There are no over the counter remedies that work. If the Aldara isn't working, then you should consider having them frozen off by your dermatologist.
Also some of us on here (who are not doctors) believe that a strong immune system can help the recovery. This means taking vitamins/supplements that boost immune systems, exercising, getting more rest, reducing stress, no cigs, no or much less alcohol, meditation, etc. Leading a very healthy life without stress will make you feel better and stronger. Obviously, no sex until they are gone for at least 3-6 months since sex will hamper recovery. For some reason, about 10% of the infected have trouble getting rid of genital warts. No one really knows why.
