Anabolic–androgenic steroids (AAS) are synthetic derivatives of testosterone designed to promote muscle growth, enhance athletic performance, and improve physical appearance. While they can be prescribed for certain medical conditions—such as delayed puberty, some forms of anemia, or hormone replacement therapy—they are often misused outside the clinic, which carries significant health and legal risks.
Key points to consider
Aspect Typical medical use Common non‑medical misuse Main concerns
Hormonal effect Replacement of deficient testosterone Boosting muscle mass, strength, or endurance Hormone imbalance → gynecomastia, acne, mood swings
- Follow‑up schedule: 3–6 months post-initiation, then annually.
Have a contingency plan
- If adverse effects arise (e.g., elevated lipids), have strategies ready: dose adjustment, switch to a different medication class, lifestyle interventions.
By systematically evaluating each risk factor and planning for mitigation, the prescriber can reduce the likelihood of serious side effects while still providing therapeutic benefit.

3. Practical Decision‑Making Framework
Below is an outline (flow‑chart style) that can be applied in practice:
Step Action Key Questions
1 Identify all patient‑specific risk factors (age, comorbidities, medications, lab values). What are the patient’s age, renal/hepatic function, and comorbid conditions?
2 Quantify absolute risk for each adverse outcome. What is the baseline incidence of this side effect in similar patients?
3 Estimate incremental risk added by the drug (difference between exposed and unexposed groups). How much does the drug increase the risk relative to placebo?
4 Calculate NNT/NNH for each outcome. How many patients need treatment for one benefit or harm?
5 Balance benefits vs harms using a decision‑analytic framework (e.g., cost‑utility, QALY). Does the drug’s benefit outweigh its risk when expressed in terms of life‑years gained versus lost?
6 Consider patient preferences and values. Will patients accept a higher risk for potential gain?
4.3 Example: Cardiovascular Drug with Mild Benefit
Major cardiovascular event reduction 0.5% 200 Need to treat 200 patients for one event prevented
Myocardial infarction increase 0.1% 1000 One additional MI per 1000 treated
Key Takeaway: Even a modest benefit may outweigh a small risk if the absolute numbers favor prevention of serious outcomes, especially in high‑risk populations.

4. Practical Decision‑Making Framework
Below is a step‑by‑step guide that clinicians can use to decide whether to prescribe a medication and at what dose.
What is the primary objective? (e.g., control hypertension, reduce infection risk).
Are there multiple competing goals? Prioritize.
Step 3: Gather Evidence
Look up recent systematic reviews or guidelines for this drug class.
Note the range of effective doses and associated adverse events.
Step 4: Calculate Benefit vs. Risk at Various Doses
Dose Expected Benefit (e.g., BP reduction) Probability/Severity of Adverse Event
Low Modest Minimal
Medium Adequate Moderate
High Maximal Significant
Use clinical decision support tools if available.
Step 5: Select Dose
Choose the lowest dose that achieves clinically meaningful benefit while keeping adverse event risk acceptable. If patient-specific factors (e.g., frailty, comorbidities) increase risk, opt for a lower dose even if it means less benefit.
