🩺 Treatment Guidelines & Management of Common Skin Conditions
| Skin Condition |
First-Line Treatment |
Long-Term Management |
Special Considerations |
| Acne Vulgaris |
Topical retinoids (e.g., adapalene), benzoyl peroxide, clindamycin |
Oral antibiotics (doxycycline), hormonal therapy (in females), isotretinoin (severe) |
Avoid during pregnancy: oral retinoids; mild topicals like azelaic acid preferred |
| Eczema (Atopic Dermatitis) |
Emollients, topical corticosteroids (low to mid potency) |
Avoid allergens, wet-wrap therapy, antihistamines for itch |
Safe in pregnancy: moisturizers, low-potency steroids; avoid systemic immunosuppressants |
| Psoriasis |
Topical corticosteroids, vitamin D analogs (calcipotriol) |
UVB phototherapy, methotrexate, biologics (e.g., TNF inhibitors) |
May flare in pregnancy; use emollients and UVB; avoid methotrexate & retinoids |
| Rosacea |
Metronidazole or azelaic acid topically, doxycycline orally |
Laser therapy for telangiectasia, lifestyle changes (avoid triggers) |
Azelaic acid and low-dose doxycycline are pregnancy-safe; avoid topical steroids |
| Contact Dermatitis |
Remove irritant/allergen, topical corticosteroids |
Patch testing to identify allergen, skin barrier repair |
Use mild steroids in pregnancy; occupational exposure often requires PPE |
| Fungal Infections (Tinea) |
Topical antifungals: clotrimazole, terbinafine |
Oral antifungals (griseofulvin, fluconazole) if widespread |
Topical azoles are pregnancy-safe; avoid oral antifungals in first trimester |
| Vitiligo |
Topical corticosteroids, calcineurin inhibitors |
Phototherapy (NB-UVB), camouflage therapy |
Cosmetic distress common; safe options in pregnancy include tacrolimus topically |
| Seborrheic Dermatitis |
Antifungal shampoos (ketoconazole), low-potency topical corticosteroids |
Selenium sulfide, zinc pyrithione, maintenance antifungal use |
Recurrence common; safe in pregnancy with topical antifungals and emollients |
| Urticaria (Hives) |
Oral antihistamines (cetirizine, loratadine) |
Identify and avoid triggers, immunomodulators in chronic cases |
Pregnancy-safe antihistamines: loratadine, cetirizine; avoid systemic steroids unless needed |
| Skin Cancer (Non-Melanoma) |
Surgical excision, Mohs surgery (for high-risk BCC/SCC) |
Regular dermatologic follow-up, sun protection, topical chemotherapy (5-FU) for early lesions |
Pregnancy-safe procedures include excision; radiation and some topical agents are avoided |
Key Notes:
- Topical corticosteroids are used in many skin conditions; potency must be adjusted based on the area (face vs. body).
- Phototherapy (NB-UVB) is safe and effective for psoriasis, eczema, and vitiligo.
- Systemic agents (e.g., methotrexate, isotretinoin, immunosuppressants) require monitoring and are contraindicated in pregnancy.
- Pregnancy-safe treatments include azelaic acid, clindamycin (topical), emollients, and UVB phototherapy.
