How to treat a rash on the skin depends on the cause of its occurrence.
Aetiological treatment of rashes is selected taking into account the underlying disease (atopic dermatitis, contact dermatitis, urticaria, insect allergy, drug allergy). It provides for:
- elimination of cause-significant allergens;
- systemic pharmacotherapy;
- local treatment.
Elimination of cause-significant allergens implies the use of protective regimes and individual elimination diets.
When carrying out systemic pharmacotherapy, drugs from different groups are used.
[How to treat a rash with antiallergic drugs?
- H1-receptor blockers of histamine are used in atopic dermatitis, allergic contact dermatitis, drug, food or insect allergy.
- H1-receptor blockers of the first generation: klemastin intramuscularly or intravenously 2 ml 1-2 times in knocking for 7-10 days, chloropyramine intramuscularly or intravenously 1 ml 1-3 times a day for 7-10 days.
- Blockers of H1 receptors of the second generation: desloratadine orally 5 mg once a day, fexofenadine oral 180 mg once a day or cetirizine orally 10 mg once a day until the appearance of clinical effect. Dimethinden is inside 20-40 drops three times a day for 7-10 days, loratadine by 10 mg once a day before the appearance of the clinical effect, mebhydroline inside 50 mg 3 times a day for 7-10 days, mequitazine inside 10 mg once a day or 5 mg twice a day, ebastin inside 10-20 mg once a day until the appearance of a clinical effect.
How to treat a rash with glucocorticoids?
Systemic glucocorticoids are used for acute, severe atopic dermatitis, allergic contact dermatitis, drug allergy, insect allergy: dexamethasone intramuscularly or intravenously, 6-8 mg once a day, or prednisolone intramuscularly 30-60 mg once a day for 3-7 days .
Local treatment of rash with glucocorticoids is prescribed for moderate to severe atopic dermatitis, food and drug allergies. With hives, this type of treatment is not used. Assign external glucocorticoids of varying degrees of activity: clobetasol, betamethasone, budesonide, fluticasone, halomethasone, mometasone, fluocinolone acetonide, mazipredon, dexamethasone, prednicarbat, hydrocortisone, prednisolone. The drugs are used 1-2 times a day for 7-21 days.
External treatment of rashes with combined preparations: glucocorticoids in combination with antibiotics, antiseptics, antifungals are used in complicated forms of atopic dermatitis, allergic contact dermatitis, drug and food allergies. Various combination medicines are used for treatment.
Antibacterial treatment of rashes is prescribed for a secondary bacterial infection with atopic dermatitis, allergic contact dermatitis, drug and food allergies. Treatment of bacterial infection should begin with external antibacterial agents: mupirocin, fusidic acid. Apply drugs 1-Z times a day for 7-30 days. It is possible to use combined external preparations.
Systemic antibacterial drugs are recommended for insufficient effectiveness of external therapy and for the spread of bacterial infection on the vast surface of the body. Drugs of choice consider macrolides: azithromycin inside but 500 mg once a day for 3-5 days, clarithromycin inward by 250 mg twice a day for 7-10 days, roxithromycin inward at 150 mg 2 per day and during 7-10 days or erythromycin orally in 0.25-1 g 4 times a day for 7-10 days.
Antifungal drugs are prescribed when attaching fungal infection in atopic dermatitis, allergic contact dermatitis, drug and food allergies. Treatment of fungal infection should begin with external antifungal and combined agents. If the external treatment is ineffective, systemic antifungal agents are used.
