Drug therapy plan for patient HL
Three current medications and possible hepatitis C are the case. The diagnosis has to account for the drugs the patient is already on, not just the symptoms they arrived with.

Three drugs, one history, and a diagnosis to justify
The medication list is not background information to be skimmed on the way to the symptoms — it is most of the case, and the diagnosis depends on reading it that way. HL presents with nausea, vomiting and diarrhoea, and the assignment asks for a diagnosis with your rationale, which means working out whether the symptoms are caused by an illness, by the drugs, or by an interaction between them. Each of the three named medications is relevant. Levothyroxine has a narrow therapeutic index and its absorption is affected by gastrointestinal transit, so diarrhoea can shift a stable patient. Prednisone carries gastrointestinal effects of its own and cannot be stopped abruptly after sustained use. Nifedipine is hepatically metabolised, which matters given the possible hepatitis C, and so is prednisone's conversion to its active form. Reading the list this way turns three lines of background into the substance of the differential.
The history of drug abuse and possible hepatitis C is doing two kinds of work and both belong in the answer. Clinically, impaired hepatic function alters the metabolism of drugs cleared by the liver, so doses that were appropriate may no longer be, and confirming hepatitis C status becomes part of the plan rather than a footnote. Diagnostically, it widens the differential to include withdrawal, hepatitis itself, and effects of substances not on the prescription list. Say what you would establish before prescribing anything — hepatitis C testing, liver function, thyroid function, a full medication and substance history including over-the-counter products. Then justify the plan with the specificity the brief asks for: which drug you would adjust, in which direction, monitored by which parameter, and why that ordering rather than another. Vague plans lose marks here precisely because the brief asks for examples, which is an instruction to be concrete.
Likely learning objectives
Inferred from the brief — check these against your own rubric.
- 01Evaluate whether presenting symptoms arise from illness, medication or interaction.
- 02Adjust drug therapy for suspected hepatic impairment.
- 03Sequence assessment before prescribing when key information is missing.

Course-wide instructions that accompany this question
You must proofread your paper. But do not strictly rely on your computer’s spell-checker and grammar-checker; failure to do so indicates a lack of effort on your part and you can expect your grade to suffer accordingly. Papers with numerous misspelled words and grammatical mistakes will be penalized. Read over your paper – in silence and then aloud – before handing it in and make corrections as necessary. Often it is advantageous to have a friend proofread your paper for obvious errors. Handwritten corrections are preferable to uncorrected mistakes. Use a standard 10 to 12 point (10 to 12 characters per inch) typeface. Smaller or compressed type and papers with small margins or single-spacing are hard to read. It is better to let your essay run over the recommended number of pages than to try to compress it into fewer pages. Likewise, large type, large margins, large indentations, triple-spacing, increased leading (space between lines), increased kerning (space between letters), and any other such attempts at “padding” to increase the length of a paper are unacceptable, wasteful of trees, and will not fool your professor. The paper must be neatly formatted, double-spaced with a one-inch margin on the top, bottom, and sides of each page. When submitting hard copy, be sure to use white paper and print out using dark ink. If it is hard to read your essay, it will also be hard to follow your argument
Turn the brief into deliverables
- 01A two-page paper with a stated diagnosis and rationale.
- 02A drug therapy plan addressing each current medication.
- 03A justification with specific examples, as the brief requires.
- 04APA citations to pharmacology or guideline sources.
Diagnosis, then plan, then why this plan
Read the medication list as evidence
Assess how levothyroxine, nifedipine and prednisone each relate to the presentation.
State the diagnosis and rationale
Commit to a leading explanation and say what supports it over the alternatives.
Establish what is missing
Name the tests and history required before any prescribing decision.
The therapy plan
Address each medication — adjust, hold, continue — with monitoring parameters.
Justify with examples
Explain why this plan and this ordering, using the case's specifics.
Interaction checking and hepatic dosing
Recommended databases
- Lexicomp or your programme's drug reference
- AASLD hepatitis C guidance
- PubMed
- FDA prescribing information
- Your pharmacology textbook
Search sequence
- 1.Check each drug's hepatic metabolism and dose adjustment guidance in a primary drug reference.
- 2.Run a formal interaction check on the three-drug combination rather than relying on recall.
- 3.Read current hepatitis C testing guidance so the assessment step is specific.
- 4.Look up corticosteroid tapering rules before writing anything about stopping prednisone.

Review before submission
Common mistakes
- Diagnosing from the symptoms alone and ignoring the three current medications.
- Recommending abrupt discontinuation of prednisone.
- Overlooking that hepatic impairment changes clearance of the drugs already prescribed.
- Justifying the plan in general terms when the brief asks for specific examples.
Submission checklist
- Does your rationale account for all three current medications?
- Have you addressed the implications of possible hepatitis C for metabolism?
- Is there an assessment step before any prescribing decision?
- Is each recommendation justified with a specific example?
