A patient has started taking clopidogrel (Plavix) after experiencing a transient ischemic attack. What adverse effects are associated with this drug? (Select all that apply)

A. Hypothermia: Clopidogrel is not typically associated with temperature regulation and wouldn't cause hypothermia.

B. Hypotension: While some medications can cause low blood pressure (hypotension), clopidogrel is not a common culprit.

C. Black stools: This can be a sign of upper gastrointestinal bleeding, which is a potential side effect of clopidogrel. Clopidogrel inhibits platelet aggregation, which can increase bleeding risk.

D. Constipation: Constipation is not a common side effect of clopidogrel.

A. Constipation: Constipation is not a commonly reported adverse effect of clopidogrel (Plavix). Clopidogrel is an antiplatelet medication that works by inhibiting platelet aggregation, and gastrointestinal effects such as constipation are not typically associated with its use.

B. Bruising: This is a correct answer. Bruising is a known adverse effect of clopidogrel. As an antiplatelet medication, clopidogrel inhibits platelet aggregation, which can increase the risk of bleeding and bruising.

C. Rash: Rash is a potential adverse effect of clopidogrel, although it is not as common as other side effects such as bruising or gastrointestinal symptoms. Patients taking clopidogrel should be monitored for signs of allergic reactions, including rash, which may indicate the need for further evaluation or discontinuation of the medication.

D. Headache: Headache is not a commonly reported adverse effect of clopidogrel. While some patients may experience headache while taking clopidogrel, it is not considered a frequent or significant side effect of the medication.

E. Diarrhea: Diarrhea is not a commonly reported adverse effect of clopidogrel. Gastrointestinal symptoms such as diarrhea are not typically associated with clopidogrel use, although some patients may experience gastrointestinal upset as a side effect of antiplatelet therapy.
