Here is a thorough answer based on authoritative medical textbooks:
Treatment of Drug-Induced Hypersensitivity
Step 1 - Most Important: STOP the Offending Drug
The first and most critical step in ALL forms of drug-induced hypersensitivity is to immediately identify and discontinue the causative agent.
Treatment by Severity and Type
1. Mild Reactions (Rash, Urticaria, Pruritus)
| Drug | Role |
|---|---|
| Antihistamines (cetirizine, loratadine, diphenhydramine) | Relieve itching and urticaria |
| Topical corticosteroids | Reduce local inflammation |
"The most important step in the treatment of drug-induced urticaria is withdrawal of the causative agent." - Dermatology 2-Volume Set 5e
2. Moderate Reactions (Widespread rash, angioedema)
| Drug | Dose/Route |
|---|---|
| Systemic corticosteroids (prednisolone/prednisone) | Oral, 0.5 mg/kg/day |
| Antihistamines (H1 blockers) | Oral or IV |
| H2 blockers (ranitidine/famotidine) | Can be added alongside H1 blockers |
3. Anaphylaxis (Most Severe - Life-threatening)
| Priority | Drug | Route |
|---|---|---|
| 1st line | Epinephrine (Adrenaline) 0.3-0.5 mg | IM (thigh) - IMMEDIATE |
| 2nd | IV fluids (normal saline) | IV bolus |
| 3rd | Corticosteroids (hydrocortisone 200 mg or methylprednisolone) | IV |
| 4th | Antihistamines (diphenhydramine/chlorpheniramine) | IV |
| 5th | Salbutamol/bronchodilators | Nebulised (if bronchospasm) |
4. DRESS / Drug-Induced Hypersensitivity Syndrome (DIHS)
DRESS = Drug Reaction with Eosinophilia and Systemic Symptoms. This is a severe, delayed reaction (onset 2-8 weeks after starting drug).
Causative drugs most commonly: anticonvulsants (phenytoin, carbamazepine, phenobarbital, lamotrigine), sulfonamides, allopurinol, nevirapine, abacavir, dapsone, minocycline.
| Drug | Details |
|---|---|
| High-dose systemic corticosteroids | 1-2 mg/kg/day - FIRST LINE; often with slow taper over weeks to months |
| IV immunoglobulin (IVIG) | Used in severe/refractory cases |
| Cyclosporine | Used in severe or steroid-resistant DRESS |
| Pulse IV methylprednisolone | For very severe cases |
"First-line treatment for DRESS involves identifying and stopping the causative agent, and initiation of anti-inflammatory therapy, generally with high dose systemic corticosteroids (1-2 mg/kg/day). Pulse intravenous steroids, IVIG, cyclosporine, and other agents have been employed in severe or recalcitrant cases." - Andrews' Diseases of the Skin
5. Stevens-Johnson Syndrome (SJS) / Toxic Epidermal Necrolysis (TEN)
These are the most severe drug hypersensitivity reactions affecting the skin and mucous membranes.
| Drug | Role |
|---|---|
| Supportive care (burns unit approach) | Fluid/electrolyte management |
| Cyclosporine | Emerging evidence as preferred immunosuppressive |
| IVIG | Widely used, especially in TEN |
| Corticosteroids | Controversial; used in some centers |
| Antibiotics | For secondary infection |
Quick Summary Table
| Reaction Type | Key Drug(s) |
|---|---|
| Mild rash/urticaria | Antihistamines + stop drug |
| Moderate reaction | Oral corticosteroids + antihistamines |
| Anaphylaxis | Epinephrine (1st line!) + fluids + steroids |
| DRESS/DIHS | High-dose corticosteroids (1-2 mg/kg/day) ± IVIG/cyclosporine |
| SJS/TEN | IVIG/cyclosporine + supportive care |
Key point to remember for exams: In anaphylaxis, epinephrine is always the first-line drug - not antihistamines, not steroids. Antihistamines and corticosteroids are important but are secondary measures.

follicular study USG day 2 menstrual cycle when to advise patient infertility
Based on the image analysis and medical knowledge, here is the complete answer:
This is a Follicular Study (USG)
The image contains handwritten notes in Hindi/English that read:
- "दूसरे दिन" / "D2" = Day 2 of menstrual cycle
- "Pelvi/954" = Pelvic USG
- "Follicular Study" with a drawing/diagram
- "अंडाण / अंड दान" = Egg / Ovum (referring to follicle/egg)
What is Follicular Study USG?
A Follicular Study (also called Ovulation Study or Ovulation Monitoring) is a series of transvaginal or transabdominal ultrasound scans done to track the growth of ovarian follicles and predict the exact day of ovulation.
A mature follicle ready for ovulation measures 18-25 mm.
When Do We Tell the Patient to Start?
| Day | What is Done |
|---|---|
| Day 2 or Day 3 (of menstrual cycle) | Baseline scan - assess antral follicle count, ovarian reserve, and uterine lining (this is what "D2" in your notes refers to) |
| Day 6-9 | Follow-up scan - monitor initial follicle growth |
| Day 9-14 | Repeat scans every 2-3 days - main monitoring phase |
| Day 12-16 | Most likely ovulation window - scans may be done daily |
| Ovulation confirmed | Follicle disappears / collapses (post-ovulatory cyst seen) |
So the patient is first called on Day 2 or Day 3 of her period for the baseline pelvic USG, and then recalled at intervals until ovulation is detected.
When is Follicular Study Advised?
Tell your patient to get a follicular study in these conditions:
- Infertility - primary or secondary - most common indication
- Irregular menstrual cycles / anovulation - to check if ovulation is occurring
- PCOS (Polycystic Ovarian Syndrome) - to confirm ovulation
- IUI (Intrauterine Insemination) - to time the procedure correctly
- IVF (In-Vitro Fertilization) - to monitor ovarian stimulation
- Ovulation induction - when patient is on clomiphene or gonadotropins, to monitor follicle response
- Unexplained infertility - to evaluate ovulatory dysfunction
- Recurrent pregnancy loss - to assess ovulatory function
Simple Instructions to Give Patient (in OPD)
"Come for your first scan on Day 2 or Day 3 of your next period (Day 1 = first day of bleeding). Keep your bladder moderately full. We will call you again around Day 10-12 and repeat scans every 2-3 days until we confirm ovulation."

Here is exactly what is written in the image, decoded carefully:
What is Written in the Image
| Location | Text | Meaning |
|---|---|---|
| Top Right | Ro ① / पाँच दे | Probably "Give 5" (dose instruction) |
| Middle Left (underlined heading) | दूसरे दिन | "Second Day" = Day 2 of menstrual cycle |
| Below heading | Relu1954 or Pelvi954 | Likely "Pelvis USG" (Pelvic Ultrasound) |
| Below | t p 10 | Possibly "tape / time point 10" |
| Below | cyst with a circle symbol ∅ | Ovarian Cyst - what to look for |
| Right side | D2 | Day 2 of cycle |
| Bottom right (in bracket) | भापन / मत पाए | Roughly = "do not find / should not be seen" - meaning the cyst should NOT be present |
So This USG is:
Pelvic USG on Day 2 of Menstrual Cycle
Purpose: Baseline Ovarian Cyst Check
The note says:
"On Day 2 - do Pelvic USG - check for cyst - it should NOT be present"
Why is this Done?
This is a baseline pelvic USG (Day 2 scan) done before starting ovulation induction (e.g., with Clomiphene/Letrozole/Gonadotropins).
Reason: Before starting ovarian stimulation drugs, you MUST confirm there is NO residual ovarian cyst from the previous cycle.
| Finding | Action |
|---|---|
| No cyst seen | Safe to start ovulation induction drugs |
| Cyst present (>15mm) | Delay treatment, do NOT start drugs - wait for cyst to resolve |
When to Tell the Patient:
"Come for a pelvic ultrasound on Day 2 or Day 3 of your next period (Day 1 = first day of full bleeding) - before starting your fertility medicines."
This is a routine step before IUI, IVF, or oral ovulation induction cycles to ensure the ovaries are in a resting "baseline" state and no leftover cysts are present.
