When you start taking an antidepressant, you’re not just hoping it works-you’re hoping it works without wrecking your life. But too often, people stay on meds that aren’t helping, or quit because the side effects feel worse than the depression. The truth? Monitoring both effectiveness and side effects isn’t just something your doctor should do-it’s something you can and should be part of. And it makes a real difference.
Why Most People Don’t Know If Their Antidepressant Is Working
A 2022 survey by the National Alliance on Mental Illness found that 74% of people on antidepressants experience side effects, but only 39% felt their doctor actually talked about them. Meanwhile, nearly 70% of patients reported their provider never used a standardized scale to measure mood changes. That’s not negligence-it’s systemic. Most doctors are stretched thin. A 15-minute appointment doesn’t leave room for deep dives into sleep patterns, libido changes, or whether you’ve cried three times this week because the meds are dulling your emotions, not lifting your mood. But here’s what works: structured tracking. The PHQ-9 is a simple, nine-question tool that scores depression severity from 0 to 27. A score above 15 means moderate to severe depression. If you start at 20 and after six weeks you’re at 12? That’s progress. If you’re still at 19? That’s a signal to adjust. The Beck Depression Inventory (BDI) and Hamilton Depression Rating Scale (HDRS) are more detailed, but PHQ-9 is the gold standard for patient-led tracking because it’s free, fast, and validated in over 200 studies.Side Effects Are Not Just "Normal"-They’re Measurable
You’ve probably heard, "Everyone gets side effects." But that’s not helpful. Some side effects are mild and fade. Others-like sexual dysfunction, weight gain, brain zaps, or emotional numbness-can make you quit cold turkey. The Antidepressant Side-Effect Checklist (ASEC) lists 15 common ones: dry mouth, tremors, dizziness, nausea, insomnia, fatigue, sweating, and yes, sexual problems. Each is rated 0 to 4: "not at all" to "very severe." A 2022 study in the International Journal of Impotence Research found that 61% of people stopped SSRIs because of sexual side effects-and only 12% of their doctors had ever asked about it. That’s not normal. It’s a failure of care. But if you track it yourself, you can bring concrete data to your appointment: "For the last month, I’ve rated my libido at 4/4 on the ASEC. My partner noticed I’ve withdrawn. I’m not okay with this." That’s a conversation starter. And it works.What Success Looks Like-Beyond Just Feeling "Better"
Remission isn’t just "I don’t cry every day." It’s functional. Can you get out of bed? Do you have energy to shower? Can you hold a conversation without zoning out? The NIH recommends setting 3-5 specific, measurable goals when you start treatment. Examples:- "Work 4 days a week by week 6."
- "Cook dinner for myself 3 times a week."
- "Text my sister once a week without feeling overwhelmed."
Your Personal Monitoring Toolkit (No Doctor Required)
You don’t need a clinic visit to start monitoring. Here’s how to build your own system:- Download a free PHQ-9 app (like Moodfit or Sanvello) or print the form from the PHQ Screeners website. Fill it out every Monday morning.
- Keep a side effect log. Use a notebook or notes app. Rate each symptom from 0 to 4 on the ASEC scale. Note timing: "Nausea started 2 hours after taking pill on Tuesday."
- Track one functional goal weekly. Example: "Did I leave the house today? Yes/No."
- Review your logs every two weeks. Look for patterns: "Mood improved after I stopped caffeine. Side effects got worse after I skipped sleep."
When to Ask for Help-And What to Say
Don’t wait until you’re miserable. Schedule a check-in every 2-4 weeks during the first 3 months. Bring your logs. Say this:- "My PHQ-9 went from 18 to 11 in six weeks, but I still can’t get out of bed on Sundays."
- "I’ve rated my sexual desire at 4/4 for the last 8 weeks. I need to talk about alternatives."
- "I’ve been taking my pill daily, but I feel like a zombie. Could we check my blood levels?"
What Doesn’t Work (And Why)
Digital apps are helpful, but they’re not perfect. A 2021 review in JMIR mHealth found mobile mood trackers had only 0.72 test-retest reliability-lower than paper scales (0.85+). Don’t rely on them alone. Don’t trust vague questions like, "How are you feeling?" That’s not monitoring. That’s guessing. Also, don’t wait for your doctor to bring it up. Most don’t. In a 2022 study in the Annals of Family Medicine, when nurses administered PHQ-9 forms during routine visits, fidelity was 87%. That means you can ask for one. Just say: "Can I fill out the depression scale before I see the doctor? I want to make sure we’re on the same page." And don’t ignore sleep, diet, or movement. A 2023 Nature Mental Health study showed that people who improved their sleep hygiene while on antidepressants were 2.3 times more likely to respond. Medication isn’t the only tool. But it’s the one you can track.What’s Changing in 2025
The FDA cleared the first digital therapeutic, Rejoyn, in January 2024. It requires weekly PHQ-9 completion and cognitive exercises. The American Psychiatric Association updated its guidelines in June 2024 to require systematic monitoring of both efficacy and side effects at every stage of treatment. And companies like Quartet and Lyra Health now build monitoring into every depression care plan. Pharmacogenetic testing-like GeneSight-is also gaining traction. A 2023 JAMA Psychiatry study showed it reduced side effects by 30% and improved response rates by 20% in eight weeks. It’s not cheap, but it’s becoming more accessible. Ask your provider if it’s an option.Final Thought: You’re Not Just a Patient. You’re a Partner.
Antidepressants aren’t magic pills. They’re tools. And tools need feedback. Tracking your mood, side effects, and daily function isn’t extra work-it’s the most powerful thing you can do to take control. You don’t need to be perfect. You don’t need to log every day. But if you track consistently for even four weeks, you’ll see patterns no doctor could guess. The goal isn’t to feel happy all the time. It’s to feel like yourself again. And you can’t get there without knowing what’s working-and what’s not.How often should I track my mood and side effects?
Start by tracking your mood using PHQ-9 every Monday and side effects daily for the first 4-6 weeks. After that, reduce to once a week if things are stable. If you’re adjusting medication or experiencing new side effects, go back to daily logging. Consistency matters more than perfection.
Can I use my phone to track my antidepressant progress?
Yes, apps like Moodfit and Sanvello are helpful for daily logging and reminders. But don’t rely on them alone. They’re less reliable than paper-based scales like PHQ-9 or ASEC. Use them as a supplement, not a replacement. Always bring printed or exported logs to your appointments.
What if my doctor doesn’t believe my side effects are real?
Bring your logs. Numbers don’t lie. Show your ASEC scores, your PHQ-9 trends, and your functional goals. If your doctor dismisses you, ask for a referral to a psychiatrist who specializes in treatment-resistant depression or psychopharmacology. You deserve care that listens.
Is it normal to feel worse before feeling better?
Yes. Many people experience increased anxiety, insomnia, or emotional numbness in the first 1-3 weeks. This is common with SSRIs and SNRIs. But if symptoms get worse after week 4, or you have new thoughts of self-harm, contact your provider immediately. Don’t wait. This isn’t "normal"-it’s a warning sign.
How do I know if my antidepressant is working?
Look for two things: 1) Your PHQ-9 score drops by at least 50% by week 6. 2) You’re doing things you couldn’t do before-like showering regularly, talking to friends, or going to work. If your mood score improves but your life doesn’t, the treatment isn’t fully working. Talk to your doctor about adjusting dose, timing, or switching meds.
Should I ask for a blood test to check my antidepressant levels?
Yes-if you’re not responding after 6-8 weeks, or if side effects are severe despite low doses. Therapeutic Drug Monitoring (TDM) can show if you’re underdosed, overdosed, or metabolizing the drug too fast or slow. It’s not routine, but it’s evidence-based. Ask your doctor for a referral to a lab that does LC-MS/MS testing.
What if I want to stop my antidepressant?
Never stop abruptly. Tapering under medical supervision reduces withdrawal symptoms like brain zaps, dizziness, and nausea. Use your tracking logs to show your provider your progress and reasons for wanting to stop. Together, you can plan a safe exit-or switch to a different medication with fewer side effects.

So you’re telling me I’m supposed to become a full-time data entry clerk just to keep my brain from turning into mush? Cool. I’ll just add PHQ-9 logging to my list of things I do instead of sleeping. At least the side effects are predictable-like how my libido vanished faster than my will to live after week two. Thanks for the checklist, I guess. Now if only my doctor hadn’t rolled their eyes when I showed them my ASEC scores…
i’ve been using moodfit and it helps… but sometimes i forget to log. then i feel guilty. then i feel worse. it’s a loop. but yeah, writing down when i cry or can’t get up matters. my dr actually noticed the pattern. that was weird. in a good way.
Track everything. Even the small stuff. Like how you smiled at a dog today. That’s progress. No scale can measure that.
