Nystatin is an antifungal medication that has been widely used for decades to treat various fungal infections, particularly those caused by Candida species. As with any medication, it's essential to be aware of the potential side effects associated with nystatin. In this article, we'll discuss both common and rare side effects, as well as provide information on what you should know when taking this medication.
Nystatin works by binding to the fungal cell membrane, altering its permeability, and ultimately leading to cell death. This mechanism of action makes it effective against a range of fungal infections, including oral thrush, vaginal yeast infections, and cutaneous candidiasis. However, like all medications, nystatin can cause side effects, some of which are more common than others.
Common Side Effects of Nystatin
The most common side effects of nystatin are generally mild and temporary. These may include:
- Gastrointestinal upset, such as nausea, vomiting, and diarrhea
- Abdominal pain or cramping
- Headache
- Dizziness or lightheadedness
- Skin rash or itching
These side effects are usually self-limiting and resolve on their own once the treatment is completed. However, if they persist or worsen, it's essential to consult with your healthcare provider.
Gastrointestinal Side Effects
Gastrointestinal side effects are among the most common adverse reactions to nystatin. These may include:
| Side Effect | Frequency |
|---|---|
| Nausea | 10-20% |
| Vomiting | 5-15% |
| Diarrhea | 5-10% |
These side effects can be managed by taking the medication with food or adjusting the dosage. If gastrointestinal side effects persist or worsen, your healthcare provider may recommend alternative treatments.
Rare but Serious Side Effects
While rare, nystatin can cause serious side effects, including:
- Allergic reactions, such as anaphylaxis or Stevens-Johnson syndrome
- Liver damage or elevated liver enzymes
- Nephrotoxicity or kidney damage
- Respiratory problems, such as bronchospasm or asthma-like symptoms
These serious side effects require immediate medical attention. If you experience any symptoms of an allergic reaction, such as difficulty breathing, rapid heartbeat, or swelling of the face, lips, or tongue, seek emergency medical help.
Liver Damage and Nephrotoxicity
Nystatin can cause liver damage or elevated liver enzymes in some individuals. This is more likely to occur in patients with pre-existing liver disease or those taking high doses of the medication. Similarly, nephrotoxicity or kidney damage can occur, particularly in patients with pre-existing kidney disease.
| Side Effect | Frequency |
|---|---|
| Liver damage | Rare (<1%) |
| Nephrotoxicity | Rare (<1%) |
Regular monitoring of liver and kidney function is essential for patients taking nystatin, particularly those with pre-existing conditions.
