There is usually no fixed oral duration for ashwagandha tablets, and patients can take them continuously as long as their liver function is regularly monitored and there are no significant abnormalities in liver function while their condition requires it. Ashwagandha tablets are an antifungal drug that can be used clinically to treat a variety of skin diseases caused by fungal infections, commonly including ringworm of the head, ringworm of the body, and ringworm of the feet. Its common side effects are that it can cause neurogenic headache and abnormal liver function, and about 10% of patients can develop neurogenic headache. If the neurological headache is tolerated and there are no significant abnormalities in liver function on regular monitoring, ashwagandha tablets can be taken continuously. To prevent recurrence of the disease, ringworm usually needs to be taken orally for 8-10 weeks for ringworm of the head, 2-4 weeks for ringworm of the body, and 4-8 weeks for ringworm of the feet, and can be discontinued after laboratory tests indicate that the pathogenic bacteria have been completely eradicated. However, in view of the relatively high number of side effects of ashwagandha tablets, their clinical use is now decreasing and they are gradually being replaced by other newer antifungal drugs, such as itraconazole and terbinafine.
