I take these natural water pills at certain times when I am retaining water and feeling discomfort from that. You need to take these with a full glass of water. Also, you should be drinking a lot of water throughout the day and to try to really limit your salt intake. I usually take one of these pillls an hour or two before bed with a big glass of water. They do not have an immediate impact on how I am feeling, so they are not a quick fix; however, I end up feeling much better the next morning. If you have a real problem, you may need an over the counter water pill or even a water pilll prescribed by your doctor, but before you try those more "serious" fixes, I recommend you consider taking these natural pills. I personally always prefer an herbal approach --- if it works! Each pill is quite large and if you have a problem swallowing pills, these pills may be a problem for you. There is no coating and they are chalky. I think they are a good option for occasional use.
