Let's have a look at how they each work, how to use them and the possible side effects.
Topical corticosteroids are a popular choice of foot and ankle rash treatment.

Mild topical corticosteroids are usually available over the counter from a pharmacist but anything stronger will require a prescription. You should always use the lowest potency corticosteroid that is effective for your foot or ankle rash.
It is important to be aware that topical corticosteroids will not cure the underlying problem and foot and ankle rash symptoms may flare-up when treatment is discontinued. However, they can provide excellent symptomatic relief of inflammation and itching and help control the problem, making them a very important part of foot and ankle rash treatment.
Topical corticosteroids may also contain another active ingredient, anti-microbials, for treating bacterial or fungal infections such as infected Eczema or Athlete’s Foot.
Anti-microbials are typically applied two to three times daily for a short period, usually 5-7 days, as part of the foot or ankle rash treatment. Longer-term use is not advised as it can lead to antimicrobial resistance.
Most topical steroids only need to be used once or twice a day for foot or ankle rash treatment.

Topical corticosteroid dosage is measured in Finger Tip Units "FTU", the distance from the last finger crease to the finger tip on your index finger.
when applied correctly 1 FTU covers approximately the same area as two hands laid flat with the fingers together, leaving a thin, glistening layer over the applied area. Thinner areas of skin such as eyelids will require less cream or ointment than thicker areas such as the soles of the feet.
Typical dosages when using topical corticosteroids for rashes are:
Child aged 4 years: should use approximately 1/3 of the adult amount
Infant 6 months to 1 year: should use approximately 1/4 of the adult amount
When used correctly, there are very few side effects from using topical corticosteroids for foot and ankle rash treatment. The most common side effect is a temporary stinging or burning sensation when applied, but that usually settles as your skin gets used to the treatment.
Side effects are more likely when using a more potent corticosteroid or with long term use (more than one to two months of continuous use) and typically affect young children and the elderly.
Side effects of topical corticosteroid used for foot rashes include:
Oral anti-histamines are really helpful for treating itchy foot rashes and are usually available over the counter without a prescription.
Anti-histamines work particularly well for allergic contact dermatitis and eczema where the skin mistakes harmless substances such as pollen as potential harmful. The skin responds by producing histamine, an immune system protein.
Anti-histamines are a great way to reduce the itching and scratching cycle and when discomfort is interfering with daily life.
Oral anti-histamines fall in to two categories:
First generation antihistamines are particularly useful if itching and discomfort is affecting your sleep, a common problem with eczema. Care should be taken though, particularly if you take them during the day due to their sedating affect.
