Understanding Fluconazole 200 mg
Fluconazole, sold under brand names like Diflucan, is an antifungal medication that works by stopping the growth of certain types of fungi. The use of fluconazole, including the 200 mg strength, is determined by the type and severity of the fungal infection being treated and the patient's medical history. The duration of therapy can range from a single dose for some conditions to several weeks or months for more serious infections. It is important to follow the specific instructions provided by a healthcare professional for each individual case.
Administration Guidelines for Fluconazole 200 mg
Proper administration is key to the drug's effectiveness. Whether your prescription is for a tablet or a liquid suspension, these guidelines will help ensure you take it correctly:
- With or Without Food: Fluconazole can be taken with or without food. If it causes stomach upset, taking it with a meal might help alleviate the discomfort.
- Consistency is Key: It is best to take your medication at the same time each day to maintain a consistent level of the medicine in your body.
- Tablet Form: If you are taking the tablet form, swallow it whole with a drink of water. Do not chew or break the tablets.
- Liquid Suspension: For the oral liquid suspension, shake the bottle well before each use. It is crucial to measure the dose using the special measuring device or spoon provided by your pharmacist, as household spoons are not accurate and can lead to incorrect dosing.
- Complete the Full Course: Do not stop taking the medication early, even if your symptoms improve. Stopping treatment prematurely can result in the infection returning, and it may be more resistant to treatment in the future.
What to Do if You Miss a Dose
If you miss a dose of Fluconazole, take it as soon as you remember. However, if it is almost time for your next scheduled dose, skip the missed one and continue your regular dosing schedule. Do not take a double dose to make up for the missed one, as this can increase the risk of side effects.
Potential Side Effects of Fluconazole 200 mg
While many people tolerate fluconazole well, some may experience side effects. It is important to be aware of them and know when to seek medical attention.

-
Serious Side Effects (Contact your doctor immediately)

- Serious Allergic Reaction: Symptoms such as rash, severe itching, swelling of the face, tongue, or throat, or trouble breathing.
- Heart Rhythm Changes: Including a fast or irregular heartbeat, severe dizziness, or fainting, particularly if you have pre-existing heart conditions or take other QT-prolonging drugs.
- Skin Reactions: Redness, blistering, peeling, or a spreading rash.
Important Precautions and Warnings
Before starting fluconazole, discuss your full medical history and all medications you are taking with your doctor. This is particularly important for individuals with:
- Liver or kidney disease: Fluconazole is metabolized by the liver and eliminated by the kidneys, so dosage adjustments may be necessary for patients with impaired function.
- Heart problems: Individuals with certain heart conditions or a family history of QT prolongation are at a higher risk of heart rhythm issues.
- Pregnancy and Breastfeeding: Chronic, high doses of fluconazole have been associated with congenital abnormalities if taken during the first trimester. Women who can become pregnant should use effective birth control during treatment and for at least one week after the last dose. While it passes into breast milk, it is unlikely to harm a nursing infant at recommended doses. Always consult your doctor.
- Alcohol Consumption: Avoid alcoholic beverages while taking fluconazole, as it can increase the risk of liver damage.
- Drug Interactions: Fluconazole interacts with numerous medications. It is essential to inform your doctor if you are taking any other drugs, including over-the-counter and herbal products.
