Sorry Liz, I didn't see you question about using Multi Gyn Actigel. I tend to use it every evening after my shower (if you are prone to thrush you should not have baths, only have showers. Also avoid scented products and wear cotton undies).
I just put a big blob on the end of my finger and push it up inside and around the outside. I have found it keeps things healthier and prevents that nasty itching and soreness.
If i do get a proper bout of thrush (that horrible white cottage cheese type discharge) I then use the tube thing to squirt a bigger amount right up inside and do this morning and evening for two or three days.
Though this treatment is meant to be for Bacterial vaginitis, I find it treats thrush really well.
There are other gels like Hylaofemme and also some pessaries that are quite good as well. Basically all these preparations are designed to keep the vaginal area more acidic which means bacteria and thrush cannot take hold. I good dollop of this stuff after sex is a very good idea.
I believe it is a matter of managing the problem to prevent infection in the first place.
