Acitretin is a second‑generation oral retinoid prescribed primarily for severe psoriasis. It works by normalising skin cell growth and reducing inflammation, but its long half‑life (up to 100days) and strong teratogenic potential demand a careful discontinuation plan.
Why You Might Need to Stop Acitretin
Patients stop the drug for several reasons: liver enzyme elevation, troublesome lipid spikes, pregnancy plans, or simply because a newer therapy (such as a biologic) offers better control. Knowing the underlying trigger helps you and your dermatologist choose the right tapering speed and replacement.
Step1: Get Baseline Lab Results
Before any dose reduction, order a full panel:
- Liver function tests (ALT, AST, ALP, bilirubin) - Acitretin can raise transaminases.
- Lipid profile - triglycerides often jump 30‑50%.
- Serum retinol levels - to gauge vitaminA storage.
- Pregnancy test (if applicable) - mandatory for women of child‑bearing potential.
Document the numbers in a simple table for future comparison:
| Test | Result | Reference Range |
|---|---|---|
| ALT | 45U/L | 7‑56U/L |
| AST | 38U/L | 5‑40U/L |
| Triglycerides | 210mg/dL | ≤150mg/dL |
| Retinol | 1.2µg/mL | 0.8‑2.0µg/mL |
| β‑hCG (women) | Negative | Negative |
Step2: Review Contraception & Teratogenic Risk
Acitretin’s teratogenic window extends up to three years after the last dose because it can be re‑esterified to isotretinoin. Women must use two reliable forms of birth control (e.g., hormonal pill + condom) throughout treatment and for at least three years after stopping. Talk to a family‑planning specialist if you’re unsure about compliance.
Step3: Choose a Tapering Schedule
Because Acitretin sticks around for months, a sudden stop isn’t ideal if you’ve been on a high dose (≥50mg/day). A typical taper looks like this:
- Reduce from full dose to 50% for 4-6 weeks.
- Cut to 25% for another 4 weeks.
- Switch to an alternate therapy (e.g., methotrexate or a biologic) during the final taper.
Adjust the timeline if liver enzymes or lipids rise; a slower reduction gives your body time to normalise.
Step4: Monitor Labs During Taper
Repeat the panel every 4‑6 weeks. Look for two trends:
- ALT/AST returning to baseline (ideally <30U/L).
- Triglycerides dropping below 150mg/dL.
If values plateau or worsen, pause the taper and discuss a switch to a non‑retinoid option.
Step5: Transition to an Alternative Therapy
Choosing the next line depends on disease severity and patient preference. Below is a quick comparison.
| Attribute | Acitretin | Methotrexate | Biologic (Adalimumab) |
|---|---|---|---|
| Route | Oral | Oral | Subcutaneous injection |
| Onset (weeks) | 4‑8 | 6‑12 | 2‑4 |
| Major side‑effects | Liver, lipids, teratogenic | Liver, marrow suppression | Infection risk, injection site reactions |
| Pregnancy safety | Contra‑indicated | Contra‑indicated | Generally safe after 1‑month washout |
| Cost (UK, 2025) | £30/month | £20/month | £250/month |
For many patients, a biologic offers faster clearance with fewer metabolic worries, but the price tag is higher. Discuss insurance coverage and personal budget with your clinician.
Step6: Manage Residual Skin Symptoms
Even after the drug leaves your system, plaques can linger. Topical corticosteroids, vitaminD analogues, or phototherapy are useful bridges. Keep a symptom diary to show your dermatologist which adjuncts work best.
Step7: Long‑Term Follow‑Up
Because Acitretin’s metabolites may stay detectable for up to three years, schedule a final check‑in at 12months post‑cessation. Verify that liver enzymes, lipid profile, and retinol are stable. If you’re planning pregnancy, confirm a negative β‑hCG and a normal ultrasound before trying to conceive.
Related Concepts and Next Steps
Understanding how Acitretin fits into the broader retinoid family helps you anticipate cross‑reactivity. Isotretinoin, for instance, is a potent acne retinoid with a similar teratogenic profile but a shorter half‑life. If you ever need to switch back to a retinoid for a different skin condition, the same safety checklist applies.
Looking ahead, you might explore the following topics:
- Biologic‑first strategies for psoriasis - how newer agents outperform oral retinoids.
- Managing drug‑induced dyslipidaemia - lifestyle tweaks and statin use.
- Pregnancy planning after retinoid exposure - timelines and counseling.
Each of these pieces builds on the safe discontinuation framework you just learned.
Frequently Asked Questions
How long does Acitretin stay in the body after the last dose?
Acitretin’s elimination half‑life ranges from 49 to 100days. Because it can be reconverted to isotretinoin, detectable levels may persist for up to three years, which is why strict contraception is required for that entire period.
Do I need to taper if I’ve only been on a low dose?
If you’ve taken ≤10mg/day for less than six months and labs are stable, some clinicians may allow a direct stop. However, a short 2‑week taper is still advisable to avoid sudden spikes in liver enzymes or lipids.
Can I switch to isotretinoin for acne after stopping Acitretin?
Only after confirming a negative pregnancy test and waiting at least three months (or longer if you’ve been on high‑dose Acitretin). Discuss the plan with both your dermatologist and a dermatologist‑specialist in acne.
What are the most common side‑effects that trigger discontinuation?
Elevated liver enzymes (ALT/AST>3× upper limit), triglycerides >300mg/dL, severe mucocutaneous dryness, and any pregnancy‑related concerns are the top reasons clinicians advise stopping.
Is it safe to become pregnant shortly after stopping Acitretin?
No. The drug’s teratogenic risk persists for up to three years. Women must use effective contraception throughout that window and obtain clearance from a specialist before attempting conception.
How do I handle a flare‑up during the taper?
Temporarily pause the dose reduction and add a fast‑acting topical steroid or phototherapy. If flares persist, discuss an earlier switch to a biologic rather than continuing the taper.

Just stopped acitretin last month after 18 months. Tapered slow like they said-50% for 6 weeks, then 25%. Skin flared up bad but phototherapy saved me. No more dry lips or cracked heels. Best decision ever.
Thanks for this. I’ve been nervous about quitting because my doc just said ‘stop it’ and left it at that. This step-by-step stuff actually makes me feel like I’m not going to turn into a human lizard overnight.
Let’s be real-acitretin is basically vitamin A on steroids with a side of existential dread. The half-life isn’t just long, it’s a ghost that haunts your lipid panel for years. I’ve seen patients come back 2 years later with triglycerides at 800 because they thought ‘it’s out of my system’-nope. It’s in your fat cells, whispering sweet nothings to your liver. And don’t even get me started on the re-esterification to isotretinoin. That’s not a side effect, that’s a biological betrayal. If you’re planning pregnancy, you need more than a calendar-you need a forensic toxicologist and a very stern therapist.
This is gold. I was terrified to come off it after 3 years, but following this exact plan-baseline labs, slow taper, biologic bridge-I went from scaly monster to human again. My triglycerides dropped from 310 to 140 in 5 months. You don’t need to suffer in silence. There’s a path. Follow it.
Of course they say ‘wait 3 years’-that’s what Big Pharma wants you to believe. Meanwhile, the FDA quietly approved isotretinoin for men in 2021 and now they’re just extending the myth to acitretin. I’ve got friends who got pregnant 8 months out and had perfectly healthy babies. They just didn’t tell their doctors. You’re being manipulated.
My dermatologist never mentioned the re-esterification risk. I thought three months was enough. I’m 11 months out now and still terrified to even think about trying. This post saved me from a potential disaster. Thank you.
Step 1: Get baseline labs? How quaint. My doctor didn’t even check my ALT until I turned yellow. Step 2: Contraception? Yeah right, like anyone’s using two methods when they’re on this drug. Step 3: Taper? Nah. I just stopped. My skin’s fine. My liver? Eh. Who cares. You’re overthinking this.
The clinical rigor of this guide is commendable. The inclusion of quantitative baseline metrics and clear temporal milestones demonstrates a thoughtful, evidence-based approach to discontinuation protocols. One might argue that the teratogenic window remains underemphasized in general practice.
Why are we still using acitretin when biologics exist? It’s like using a horse-drawn cart to deliver a package across the country. The tapering protocol is just damage control for a drug that should’ve been retired in 2010.
I’m so glad someone wrote this. I was so anxious about stopping-I felt like I was giving up. But this made me feel like I was taking control. Thank you for the clarity.
I’ve been on acitretin for 5 years. I tapered over 9 months, switched to secukinumab, and my skin’s never been better. But the emotional toll? That’s the part no one talks about. You feel like you’re losing a part of yourself when you stop-it’s not just skin, it’s identity. I cried the day I took my last pill. I didn’t know I’d miss the routine, the predictability, even the side effects. It’s like grieving a toxic relationship you finally left.
While the guidance presented is methodologically sound, I must respectfully emphasize that the teratogenic risk window of three years is not merely a recommendation-it is an absolute contraindication under current FDA labeling and international teratology guidelines. Any deviation from this standard constitutes a clinically significant risk and may constitute negligence in reproductive counseling. Further, the use of colloquial language in clinical documentation may compromise the integrity of informed consent processes. I urge all practitioners to adhere strictly to established protocols and to avoid informal phrasing in patient-facing materials.
