Final answer:
Clients allergic to aspirin should avoid other NSAIDs and medications containing aspirin or aspirin-like compounds, due to the risk of allergic reactions and other side effects.
Step-by-step explanation:
Clients who are allergic to aspirin should avoid other non-steroidal anti-inflammatory drugs (NSAIDs), which can cause similar allergic reactions. NSAIDs include drugs like ibuprofen and naproxen. Additionally, it's important to be cautious with medications containing aspirin or aspirin-like compounds, such as some combination pain relievers. Medications to avoid would also include aspirin-containing anticoagulants, as aspirin plays a role in inhibiting blood clot formation. Consulting a physician before beginning or changing any medication regimen is strongly recommended due to potential side effects, including gastrointestinal issues.
