Study Notes
Antibiotic Treatment
- Broad-spectrum antibiotics are used initially, then narrowed down to specific antibiotics when the infection is identified.
- Prodromal stage of infection is when symptoms begin to show.
- Infections can be transmitted during the incubation period before symptoms appear.
- Convalescent period patients may still be able to transmit the infection even though they are recovering. This is crucial for infections like Hepatitis A and Coxsackievirus.
- Penicillin is effective against Gram-positive bacteria by targeting the bacterial wall. If a patient has a penicillin allergy, cephalosporins should not be administered due to similarities.
- Tetracyclines are broad-spectrum antibiotics and can cause liver damage, increase the risk of sunburn, and may induce bone deformities in pregnant women.
- Erythromycin should be taken on an empty stomach with a full glass of water.
- Gentamicin can cause ototoxicity (hearing damage) and nephrotoxicity (kidney damage).
- Ciprofloxacin can cause tendon rupture, especially the Achilles tendon. It is also associated with hepatotoxicity and patients should report leg pain or swelling immediately.
- Trimethoprim-sulfamethoxazole (Bactrim) can cause sulfa allergies. High hydration is crucial to prevent crystal formation in the bladder and blood. It can also reduce platelet production.
- Vancomycin is commonly used to treat MRSA and can cause nephrotoxicity and ototoxicity. Administering vancomycin too quickly can lead to “Red Man Syndrome.
Antifungal Treatment
- Amphotericin B is a powerful antifungal, but can damage the kidneys. It targets ergosterol in fungal cell membranes leading to elevated BUN and Creatinine levels.
- Fluconazole is effective against yeasts and fungal infections.
- Chloroquine can cause retinopathy (eye damage) and blindness.
Antiviral Treatment
- Acyclovir is a broad-spectrum antiviral medication used to treat various viral infections.
- HIV progresses to AIDS when CD4 count drops below 200.
Mental Health Medications
- Flumazenil is the antidote for benzodiazepine overdose.
- Buspirone interacts adversely with grapefruit.
- St. John’s Wort should be avoided when taking mental health medication.
- Zolpidem is indicated for short-term insomnia (7-10 days).
- Sertraline (an SSRI) is effective in improving mood.
- Fluoxetine (an SSRI) should be taken in the morning and tapered slowly to avoid withdrawal symptoms.
- Duloxetine (an SNRI) can cause weight gain and has an increased risk of suicidal ideation in teenagers and children.
- Bupropion is used for smoking cessation.
- Lithium therapeutic levels range from 0.6 to 1.2mmol/L.
- Methylphenidate is used to treat attention-deficit/ hyperactivity disorder (ADHD).
- Neuroleptic Malignant Syndrome (NMS) is a potentially fatal complication of antipsychotic medication, characterized by rigidity, hyperthermia, altered mental status, and autonomic dysfunction. Haloperidol is one medication that can potentially cause NMS.
Addiction Treatment
- Buprenorphine, methadone substitution, and clonidine are used for opioid withdrawal management.
- Varenicline is used for nicotine cessation.
Important Considerations
- Patient education: Emphasize the importance of completing the full course of antibiotics to prevent antibiotic resistance.
- Monitoring: Monitor patients closely for side effects and adverse reactions, especially when using potent or potentially toxic medications.
- Allergy Assessment: Thoroughly assess patients for allergies, particularly for penicillin and sulfa drugs.
- Hydration: Encourage adequate hydration to prevent complications, especially with medications like trimethoprim-sulfamethoxazole.
- Liver, Kidney, and Eye Function: Monitor patients for liver, kidney, and eye problems, as some medication can cause damage to these organs.
Broad Spectrum Antibiotics
- Broad spectrum antibiotics target a wide range of bacteria, commonly used initially for infections.
- Narrow spectrum antibiotics target specific bacteria, used when the specific bacteria causing infection is identified.
Infection Stages
- Incubation period: The time between exposure to a pathogen and the onset of symptoms, during which the pathogen multiplies and can be transmitted.
- Prodromal stage: The period when the first mild symptoms begin to appear.
- Acute stage: The peak of the illness, characterized by the most severe symptoms.
- Convalescent stage: The recovery period when the symptoms gradually subside, but some infections can still be transmitted (hepatitis A, Coxsackie virus).
Antibiotic Resistance
- Acquired resistance: Bacteria can develop resistance to antibiotics, making treatment less effective.
- Treatment adherence: Following the entire prescribed antibiotic course is crucial to prevent antibiotic resistance.
Penicillin
- Gram-positive bacteria: Penicillin is effective against gram-positive bacteria by interfering with their cell wall synthesis.
- Birth control: Penicillin can interfere with oral contraceptives.
- Anaphylaxis: Ask patients about any history of penicillin allergy before administering the medication.
Cephalosporins
- Similar to penicillin: Cephalosporins share similarities with penicillin (e.g., cefazolin) and may trigger allergic reactions in patients with penicillin allergies.
- Cell wall inhibition: They inhibit bacterial cell wall synthesis.
Tetracyclines
- Take with food: To minimize gastrointestinal upset, tetracyclines (e.g., doxycycline) should be taken with food.
- Birth control: Tetracyclines can interfere with oral contraceptives.
- Liver toxicity: Can cause liver function abnormalities.
- Photosensitivity: Increase the risk of sunburn.
- Milk interaction: Avoid taking tetracycline with milk.
- Kidney function: Monitor kidney function tests before and during treatment.
- Pregnancy: Can cause bone malformations in the fetus if taken during pregnancy.
Erythromycin
- Broad spectrum: Effective against a variety of bacteria.
- Empty stomach: Administer on an empty stomach with a full glass of water.
Gentamicin
- Ototoxicity: Can damage the ears.
- Nephrotoxicity: Can damage the kidneys.
Ciprofloxacin
- Gram-negative bacteria: Effective against gram-negative bacteria.
- Achilles tendon rupture: Can cause achilles tendon rupture, so monitor for leg pain or swelling.
- Hepatotoxicity: Can cause liver damage.
Trimethoprim-sulfamethoxazole (TMP-SMX)
- Sulfa allergy: Avoid in patients with sulfa allergies.
- Bactrim: Also known as Bactrim, it can negatively affect the bladder and blood.
- Hydration: Encourage increased hydration to prevent crystal formation.
- Platelet production: Can reduce platelet production, monitoring is crucial.
Vancomycin
- Nephrotoxicity: Can damage the kidneys.
- Ototoxicity: Can damage the ears.
- Red Man’s Syndrome: Rapid intravenous administration can cause a flushing reaction.
- Intravenous administration: Administered intravenously, not orally.
- MRSA treatment: Commonly used to treat methicillin-resistant Staphylococcus aureus (MRSA).
Isoniazid
- Hepatotoxicity: Can cause liver damage.
- Nerve damage: Can damage nerves, causing hand/feet tingling or spasms.
- Vitamin B6: Supplementation with vitamin B6 is required to prevent nerve damage.
Amphotericin B
- Fungal infection: A potent antifungal that is used for severe fungal infections.
- Ergosterol inhibition: Targets ergosterol, a component of fungal cell membranes.
- Kidney damage: Can cause kidney damage, monitor BUN, creatinine, and potassium levels.

Chloroquine
- Antimalarial: Used to treat malaria.
- Retinopathy: Can cause visual impairment.
Metronidazole
