Penicillin reduces the risk of streptococcal throat infections and attacks of rheumatic fever in people who have already had a bout of rheumatic fever

Rheumatic fever is a rare complication of throat infection, that can damage the heart. People who have had rheumatic fever can suffer from it again following streptococcal throat infection if they do not receive regular penicillin. Penicillin for prevention can be given by injection or as tablets. Taking tablets is easier but might not work as well as injections. The review of trials compared different ways of giving penicillin. Penicillin seemed to work better as injections than as tablets. Injections given every two or three weeks worked better than when given every four weeks. However, more research is needed.

Fever in children: How can you reduce a fever?

When children have a fever, they don't always need to be given medication to lower it. But it can be a good idea to treat the fever if they are feeling extremely unwell or the fever is very high.It isn’t always clear whether the child's symptoms are being caused by the fever or by an underlying illness. So lowering the fever won't necessarily make them feel better.There are basically two ways to lower a fever: using medication or applying a cooling treatment from outside the body Some parents hope that they will be able to prevent febrile seizures with medication. But there is a lack of good research on whether fever-lowering medication can actually prevent febrile seizures.Many parents also try homeopathic products, including aconitum D12, belladonna D12 or chamomilla D12. But there is no scientific proof that these homeopathic treatments are at all effective.
