Steroid-sparing medicines: cyclosporine drops and tacrolimus
Ocular-surface immunomodulation · prescription-class education · not a purchase pitch

Key points
- Steroid-sparing education covers classes such as ciclosporin drops and tacrolimus — not a purchase pitch.
- Eyelid tacrolimus is often off-label: not as eye drops; generally not used under age two.
- Sudden vision drop or severe pain with headache/vomiting: A&E now.
- Worse pain, sudden vision drop or pus-like discharge on treatment: stop and seek same-day care when possible.
What it is
“Steroid-sparing”: when ocular-surface or eyelid inflammation needs longer control, a doctor may add non-steroid topical immunomodulators to lower the risks of long-term glucocorticoids (raised pressure, cataract, infection — see the steroid eye-drops page). Two classes: (1) cyclosporine eye drops / ophthalmic emulsion; (2) tacrolimus ointment on the eyelids (mostly dermatology-registered in Hong Kong; eyelid use is usually off-label). Not over-the-counter self-care; during active infection, do not add immunosuppression yourself.
Cyclosporine
Education on mechanism: dampens some T-lymphocyte–related inflammation. Onset often takes weeks. Stinging or burning on instillation is common. Active infection usually means stop — the doctor decides.
Cyclosporine eye preparations are a prescription immunomodulator class. Suitability and which product to use are decided by the treating doctor and the current label / Hong Kong registration status. This page lists no trade names, registration numbers, manufacturers, prices, shops or purchasing help, and makes no efficacy comparison or guarantee.
In EU and similar public information, some cyclosporine ophthalmic emulsions are described for adults with dry eye disease and severe keratitis not improved by tear substitutes — Hong Kong follows the local label.
Important distinction: overseas, other same-strength cyclosporine emulsions may be registered for severe VKC and related uses — do not write a Hong Kong dry-eye cyclosporine emulsion / drop as Hong Kong–approved therapy for severe VKC. Cyclosporine-class use in VKC/AKC may be off-label or a different product. No brand efficacy ranking.
Tacrolimus on the eyelids
Mainly dermatology-registered in Hong Kong; controlling AKC-related eyelid inflammation is usually off-label. Do not put it in the eye as drops; do not self-buy for the eyes; generally not used under age two. This page states no strength, frequency or course. Early burning is common; severe pain, sudden vision drop, herpes-like blisters or purulent discharge → stop and seek care. Label malignancy-risk concerns (causality not fully established). Small studies compared eyelid tacrolimus vs steroid ointment for AKC-related eyelid eczema — not a personal guarantee.
Use categories (education, not your prescription)
| Direction | Education note |
|---|---|
| Cyclosporine drops / emulsion | Prescription immunomodulator; onset often weeks. Indication and suitability follow the local label and the doctor (not a purchase pitch). |
| VKC / AKC ocular surface | May be off-label or a different overseas product; do not treat a HK dry-eye cyclosporine emulsion / drop as VKC approval. |
| Tacrolimus ointment on lids | Mostly dermatology-registered; eyelid use usually off-label. Not as eye drops; no dosing here. |
| Long-term steroids | Pressure, cataract and infection risks: see the steroid eye-drops page; steroid-sparing is arranged by a doctor. |
Go to A&E now (if you cannot travel, call 999)
- Sudden vision drop or sudden blindness
- Severe eye pain with headache and vomiting — rule out acute angle closure and similar
- Much worse pain after use, sudden vision drop, heavy purulent discharge, or suspected severe infection / endophthalmitis
Same-day ophthalmology assessment when possible
- New herpes-like blisters, severe photophobia or a white corneal spot — see an ophthalmologist as soon as possible
- Ongoing severe stinging after drops with clear vision worsening
- Suspected active infection while still on immunosuppressive drops/ointment — the doctor decides whether to stop
- Child / adolescent VKC or corneal involvement — do not treat as ordinary red eye and self-buy medicine
Main risks and cautions (education)
- Cyclosporine: stinging/burning common; usually stop in active infection
- Eyelid tacrolimus: early burning; off-label; label malignancy-risk concern (causality not fully established)
- Neither is OTC self-care; dose, course and suitability are only for the prescribing doctor — not stated here
- Does not erase all long-term steroid risk discussion — see the steroid eye-drops page
Common myths
| Myth | Closer to the evidence |
|---|---|
| “I can just switch my steroid to cyclosporine / tacrolimus myself” | Needs a doctor; adding immunosuppression during active infection can worsen disease. |
| “Cyclosporine eye drops are OTC and cure dry eye / allergy” | Prescription-only in Hong Kong; not OTC self-care and not a cure promise. Not a purchase pitch. |
| “An overseas same-strength VKC cyclosporine emulsion means severe VKC is approved in Hong Kong” | Overseas and Hong Kong labelled indications can differ; do not write a HK dry-eye use as VKC approval. |
| “Tacrolimus ointment can be used as eye drops” | No. Eyelid use is usually off-label; only a doctor decides. |
| “These medicines have no side effects” | Burning is common; infection and sudden vision-drop red flags mean stop and seek care. |
| “Under-twos can self-buy and use it” | Generally not used under age two; do not self-buy for the eyes. |
