Overview

What is Fluconazole for thrush?

Fluconazole 150mg is an oral tablet that can treat many types of candidiasis - including the infection around your mouth or genitals.

Fluconazole is actually administered by doctors to treat candidiasis in other parts of your body. However, if you are sure that you have oral and genital thrush, you can buy Fluconazole online and take it yourself.

Thrush, or candidiasis, is a common fungal infection that can affect various parts of your body, including your mouth and genitals. It can make the affected area feel itchy and sore, and you may notice some unusual discharge or redness. If you suspect that you are suffering from thrush and haven’t had it before, you should first see a doctor to confirm the diagnosis.

Many women experience thrush more than once in their life. If you have had this type of infection before and are sure that this is the same infection, you can buy Fluconazole from HEBA Online Pharmacy today.

How long does Fluconazole take to work?

It can take a while for Fluconazole to work. If you have genital or oral thrush, you should start to see results in 7 days or less if the infection is mild. However, if your infection is more serious, it may take up to two weeks to notice a difference.

Directions

Fluconazole dosage
For genital candidiasis, your Fluconazole dosage will probably start at 150mg dose. You may need to increase or reduce your dosage depending on your infection. Treatment may last a few weeks.

For non-genital candidiasis, your dosage could start at 50mg and go up to 400mg, depending on the severity of your condition. Again, the course may last several weeks.

How to take Fluconazole
There are many possible ways to take Fluconazole, depending on your age, the severity of your thrush, what type of thrush you have, and any other medical conditions. The most common method involves taking a tablet.

How often can you take Fluconazole?
Usually, Fluconazole is only taken once per day without food. If you only need 150mg of the medication each day, you will only need to take one Fluconazole tablet each day. However, if you have a higher prescription, you may need to take more than one Fluconazole 150mg tablet.

Side Effects

Fluconazole side effects
As with all medications, there is a small risk of side effects when you take Fluconazole tablets. There are a few common side effects and some more serious ones that you should be aware of.

Common side effects
Nausea, diarrhoea, and vomiting
Headaches
Stomach cramps or pain
Change of your sense of taste
Dizziness
Rash
If these side effects are mild, you should be safe to wait and see if they go away. However, if any of these side effects are more intense or don’t go away, speak to a doctor or pharmacist for advice immediately.

Serious side effects
Keep your eye out for these serious side effects:

Severe rash, particularly if you have a weaker immune system
Liver damage symptoms, such as dark urine, intense vomiting or nausea, yellowing of the skin, severe and unusual itching, light stools
Issues with your adrenal glands, including muscle weakness, fatigue, stomach pain, or loss of appetite
Heart rhythm problems, like dizziness, seizures, fainting, a fast and irregular heart rate, palpitations. These issues can lead to torsades de pointes, a life-threatening heart problem
You begin to bruise more easily or get infections more easily

If you experience any of these serious side effects or feel like your symptoms are life-threatening, seek medical attention immediately.

Frequently asked questions

  • Is thrush an STI?

    Thrush isn’t a sexually transmitted infection (STI), but it can be triggered and sometimes passed on through sex. It's important to note that some STIs can cause symptoms similar to those of thrush, such as genital itching and discharge.

    If you are experiencing these symptoms and have had unprotected sex, it's important to get tested for STIs to rule out any potential infections by booking a visit to your local sexual health clinic.

    Practising safe sex and getting regular STI testing can help reduce your risk of both conditions.

  • Do men get thrush?

    Men can also get thrush, not just through having sex with someone who already has it (although this is the most common way), but through a disturbance of good bacteria. Just as a woman’s vagina can make a nice home for candida (the fungus previously discussed), so can the nice warm moist area of the penis. In men, thrush can cause redness, itching, and irritation on the penis. It may also cause a white, lumpy discharge that resembles cottage cheese.

  • Can I use a tampon when I have a thrush infection?

    It's generally recommended that you avoid using tampons until the infection has cleared up. This is because tampons can irritate the vaginal area and potentially worsen symptoms of thrush. Additionally, tampons can absorb medication used to treat thrush, making it less effective.

    Instead of using tampons, it's recommended that you use sanitary pads or panty liners until your thrush infection has been fully treated. You may also want to consider wearing loose-fitting clothing made from breathable fabrics like cotton, which can help reduce irritation and promote healing.

  • Does thrush come back after treatment?

    Thrush can sometimes come back after treatment, especially if the underlying cause of the infection is not addressed. For example, if thrush is caused by a weakened immune system or an uncontrolled medical condition like diabetes, it may be more likely to recur. Additionally, if you do not complete the full course of medication prescribed for your thrush infection, it may not be fully cleared up and could return.

    To prevent thrush from coming back after treatment, it's important to address any underlying health issues that may be contributing to the infection.

  • Is thrush contagious?

    Thrush is not typically considered a contagious condition. However, it's important to note that some types of yeast infections can be spread through sexual contact. For example, men can develop thrush on the penis after having unprotected sex with a partner who has a vaginal yeast infection.

    Additionally, babies can sometimes develop thrush after coming into contact with yeast in their mother's breast milk. If you are concerned about the potential for thrush to be spread to others, talk to your GP about steps you can take to reduce the risk of transmission and maintain good overall health.

  • Can I have sex when I have thrush?

    If you have thrush, it's generally recommended that you avoid having sex until the infection has cleared up. This is because sexual activity can cause further irritation and discomfort in the affected area, potentially prolonging the healing process. Additionally, engaging in sex while you have thrush may increase the risk of passing the infection to your partner, especially if you're not using barrier protection like condoms. Once your symptoms have resolved and you've completed the full course of treatment prescribed by your doctor, it should be safe to have sex again.

  • Why is my vagina itching?

    Vaginal itching is a common symptom that many women experience at some point in their lives. It can be caused by a variety of factors, ranging from mild irritations to more serious medical conditions. Some common causes of vaginal itching include yeast infections, bacterial vaginosis, sexually transmitted infections, and skin irritations from soaps, detergents, or personal care products.

    If you're experiencing vaginal itching, it's important to pay attention to any accompanying symptoms and consult your doctor for a proper diagnosis. They can help determine the underlying cause of your discomfort and recommend the most appropriate treatment plan. In some cases, over-the-counter remedies may be sufficient to alleviate itching, while other situations may require prescription medications or further medical intervention. By addressing the root cause of the itching, you can work towards finding relief and maintaining good overall health.
