Isotretinoin
Eravacycline
How we grade severity & evidence
Severity levels
- Contraindicated: These should generally not be used together.
- Major: Potentially serious — often needs a change or close monitoring.
- Moderate: Can be significant — usually manageable with monitoring.
- Minor: Usually limited clinical impact.
Evidence grades
- Established: Well documented — supported by controlled studies or strong clinical data.
- Probable: Good supporting evidence, though not definitively proven.
- Suspected: Some evidence suggests this interaction, but it is not well established.
- Possible: Limited or conflicting evidence; the interaction may occur.
- Theoretical: Predicted from the drugs' pharmacology; not yet confirmed in people.
Ratings come from the documented interaction literature and are reviewed by a pharmacist. They describe the documented risk of the combination, not what will necessarily happen to you — your dose, timing, and health picture all matter.
Taking these two together can raise pressure inside your head. Isotretinoin (Accutane) is a strong acne medicine, and eravacycline (Xerava) is an antibiotic in the tetracycline family. Both, on their own, can occasionally cause a rare condition called pseudotumor cerebri, which is basically increased pressure around the brain. When used together, that risk can add up.
Watch for warning signs like a bad or constant headache, nausea or vomiting, blurry or double vision, or other vision changes. If you notice any of these, contact your care team right away. This combination is usually avoided, so your doctor or pharmacist can help you find a safer plan.
Interaction: Concurrent oral retinoid (isotretinoin) and tetracycline-class agent (eravacycline) use carries an additive risk of pseudotumor cerebri / benign intracranial hypertension.
- Mechanism: Additive toxicity; both agents independently associated with intracranial hypertension (not a PK/enzyme interaction).
- Direction: Increased risk of a shared adverse effect (neither is a prodrug affected here).
- Evidence: Theoretical; severity rated major. Onset unspecified.
- Management: Avoid concomitant use. Monitor for papilledema, headache, nausea/vomiting, and visual disturbances; evaluate for pseudotumor cerebri if symptoms arise and consider alternative therapy.
What happens
An increased risk of pseudotumor cerebri (benign intracranial hypertension)
Interaction Deep Dive
Taking oral retinoids together with tetracyclines raises the likelihood of pseudotumor cerebri/intracranial hypertension, so this combination should not be used1. Anyone presenting with papilledema, headache, nausea and vomiting, or visual disturbances should undergo assessment for pseudotumor cerebri2.
Why it happens (mechanism)
Additive toxicity
How to manage this interaction
This combination is generally avoided. Because both drugs can independently raise pressure inside the skull, your care team will usually look for an alternative rather than use them together.
- Keep taking any medicine exactly as prescribed and do not stop on your own.
- Ask your pharmacist or prescriber whether a different antibiotic or acne treatment is appropriate.
- Report promptly any persistent headache, nausea or vomiting, or vision changes (blurred/double vision).
- Your team may examine your eyes for papilledema and evaluate you if symptoms appear.
Management is individual — confirm any change with your pharmacist or prescriber.
Literature reports
1 report — tap to read
a) A 14-year-old male receiving treatment for acne with isotretinoin 40 mg daily along with tetracycline 500 mg daily developed reduced visual function in both eyes three weeks after beginning the combined therapy. Prior use of isotretinoin alone and tetracycline alone had not produced any problems in this patient. The condition was diagnosed as pseudotumor cerebri. He received oral acetazolamide 1000 mg daily and prednisone 60 mg daily, yet still needed bilateral optic nerve sheath decompression. Eight months afterward, his visual acuity was 20/20 but he continued to have a visual field defect in both eyes 3.
Common questions
Can I take Eravacycline and Isotretinoin together?
Isotretinoin and eravacycline together can add up to increase the risk of dangerous pressure around the brain, so this combination is usually avoided; contact your care team about an alternative and report any severe headache or vision changes right away. Always confirm with your pharmacist or prescriber before making any change.
How serious is the Eravacycline and Isotretinoin interaction?
