What is Zidoval Gel?
Zidoval Gel is an antibiotic gel (active ingredient metronidazole) used to treat bacterial vaginosis, a common condition that affects millions of women. The gel is inserted into the vagina using disposable plastic applicators that come with the medication. This is a quick and painless procedure that you can carry out on your own. Zidoval Gel targets anaerobic bacteria in your vagina that are responsible for causing bacterial vaginosis. Your online GP will give you precise individual instructions for using the medication, but the usual treatment is a daily application of gel for 5 days. This is generally enough to restore the natural bacterial and pH balance in your vagina and cure bacterial vaginosis.
What is the active ingredient of Zidoval Gel?
The active ingredient of Zidoval Gel is an antibiotic called metronidazole present at 0.75% concentration. It has many therapeutic uses and is widely used for the treatment of bacterial vaginosis, either as tablets, creams or gel. A five day course of metronidazole (applied as Zidoval Gel) is usually enough to cure a typical outbreak of BV.
How does Zidoval Gel work?
A healthy vagina is a slightly acidic environment that contains a mixture of natural bacteria. These are lactobacilli or ‘good bacteria’ and anaerobic bacteria or ‘bad bacteria’. If there is a sudden growth of bad bacteria, it can cause bacterial vaginosis (BV). Regular applications of antibiotic Zidoval Gel allow the active ingredient metronidazole to target the bad bacteria. This restores the natural bacterial balance inside your vagina and cures your bacterial vaginosis. It is important to use Zidoval Gel exactly as instructed by your online GP, even if you appear to be free of any symptoms of BV. If you do not, the infection can quickly return and may be harder to overcome.
Who can take Zidoval Gel?
Our online GPs will usually consider prescribing Zidoval Gel to adult women suffering from bacterial vaginosis. In order to receive a prescription, you must satisfy the basic health requirements to use Zidoval Gel. If you are allergic to the active ingredient metronidazole or to any similar nitroimidazole antibacterials, or to parabens (a preservative agent) you cannot use the gel.
If you are in the first three months of pregnancy or are breastfeeding, you should advise our online GP. When you complete the short online medical questionnaire, our duty GP will immediately check whether Zidoval Gel is safe for you to take. If we cannot issue a prescription for Zidoval Gel, you may be offered a different treatment for bacterial vaginosis like Dalacin Cream or Metronidazole.
What doses of Zidoval Gel are available?
Zidoval Gel contains a 0.75mg concentration of the antibiotic metronidazole. A 5 gram dosage of the gel is self-administered into the vagina using one of the disposable applicators that are provided with the gel. This is a quick and painless procedure, and the gel itself should cause no discomfort when it is inside your body. Your online GP will give you precise individual instructions about how and when to apply the gel. A typical course of treatment for bacterial vaginosis involves applying a single dose every night before going to bed. This is repeated for five consecutive nights.
You may find that your symptoms rapidly ease, or even disappear altogether after you start treatment. You should still continue to apply the gel exactly as instructed by our GP. If you cease the treatment prematurely, your bacterial vaginosis may rapidly return and could be harder to treat.
How to use Zidoval Gel?
Your online GP will tell you exactly how to use Zidoval Gel and for how many days to continue the treatment. A typical course of treatment usually lasts five days. Zidoval Gel is a self-administered medication that is designed to be directly inserted into the vagina. A set of disposable applicators is provided with the gel, and the process is similar to inserting a tampon or contraceptive ring.
