Many things can cause vaginal itching (vaginal pruritus) during and after your period. At any time during your menstrual cycle, infections, skin conditions, sensitivities, certain medications, or diseases may cause vaginal itching.
However, if you experience itching during your period, the culprits may be hormonal changes or allergies to tampons or other menstrual products. Treatment for vaginal itching depends on the cause.
This article covers reasons for vaginal itching during and after your period, how to manage the itching, and when you should see a healthcare provider.

If vaginal itching starts during your period, it could be due to hormonal fluctuations or sensitivities to the menstrual products you are using.
The menstrual cycle has three hormonal phases: follicular, ovulatory, and luteal. Your period is the beginning of the follicular phase. 
During this phase, the endometrium (uterine lining) is thick. However, the low levels of estrogen and progesterone during this phase cause the uterine lining to break down and shed. This shedding results in vaginal bleeding. 
While bleeding only lasts between three to seven days, the follicular phase lasts up to a couple of weeks. It ends when the level of luteinizing hormone surges. Hormonal fluctuations, especially low estrogen, can sometimes result in itching.
In addition, you may be sensitive or allergic to specific products, especially those that come in contact with your vulva or vagina during your period. Sensitivities may lead to itching.
Some common products that could lead to vulvar or vaginal itching include:

Scented items tend to cause more irritation on sensitive skin. So, if you have sensitive skin, you may want to stick to unscented menstrual products, soaps, and detergents made for people with skin sensitivities.

Vaginal itching can occur at any time during your menstrual cycle. Causes range from infection, skin conditions, medications, and cancer.
Bacterial vaginosis (BV) is a common condition where the normal balance of bacteria is disrupted. When you have BV, you have an unhealthy balance of bacteria in the vagina.
BV is the most common vaginal condition in people ages 15 to 44.
The exact cause of BV is unknown. However, it occurs most often in sexually active people. 
In addition to vaginal itching, BV causes other symptoms, including:
You can not treat BV at home. It requires a medical diagnosis and treatment with antibiotics. 
Trichomoniasis is a sexually transmitted infection (STI) that can cause vaginal itching. A parasite called Trichomonas vaginalis causes the condition.
Trichomoniasis infected more than 2 million Americans in 2018. In the U.S., it is the most common of all curable STIs.
Up to 70% of people with trichomoniasis do not exhibit symptoms. But, those who do have symptoms may experience the following:

Treating trichomoniasis requires prescription medication. If you suspect you may be infected, it’s essential to see a healthcare provider. In addition, after treatment, it’s possible to become reinfected. All sexual partners should receive treatment simultaneously to limit the likelihood of reinfection.
Vaginal yeast infection, also called vaginal thrush, is a fungal infection in the vagina. Vaginal yeast infections are caused by a fungus called Candida. This fungus usually lives in your vagina in healthy amounts. However, a yeast infection occurs when this fungus overgrows. 
Yeast infections are common. People most at-risk for developing them include those who are pregnant, take birth control pills, have diabetes, are immunocompromised, or are taking antibiotics.
Symptoms of thrush include:
Yeast infections are treated with anti-fungal medicine. 
Vulvovaginitis is inflammation or infection of the vulva and vagina. It can result in itching, pain, and discharge with odor. Yeast, bacteria, and STIs can cause it, but for some people, vulvovaginitis occurs more frequently during their period.
Dermatitis is a skin condition that causes itching and irritation. Allergies, sensitivities, or an inflammatory disease like eczema cause dermatitis. 
Contact dermatitis occurs when your skin reacts to a substance to which you are sensitive or allergic. Symptoms include itching, burning, and skin rash or blisters. The itching from dermatitis can be intense and disrupt a person’s ability to sleep or perform day-to-day tasks.
The best way to treat dermatitis is to prevent it. Therefore, try to identify the trigger and avoid it. In the meantime, topical steroids can help relieve itch and inflammation. Allergy testing may be a good idea to help narrow down allergens.
Psoriasis is an autoimmune skin condition that causes scaly, itchy patches on the skin. It can occur anywhere on the body—even the genitals.
Anyone can develop psoriasis, but it is not contagious. Instead, it occurs when your body’s immune system attacks your body’s tissues. 
Symptoms of genital psoriasis include:
Even if you treat psoriasis elsewhere on your body, it’s important to tell your healthcare provider about psoriasis on your vagina or vulva. That’s because the skin on your genitals is thinner and more sensitive. Therefore, your healthcare provider may suggest a different treatment for that area. 
Lichen planus is a condition that causes itchy bumps on the skin. Anyone can get lichen planus, but it is most common in middle-aged people. The cause of lichen planus is unknown. One theory is that it is an autoimmune disease.
Lichen planus bumps can occur anywhere on the skin, including the genitals. Symptoms of lichen planus include:
Antihistamines may relieve the itch associated with lichen planus. In addition, a healthcare provider may prescribe topical and systemic steroids. They may also suggest light therapy and retinoic acid. 
Lichen sclerosus is an inflammatory skin disorder that affects the vulva and perineum. Researchers believe it is caused by immune dysfunction, genetics, and hormones.
Not everyone with the condition experiences symptoms. Those who do may have vulvar itching and find that sex feels painful. In addition, the genitals may appear white, thin, and wrinkled.
Healthcare providers commonly use steroids to manage the symptoms. 
Atrophic vulvovaginitis is a condition where the skin of the vulva and vagina is dry and painful. It is most common in post-menopausal people. It also occurs during lactation, cancer treatments, and with some medications.
Symptoms of atrophic vulvovaginitis include:
Lubricants can often help with vaginal dryness, especially during sexual activity. In addition, healthcare providers routinely prescribe progesterone and estrogen hormone therapy.
Some medications can contribute to vaginal itching, including antibiotics, immune-suppressing drugs, and steroids. That’s because these medications can disrupt the normal balance of bacteria and yeast, leading to infection.
Less frequently, itching can be a symptom of any cancer, especially skin cancer. In addition, cancer treatment can sometimes cause itching.
Cancers that affect the genital area include:
Regular screenings help catch cancers in their early stages when they are most treatable. So, get pap smears and other recommended cancer screenings regularly. If you are undergoing cancer treatment and experiencing itching as a side effect, talk to your oncologist for treatment options. 
Fortunately, there are some things you can do to manage vaginal itching when it does occur. Sometimes you can control itching at home. Other times, you’ll need to see a healthcare provider for treatment.
Home remedies can help you manage the discomfort of vaginal itching. You might use them for minor situations that don’t require medical support, and you can also use them alongside standard medical care to soothe skin and provide relief. 
Home remedies include:
Applying aloe vera or coconut oil are also used to manage the symptoms of vaginal itching. These products should not be placed in the vagina or on the vaginal mucosa.
Medical treatment depends on the vaginal itching cause. A healthcare provider will first diagnose your condition and then prescribe treatment.
Treatment may include:
You should see a healthcare provider any time you are worried about your symptoms or have signs of infection. In addition, the following symptoms warrant medical attention:
Vaginal itching during and after your period may be caused by many things, including hormones, skin sensitivities, infections, STIs, and medications. Treatment depends on the cause but may include antifungals or antibiotics, steroids, and lubricants.
If you are experiencing vaginal itching during your menstrual cycle, you may be feeling embarrassed. Don't be. Rest assured, vaginal itching during and after your period is very common. Getting an accurate diagnosis is key to relieving your symptoms, so call a healthcare provider for treatment options. In the meantime, you may be able to find some relief with an oatmeal bath, cool compresses, and vaginal lubricants.

Since tampons contain many ingredients, it is possible to be allergic to them. Avoid products that have added chemicals, such as those with added fragrances. And discontinue use and talk to a healthcare provider if you notice symptoms after using tampons.
Some people, especially those with sensitive skin, may be sensitive to tampons. In addition, if you have vaginal dryness, tampons may irritate skin that is already irritated.
You can't be allergic to your period blood. However, rarely, people develop a condition called progestogen hypersensitivity, which is a reaction to their own body's progesterone. The skin condition occurs during a person's menstrual cycle.
Side effects from tampon use include the risk of developing toxic shock syndrome (TSS). In addition, some people are sensitive to tampon ingredients and may develop an itchy rash.
