Ok, we need time to wake up and check the forum from this side of the world! <img src="/images/graemlins/grin.gif" alt="" />

For tense blisters - you may pierce a few holes in the blister with a sterilised / sterile needle to drain the fluid. Never deroof the blister i.e. leave the skin on!!

Apply whatever tape over the blister - Micropore, bandaid, moleskin, ducttape etc - make sure the surrounding normal skin is included in the taped area. The idea here is to compress the loose skin down and the surrounding normal skin will provide support for the tape.
The tape is to provide cushioning and prevent further trauma to the area and to prevent the blister from reforming.
The type of tape used will depend on what you have on hand and whether you want the treated area to be aesthetically pleasing to the eye. Duct tape will do, but moleskin looks and feels nicer.....

There is no point in apply tape to the blister only without incluing some surrounding normal skin. The roof of the blister will be mobile and more likely to tear and lead to more trauma and an open wound.

Finally, DON'T rip off the tape as soon as you get home. When to take off the tape depends the type of tape used and how long its been on the skin. Leave for at least 24 h before attempting to remove. For some types of duct tape - good luck, micropore tape - easiest to remove, moleskin - remove with care...
Of course don't deroof the blister while you are attempting to remove the tape.....

If in doubt, seek your local MD!
