Nizoral is a medicated shampoo that contains 2 % of an active ingredient known as ketoconazole. Ketoconazole is a synthetic antifungal substance. Normally, people use this medicated shampoo to treat yeast and fungal infections such as seborrheic dermatitis, seborrheic dandruff, and pityriasis versicolor.
Nizoral shampoo is effective in treating such infections because of ketoconazole, which is an active ingredient that destroys the membrane that constitutes part of the fungus and the yeast. After the destruction of the membrane, the inner parts of the yeast and the fungus start leaking halting their growth process immediately. Eventually, the organism dies.
As with any medicated product, there is a chance that people will experience side effects because of using it. The side effects may range from mild and moderate to severe side effects that can cause serious harm to an individual. It is important to note that severe side effects resulting from the use of this shampoo are rare. However, moderate changes to hair texture, allergic reactions, and skin reactions to ketoconazole are common.
Here is some additional information on Nizoral shampoo. And possible side effects that come with using Nizoral shampoo.
Changes in Your Hair
Changes to the structure of your hair should not occur because of a shampoo because its purpose is to help you clean your hair. A medicated shampoo has an additional function i.e. it should clean your hair while eliminating any adverse scalp condition on your head that is causing trouble for you. Sometimes, shampoos containing 2% ketoconazole cause changes to your hair although cases of such changes occurring are rare. Some people have reported experiencing some slight changes to their hair after using Nizoral. Drugs.com revealed these facts. It says that one of the changes reported is the appearance of hair texture that is abnormal in addition to oiliness. Other people reported a permanent loss of waves on their hair. They also reported hair discoloration, chemically damaged hair, and gray hair. Alopecia or hair loss was also a notable experience by a few individuals who had used the shampoo. In some cases, people reported that the Nizoral led to accelerated and uneven hair loss.
Skin-Based Side Effects
Although experiencing side effects on the skin after using Nizoral is unlikely, there exists a possibility that these effects will occur. Some of the possible effects include eczema, burning sensations, itching, the appearance of pimples and stinging sensations on the skin. Additionally, the shampoo can cause irritation to the mucous membrane and therefore, you should keep it as far away from your eyes as possible. Rinse your eyes with plenty of clean water if it gets into your eyes. The shampoo, as reported on Drugs.com, causes a low level of irritation as compared to shampoos that contain 2.5% concentration of selenium sulfide. Selsun Blue shampoo is one of the shampoos that contain such a high level of selenium sulfide.
There are reports of severe hypersensitivity after using Nizoral shampoo according to Drugs.com. In other words, allergic reactions to it occur. Common signs of these reactions include severe swelling, shortness of breath and rashes. These reactions are serious and they require immediate medical attention as they can develop into anaphylaxis, which is a life-threatening condition. Drugs.com also reports milder forms of allergic reactions. They include contact dermatitis otherwise known as allergic skin inflammation.
The U.S. Food and Drug Administration (FDA) classified Nizoral as a Pregnancy Category C product. That means the shampoo underwent animal studies that discovered it could possibly harm a fetus. However, a human trial on the impact it has on fetuses is pending. Therefore, there is no available data on that issue. The animal tests involved pregnant rats and the data showed that birth defects occurred after the rats consumed a large amount of ketoconazole orally. From the data, it would only be prudent for pregnant women to use the shampoo only when potential benefits greatly outweigh possible risks.
Nizoral shampoo is widely recommended for treating some scalp conditions because it is very effective. However, some people experience some adverse or mild side effects from using it. Individuals who experience any side effects should always report this to their doctor and seek an alternative route to assist them to treat the scalp condition that they may be experiencing.
