counteraction

edit

Triamcinolone acetonide and econazole cream

High dose of this product is easy to cause diabetes, digestive tract ulcer and Cushing-like syndrome, and has a strong inhibitory effect on hypothalamus-pituitary-adrenal axis. Concurrent infection is the main adverse reaction.

1. Long-term use of high-dose corticosteroids can cause metabolic disorders of water, salt, sugar, protein and fat: centripetal obesity, full moon face, hirsutism, weakness, hypokalemia, edema, hypertension and diabetes. , clinically known as Cushing's syndrome. These symptoms can be cured without special treatment. Generally, it will gradually subside after stopping the drug and return to normal after several months or a long time. If necessary, antihypertensive and hypoglycemic drugs can be used, and symptomatic treatments such as low pressure, low sugar and high protein diet and potassium supplementation can be given. Therefore, patients with hypertension, arteriosclerosis, renal insufficiency and diabetes should be properly supplemented with vitamin D and calcium, and corticosteroids should be used with caution.

2. Induce or aggravate infection: Corticosteroids have anti-inflammatory effect, but no antibacterial effect, which can reduce the body's anti-infection ability and is conducive to the growth, reproduction and spread of bacteria. Therefore, long-term use of glucocorticoids can induce infection or expand or spread the potential infection focus in vivo, and also spread the original static tuberculosis focus. Attention should be paid to the change of illness and whether there is any phenomenon of inducing infection during medication, and anti-infection treatment should be given at the same time.

3. Induce or aggravate peptic ulcer: Glucocorticoid can not only hinder tissue repair and delay tissue healing, but also increase gastric acid and pepsin secretion, reduce gastric mucus secretion, reduce gastric mucosal resistance, induce or aggravate gastric and duodenal ulcer bleeding, and even cause digestive tract perforation.

4, nervous system symptoms: excitement, insomnia, individual patients can induce psychosis, epilepsy patients can induce seizures. Therefore, psychotic patients, mental patients and epileptic patients should be banned.

5. Adrenal cortex atrophy or dysfunction: Long-term use of such drugs will affect the secretion of adrenocorticotropic hormone in hypothalamus and anterior pituitary gland, reduce the secretion of endogenous glucocorticoid or lead to adrenal cortex dysfunction, thus causing negative feedback. Once you encounter stress, such as bleeding and infection, you may experience dizziness, nausea, vomiting, hypotension, hypoglycemia or hypoglycemia coma.

6, rebound phenomenon and withdrawal symptoms: long-term use of hormonal drugs, when the symptoms are basically controlled, if the reduction is too large or suddenly stop taking drugs, the original symptoms or rapid aggravation can occur, this phenomenon is called rebound phenomenon. This is because the patient is dependent on hormones or the symptoms are not completely controlled. The treatment is to restore the dosage of hormone, and then gradually reduce it after the symptoms are controlled.

Treatment of eczema

edit

The World Health Organization (WHO) clearly pointed out in its guidance document on immune desensitization therapy that "immune desensitization therapy is the only fundamental therapy that can completely treat allergic eczema". The authoritative organization of international allergy research also puts forward that "high-quality standardized desensitizer should be used, and the best allergy treatment scheme should be adopted at the same time, including removing eczema allergen, immune repair of patients, symptomatic drug treatment of allergic eczema complicated with skin inflammation, and standardized desensitizer immunotherapy, which is referred to as" four in one and four therapy "scheme.

First, we should try to find allergens. Sometimes allergens are difficult to find, and they may not be clear, because people are exposed to too many things. You can record what you ate three days ago when you get sick from your mouth. If you eat something many times, your rash will get worse. Remember not to eat in the future. In addition, we should pay attention to environmental factors. Don't go where there are many flowers and pollen. Wear a mask when going out in pollen season. There are also common allergies, such as allergies to frames and allergies to the decoration of belts, which should be avoided. Because you start to feel itchy after using a cosmetic, it generally means that you are allergic to the ingredients in the cosmetic, so don't use this cosmetic. This is prevention first, try to find the reason. Can't find the reason. Try to avoid some allergic factors in life.

Second, eczema can be itchy, and scratching often aggravates skin lesions. In fact, dermatitis tickles more and more, causing a vicious circle. So, don't scratch when it itches, it tends to tickle more and more.

Third, see a doctor. You can take some antiallergic drugs for rash and chlorpheniramine and antihistamine for severe itching. Doctors will prescribe some drugs for external use, the most common being corticosteroids. There are more than 20 kinds of hormone drugs, and the hormones are strong and weak. We advocate not using the strongest medicine at first. The strongest medicine is not suitable for long-term use and has side effects. You can also use some topical ointments and potions.
