Product Information:

ZAFON FAST 8mg Tablets contain Dexamethasone 8mg, a potent synthetic glucocorticoid with strong anti-inflammatory, immunosuppressive, and anti-allergic properties. The "FAST" formulation typically indicates a rapidly disintegrating or immediate-release tablet, designed for quick onset of action in acute conditions.

Dexamethasone is approximately 25–30 times more potent than hydrocortisone and has minimal mineralocorticoid (salt-retaining) activity.

Uses of (ZAFON FAST 8MG):

1. Acute allergic reactions (e.g., severe urticaria, angioedema)
2. Cerebral edema (e.g., due to brain tumors or metastases)
3. Severe asthma exacerbations or COPD flare-ups (adjunctive therapy)
4. Nausea and vomiting in chemotherapy-induced emesis (as part of antiemetic regimen)
5. Adrenal insufficiency (stress-dose coverage during illness/surgery)
6. Inflammatory conditions: Rheumatoid arthritis, lupus, vasculitis
7. Prenatal use: To accelerate fetal lung maturity in preterm labor (off-label in some settings)

Key Benefits of (ZAFON FAST 8MG):

1. Rapid onset of anti-inflammatory action
2. Long half-life (~36–72 hours)—allows once-daily or pulse dosing
3. High glucocorticoid potency with negligible sodium retention
4. Oral convenience for outpatient or emergency use

How To Use (ZAFON FAST 8MG):

1. Take with food or milk to reduce gastric irritation.
2. Swallow whole with water—do not crush unless it's an orally disintegrating tablet (ODT).
3. Dosage and duration vary widely by condition:
4. Allergic/asthma flare: 4–8mg once daily for 3–5 days (tapered or short-course)
5. Cerebral edema: 10mg IV/IM initially, then 4mg every 6 hours; oral switch when stable
6. Chemotherapy support: 8–12mg once daily on treatment days
7. Never stop abruptly after >1 week of use—taper gradually to avoid adrenal crisis.

When Not to Use (ZAFON FAST 8MG):

Do not use if you have:
