Discussing side effects honestly is one of the highest-leverage moves in prescribing. The patient who is warned and prepared tolerates side effects better, recognizes them earlier, and engages with you when they emerge. The patient who is surprised by side effects often discontinues medication without telling you and returns weeks later with the original symptoms unchanged.
Honest without overwhelming. Listing every possible side effect from the package insert produces information overload. Focus on the common ones the patient will likely encounter, the serious ones they need to recognize, and the ones likely to limit adherence specifically. Calibrate to the patient — the anxious patient who Googles everything needs different framing than the patient who wants minimal detail.
Common AEs: what to expect, when, how long it typically lasts, what to do if it bothers them. "GI symptoms in the first 1-2 weeks are common; usually resolve by week 3. Take with food. Let me know if it's severe enough that you want to stop." Setting expectations prevents the first-week discontinuation that loses half of adherence cases.
Serious AEs: rare but important to recognize. "If you develop a rash, stop the medication and call me immediately." "If you experience confusion or muscle stiffness with fever, this is a medical emergency — go to the ED." Name specifically what would prompt urgent contact; the patient who knows what to watch for catches problems earlier.
Ask the patient's specific concerns. "What worries you most about side effects?" Often the patient's specific concern is different from what you'd anticipate. The young man worried about sexual dysfunction. The patient with prior weight issues worried about weight gain. The patient with a parent who had bad medication reactions worried about idiosyncratic responses. Address the specific concern.
Sexual side effects deserve specific discussion. SSRIs cause sexual dysfunction in 30-70 percent of patients; many won't volunteer the topic. Raise it: "These medications commonly cause sexual side effects — delayed orgasm, lower libido, sometimes erectile difficulty. I bring it up because it's common and because there are options if it happens." Normalize and pre-empt; otherwise patients silently discontinue.
Surprise side effects damage trust. The patient who experiences something you didn't warn them about wonders what else you haven't told them. Honest, calibrated discussion at prescription builds the trust that makes adherence possible.
