Citalopram, commonly sold under the brand name Celexa, is a type of antidepressant known as a selective serotonin reuptake inhibitor (SSRI). SSRIs are among the most commonly prescribed antidepressants today because they’re generally effective and have fewer side effects than older antidepressants.
Citalopram works by increasing the amount of serotonin—a neurotransmitter that helps regulate mood—in the brain. By blocking the reabsorption of serotonin, citalopram helps improve mood, reduce anxiety, and restore emotional balance.
The FDA approved citalopram in 1998 for the treatment of major depressive disorder. It’s one of the most selective SSRIs, meaning it primarily affects serotonin with minimal impact on other neurotransmitter systems.
Together, you and your provider can determine if citalopram is the right choice for your treatment.
No. Project Semicolon is not a medical provider and we can’t recommend, prescribe, diagnose, or tell you what medication is “right” for you. A licensed clinician and/or pharmacist is the best person to guide medication decisions based on your health history and needs.
Only a qualified prescriber can help you decide. Many people use medication, therapy, lifestyle supports, or a combination. If you’re considering medication, a good first step is talking with a primary care provider, psychiatrist, or another licensed prescriber.
Helpful questions include: What is this medication for? What benefits should I look for—and when? What are common side effects? What are serious symptoms I should report immediately? Are there interactions with other medications, supplements, alcohol, or cannabis? What’s the plan if it doesn’t help?
Be as specific as you can: what you’re feeling, when it started, how intense it is, and whether anything changed (dose, timing, other meds, sleep, alcohol, etc.). If possible, keep a short log for a few days. You can ask: “Is this expected?” “How long should I wait?” “When should I contact you urgently?” and “Are there alternatives or dose adjustments that could help?”
Some side effects can be mild and temporary as your body adjusts. Others can be serious and need prompt medical attention. If you’re unsure, it’s always okay to call your prescriber or pharmacist and ask. If symptoms feel severe, rapidly worsening, or scary, seek urgent care right away.
It depends on the medication and the person. Some changes (like sleep or appetite) may shift sooner, while mood or anxiety improvements can take longer. Your prescriber can tell you what timeline is typical for the specific medication you’re taking.
You’re not alone—this can happen, and it’s important to tell your prescriber as soon as possible. Don’t change your dose or stop the medication without guidance unless you’ve been instructed to do so. If you feel unsafe or like you might hurt yourself, seek immediate help right now.
Talk to your prescriber first. Some medications should be tapered rather than stopped suddenly, and your provider can help you make a safe plan. Feeling better is a good sign—but it doesn’t always mean it’s time to stop.
Follow the instructions on your prescription label or ask your pharmacist what to do. In general, avoid doubling up unless a professional specifically tells you to. If missed doses happen often, ask about strategies or a schedule that fits your life.
Yes—changes in sleep, appetite, energy, and libido are common topics, and they’re worth bringing up. If something feels uncomfortable or disruptive, ask your prescriber about adjustments, timing changes, dose changes, or alternatives.
You still have options. Community clinics, sliding-scale services, and telehealth providers can be a starting point. Pharmacists can also answer many medication questions. This page can help you learn what to ask—but it can’t replace individualized medical care.
