in patients with other proarrhythmic conditions such as clinically significant bradycardia, congestive heart failure, acute myocardial ischemia, and atrial fibrillation. As QT prolongation may be a concentration-dependent effect, it is important that the recommended dosages or infusion rates of these drugs not be exceeded, particularly in patients with renal and/or hepatic impairment.

Central Nervous System Disorders

Major:

Cipro XR

The ciprofloxacin in Cipro XR has a major potential interaction with Central Nervous System Disorders.

Quinolones may cause CNS stimulation manifested as tremors, agitation, restlessness, anxiety, confusion, hallucinations, paranoia, insomnia, toxic psychosis, and/or seizures. Benign intracranial hypertension has also been reported. Therapy with quinolones should be administered cautiously in patients with or predisposed to seizures or other CNS abnormalities. In addition, these patients should be advised to avoid the consumption of caffeine-containing products during therapy with some quinolones, most notably ciprofloxacin, enoxacin, and cinoxacin, since these agents can substantially reduce the clearance of caffeine and other methylxanthines, potentially resulting in severe CNS reactions.

Dehydration

Moderate:

Cipro XR

The ciprofloxacin in Cipro XR has a moderate potential interaction with Dehydration.

Crystalluria has been reported rarely during quinolone therapy. Although it is not expected to occur under normal circumstances with usual recommended dosages, patients who are dehydrated (e.g., due to severe diarrhea or vomiting) may be at increased risk and should be encouraged to consume additional amounts of liquid or given intravenous fluid to ensure an adequate urinary output. Alkalinity of the urine should be avoided, since it may also increase the risk of crystalluria. Renal function tests should be performed periodically during prolonged therapy (> 2 weeks).

Diabetes Mellitus

Moderate:

Cipro XR

The ciprofloxacin in Cipro XR has a moderate potential interaction with Diabetes Mellitus.

The use of certain quinolones has been associated with disturbances in blood glucose homeostasis possibly stemming from effects on pancreatic beta cell ATP-sensitive potassium channels that regulate insulin secretion. Hypoglycemia and, less frequently, hyperglycemia have been reported, although the latter may also occur due to infection alone. Hypoglycemia has usually occurred in patients with diabetes receiving concomitant oral hypoglycemic agents and/or insulin. Administration of ciprofloxacin, levofloxacin, norfloxacin, and especially gatifloxacin in patients treated with sulfonylureas or other oral hypoglycemic agents has resulted in severe, refractory hypoglycemia and hypoglycemic coma. Elderly patients and patients with reduced renal function are particularly susceptible. Blood glucose should be monitored more closely whenever quinolones are prescribed to patients with diabetes. Gatifloxacin has been known to cause hypoglycemic episodes generally within the first 3 days of therapy and sometimes even after the first dose, while hyperglycemia usually occurs 4 to 10 days after initiation of therapy. Patients should be counseled to recognize symptoms of hypoglycemia such as headache, dizziness, drowsiness, nausea, tremor, weakness, hunger, excessive perspiration, and palpitations. If hypo- or hyperglycemia occur during quinolone therapy, patients should initiate appropriate remedial therapy immediately, discontinue the antibiotic, and contact their physician.

Diarrhea

Moderate:

Cipro XR

The ciprofloxacin in Cipro XR has a moderate potential interaction with Diarrhea.

Crystalluria has been reported rarely during quinolone therapy. Although it is not expected to occur under normal circumstances with usual recommended dosages, patients who are dehydrated (e.g., due to severe diarrhea or vomiting) may be at increased risk and should be encouraged to consume additional amounts of liquid or given intravenous fluid to ensure an adequate urinary output. Alkalinity of the urine should be avoided, since it may also increase the risk of crystalluria. Renal function tests should be performed periodically during prolonged therapy (> 2 weeks).

Electrolyte Abnormalities

Major:

Cipro XR

As QT prolongation may be a concentration-dependent effect, it is important that the recommended dosages or infusion rates of these drugs not be exceeded, particularly in patients with renal and/or hepatic impairment.

G-6-PD Deficiency

Major:

primaquine

Primaquine has a major potential interaction with G-6-PD Deficiency.

Hemolysis, hemolytic anemia, and methemoglobinemia have been reported during use of primaquine in patients with glucose-6-phosphate dehydrogenase (G-6-PD) deficiency or nicotinamide adenine dinucleotide (NADH)-methemoglobin reductase deficiency. Therapy with primaquine should be administered cautiously in these patients. Since large doses of primaquine may increase the risk of hemolytic reactions, the recommended dosage (15 mg base daily for 14 days in adults) should not be exceeded. Close monitoring is recommended if primaquine is prescribed to patients who have shown a previous idiosyncrasy to primaquine or that have family or personal history of favism. Blood cell counts and hemoglobin determinations should be performed regularly. Primaquine therapy should be discontinued immediately if signs suggestive of hemolytic anemia occur, such as marked darkening of the urine or sudden decrease in hemoglobin concentration or erythrocytic count.

Heart Failure

Major:

Cipro XR

The ciprofloxacin in Cipro XR has a major potential interaction with Heart Failure.

Quinolones have been reported to prolong the QT interval of the electrocardiogram in some patients.

Noninfectious Colitis

Major:

Cipro XR

The ciprofloxacin in Cipro XR has a major potential interaction with Noninfectious Colitis.

Clostridioides difficile-associated diarrhea (CDAD), formerly pseudomembranous colitis, has been reported with almost all antibacterial drugs and may range from mild diarrhea to fatal colitis. The most common culprits include clindamycin and lincomycin. Antibacterial therapy alters the normal flora of the colon, leading to overgrowth of C difficile, whose toxins A and B contribute to CDAD development. Morbidity and mortality are increased with hypertoxin-producing strains of C difficile; these infections can be resistant to antimicrobial therapy and may require colectomy. CDAD must be considered in all patients who present with diarrhea after antibacterial use. Since CDAD has been reported to occur more than 2 months after antibacterial use, careful medical history is necessary. Therapy with broad-spectrum antibacterials and other agents with significant antibacterial activity should be administered cautiously in patients with history of gastrointestinal disease, particularly colitis; pseudomembranous colitis (generally characterized by severe, persistent diarrhea and severe abdominal cramps, and sometimes associated with the passage of blood and mucus), if it occurs, may be more severe in these patients and may be associated with flares in underlying disease activity. Antibacterial drugs not directed against C difficile may need to be stopped if CDAD is suspected or confirmed. Appropriate fluid and electrolyte management, protein supplementation, antibacterial treatment of C difficile, and surgical evaluation should be started as clinically indicated.

Organ Transplant

Major:

Cipro XR

The ciprofloxacin in Cipro XR has a major potential interaction with Organ Transplant.

Tendonitis and ruptures of the shoulder, hand, and Achilles tendons have been reported in patients receiving quinolones, both during and after treatment. Avoid the use of these agents in patients who have a history of tendon disorders or have experienced tendinitis or tendon rupture. Therapy with quinolones should be administered cautiously in patients with patients with kidney, heart, and lung transplant, since it may delay the recognition or confound the diagnosis of a quinolone-induced musculoskeletal effect. Factors that may independently increase the risk of tendon rupture include strenuous physical activity, renal failure, and previous tendon disorders such as rheumatoid arthritis. It is recommended to discontinue these agents if, at any time during therapy, pain, inflammation or rupture of a tendon develops and institute appropriate treatment.

Peripheral Neuropathy

Major:

Cipro XR

The ciprofloxacin in Cipro XR has a major potential interaction with Peripheral Neuropathy.

The use of quinolones has been associated with an increased risk of peripheral neuropathy. Monitor closely and discontinue their use in patients experiencing symptoms of peripheral neuropathy. It is recommended to avoid these agents in patients who have previously experienced peripheral neuropathy.

Renal Dysfunction

Major:
