Adverse Effects

Endocrinologic Adverse Effects

Drug-Induced Hyporeninemic Hypoaldosteronism (see Hypoaldosteronism, [[Hypoaldosteronism]])

  • Physiology
    • Class effect, common to all NSAID’s
    • Dose-dependent COX-inhibition -> decreased renal prostaglandin synthesis -> results in drug-induced hyporeninemic hypoaldosteronism
  • Clinical

Gastrointestinal Adverse Effects

Peptic Ulcer Disease (PUD) (see Peptic Ulcer Disease, [[Peptic Ulcer Disease]])

  • Physiology: class effect, common to all NSAID’s

Pulmonary Adverse Effects

Aspirin-Intolerant Asthma (see Asthma, [[Asthma]])

  • Physiology: class effect, common to multiple NSAID’s

Drug-Induced Pulmonary Eosinophilia (see Drug-Induced Pulmonary Eosinophilia, [[Drug-Induced Pulmonary Eosinophilia]])

  • Associated Agents
    • Acetylsalicylic Acid (Aspirin) (see Acetylsalicylic Acid, [[Acetylsalicylic Acid]])
    • Diclofenac (Aclonac, Cataflam, Voltaren) (see Diclofenac, [[Diclofenac]])
    • Diflunisal (Dolobid)
    • Fenbufen
    • Fenoprofen (see Fenoprofen, [[Fenoprofen]]): case reports
    • Ibuprofen (Advil, Brufen, Motrin, Nurofen) (see Ibuprofen, [[Ibuprofen]]): case reports
    • Indomethacin (Indocin) (see Indomethacin, [[Indomethacin]])
    • Loxoprofen
    • Meloxicam (see Meloxicam, [[Meloxicam]])
    • Naproxen (Naprosyn, Aleve) (see Naproxen, [[Naproxen]]): appears to be more frequent with naproxen than other NSAID’s

    • Phenylbutazone
    • Piroxicam (Feldene) (see Piroxicam, [[Piroxicam]])
    • Pranoprofen

  • Clinical
    • Cough
    • Dyspnea
    • Fever

Renal Adverse Effects

Acute Kidney Injury (see Acute Kidney Injury, [[Acute Kidney Injury]])

  • xxx

Acute Interstitial Nephritis (see Acute Interstitial Nephritis, [[Acute Interstitial Nephritis]])

  • Physiology: class effect, common to all NSAID’s

Hyperkalemia (see Hyperkalemia, [[Hyperkalemia]])

  • Mechanism: due to drug-induced hyporeninemic hypoaldosteronism

Increased Renal Sodium Reabsorption with Peripheral Edema

  • Risk Factors
  • Physiology: decreased PGE2 -> increased renal sodium reabsorption
    • Class Effect: common to all NSAID’s
    • Dose-Dependent Effect
  • Clinical: typically occurs during the first week of therapy

Type 4 Renal Tubular Acidosis (RTA) (see Type 4 Renal Tubular Acidosis, [[Type 4 Renal Tubular Acidosis]])
