What Is Fetzima

Drug class and purpose

Fetzima (levomilnacipran) belongs to the SNRI familyserotoninnorepinephrine reuptake inhibitors. It's FDAapproved for adults with major depressive disorder (MDD). Think of it as a gentle "reset button" for the brain chemicals that influence mood.

Why doctors prescribe it

When traditional SSRIs don't quite hit the mark, many clinicians turn to an SNRI like Fetzima because it targets two neurotransmitters instead of one. Studies show it can improve energy, focus, and mood more quickly for some people.

Expert insight

According to a boardcertified psychiatrist quoted in Mayo Clinic's overview, "Choosing an SNRI can be a strategic move for patients who need a boost in both serotonin and norepinephrine."

Realworld story

John, a 42yearold graphic designer, started Fetzima at a low dose after his therapist suggested trying an SNRI. Within three weeks he noticed his foggy mornings cleared up, and his anxiety eased enough to focus on his projects again.

Fetzima Strengths

Approved capsule strengths

Strength	Imprint	Typical packaging
20mg	FL20	220mg + 2640mg (titration pack)
40mg	FL40
80mg	FL80
120mg	FL120

Extendedrelease design

The capsule's coating is engineered to release the medication slowly over 24hours. That's why you must swallow it wholecrushing it can cause a rapid spike in drug levels, leading to uncomfortable side effects.

Dosing Schedule

Initial titration

Most doctors start low to see how your body reacts:

• Days12: 20mg once daily.
• Day3 onward: increase to 40mg once daily.
• If needed, add 40mg every 2days, up to a max of 120mg.

Maintenance range

After titration, the sweet spot usually lands between 40 and 120mg taken once each day. Your prescriber will aim for the lowest dose that eases your depression without unwanted side effects.

Maximum dose with CYP3A4 inhibitors

If you're on a strong CYP3A4 inhibitor such as ketoconazole, the ceiling drops to 80mg daily. This helps avoid toxic buildup of the drug.

Sample titration table

Day	Dose (mg)	Reason
12	20	Start low, assess tolerance
34	40	Standard therapeutic dose
56	80	If response insufficient and tolerable
7+	120	Maximum recommended dose (if needed)

How To Take

Administration tips

• Swallow the capsule wholeno chewing, splitting, or opening.
• You can take it with food or on an empty stomach; just pick what feels best for you.
• Pick a consistent time each day (morning is popular, but evenings work if it makes you sleepy).

Special Populations

Renal impairment

CrCl (mL/min)	Recommended max dose
60 (mild)	No adjustment; up to 120mg
3059 (moderate)	80mg daily
1529 (severe)	40mg daily
<15 (ESRD)	Not recommended

Hepatic function

Fetzima isn't heavily processed by the liver, so dose changes aren't usually needed for mild to moderate liver issues.

Elderly patients

Older adults may be more sensitive to side effects like low sodium (hyponatremia) or dizziness. Starting at 20mg and moving up slowly is the safest route.

Pregnancy & lactation

Data are limited, so you'll need a candid conversation with your OBGYN. The FDA label notes the risks and benefits must be weighed carefully.

Professional recommendation

According to the FDA prescribing information, "use during pregnancy only if the potential benefit justifies the potential risk to the fetus."

Drug Interactions

Major interactions

• MAOIs: Must be stopped 14days before starting Fetzima and viceversa (7days after stopping Fetzima).
• Strong CYP3A4 inhibitors (e.g., ketoconazole): Limit dose to 80mg.
• Other serotonergic agents (SSRIs, tramadol, linezolid, StJohn'swort): Risk of serotonin syndromemonitor closely.
• Anticoagulants/antiplatelets: May increase bleeding risk; regular labs recommended.

Contraindications

Fetzima isn't recommended for anyone with a history of bipolar disorder (it can trigger mania) or for patients with endstage renal disease.

Interaction quickreference table

Interaction type	Example	Action
MAOI	Phenelzine	Discontinue MAOI 14days before starting
Strong CYP3A4 inhibitor	Ketoconazole	Max 80mg/day
Antiplatelet	Aspirin, warfarin	Monitor bleeding, consider dose tweak
Serotonergic OTC	StJohn'swort	Avoid combination

Side Effects

Common adverse effects

Most people notice mild nausea, dry mouth, sweating, constipation, or reduced libido. These often fade after a couple of weeks as your body adapts.

Serious warnings

• Serotonin syndrome (agitation, rapid heartbeat, high fever) seek medical help immediately.
• Hyponatremia especially if you're older or on diuretics.
• Elevated blood pressure keep an eye on your readings.

Current dose	Reduce to	Duration
120mg	80mg	12weeks
80mg	40mg	12weeks
40mg	20mg	12weeks
20mg	Stop	About 1week

Talk To Doctor

Before you start, gather a list of everything you're takingincluding vitamins, herbal supplements, and overthecounter meds. Bring up these topics:

• Any history of bipolar disorder or mania?
• Current kidney or liver test results?
• Other meds that might interact (especially MAOIs or strong CYP3A4 inhibitors)?
• Preferred time of day to minimize side effects?

Ask for a written titration plan. Seeing the schedule on paper (or in a phone note) can reduce anxiety and help you stay on track.
