Moderate:

chloramphenicol chlorotrianisene

Applies to: chloramphenicol and chlorotrianisene

Chloramphenicol may increase the blood levels and effects of chlorotrianisene. You may need a dose adjustment or more frequent monitoring by your doctor to safely use both medications. Contact your doctor if your condition changes or you experience increased side effects, such as changes in weight and/or appetite, dizziness, headaches, upset stomach, nausea, vomiting, bloating, and/or bleeding between menstrual cycles. Seek immediate medical care if you experience any of the following, as they could indicate that you are experiencing a serious side effect: dark urine; light-colored stools; yellow skin or eyes; very bad headache or dizziness; passing out; change in eyesight or a change in how contact lenses feel; severe upset stomach; severe vomiting; pain in the upper right belly area, right shoulder area, or between the shoulder blades; chest pain or pressure; coughing up blood; trouble breathing; swelling, warmth, numbness, change of color or pain in a leg or arm; trouble speaking or swallowing; depression or other mood changes; a lump in the breast; breast pain or soreness; nipple discharge; bone pain; and/or muscle cramps or spasms.

On the other hand, antibiotics such as chloramphenicol can also reduce the amount of estrogen available in the body from estrogen containing hormonal medications. If you are using an estrogen containing medication for birth control, you may be at increased risk for pregnancy or breakthrough bleeding. Be sure to alert your doctor if you are having any vomiting and/or diarrhea as this too can impact how well your hormonal birth control works. Talk to your doctor or pharmacist to determine if you should use an alternative or additional form of birth control during or after treatment with chloramphenicol. If you are using an estrogen containing medication for a purpose other than birth control, discuss any questions you may have or any changes you notice regarding how well your medication is working with your doctor. 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

4 potential interactions Applies to: 4 conditions, including Liver Disease, Noninfectious Colitis, Renal Dysfunction, and Bone Marrow Depression/Low Blood Counts.

Bone Marrow Depression/Low Blood Counts

Major:

chloramphenicol

Chloramphenicol has a major potential interaction with Bone Marrow Depression/Low Blood Counts.

Chloramphenicol may cause bone marrow depression and other hematologic toxicities, which can be irreversible or reversible. The former type is independent of dose and results in aplastic anemia with a high rate of mortality, generally from hemorrhage or infection. It has been reported following both systemic and topical administration of chloramphenicol and has an estimated incidence of 1 in 25,000 to 1 in 40,000 courses of therapy. Bone marrow aplasia or hypoplasia may occur after a single dose but more often develops weeks or months after the drug has been discontinued. A reversible myelosuppression occurs much more frequently and is characterized by anemia, vacuolation of red blood cells, decreased reticulocyte count, leukopenia, thrombocytopenia, increased serum iron concentrations, and increased serum iron-binding capacity. It is dose-dependent, occurring regularly at chloramphenicol dosages exceeding 4 g/day (in adults) or at plasma drug concentrations >= 25 mcg/mL, and usually responds to withdrawal of the drug. Therapy with chloramphenicol should be administered cautiously, if at all, in patients with preexisting blood dyscrasias and/or bone marrow depression. Complete blood counts and differential reticulocyte counts should be performed in all patients prior to initiating therapy and approximately every 2 days during therapy. Marked depression of blood counts and/or development of other hematologic abnormalities may be indication for withdrawal of chloramphenicol therapy.

Liver Disease

Major:

chloramphenicol

Chloramphenicol has a major potential interaction with Liver Disease.

Chloramphenicol is primarily inactivated by glucuronyl transferase in the liver and eliminated in the urine as both parent drug and metabolites. In adults with normal renal and hepatic function, only 5% to 15% of a dose of chloramphenicol is excreted unchanged by the kidney, but approximately 30% is excreted when chloramphenicol is administered intravenously as the sodium succinate ester. However, the fraction of drug excreted unchanged may be highly variable, especially in neonates and children. Therapy with chloramphenicol should be administered cautiously in patients with significantly impaired renal and/or hepatic function, since drug accumulation may occur in such patients. The dosage should be reduced based on the degree of impairment as well as plasma drug concentrations.

Noninfectious Colitis

Major:

chloramphenicol

Chloramphenicol 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.

Renal Dysfunction

Major:

chloramphenicol

Chloramphenicol has a major potential interaction with Renal Dysfunction.

Chloramphenicol is primarily inactivated by glucuronyl transferase in the liver and eliminated in the urine as both parent drug and metabolites. In adults with normal renal and hepatic function, only 5% to 15% of a dose of chloramphenicol is excreted unchanged by the kidney, but approximately 30% is excreted when chloramphenicol is administered intravenously as the sodium succinate ester. However, the fraction of drug excreted unchanged may be highly variable, especially in neonates and children. Therapy with chloramphenicol should be administered cautiously in patients with significantly impaired renal and/or hepatic function, since drug accumulation may occur in such patients. The dosage should be reduced based on the degree of impairment as well as plasma drug concentrations.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No interaction information available.
