How to use vagisil
Use the smallest amount needed.
Using too much vagisil can lead to severe side effects, so only apply a small amount. The amount of vagisil cream that you use should be about as long as your fingertip (about one inch long).

Options are: I. However, be aware that it's sometimes recommended to use less more when you have conditions such as parkinson's disease; there's no scientific evidence to support this effect. When using vagisil, take a smaller dose than the dosage prescribed by your doctor. II. Using an extra small amount does not mean your finger is dead. It simply means you're using the right kind of tool. III. Use less if you experience side effects like nausea or diarrhea, or if you are pregnant. If your vagisil cream does not contain any iron or other nutrients, you should use less. IV. Apply vagisil to the outside of your vagina only. Do not insert vagisil into your vagina.
