Time-sensitive early intervention strategy for use after known or suspected exposure
Time-sensitive protocol designed for immediate action within 24-48 hours of known or suspected exposure.
Higher initial dose provides rapid therapeutic levels to address potential infection before symptoms develop.
Only 2 doses required, 48 hours apart, making it a convenient and focused intervention strategy.
Ideal for specific exposure events rather than ongoing prevention, with clear start and end points.
This protocol is appropriate for specific exposure scenarios. Evaluate your situation to determine if post-exposure prophylaxis is warranted.
Extended close contact (within 6 feet for 15+ minutes) with a confirmed infected individual.
Living with or caring for someone who has tested positive or is showing symptoms.
Healthcare workers with patient exposure despite PPE, or known PPE breach during patient care.
Extended travel (flight, train, bus) with confirmed case notification or high-risk environment.
Notification of confirmed case in shared workspace with direct interaction or shared air space.
Attendance at gathering or event with subsequent confirmed case notification.
Follow this timeline for optimal implementation of the post-exposure protocol
Evaluate exposure risk level and determine if post-exposure protocol is appropriate.
Take first dose as soon as possible after exposure confirmation, ideally within 24-48 hours.
Take second dose exactly 48 hours after the first dose to complete the protocol.
Continue monitoring for symptom development during the typical incubation period.
Reference chart for 0.4 mg/kg post-exposure dosing. Each dose in the 2-dose protocol uses this amount.
| Body Weight | Dose per Administration | 3mg Tablets | 6mg Tablets | 12mg Tablets |
|---|---|---|---|---|
| 110 lbs (50 kg) | 20 mg | 7 tablets | 3-4 tablets | 2 tablets |
| 132 lbs (60 kg) | 24 mg | 8 tablets | 4 tablets | 2 tablets |
| 154 lbs (70 kg) | 28 mg | 9-10 tablets | 5 tablets | 2-3 tablets |
| 176 lbs (80 kg) | 32 mg | 11 tablets | 5-6 tablets | 3 tablets |
| 198 lbs (90 kg) | 36 mg | 12 tablets | 6 tablets | 3 tablets |
| 220 lbs (100 kg) | 40 mg | 13-14 tablets | 7 tablets | 3-4 tablets |
Total Protocol Supply Needed:
The post-exposure protocol requires 2 doses. Multiply the single dose amount by 2 to determine total tablets needed. For example, a 154 lb person needs approximately 56 mg total (28 mg × 2 doses).
Understanding when to use post-exposure versus other protocols
| Aspect | Post-Exposure | Preventive | Active Treatment |
|---|---|---|---|
| Timing | Within 24-72 hours of known exposure | Ongoing, regardless of exposure | After symptom onset |
| Dose | 0.4 mg/kg (higher) | 0.2 mg/kg (lower) | 0.4-0.6 mg/kg (highest) |
| Duration | 2 doses only | Weekly/bi-weekly ongoing | 5 days daily |
| Purpose | Prevent infection after exposure | Reduce risk before exposure | Treat active infection |
Multiple clinical trials have examined ivermectin for post-exposure prophylaxis, showing potential benefits when administered within 72 hours of exposure.
The 48-hour dosing interval is based on ivermectin's half-life and tissue distribution, maintaining therapeutic levels during the critical early exposure period.
The 2-dose post-exposure protocol uses well-established dosing within the safety parameters documented in decades of clinical use.
The post-exposure protocol is most effective when started within 24-48 hours of known exposure. Effectiveness may decrease if started more than 72 hours after exposure. The sooner you begin, the better the potential outcome.
If you're already taking weekly preventive doses and experience a known exposure, you can switch to the post-exposure protocol. Take the higher dose (0.4 mg/kg) immediately, then the second dose 48 hours later. Resume your preventive schedule one week after completing the post-exposure protocol.
Follow current public health guidelines for quarantine after exposure. The post-exposure protocol does not replace quarantine recommendations. Monitor for symptoms and limit contact with vulnerable individuals during the monitoring period.
If symptoms develop during or after the post-exposure protocol, transition to the active treatment protocol (0.4-0.6 mg/kg daily for 5 days). Consult with a healthcare provider for guidance on managing your specific situation.
Yes, the post-exposure protocol can be used for discrete exposure events. However, if you experience frequent exposures, consider transitioning to a preventive protocol for ongoing protection rather than repeated post-exposure dosing.
Yes, the 48-hour interval is based on pharmacokinetic data showing optimal drug levels with this timing. Taking doses too close together or too far apart may reduce effectiveness. Aim for exactly 48 hours, though a window of 46-50 hours is acceptable.
Don't wait until exposure happens. Have pharmaceutical-grade Ivermectin on hand for rapid response when you need it most.
