🔑 Key Takeaways
- Citalopram is a prescription antidepressant that helps balance a natural chemical called serotonin in your brain.
- It can take several weeks of daily use before you start feeling the full emotional and physical benefits.
- Never stop taking your medicine suddenly without talking to your doctor first to avoid withdrawal effects.
- Always share your complete medical history and a list of all your other medicines with your doctor.
What Is Citalopram?
Citalopram is a prescription medicine used mainly to treat depression and other mood disorders. It belongs to a popular family of medicines known as SSRIs, which stands for Selective Serotonin Reuptake Inhibitors.
Think about how your brain controls your daily moods, thoughts, and energy levels. Your brain uses tiny chemical messengers called neurotransmitters to send signals back and forth. Serotonin is one of these vital chemicals that helps keep your mood steady and positive.
When you struggle with depression, your brain might have lower levels of active serotonin than it needs. Citalopram steps in to help keep more serotonin available in your brain. This boost helps lift your mood over time and makes daily life feel more manageable.
Things to Tell Your Doctor Before Starting Citalopram
Before you take your first dose, your doctor needs a complete picture of your health history. Certain medical conditions and past experiences can change how Citalopram acts in your body. Let your doctor know right away if any of these conditions apply to you.
| Your Health Condition or Habit | Why It Matters for Your Safety |
|---|---|
| Mental Health History | History of bipolar disorder, panic attacks, or past thoughts of self-harm or suicide. |
| Heart Problems | Any past heart disease, slow heartbeat, or abnormal heart rhythms like QT prolongation. |
| Organ Health | Existing kidney disease, liver disease, glaucoma, thyroid disorders, or a history of seizures. |
| Bleeding Risks | Taking blood thinners, bleeding disorders, or having low blood levels of sodium, potassium, or magnesium. |
| Allergies | Any past allergic reaction to Citalopram, Escitalopram, or other dyes, foods, or medicines. |
| Pregnancy and Nursing | If you are pregnant, planning to become pregnant soon, or currently breastfeeding your baby. |
How to Take This Medicine Correctly
Getting the best results from your treatment depends on taking your medicine exactly as directed. Consistency helps keep a stable level of the medicine in your bloodstream.
- Swallow your tablet whole with a full glass of water. You can take it with or without food.
- Try to take your medicine at the exact same time every single day to build a steady routine.
- Never take more than the exact dose prescribed by your doctor. More is not better and can be dangerous.
- If you forget a dose, take it as soon as you remember. If it is almost time for your next scheduled dose, skip the missed dose entirely and stay on your normal schedule.
- Never take two doses at the same time to make up for a missed tablet.
Crucial Safety Warning: Never stop taking Citalopram suddenly on your own. Stopping abruptly can cause uncomfortable withdrawal symptoms like dizziness, nausea, headaches, and intense mood swings. If you need to stop, your doctor will help you slowly lower your dose over several weeks.
What to Do If You Take Too Much
If you think you or someone else took more Citalopram than prescribed, you must act fast. Do not wait for symptoms to appear. Call your local emergency services right away. In the US or Canada, call 911. In the UK, call 999. You can also contact your local poison control center or go straight to the nearest hospital emergency room.
