| Drug | Renal Adjustment (eGFR cutoff) | Liver Adjustment | Pregnancy (FDA / PLLR) | Critical Toxicity / Key Monitoring |
|---|---|---|---|---|
| Topical Tretinoin | No dosage adjustment required | No dosage adjustment required | Contraindicated as a precaution | Retinoid dermatitis, local peeling. |
| Oral Isotretinoin | Does not require mild; caution | Contraindicated in severe failure | Category X (Absolute contraindication) | Teratogenicity (iPLEDGE), cheilitis, hypertriglyceridemia. Control transaminases and lipids. |
| Clobetasol Propionate | No adjustment required; avoid large areas | Not required; caution in prolonged use | Compatible with caution (low dose) | Skin atrophy, purplish striae, tachyphylaxis. Staggered withdrawal to avoid rebound. |
| Topical Tacrolimus | No dosage adjustment required | No dosage adjustment required | Not recommended (Prefer mild steroids) | Transient local burning or burning sensation, alcohol intolerance. Does not produce atrophy. |
| Methotrexate | Reduce 50% in eGFR 30-59; contraindicated < 30 | Contraindicated in Child B/C cirrhosis | Category X (Absolute contraindication) | Acute myelosuppression, pneumonitis, liver cirrhosis. Supplement with Folic Acid weekly. |
| Cyclosporine | Contraindicated if basal creatinine increases > 30% | Reduce dose in Child C due to CYP3A4 | Strict monitoring supported | Afferent arteriole nephrotoxicity, hypertension, gingival hyperplasia. Limit to 1 year of continuous use. |
| Adalimumab | No dosage adjustment required | No dosage adjustment required | Compatible; suspend week 30-32 | Reactivation of Latent Tuberculosis, paradoxical psoriasis. Mandatory screening with PPD/IGRA. |
| Secukinumab | No dosage adjustment required | No dosage adjustment required | Not recommended as a precaution | Fungal infections due to Candida. Care in active Inflammatory Bowel Disease. |
| Risankizumab | No dosage adjustment required | No dosage adjustment required | Not recommended as a precaution | Headache, nasopharyngitis. Excellent dosage convenience (every 12 weeks). |
| Dupilumab | Does not require topical/systemic treatment | No dosage adjustment required | Compatible with precautions | Non-infectious conjunctivitis, keratitis. Treat with artificial tears or mild ophthalmic corticosteroids. |
| Baricitinib | Reduce 50% in eGFR 30-60; contraindicated < 30 | Contraindicated in severe liver failure | Absolutely contraindicated | Major cardiovascular events (MACE), venous thromboembolism (VTE), reactivation of Herpes Zoster. |
| Terbinafine Oral | Avoid if eGFR < 50 mL/min due to lack of data | Contraindicated in active hepatitis or cirrhosis | Not recommended (Avoid systemic) | Fulminant idiosyncratic hepatotoxicity, transient ageusia. Check transaminases at weeks 4-6. |
| Doxycycline | No adjustment required (mixed elimination) | Use with caution in Child C | Contraindicated in T2 and T3 (dental staining) | Pill ulcerative esophagitis, phototoxic photosensitivity. Avoid eating dairy products and going to bed. |
| Oral Ivermectin | No dosage adjustment required | Caution in Child C (biliary clearance) | Avoid in the first trimester | Neurotoxicity if it penetrates the blood-brain barrier (P-glycoprotein). Repeat takes 7-14 days. |
| Vismodegib | Not required in mild-moderate | Not established; monitor | Category X (Absolute contraindication) | Extreme teratogenicity (midline development), muscle spasms, ageusia, alopecia. Mandatory contraception for 24 months. |
| Lidocaine with Epinephrine | No single dose adjustment required | Caution if massive injection in Child C | Compatible (Local anesthetic of choice) | LAST syndrome (neuro and cardiotoxicity) due to accidental intravascular injection. Avoid epinephrine in acra. |
