What Is Citalopram?
Simply put, citalopram is a prescription medicine used to treat depression and other mood disorders. To understand how it helps, imagine your brain has tiny chemical messengers that control your happiness, calmness, and overall mood. One of the most important messengers is called serotonin.
When you experience depression, the normal flow and balance of serotonin inside your brain become disrupted. Citalopram works by increasing the amount of available serotonin in your brain. This helps lift your mood and restores a sense of emotional balance over time.
Citalopram belongs to a group of medicines called Selective Serotonin Reuptake Inhibitors, commonly known as SSRIs. While this medical name sounds complex, it simply refers to the way the medicine targets and boosts serotonin levels in your nervous system. In some cases, doctors may also prescribe this medicine for other health conditions.
Things to Tell Your Doctor Before Starting
Even though citalopram is a widely used and generally safe medicine, it can interact with other health conditions you might have. Before you start taking this medicine, you must tell your doctor if you have any of the following medical issues or personal circumstances:
| Medical Condition or Situation | Why Your Doctor Needs to Know |
|---|---|
| Bipolar disorder or family history | Antidepressants can sometimes trigger manic episodes, making accurate diagnosis essential. |
| Bleeding disorders or blood-thinning medicines | Citalopram may slightly increase your risk of abnormal bleeding or bruising. |
| Heart disease or irregular heart rhythms | The medicine can sometimes affect your heart electrical rhythm and heartbeat patterns. |
| Glaucoma (increased eye pressure) | This medicine can widen your pupils and worsen certain types of glaucoma. |
| Liver or kidney disease | Your body may process the medicine slower, requiring a lower dose. |
| Low sodium, magnesium, or potassium levels | Electrolyte imbalances can increase the risk of serious heart rhythm problems. |
| History of seizures or epilepsy | Though rare, antidepressants can lower your seizure threshold. |
| Thoughts of self-harm or suicide | Your doctor must monitor your mental health closely during the first few weeks of treatment. |
| Pregnancy or planning to get pregnant | Medical supervision is vital to weigh the risks and benefits for both you and your baby. |
| Breastfeeding an infant | Small amounts of the medicine can pass into breast milk and affect your baby. |
| Allergies to citalopram or other drugs | This ensures you do not experience a severe allergic reaction. |
How to Take Citalopram Properly
Using this medicine correctly is very simple, but following your doctor's instructions closely is essential for your safety and recovery.
- Swallow the capsule whole with a full glass of water.
- Never break, crush, chew, or open the capsule before swallowing.
- You can take this medicine with food or on an empty stomach.
- Try to take your dose at the exact same time every day. This keeps a steady level of medicine in your body and helps you remember your daily dose.
Important Safety Warning: Never stop taking citalopram suddenly on your own, even if you start feeling much better. Stopping abruptly can cause uncomfortable withdrawal symptoms and make your original condition return.
Special Patient Groups
Children and teenagers taking this medicine need close supervision from both family members and doctors. Young people may experience increased emotional changes or behavioral shifts.
Older adults aged 60 and above often process medicines differently. Doctors often prescribe a lower starting dose for older adults to reduce the risk of side effects like drowsiness or dizziness.
What to Do in an Overdose
If you or someone else takes more citalopram than prescribed, do not wait for symptoms to appear. This is a medical emergency.
Call emergency services right away at 911 (US/Canada), 999 (UK), or go straight to the nearest hospital emergency department (ER or A&E). If you are in Sri Lanka, contact the National Poisons Information Centre at the National Hospital of Sri Lanka.
Remember: Citalopram is prescribed specifically for you. Never share your medicine with friends, family members, or anyone else.
What to Do if You Miss a Dose
If you forget to take your daily dose, take it as soon as you remember. However, if it is almost time for your next scheduled dose, skip the missed dose entirely.
Simply continue with your normal schedule. Never take two doses at the same time to make up for a missed one.
Citalopram and Other Medicines
Citalopram can interact with various other drugs, changing how the medicine works or increasing your risk of side effects. Always give your doctor a complete list of every medicine, vitamin, and herbal product you use.
| Medicine or Substance Category | Potential Risk or Interaction |
|---|---|
| MAOI Antidepressants (e.g., Marplan, Nardil, Parnate) | Must never be taken with citalopram. This combination can cause a life-threatening condition called serotonin syndrome. |
| Other Heart Rhythm Drugs (e.g., Pimozide, Thioridazine) | Can cause dangerous irregular heartbeats when combined. |
| Alcohol | Can increase drowsiness, dizziness, and impair your judgment. Avoid alcohol while taking this medicine. |
| Pain Relievers (NSAIDs like Ibuprofen, Naproxen, Aspirin) | Combining these with citalopram raises your risk of stomach bleeding and bruising. |
| Blood Thinners (e.g., Warfarin, Enoxaparin) | Greatly increases bleeding risks. Your doctor will monitor your blood tests closely. |
| Other Mental Health Medicines or Supplements | St. John's wort and other SSRIs can cause dangerous serotonin buildup. |
Things to Watch While Taking Citalopram
As you take citalopram, keep these practical tips and safety guidelines in mind:
- Give it time: Do not expect instant results. It takes several weeks for your brain chemistry to adjust and for you to feel better.
- Attend check-ups: Visit your doctor for scheduled follow-up appointments to review your progress and adjust doses if necessary.
- Monitor mood changes: Especially during the first few weeks or after a dose change, watch for worsening depression or thoughts of self-harm. Share any worrying mood shifts with your doctor or a trusted family member right away.
- Be careful driving: Citalopram can cause dizziness or slow your reaction times. Avoid driving or operating machinery until you know how the medicine affects you.
- Manage dry mouth: Dry mouth is common. Sip water throughout the day or suck on sugar-free hard candies to keep your mouth comfortable.
Understanding Side Effects
Like all medicines, citalopram can cause side effects, though not everyone experiences them. Most common side effects are mild and tend to fade after the first couple of weeks.
| Side Effect Category | Symptoms & What to Do |
|---|---|
| Serious Side Effects (Call Doctor Right away) |
|
| Common Side Effects (Usually Mild) |
|
If any common side effect bothers you or does not go away, talk to your doctor. If you notice any serious warning signs, seek medical help right away.
