There are not a lot of oral medications approved for the treatment of a yeast infection. The main problem is the cell membrane of fungus (yeast is a fungus) is very similar to the cell membranes of humans and other animals. So there is an obvious concern, and rightly so, that a medication will not cause harm to human cells while trying to kill the fungus (yeast) cells. So it's easy to understand why there are only approximately ten compounds that have been cleared for oral
treatment of yeast infections.
External yeast infections, of course, are a different matter and the oral drugs mentioned above are meant for use when an internal yeast infection is present.
One thing we all have a general idea about regarding infections is much depends on the exact cause and whether the organism has become resistant to common medicines. Vaginal yeast infections are very routinely, and successfully, treated by women using nonprescription creams or vaginal suppositories. Fluconazole is an anti-fungal from the triazole antifungals that can be taken orally and works quite well. It is available both over-the-counter and with a prescription. Sometimes a yeast infection will clear up after just one dose. Being able to cure your yeast infections by just taking one treatment is nice; however, it mainly only works on yeast infections. Fluconazole, under its various brand names, almost always requires a prescription from your doctor.
One class of serious drugs is the polyene anti-micotics. They bind to the ergosterol in the fungal cell membrane, which leads to the death of the cells. Two medications that are polyene antibiotics are Amphotericin B and Nystatin. It's true, Amphotericin B can be used to treat Oral Thrush, but it is also very effective when used intravenously to treat serious, life-threatening systemic fungal infections. Infections of this class can put your life in jeopardy. Treat them with the seriousness they deserve. Esophageal, vaginal, and mucosal Candidiasis can be treated effectively with Nystatin. While polyene antibiotics aren't of the azole class, they are both ergosterol inhibitors.
Whenever you are faced with a yeast infection that keeps returning, there are steps you can take to help prevent this from happening again, in addition to applying the proper treatment. Something that is very important to do when you have a child who has oral thrush is to constantly wash and sterilize anything that comes into contact with the child's mouth. To keep yourself free of a yeast infection if you are nursing an infant who has oral thrush, check your breast area and nipples each day. One preventative measure is to always wash the area with a diluted solution of live-culture yogurt. The best thing to do, as always, is simply visit your doctor and get their expert opinion on what you should do. If you see your doctor and get the correct treatment for your infection, you will be assured that the treatment will bring successful results and be safe. It's important to be concerned if you have a yeast infection when you are pregnant, as we talked about previously. But there are other yeast infection situations that should concern you also - such as a suspected yeast infection in a baby or child. Another good benefit of talking to your doctor about your infection is that you will be more familiar with the symptoms of a vaginal infection in the event it returns.
