How Does Celexa Affect Your Body?
Celexa contains citalopram, a selective serotonin reuptake inhibitor (SSRI) approved to treat major depressive disorder in adults. It is closely related to Lexapro, but Lexapro contains escitalopram, a different medication with different recommended dosing limits.
Most citalopram side effects in women are the same ones men experience, and many show up before your mood starts to improve. A few deserve closer attention for women in particular, especially changes in sexual health, menstrual bleeding, and heart rhythm. Knowing which side effects are expected and which are warning signs makes it easier to decide what can wait for your next appointment and what can’t.
What Are the Common Side Effects of Celexa?
The most common side effects of Celexa in women are digestive upset, sleep changes, and increased sweating. Most appear during the first few weeks of treatment, and several ease as your body adjusts.
Nausea and Digestive Changes
Celexa may cause nausea, diarrhea, or occasional vomiting, especially when starting treatment. Dry mouth is another common complaint and can make eating or speaking uncomfortable.
Sleep Problems and Fatigue
Some women have difficulty sleeping, while others feel unusually sleepy or tired during the day. Dizziness and lightheadedness can also occur, especially early in treatment.
Because fatigue and sleep changes can also be symptoms of depression, noting when they began can help your clinician tell whether the medication is contributing.
Increased Sweating
Celexa can cause excessive sweating, including night sweats that may leave you waking up damp or uncomfortable. Unlike nausea, sweating often continues for as long as you take the medication.
How Does Celexa Affect Your Sex Drive or Ability to Orgasm?
Celexa sexual side effects in women most often show up as lower desire or more difficulty reaching orgasm. Some women notice these changes even while their depression is improving, which can be confusing when other parts of life are beginning to feel more manageable.
Depression itself can lower sexual interest and satisfaction, so it helps to compare where things stood before treatment. If intimacy felt comfortable before you started Celexa and has changed noticeably since, that timing points toward the medication.
Sexual side effects are common, and they are a legitimate reason to talk with your prescriber. You don’t have to quietly put up with them.
Does Celexa Affect Your Period or Cause Unusual Bleeding?
Celexa can make periods more painful for some women and can raise the risk of heavier bleeding, but it isn’t known to routinely disrupt your cycle. Painful periods, known as dysmenorrhea, were reported in 3% of women taking Celexa compared with 2% receiving a placebo in pooled clinical trials.
The bleeding risk comes from how SSRIs affect platelets, the cells that help blood clot. This matters if you regularly take ibuprofen, naproxen, or aspirin for menstrual cramps, since those medications add to the same risk. Unexpectedly heavy periods or unexplained bruising are worth raising with your doctor.
Not every cycle change traces back to Celexa. Stress, hormonal shifts, gynecological conditions, and other medications can all play a role. The available evidence doesn’t show that citalopram routinely disrupts reproductive hormones, so persistent changes deserve an individualized evaluation.
Will Celexa Side Effects Go Away on Their Own?
Early Celexa side effects, particularly nausea and some sleep disturbances, often begin to improve within the first couple of weeks. Others, such as increased sweating or sexual difficulties, may continue even after the medication begins helping with depression.
The side effects of Celexa in women don’t always follow a predictable schedule. You might feel more physically comfortable before noticing mood improvements, or find that one persistent symptom keeps affecting your daily life even though the medication is otherwise working.
If a side effect becomes difficult to manage, your prescriber has options. Depending on your symptoms and how you respond, they may recommend changing when you take Celexa, adjusting your dose, or switching to another medication. You don’t need to make those changes on your own or wait until a symptom feels unbearable before bringing it up.
Which Celexa Side Effects Are Serious?
Serious side effects of Celexa in women are uncommon, but they need prompt medical attention. The most important ones involve your heart rhythm, bleeding, serotonin levels, sodium levels, and mood.
Heart Rhythm Changes
Citalopram can prolong the QT interval, a measurement of how the heart’s electrical system resets between beats. In rare cases, this can contribute to a serious abnormal heart rhythm.
The risk rises with higher doses. The maximum recommended dose is 40 mg daily for most adults, but it is limited to 20 mg daily for some individuals, including adults older than 60, people with liver impairment, and those taking certain interacting medications.
There’s also a consideration specific to women. The American Heart Association identifies female sex as a risk factor for a rare drug-induced rhythm disturbance called torsades de pointes. Low potassium or magnesium levels, existing heart conditions, and other medications that affect heart rhythm can increase that risk. Depending on your medical history, your clinician may recommend an electrocardiogram (ECG) or blood tests to check electrolyte levels.
New or significant palpitations, a fast or irregular heartbeat, or feeling faint need prompt medical evaluation.
Other Reactions That Need Prompt Care
- Unusual Bleeding: Unexpected heavy bleeding, black stools, or vomiting blood may indicate a serious bleeding problem.
- Serotonin Syndrome: High fever, confusion, agitation, rapid heartbeat, or muscle stiffness and twitching can signal a dangerous reaction.
- Low Sodium Levels: New confusion, severe weakness, or unsteadiness may indicate low sodium, particularly in older adults.
- Mood or Behavior Changes: New suicidal thoughts, severe agitation, or unusually high energy with very little sleep need prompt assessment.
- Severe Allergic Reactions: Swelling of the face, lips, or throat, especially with breathing difficulties, requires emergency care.
The FDA warns that antidepressants may increase suicidal thoughts and behaviors in children, adolescents, and young adults, particularly when starting treatment or changing doses. New suicidal thoughts deserve attention at any age.
Is It Safe to Take Celexa With Other Medications?
Some medications, supplements, and alcohol can increase Celexa’s side effects or cause potentially serious interactions. The risk depends on what you’re taking, your dose, and your medical history.
- Alcohol: Drinking while taking Celexa may worsen drowsiness, dizziness, and difficulty concentrating.
- Pain Relievers and Blood Thinners: Ibuprofen, naproxen, aspirin, and anticoagulants increase the risk of bleeding with citalopram.
- Medications and Supplements That Affect Serotonin: Other antidepressants, tramadol, certain migraine medications, and St. John’s wort may increase the risk of serotonin syndrome.
- Medications That Affect Citalopram Levels or Heart Rhythm: Omeprazole and certain heart medications can raise citalopram levels or the risk of abnormal heart rhythms.
Before starting a new medication or supplement, check with your prescriber or pharmacist. Bring a complete list of everything you take, including over-the-counter products, so they can spot interactions and decide whether changes are needed.
How Does Fullbrook Help When Depression and Substance Use Overlap?
Managing depression also means noticing how alcohol or other substances have worked their way into daily life for some women.

FAQs About Celexa Side Effects in Women
Does Celexa cause weight gain or weight loss?
Both weight gain and weight loss can occur during treatment. In short-term clinical trials, people taking Celexa lost an average of approximately 0.5 kg (1.1 pounds), but weight may change differently over time as appetite, depression symptoms, and daily routines change.
Why does Celexa make me yawn so much?
Frequent yawning is a documented Celexa side effect, and clinical trials found that it became more common at higher doses. It can occur even when you’re not particularly tired, although changes in sleep and other health factors may also contribute.
