What to do if you are allergic to metronidazole

Metronidazole is a drug used to treat or prevent systemic or local infections caused by anaerobic bacteria. However, for some people with allergies, metronidazole may be an allergen, causing allergic reactions. Metronidazole allergy is a typical drug allergy, and stopping the allergic drug first is the basis.

1: If a drug allergy reaction occurs, the patient should immediately stop taking the suspected drug and go to the hospital for prompt diagnosis and treatment.

2: If the allergic reaction is mild and you have anti-allergic drugs (such as Claritin, Prolamine, Cetirizine, etc.) at home, you can use them immediately according to the instructions.

3: If the patient has shortness of breath, pale face, cold hands and feet, and low blood pressure, he should be sent to the hospital for emergency treatment immediately. Before going to the hospital, try to quickly let the patient lie flat on the ground, let the head tilt to one side, unbutton the clothes, and ensure that breathing is unobstructed. If some simple first aid measures can be taken, such as clearing secretions from the mouth and nose and breathing oxygen, it will be more conducive to the relief of the shock patient.

1: Before taking any medication, first make a clear diagnosis. Do not use multiple medications before the condition is fully understood, thinking that one of the medications will be effective. This can easily lead to unnecessary drug reactions.

2: You should be fully familiar with the ingredients, properties, indications, contraindications, side effects, and incompatibility of the drugs you use, and avoid abusing, misusing, or overusing them.

3: Before taking the medicine, the patient should be asked in detail whether he has a history of drug allergy, especially for those with allergic constitutions. For those who have had drug allergic reactions, attention should be paid to the occurrence of cross-sensitivity or multi-source allergic reactions.

4: Medication should be planned, the dosage should not be too large, the types should not be too many, the duration should not be too long, and regular observation should be conducted, especially when using drugs with certain toxicity, such as immunosuppressants, anti-cancer drugs, etc., close observation should be conducted, and blood counts should be checked frequently.

People often cannot tolerate certain drugs. For example, patients with kidney disease should be cautious when using heavy metal drugs. During medication, you should pay attention to some warning symptoms or intolerance phenomena, such as skin itching, erythema or fever, and consider stopping the drug immediately if they occur.
