Can you use penicillin for swollen glands?

Penicillin is an antibiotic that is effective against bacterial infections, but it is not appropriate for treating swollen glands unless the swelling is caused by a bacterial infection, such as strep throat. Swollen glands can result from various causes, including viral infections, which would not respond to antibiotics like penicillin. It's important to consult a healthcare professional for an accurate diagnosis and appropriate treatment based on the underlying cause of the swollen glands.
