Question | Answer |
---|---|
Penicillins Education | DO NOT mix with ahminoglycosides IM into large muscle (warm compress after) Monitor 30 minutes after IV for allergies PO: 1 hours before or 2 hours after meals Probenecid increases effectiveness |
Penicillins ADR | Hyperkalemia Hypernatremia Impaired renal function Parental site irritation Cephalosporin sensitivity |
Tetracycline Education | Poor absorption w/ dairy, iron, laxatives, antacids Increases risk of digoxin toxicity Contraindications (Pregnant/nursing, children younger than 8) Decreases oral contraceptive effectiveness |
Tetracycline ADR | Esophageal ulceration Tooth discoloration Tooth enamel hypoplasia Hepatotoxicity N/V/D Superinfection (C. Diff, yeast infections) |
Vancomycin Education | 1st choice for MRSA PO for antibiotic induced C. Diff and Enterocolitis IV for bone, joint and systemic infections Monitor: I&Os, BUN/creatinine |
Vancomycin ADR | Nephrotoxicity Ototoxicity Thrombophlebitis "Red man syndrome" (flushing, rash, itchin, tachycardia, hypotension) |
Sulfonamides education | NOT SAFE for pregnancy NOT SAFE for impaired kidney function NOT SAFE for over 65 w/ACE or ARBs Beware sun Milk lowers GI upset Drink water Increases warfarin, phenytoin, sulfonylureas, oral hypoglycemic effects |
Sulfonamides ADR | Hyperkalemia Crystalluria Hypersensitivity (sulfonylureas, thiazide, loop diuretics) Blood dyscrasia (anemia etc.) |
Sulfonamides hypersensitivity reactions | Anaphylaxis Photosensitivity Phytotoxicity SJS TENs |
Cefoxitin education | Cephalosporin Ceftriazone IV and calcium = fatal Disulfiram reaction w/ alcohol, cefotetan, cefazolin Probenecid increases effectiveness Similar to penicillins |
Cefoxitin ADRs | Penicillin sensitivity Impaired renal function C. Diff Bleeding (w/cefotetan and ceftriaxone) IV site phlebitis Rash, allergy, anaphylaxis |
Erythromycin education | Macrolide Used if allergic to penicillin/cephalosporin Give on empty stomach w/water NO grapefruit juice Makes antihistamines, theophylline, carbamazepine, warfarin and digoxin TOXIC If taken with Antifungals = tachydysrhythmias and cardiac arrest |
Erythromycin ADRs | Prolonged QT Sudden Cardiac death Ototoxicity Hepatotoxicity C. Diff Epigastric pain N/V/D |
Gentamicin education | Not for long term Hydrate! Narrow therapeutic index (Ototoxicity, Nephrotoxicity) IV |
Gentamicin ADRs | Ototoxicity Nephrotoxicity Streptomycin = neuro disorders (parenthesis) |
Ciprofloxacin education | Not for under 18! Rupture Hydrate! Increased risk of C. Diff Not for myasthenia gravis Theophylline and warfarin may increase plasma levels Decreased absorption w/ aluminum, magnesium, calcium, sucralfate (avoid 6 hours before and 2 hours after) I |
Ciprofloxacin ADRs | N/V/D Achilles tendon rupture Photosensitivity (bad) QT prolongation Superinfection (thrush, vaginal yeast) CNS (dizziness, headache, restlessness, confusion) |
