Hi, Erythromycin is an antibiotic that can be effective for treating bacterial skin infections, including pimple boils. Dicloxacillin is also another antibiotic used for the treatment of skin infections. However, it is important to note that antibiotics should be taken as prescribed by a doctor or a healthcare professional. While consulting a pharmacist is helpful, it is not a substitute for medical advice from a qualified healthcare provider. It is important to consult a doctor if you have not already done so, to ensure that you are receiving appropriate treatment for your skin infection. In terms of the duration of treatment, it is important to follow the recommended course of antibiotics as prescribed by a healthcare professional. Taking antibiotics for longer or shorter than recommended can lead to antibiotic resistance, which can make future infections more difficult to treat. Therefore, it is important to complete the full course of antibiotics as prescribed by your doctor. If you have any concerns or questions about your treatment, it is important to speak with your doctor or a qualified healthcare professional. Take care. Hope I have answered your question.
