In terms of internal medication after fungal infection, the two most commonly used medications are Itraconazole capsules and terbinafine hydrochloride tablets, both of which are more commonly used and safer. However, before using the drugs, it is recommended that liver and kidney function tests must be done, especially if they must be taken with normal liver function. This is because these drugs are metabolized through the liver and a process is required for the treatment of fungal infection-like diseases. If used in the case of poor liver function, it may lead to further aggravation of liver function damage, or otherwise normal liver function after taking the drug, so be sure to do the relevant checks regularly.
