Preparation Outbreak Prophylaxis

HF2C 1-4x/day 2-4x/week
HA1 As required* 1x/day
HB2/HB2A 1-3x/day† 2-3x/week
HB3A 1x/day† 2-3x/week
HB4A 1-2x/day† 1-3x/week
HB5 1-2x/day† 1-3x/week

* HA1 is supposed to relieve pain and similar viral symptoms within a couple of hours and can be reapplied if symptoms return.

† The HB series was designed primarily for longer-term suppression. HB2A may cause itching the first few times it is used. HB3A, HB4A and HB5 can cause flaking of the skin if applied too heavily or too often.

DOSAGE AMOUNT: The typical dosage is 10mg per square inch, 10mg/2.5cm². For comparison, a drop of water from a small pipette is about 33mg. Unless a large area is being covered, excess liquid needs to be wiped off the brush in the neck of the bottle. This is true for almost all the preparations. HA1 can be spread more liberally, followed by HF2C and HB2A. Irritation etc. on application often diminishes with use, so initial use should always be sparing.

The Preparations

Target preparations use a variety of ingredients, many of which have antiviral properties. Typically 25% of the preparation is antiviral. All except HA1 should be applied sparingly.

These formulations are supposed to be in increasing potency, i.e. effectiveness. Whether this is the case is what the trials are seeking to establish. Advanced chemistry techniques are used to achieve skin penetration.

One thing to note: Target preparations are antiviral, and are likely to impede healing of broken skin. Once a sore has started to heal, paint around the wound if necessary.

  • HF2, the original formulation, "Hopefully Final"(!)
  • HF2A, not issued, abandoned
  • HF2B, inferior permeation, few issued, abandoned
  • HF2C, simpler formulation sequence, should be the same or better than the first HF2
  • HB1, unstable formulation, abandoned
  • HB2, more stable version of HB1
  • HB2A, subtle refinement of HB2
  • HB3, skin dryness etc. reported by some participants
  • HB3A, slightly milder version of HB3 to reduce side-effects
  • HA1, according to a report several decades ago, this preparation will be safe and effective. Particularly suitable for intimate areas and children
  • HB4, development started November 2017. Similar to HB3 but includes a natural oil which is kinder to skin
  • HB4A, considerably milder version of HB4
  • HB5, introduced Jan. 2020, a combination of HB3A and HB4. The most complex formulation to date.
