Study Notes

Aminoglycosides

Aminoglycosides are a class of antibiotics commonly used to treat serious infections, such as pneumonia, urinary tract infections, and bloodstream infections.
Aminoglycosides can be given intravenously or intramuscularly.
The most common adverse effects of aminoglycosides include nephrotoxicity and ototoxicity.
Nephrotoxicity may be monitored by checking BUN, creatinine, frequency of urination, and thirst.
Ototoxicity may result in symptoms such as tinnitus, hearing loss, and dizziness.
Avoid aminoglycosides if the patient has sulfite sensitivity, kidney disease, hearing loss, Parkinson's disease, or neuromuscular disorders.
Patients on aminoglycosides should report hearing loss, dizziness, or tingling sensations.

Quinolones

Quinolones are a broad-spectrum antimicrobial class used to treat a variety of infections, including bronchitis, pneumonia, prostatitis, urinary tract infections, and sinusitis.
Common quinolones include Ciprofloxacin, Levofloxacin, and Moxifloxacin.
Serious adverse reactions include anaphylaxis, hypersensitivity reactions, phototoxicity, superinfection, increased intracranial pressure, seizures, and tendon weakness or rupture.
Quinolones should be used with caution in patients with renal or liver failure, geriatric patients, and those with seizure disorders.
Avoid administering quinolones with antacids, iron supplements, or multivitamins, and encourage patients to drink plenty of fluids to minimize crystalluria.
Quinolones should not be used in children, and avoid combining them with medications for heart rhythm disturbances.
Avoid prolonged sun exposure while taking quinolones.

Antituberculars

Antitubercular drugs are used to treat tuberculosis (TB) and prevent Mycobacterium avium complex infections in patients with HIV.
Isoniazid (INH) and Rifampin are commonly used.
Long-term treatment (6 months to 2 years) is often required for TB.
Common adverse reactions include peripheral neuropathy, nausea, vomiting, and elevated liver enzymes.
Antitubercular drugs should be used with caution in patients with renal or liver impairment, or active gastric ulcers.
Rifampin can cause urine, saliva, sweat, tears, and contact lenses to turn a harmless red-orange color.
Patients should report fever, chills, muscle pain, eye pain, fatigue, sore throat, bruising, or yellow skin or eyes.
An overdose may result in nausea, vomiting, tiredness, abdominal pain, yellow skin or eyes, and unconsciousness.
Antitubercular medications may decrease the effectiveness of oral contraceptives.

Antiviral Agents

Antiviral medications are used to treat infections caused by viruses, including cytomegalovirus (CMV), HIV, hepatitis B, herpes simplex virus, and the SARS-CoV-2 virus.
Common antiviral medications include Ganciclovir, Foscarnet, Valganciclovir, Cidofovir, Zidovudine, Lamivudine, Interferon alfa 2b, Famciclovir, Acyclovir, Valacyclovir, and Remdesivir.
Potential adverse effects include thrombocytopenia, neutropenia, pancytopenia, sepsis, and nephrotoxicity.
Lactic acidosis and severe liver problems have been reported with antiviral use.
Antiviral medications may interact with many drugs, including over-the-counter and herbal medications.
Report nausea, vomiting, shortness of breath, weakness, jaundice, or abdominal pain to the physician.

General Information

Culture & sensitivity tests are vital before administering the first dose of antibiotics.
Verify allergy status, especially for penicillin, the most common drug allergy.
Administer IM or IV injections/infusions slowly to minimize local irritation and phlebitis.
Dehydration can lead to decreased drug excretion and potentially raise drug levels to toxic levels.
Assess therapeutic response by observing factors like decreased fever, increased appetite, improved well-being, reduced WBC count, and wound healing.
Monitor for superinfections, especially fungal (Candida being most prevalent), characterized by oral thrush, nausea/diarrhea, abdominal cramps, white vaginal discharge, severe perineal itching, stomatitis, and glossitis.
Counsel patients to complete the entire prescribed course of antibiotics, even if they feel better, to prevent relapse and drug resistance.
Common antibiotics at Henry Ford Health include Piperacillin/tazobactam, ciprofloxacin, levofloxacin, cefazolin, vancomycin, cefepime, gentamicin, tobramycin, ceftriaxone, clindamycin, and azithromycin.

A. Penicillins

Used to treat various infections like tonsillitis, pneumonia, ear infections, bronchitis, urinary tract infections, gonorrhea, and skin infections.
Serious adverse reactions include anaphylaxis, neutropenia, leukopenia, thrombocytopenia, and hepatotoxicity.

Avoid acidic fruit juices as they decompose the medication.
Educate patients to seek emergency medical attention for allergic reaction signs like shortness of breath, hives, facial swelling, rash, or fainting.
Instruct patients to contact their physician if they experience severe or bloody diarrhea and abdominal cramping while on penicillin.
Advise patients that penicillin can decrease the effectiveness of birth control pills, requiring a second method of contraception during treatment.

B. Tetracycline

Monitor patients for signs and symptoms of pancreatitis and bone marrow suppression.

J. Antifungal Agents

Anti-fungal medications are used to treat fungal infections in the mouth, throat, esophagus, vagina, urinary tract, blood, and lungs.
They also prevent fungal infections in immunocompromised individuals like chemotherapy and transplant patients.
Nystatin is used for treating Candida albicans infections and is available in various forms like creams, ointments, powders, vaginal tablets, and oral tablets.
Immunosuppressed patients may need to suck on oral Nystatin tablets for prolonged contact with the oral mucosa.
Amphotericin B is indicated for progressive fungal infections resistant to conventional treatment.
Monitor kidney function for toxicity in patients on Amphotericin B.
Avoid heparin or saline when flushing lines for Amphotericin B; use D5W instead.
Fluconazole can cause hepatotoxicity, Stevens-Johnson syndrome, angioedema, seizures, and leukopenia.
Encourage increased fluid intake with sulfonamides unless contraindicated, to help flush out medication and prevent crystalluria.
Monitor for signs of overdose such as nausea, vomiting, decreased appetite, diarrhea, headache, dizziness, abdominal discomfort, drowsiness, fever, and unconsciousness.
Monitor for QT interval prolongation on cardiac monitors if patients are on sulfonamides.
Educate patients on the potential for sulfamethoxazole and trimethoprim to harm a developing fetus and nursing infants.
Advocate for avoiding prolonged sun exposure while on sulfamethoxazole and trimethoprim due to increased skin sensitivity to sunlight.
Counsel patients on the potential for sulfamethoxazole and trimethoprim to decrease the effectiveness oral contraceptives.
Educate patients to seek immediate medical attention for severe side effects like allergic reactions, unusual bleeding, or yellow skin or eyes.

H. Antituberculars

Rifampin and INH prevent bacterial multiplication and treat/prevent tuberculosis. Rifabutin prevents mycobacterium avium complex in HIV patients.
INH can cause peripheral neuropathy, nausea, vomiting, and elevated AST/ALT levels.
Rifampin can cause headache, fatigue, heartburn, and elevated liver enzymes.
Rifabutin can cause anorexia, nausea, thrombocytopenia, and transient leukopenia.
These drugs are used with caution in patients with renal or liver impairment or gastric ulcers.
Inform patients taking rifampin that it may impart a harmless red-orange color to body secretions.
Administer on an empty stomach, one hour before and two hours after meals.
Monitor patients for fever, chills, muscle/bone pain, blurred vision, eye pain/redness, excessive tiredness, sore throat, unusual bleeding/bruising, or yellow skin/eyes.
Educate patients on overdose symptoms such as nausea, vomiting, tiredness, abdominal pain, yellow skin/eyes, and unconsciousness.
Advise patients not to wear contact lenses while taking Rifabutin or Rifampin as it can permanently turn lenses red-orange.
Inform patients that medication may decrease the effectiveness of oral contraceptives requiring alternative birth control methods.
Treatment is long-term, ranging from six months to two years.
