Adverse drug reactions may lead to which of the following?

Adverse drug reactions (ADRs) are unintended, harmful effects that occur in response to medications. These reactions can exacerbate existing health conditions, leading to worsening health issues for the patient. This can manifest in various ways, such as increased symptoms of the condition being treated or the emergence of new health problems as a result of the medication.

For instance, if a patient is taking medication for hypertension and experiences an adverse reaction like dizziness or increased heart rate, their overall health can be negatively impacted, leading to a decline in their condition. Understanding the implications of ADRs is crucial in medication management, as they can significantly affect both physical wellbeing and the patient's ability to adhere to treatment protocols.

The other options do not accurately reflect the impact of adverse drug reactions. Increased medication effectiveness does not typically result from adverse reactions; rather, these reactions highlight a lack of efficacy. Improvement in patient cooperation is unlikely since adverse reactions may cause frustration or distrust in treatment plans. Lastly, decreased hospital readmission rates contradict the reality that ADRs often result in complications that may require further medical attention, ultimately increasing the likelihood of readmissions.
