What are Nystatin Tablets for?
Nystatin tablets are specifically formulated for treating non-esophageal mucus membrane gastrointestinal (GI) candidiasis, which is a fungal infection of the digestive tract. The medication works locally within the gut to combat the overgrowth of Candida species and is minimally absorbed into the bloodstream. This means it is not effective for systemic (body-wide) fungal infections and is considered a safe and effective treatment for targeted GI issues.
How to Take Nystatin Tablets
For optimal effectiveness and to prevent relapse, Nystatin tablets should be taken exactly as prescribed by your doctor. A typical schedule for adults involves taking the tablets multiple times a day to ensure a consistent level of medication is active in the GI tract. You should swallow the tablets whole with a glass of water.
- With or without food? You can take Nystatin tablets with or without food. However, if you experience gastrointestinal side effects like nausea or stomach upset, taking the medication with a meal may help alleviate these symptoms.
- Don't chew the tablets: Unlike the oral suspension form used for mouth thrush, the tablets are designed to be swallowed whole. Chewing the tablets is not necessary for treating intestinal infections.
- Consistency is key: Take your medication as directed at regular intervals each day to establish a routine. This helps maintain a stable concentration of the antifungal in your gut, improving treatment efficacy.
The Importance of Completing the Full Course
One of the most critical aspects of taking Nystatin is completing the entire prescribed course of treatment, even if your symptoms start to disappear after a few days. Stopping the medication prematurely can have serious consequences:
- Relapse: The infection may not be fully eradicated. The remaining fungal cells can multiply again, causing the infection to return.
- Increased Resistance: Stopping treatment too early gives any surviving fungi an opportunity to develop resistance to the medication, making future infections harder to treat.
- Prolonged Symptoms: An incomplete course can lead to prolonged or recurring discomfort, necessitating a new, and potentially longer, treatment regimen.
Duration of Treatment
The total duration of Nystatin tablet therapy can vary depending on the severity and location of the infection. While symptomatic relief may occur within a few days, treatment is often continued for a period after clinical cure is observed to ensure complete eradication of the fungus. A typical course may last for several days to a few months. Always follow your doctor's specific instructions regarding the length of your treatment.

Addressing Potential Side Effects
Like most medications, Nystatin can cause side effects. The most common ones are typically gastrointestinal in nature, including nausea, vomiting, diarrhea, or stomach pain. If you experience these effects, try taking the tablets with food. For more persistent or severe symptoms, it's best to consult your doctor. In rare cases, allergic reactions can occur, presenting as a rash, hives, or swelling of the face, tongue, or throat. This requires immediate medical attention.
When to Consult Your Doctor
It's important to keep your healthcare provider informed about your progress and any issues you encounter during treatment. You should contact your doctor if:
- Your symptoms do not improve after several days of treatment.
- Your condition gets worse at any point.
- You experience signs of an allergic reaction.
- You have persistent or severe gastrointestinal side effects.
- You are unsure whether to continue or stop the medication based on symptom resolution.
Conclusion
Knowing when should I take Nystatin tablets is straightforward but requires strict adherence to your doctor's instructions. As a potent, locally-acting antifungal for the gastrointestinal tract, the key to its success lies in consistent dosing and completing the entire course, even after symptoms subside. By taking the tablets as directed with or without food and following your healthcare provider's guidance on duration, you can effectively combat intestinal fungal infections and prevent recurrence. Always remember that this medication is not for systemic infections and that any concerning side effects should be reported to a medical professional.
