Most people who use Diflucan do not experience any negative side effects. Doctors prescribe Diflucan because they assess that the benefits that such treatment yields outweighs any likely unwanted effects.

If after taking Diflucan a sudden allergic reaction (anaphylaxis) occurs, with symptoms like swelling of the face, tongue, or throat making it difficult to breathe or swallow, or there is wheezing, hives, rash, blistering or peeling of the skin, call a doctor or 911 right away, or go to an emergency room immediately.

Some of the side effects that have been reported include:

• Headache
• Abdominal discomfort, diarrhea, vomiting, nausea
• Decreased appetite
• Insomnia, feeling drowsy
• Dizziness, sensation of spinning
• Sensations of tingling, pricking, or numbness
• Changes in the sense of taste
• Constipation, difficult digestion, flatulence

• Increased sweating
• Tiredness, general feelings of being unwell
• Fever

Not all side effects are listed here. If these or other unlisted symptoms persist or worsen, consult a healthcare provider or pharmacist.

Fungal infections (mycosis) can happen anywhere on the outer surfaces (skin or nails), as well as in the mucous membranes (mouth, urinary tract, vagina, and anus), the lining of the brain, and in the lungs. The symptoms of fungal infections depend on what kind of fungus it is, and the location.

Doctors can order tests such as skin samples, nail clips, blood, sputum, or urine samples. In more serious cases, where infection of the brain or spinal column may be suspected, a spinal tap can collect a sample of cerebral fluid for testing.

Some of the most common are:

• Athlete’s foot
• Groin itch
• Ringworm
• Candida yeast infections.
