Can Citalopram Cause Hair Loss? | What The Evidence Shows

Yes, citalopram can be linked to hair shedding in some people, though it appears to be an uncommon side effect.

If you started citalopram and then noticed more hair in the shower, on your brush, or across your pillowcase, your concern is fair. Hair loss can feel personal in a way few side effects do. The good news is that this reaction does not appear to be common, and it often has more than one possible trigger.

The tricky part is timing. Hair shedding often shows up weeks after a trigger, so it is easy to blame the wrong thing. A new medicine may be part of the story. Stress, illness, weight change, thyroid issues, iron problems, and pattern hair loss can be in the mix too. That is why it helps to judge the whole picture instead of pinning everything on one pill right away.

Can Citalopram Cause Hair Loss? What The Label Says

Yes, it can. The strongest signal comes from the FDA-approved prescribing information for citalopram, which lists alopecia under skin and appendages disorders as an infrequent adverse reaction. In plain English, that means hair loss has been reported, but it sits in the uncommon range rather than among the side effects most people get.

That does not prove every case of shedding on citalopram comes from the drug. It does show the link is real enough to appear in the official label. So if your hair started thinning after you began treatment, the idea should not be brushed off.

At the same time, citalopram helps many people and may be doing a lot of good for your mood. Stopping it on your own can create a bigger mess than the shedding itself. A better move is to track what is happening, then bring a clean timeline to the prescriber who manages the medicine.

What Hair Loss From Citalopram Often Looks Like

When a drug plays a part in shedding, the pattern is often diffuse. That means your hair looks thinner all over rather than leaving one smooth bald patch. You may spot extra strands in the drain, more hair on your clothes, or a ponytail that feels less full.

Many cases fit a pattern close to telogen effluvium, a type of shedding that happens when more hairs shift into the resting phase and then fall out later. Cleveland Clinic’s telogen effluvium overview notes that this kind of loss usually causes heavy shedding and overall thinning instead of a sharply defined bare spot.

Clues That Point Toward A Medication Link

A medicine link becomes more believable when the timing lines up and no other strong cause jumps out. These clues help:

• The shedding began after citalopram was started or the dose changed.
• Your scalp looks normal, with no scaling, sores, or marked redness.
• The loss is spread across the scalp instead of forming round patches.
• The rest of your routine has stayed mostly the same.

None of those clues seal the case. They just raise the odds that the drug deserves a closer look.

Other Causes That Can Look Similar

This is where people get tripped up. Hair loss often has overlap. A person can start citalopram after a rough stretch, then notice shedding two months later. Was it the drug? The illness that came before it? A crash diet? A thyroid problem? Sometimes the answer is not one thing but two or three things landing at once.

That is why a simple list of dates helps so much: when citalopram started, when the dose changed, when the shedding began, and whether there was another event around the same window.

Possible Reason	What It Often Looks Like	Clue That Helps Sort It Out
Citalopram side effect	Diffuse shedding, thinner overall volume	Starts after the medicine begins or after a dose shift
Telogen effluvium	More hair in brush, shower, and on clothes	Often follows illness, fever, stress, childbirth, or weight loss
Female or male pattern loss	Gradual widening part or thinning at crown	Usually slower and more patterned than sudden shedding
Iron shortage	Diffuse thinning	May come with fatigue, pale skin, or heavy periods
Thyroid trouble	Dry hair, diffuse shedding	Cold or heat issues, weight change, bowel changes
Tight styles or chemical damage	Breakage or loss around hairline	Edges and stressed areas thin first
Alopecia areata	Smooth round patches	Patchy loss stands out from all-over shedding
Scalp disease	Loss with itch, scale, pain, or redness	Scalp changes point away from simple drug shedding

What To Do If Your Hair Starts Shedding

Start with a calm, boring record. That sounds dull, but it works. Take a few photos in the same light once a week. Note when the loss began. Write down dose changes, missed doses, new medicines, and big body stressors like a fever or a drop in weight.

Next, let your prescriber know what you are seeing. The MedlinePlus citalopram page says not to stop taking citalopram without talking to your doctor and notes that the dose is usually lowered bit by bit. That matters because a sudden stop can bring on a fresh set of problems.

You can make that visit more useful with a short checklist:

• When did the shedding start?
• Did it begin after starting citalopram or after a dose increase?
• Is the loss all over, or in patches?
• Any scalp itch, pain, scale, or rash?
• Any recent illness, weight loss, childbirth, or diet change?
• Any family history of patterned thinning?

If the story still points toward citalopram, your clinician may suggest waiting a bit longer, checking for other causes, lowering the dose, or switching to a different antidepressant. The right move depends on how well the drug is helping, how severe the shedding is, and whether another cause is staring you in the face.

The official FDA prescribing information for citalopram is useful here because it confirms alopecia has been reported, even though it is not a common reaction.

When A Switch May Be Worth Asking About

Sometimes the picture becomes clear enough that a medication change is worth a chat. That tends to happen when the shedding is steady, the timing fits, and no better cause turns up after review. It is easier to make that call when your mood has been stable and there is room to adjust treatment without losing ground.

Even then, there is no perfect antidepressant with zero trade-offs. A new drug may treat the hair issue but bring a different side effect. That is why the goal is not “find a pill with no downsides.” It is “find the best fit for your mood and your body.”

Situation	What Usually Makes Sense	Why
Mild shedding, mood much better	Track it for a short period	Some shedding settles once the trigger passes
Steady shedding with a clear drug timeline	Ask about dose review or a switch	The medicine link becomes harder to ignore
Patchy loss or inflamed scalp	Get the scalp checked	That pattern can point to another diagnosis
Shedding plus fatigue or weight change	Ask about lab work	Iron or thyroid issues may be part of it
Stopping the drug feels tempting	Do not quit cold turkey	Tapering is safer than a sudden stop

When To Get Checked Sooner

Hair shedding on its own is usually not an emergency, but some patterns deserve quicker care.

Red Flags That Need Prompt Attention

Reach out soon if the loss is sudden and patchy, your scalp is painful or inflamed, you see crusting or pus, your eyebrows or lashes are falling out too, or the hair loss is coming with other symptoms like marked fatigue, faintness, or fast weight change. Those details push the story away from plain medication shedding and toward something that needs a closer exam.

If citalopram is helping your mood, try not to let the fear of hair loss pull you into a rushed stop. A short call with the prescriber is usually the smartest next move.

What This Means For Most People

Citalopram can cause hair loss, but it seems to be uncommon. When it happens, it often looks like all-over shedding rather than a single bald patch. The toughest part is that hair loss has a long list of look-alikes, so timing and pattern matter a lot.

If you think citalopram is behind your shedding, keep a simple record, get your scalp and timing reviewed, and do not stop the medicine on your own. In many cases, there is a sensible fix once the real trigger is pinned down.
