I have sufficient information for a thorough, evidence-based answer.

Clinical Assessment: Almost Certainly Scabies

Looking at the image and the clinical details together - this is scabies until proven otherwise.

Why the diagnosis fits:

Generalized papular eruption with excoriated erythematous papules (visible in photo)
Nocturnal pruritus (hallmark - due to increased mite activity with warmth at night)
Started on hands (classic entry point - interdigital web spaces)
Sparing of face/scalp/neck is typical in adults (the "fingers and genitals spared" you mention is slightly atypical for genitals, but extensive secondary excoriation and post-inflammatory change can obscure the classic pattern)
Duration since April (2+ months) - explains widespread sensitization
Itraconazole failure - antifungals have zero effect on Sarcoptes scabiei

What to Do Now

Step 1 - Confirm the Diagnosis

Before treating, confirm with skin scraping from an intact burrow or papule (volar wrist, web spaces):

Microscopy for mites, eggs, or fecal pellets (scybala)
Dermoscopy is a quick office tool - look for the "delta-wing jet with contrail" sign (mite at end of burrow)

Step 2 - First-Line Treatment (Do BOTH)

Option A: Permethrin 5% cream (first-line per all guidelines)

Apply from jawline to toes, thin but thorough coat
Include web spaces, under fingernails, umbilicus, belt line
Leave on 8-12 hours (overnight), then wash off
Repeat in 7-14 days (not ovicidal on first application)

Option B: Oral Ivermectin 200 mcg/kg single dose

Since this is a prolonged, treatment-naive case (only itraconazole given - no actual scabicide), start with standard dosing
Give two doses 7-14 days apart (Cochrane evidence shows this reduces failure rates significantly vs. single dose; 2024 meta-analysis [PMID 37625798] confirms two-dose oral ivermectin failure rate of 7.1% vs. 15.2% for single dose)

Best approach for this case given 2+ months duration: Combine both - permethrin topically + oral ivermectin (synergistic, especially for established infestation with high burden)

Step 3 - Treat All Close Contacts Simultaneously

This is critical. Re-infestation from household members is the most common cause of "treatment failure." Everyone in the household and intimate contacts must be treated on the same day, regardless of symptoms.

Step 4 - Environmental Decontamination

Wash all clothing, bed linen, towels used in the past 3 days in hot water (60°C) and dry on high heat
Items that cannot be washed: seal in plastic bags for 72 hours (mites die within ~24-72 hours off a host)

Step 5 - Manage Post-Scabetic Itch

Pruritus can persist 4-6 weeks after successful treatment (due to remaining dead mite antigens). This is NOT treatment failure. Manage with:

Oral antihistamine (cetirizine or hydroxyzine at night)
Mild topical steroid (hydrocortisone 1%) for eczematous areas
Emollients

Red Flags to Watch For

Feature	Concern
Thick crusted/hyperkeratotic plaques	Crusted (Norwegian) scabies - needs 3-7 doses ivermectin + keratolytics
No response after proper treatment + contact treatment	Check immunosuppression (HIV, diabetes)
Secondary bacterial infection	Add antibiotic (cephalexin) if pustules/honey crusting

Summary

Drug	Dose	Schedule
Permethrin 5% cream	Apply head-to-toe (below jawline)	Day 1 and Day 8
Ivermectin oral	200 mcg/kg (~12 mg for 60 kg)	Day 1 and Day 8-14
Cetirizine 10 mg	Nightly	Until itch resolves

Do not repeat itraconazole - it has no role here.

I gave permethrin lotion plus bandy plus tab 2 tomorrow morning and ebast dc plus atarax anti itch lotion

Good treatment plan overall. Let me quickly review what you've prescribed:

What you gave:

Permethrin lotion ✅ - correct first-line scabicide
Bandy (albendazole) - this is an anthelmintic, not active against scabies mites
Tab 2 tomorrow morning - likely ivermectin 12mg (2 tabs of 6mg) ✅ - correct if this is ivermectin
Ebastine (Ebast) ✅ - non-sedating antihistamine, good for daytime
Atarax (hydroxyzine) ✅ - sedating antihistamine, excellent for night-time itch
Anti-itch lotion ✅ - symptomatic relief

Concerns / Suggestions

1. Bandy (Albendazole) - Unnecessary Here

Albendazole has no efficacy against Sarcoptes scabiei. Unless you suspect a co-existing helminthic infection (e.g., soil-transmitted helminths based on history/eosinophilia), this adds no benefit and just adds pill burden. You can skip it unless there's another indication.

2. Ivermectin - Confirm Two-Dose Schedule

If "Tab 2 tomorrow morning" = ivermectin 12mg (200 mcg/kg for ~60kg patient), that is the correct dose. But give it on an empty stomach for better absorption.

Repeat the same ivermectin dose on Day 8-14 - this is essential. Single dose alone has ~15% failure rate; two doses drops it to ~7% (Br J Dermatol 2024).

3. Permethrin - Application Technique is Critical

Make sure the patient understands:

Apply below the jawline, entire body including web spaces, under nails, umbilicus, groin folds
Leave on 8-12 hours (overnight), wash off in the morning
Repeat on Day 7

4. Treat All Household Contacts Today

If this is not done, re-infestation will make the treatment appear to fail within weeks.

Revised Practical Plan

Item	Action
Permethrin 5%	Night 1 and Night 8
Ivermectin 12mg	Morning Day 1 (empty stomach) and Day 8-14
Ebastine 20mg	Once daily (daytime)
Hydroxyzine 25mg	At night for itch/sleep
Bandy	Stop unless separate indication
Follow-up	2-3 weeks - warn patient itch may persist 4-6 weeks even after cure

Overall a solid approach - the main thing to add is the repeat ivermectin dose in 1-2 weeks and ensure simultaneous household contact treatment.

Can we see results in 5 days

Results Timeline for Scabies Treatment

In 5 days - partial improvement only, not full clearance.

Here is what to realistically expect:

Day 1-3

Itch may temporarily worsen initially - this is normal (dying mites + ongoing immune reaction)
No visible change in rash yet
Patient may think treatment is not working - reassure them

Day 3-5

Nocturnal itch begins to reduce noticeably - this is the first positive sign
New lesions stop appearing
Existing papules still visible (will take longer to fade)

Day 7-10

Significant itch reduction expected
This is also when you give the second dose of permethrin + repeat ivermectin
Rash starts fading but post-inflammatory marks persist

Week 2-4

Skin progressively clears
Some patients have persistent itch for 4-6 weeks even after complete mite kill - this is post-scabetic hypersensitivity, NOT treatment failure

Key Message to Tell Your Patient

"The medicine is killing the mites, but your skin takes time to heal. Itch improving by Day 4-5 means it is working. Do not stop treatment. Come back in 2 weeks for review."

When to Suspect True Treatment Failure (after 4 weeks)

New burrows appearing
Itch completely unchanged or worsening beyond week 2
Household contacts not treated (most common reason)
Check for crusted scabies if very high mite burden

Bottom line - tell the patient to judge response at 2 weeks, not 5 days.

Blood test needed for this

Blood Tests for Scabies

For routine, uncomplicated scabies in a healthy 28-year-old - no blood tests are mandatory. Scabies is a clinical diagnosis.

However, in this case (2+ months duration, widespread involvement, on itraconazole suggesting prior misdiagnosis), some targeted tests are worthwhile:

Useful in This Case

Test	Why
CBC with differential	Look for eosinophilia - supports parasitic infestation; also rules out secondary infection
Blood sugar (RBS/FBS)	Uncontrolled diabetes impairs treatment response and increases susceptibility
HIV screening	Young male, prolonged/severe scabies - HIV can cause atypical/crusted scabies; important to rule out

Not Routinely Needed

Test	Reason to Skip
LFT/KFT	Not needed unless giving multiple doses of ivermectin in a compromised patient
IgE / allergy panel	Not useful - eosinophilia on CBC is sufficient
Serology for scabies	No validated commercial test exists

Most Important "Test" in This Case

Skin scraping with microscopy - still the most clinically useful investigation:

Scrape a fresh papule or burrow from the wrist/web space
Look under microscope for mite, eggs, or fecal pellets
Takes 5 minutes, costs almost nothing
Confirms diagnosis and justifies treatment to the patient

Practical Recommendation

Order:

CBC with differential - check eosinophils
Fasting blood sugar
HIV test (with counselling)

These three cover the important bases without unnecessary expense. If all normal, treat confidently and review at 2 weeks.

Ok u sure it's scabie no..becoz fingers r spared

Fingers Spared - Does it Rule Out Scabies?

Short answer: No, it does not rule out scabies. But it does make the diagnosis less typical, and you are right to question it.

Why Fingers May Be Spared

Several reasons this can happen in genuine scabies:

Chronic/longstanding infestation - by 2+ months, the patient has been scratching heavily. The web spaces and finger lesions may have been scratched flat, crusted over, or secondarily infected and are now unrecognizable as classic burrows. The primary lesions have been replaced by excoriations.
Heavy scratching behaviour - constant mechanical abrasion on fingers may prevent mite establishment there while the rest of the body is colonized.
Prior partial treatment - if the patient used any topical cream on hands before (even moisturizer or OTC antifungal), finger burden may have reduced while trunk involvement persisted.
Atypical distribution - textbooks say interdigital spaces are the classic site, but widespread truncal involvement with relative sparing of hands is well documented, especially in adults with good hand hygiene.

What Still Strongly Favors Scabies

Nocturnal itch - very specific
Started on hands (even if now cleared there)
2+ months duration with spread
Age, no systemic illness
Itraconazole failure (rules out tinea)
Image: scattered erythematous papules on trunk - classic post-excoriation scabietic picture

Differential Diagnoses to Keep in Mind

If scabies treatment fails at 4 weeks, consider:

Diagnosis	Distinguishing Feature
Papular urticaria	Insect bite history, seasonal, lesions in clusters
Prurigo nodularis	Firm nodules, chronic, excoriated tops
Dermatitis herpetiformis	Vesicles, gluten-sensitive enteropathy, IgA on biopsy
Atopic dermatitis	Personal/family atopy history, flexural distribution
Bullous pemphigoid (early)	Older age usually, urticarial phase before blisters
Drug reaction	Recent drug history

My Honest Assessment

The finger-sparing is an atypical feature, not a disqualifying one. The overall clinical picture still favors scabies as the most likely diagnosis.

The treatment you have given (permethrin + ivermectin) is both the right treatment for scabies AND a reasonable empirical trial. If there is no response at 2-3 weeks after proper treatment including contacts, then revisit the diagnosis and consider:

Skin scraping (if not done)
Skin biopsy
