Common Adverse Effects of Prescribed Medications
Adverse effects from commonly prescribed medications are a significant concern in healthcare, affecting patient quality of life and sometimes leading to hospital admissions or serious complications 348. These effects can impact various body systems, including the oral cavity, central nervous system, gastrointestinal tract, cardiovascular system, and even the eyes 1356+1 MORE.
Oral and Perioral Adverse Effects of Medications
Many medications cause oral side effects such as gingival enlargement, oral hyperpigmentation, hypersensitivity reactions, medication-related osteonecrosis, and xerostomia (dry mouth) 156. Other reported oral manifestations include mucosal ulceration, taste disorders, gingival bleeding, burning sensations, movement disorders like bruxism, and oral pigmentation 15. Psychotropic drugs, especially antidepressants and antipsychotics, frequently cause xerostomia, dysgeusia (altered taste), and movement disorders such as tardive dyskinesia . Recognizing and managing these oral adverse effects is important for maintaining patient adherence and preventing more serious outcomes 156.
Systemic Adverse Drug Reactions: Central Nervous, Gastrointestinal, and Cardiovascular Systems
The most common adverse drug reactions (ADRs) in primary care involve the central nervous system, gastrointestinal system, and cardiovascular system . These reactions can include drowsiness, blurred vision, gastrointestinal upset, and cardiovascular effects such as hypotension 234. Drug allergies are also a frequent cause of ADRs, while unpredictable (idiosyncratic) reactions are less common .
Adverse Effects in Special Populations: The Elderly
Older adults are particularly vulnerable to ADRs due to multiple health conditions and the use of several medications (polypharmacy) 48. In this group, hypotensive drugs, antiparkinsonian drugs, psychotropics, and diuretics are associated with a higher risk of adverse reactions, including falls, delirium, and increased risk of stroke with antipsychotics 48. Many of these reactions are potentially avoidable with careful prescribing and regular medication review .
Adverse Effects of Antidepressants
Antidepressants are widely used and often cause adverse effects such as dry mouth, weight gain, drowsiness, blurred vision, sexual dysfunction, and increased appetite 26. These effects are more common when multiple antidepressants are used together, highlighting the importance of monotherapy when possible .
Adverse Reactions to Antimicrobial Agents
Antimicrobial drugs, while generally safe, can cause mild adverse reactions, most commonly affecting the skin and gastrointestinal tract . Monitoring for these reactions is important to ensure patient safety and effective treatment .
Ocular Adverse Effects
Some systemic medications can cause vision-threatening side effects, though these are less common. Recognizing these potential risks is important for early intervention and prevention of serious ocular complications .
Immune-Related Adverse Events and Common Medications
In patients receiving immune checkpoint inhibitor therapy, commonly prescribed medications such as metformin, loop diuretics, and proton pump inhibitors do not significantly increase the risk of severe immune-related adverse events .
Conclusion
Adverse effects from commonly prescribed medications are diverse and can affect multiple organ systems, with oral, gastrointestinal, central nervous, and cardiovascular effects being most common. Special populations, such as the elderly and those on multiple medications, are at higher risk. Careful prescribing, patient education, and regular monitoring are essential to minimize these risks and improve patient outcomes 1234+4 MORE.
