What should I do if I feel itchy due to drug allergy?

Medicine is something that treats diseases. Most medicines are synthesized using chemical substances, and most of them are toxic. Long-term use is very harmful to the health of the body. For example, it can cause some allergic symptoms to the body. Among them, skin allergies are a common symptom. Let’s take a look at what to do if you feel itchy due to drug allergies? I hope everyone can understand.

Drug allergies often cause skin damage, with symptoms such as rash and itching on the skin. There may also be itching without an obvious rash, but some patients will experience more severe skin symptoms. Drug allergy can also easily cause systemic fever, which may occur before other skin symptoms or exist at the same time as other symptoms. In addition, drug allergy can easily cause rapid-type hypersensitivity reactions such as rhinitis, asthma, anaphylactic shock, or serious diseases such as hepatitis, allergic pneumonia, kidney disease, systemic lupus erythematosus-like reactions, hemolytic anemia and vasculitis, which seriously threaten the life and health of patients.

Generally, the disease can be cured in about a week.

2. Slightly more serious cases refer to those with more extensive rashes and accompanied by fever.
