NP Emma’s Top 5 Tips for Starting an Antidepressant
Written by: Emma Winson, MSCN, Nurse Practitioner
Starting an antidepressant can feel a bit like bringing home a mysterious new houseplant from Canadian Tire: you are hopeful, slightly suspicious, and wondering, “How long until I know this will live?”
First things first: needing medication is not a failure. It is healthcare. Your brain and body are part of the same ecosystem, and sometimes they need support beyond deep breathing, herbal tea, and pretending everything is fine will your dumpster catches fire.
Antidepressants are not “happy pills,” and they are not a personality transplant. They are one tool, among many, that can help support mental health, nervous system regulation, sleep, emotional resilience, and overall functioning. I have had patients tell me, “I finally know what it is like to feel normal.”
Whether you are starting your very first antidepressant or trying another medication after previous challenges, here are my top five tips to help set yourself up for success.
1. Before you ghost your antidepressant, let’s talk about the 3 common reasons people jump ship
One of my favourite teaching points with patients is this:
People commonly stop antidepressants for three reasons:
“It’s not working.”
“It’s working.”
“Ew, side effects.”
Ironically, all three are very common, and all three should usually lead to a conversation, not an abrupt medication change.
If it is not working, come back.
If it is working, great, keep taking it… and come back.
If the side effects are intolerable, start by consulting your pharmacist, then come back.
Please keep communication going during treatment changes. Reach out if you experience side effects, worsening symptoms, missed doses, medication concerns, or if you are tempted to stop or adjust your medication independently. Mental health treatment works best when it is collaborative.
And please, do not suddenly stop your antidepressant because you feel better, feel weird, or watch something alarming at 1:10 am on TikTok. Stopping abruptly can cause withdrawal symptoms and increase the chance of symptoms returning.
2. Give it time, your brain is not Amazon Prime, Click & Collect, or a Timmies Drive-Thru
Many antidepressants take a few weeks before you notice a meaningful shift. Early improvement may show up within 2 to 4 weeks, while fuller benefits can sometimes take 6 to 12 weeks, depending on your treatment.
You might notice sleep, appetite, energy, or emotional regulation improving before your mood fully catches up. That does not necessarily mean the medication is “not working.” It may mean your nervous system is slowly recalibrating.
That said, follow-up still matters.
When I start a new antidepressant, I generally want to know within about 3 weeks whether we are moving in the right direction. That does not necessarily mean the medication has reached its full effect yet, but we are usually looking for early clues:
Is anxiety improving even slightly?
Is sleep becoming more consistent?
Is focus, motivation, or emotional regulation improving?
Is the medication tolerable enough to continue?
Mental health medications often require adjustments. Sometimes we increase the dose. Sometimes we decrease it. Sometimes we switch medications entirely. Follow-up appointments are where we fine-tune treatment thoughtfully rather than leaving you stuck struggling alone.
3. Please do not freestyle your serotonin, your nervous system has been through enough plot twists
This sounds simple, but it makes a huge difference.
Some antidepressants are better tolerated with food. For example, Trintellix (vortioxetine) and Pristiq (desvenlafaxine) are often easier on the stomach when taken with food, especially during the first several weeks.
Other medications are best taken in the morning because they may feel more activating or stimulating, while some are better tolerated at night if they cause drowsiness.
Consistency matters. Taking medications randomly, skipping doses, doubling doses after forgetting, or changing the timing constantly can make it much harder to know whether a medication is actually helping or causing side effects.
If you are unsure how or when to take your medication, ask. Check the handout from your pharmacy, search for the official product monograph, talk to your pharmacist, or bump your appointment up to chat with me sooner. Small adjustments can sometimes make a big difference.
4. If your nervous system starts acting like an unsupervised Chihuahua driving a Cybertruck
Nausea, headaches, dry mouth, sleep changes, sweating, or feeling a bit “off” can happen early on. For many people, side effects improve after the first couple of weeks as the body adjusts. Again, proper timing of your medications can greatly mitigate these side effects.
But “common” does not mean “suffer through it forever.”
Many people only monitor for “bad” symptoms after starting an antidepressant, but it is equally important to notice subtle improvements too.
Sometimes the first sign that treatment is helping is:
Crying less often
Feeling less overwhelmed
Getting out of bed more easily
Reduced irritability
Sleeping through the night
Better concentration
Less panic
Feeling emotionally “lighter”
At the same time, it is important to monitor for worsening mood, increased anxiety, agitation, emotional blunting, panic symptoms, insomnia, impulsivity, or suicidal thoughts, particularly during the first several weeks of treatment changes.
If something feels significantly worse, do not wait silently.
5. Your antidepressant should not be carrying the whole group project
At Acceptance, the goal is never simply to prescribe an antidepressant and send you on your way.
Mental health symptoms are deeply connected to sleep, hormones, stress, trauma, burnout, neurodivergence, relationships, physical health, and life circumstances.
Medication can absolutely help, but it is rarely the whole story.
Good mental health care should feel collaborative, individualized, supportive, and thoughtful. This also means having the right therapist on your side. At Acceptance, our RN Psychotherapists are nurses first and can support you in a unique way that you may not have experienced with other counselling providers.
And perhaps most importantly:
You should never feel like you are navigating it alone.

Before you celebrate your happily ever after let’s review my 5 tips!
Before discontinuing an antidepressant, it is important to remember that people commonly stop medications because they feel the medication is not working yet, because they are feeling better, or because side effects become difficult to tolerate, but all three situations should lead to a conversation rather than an abrupt medication change.
Antidepressants often require a bit of time before meaningful improvement is seen, which is why follow-up appointments are important.
Taking medications consistently, at the appropriate time of day, and with food when recommended can significantly improve both effectiveness and tolerability.
Some side effects and temporary changes can occur early in treatment, but patients should also watch for subtle improvements.
Mental health treatment is about more than medication alone, and effective care should also consider the broader context of a person’s life, including concurrent psychotherapy.
You deserve mental health care that feels collaborative, supportive, and personalized. Let’s talk about what that could look like for you.
