Belladona overdose or not

My child is cheerful but he has become a little bit quiet after taking Belladona for 31-32 days. He is not aggressive.he is hyperactive but not very much.He likes to try almost every kind of food. He is playful but cannot carry out conversations.He cannot reply to a question or answer yes or no. .cannot tell his name ..but he used to respond to his name promptly before taking Belladona for 31 days.As I had mentioned before, a local homeopathic doctor had prescribed the dosage of belladona 30 for 21 days twice a day (2 pillules each time) and then prescribed Belladona 200 twice a day (4 pillules each time).He took 200 for 11 days.he stopped responding to his name while he was on belladona.

If you are asking about the symptoms of hyperactivity, reduced talk, less attention, not always following instructions. ..yes these were seen after the head injury which happened one and a half years back.but later he started to communicate using two words over the past few months. But no use of sentences or use of conversations from his side.He started following instructions well and he was never on any medicines. But recently someone suggested there are good homeopathic medicines to combat speech delay ..so we went to a homeopathic doctor who put him on Belladona for attention and improvement of speech. But we are worried because after having belladona for over one month he is not following his instructions well and not responding to his name. We heard that homeopathic medicines are safe but we cannot understand why this happened after taking Belladona? Was the dosage not suitable for him?One of my friends said Belladona 200 is not safe for a 3 year old child and he had taken it twice a day for 11 days. Hence the problem. Could you please help? Because we are very worried because the medicine has been stopped over 3 weeks but still he is not responding to his name.

Thanks. .it has been about 4 weeks he is not responding to his name after the medicine has been stopped. When we went to the doctor who had given this medicine and reported about the problem he just asked to stop the medicine and said nothing much

Thank you. My son is 3.5 yrs old. Should I give him black coffee?May I know how can I prepare his cup of coffee since he is a child?

After 2 months of stopping Belladonna, my son has started responding to his name but speech is not removing. Sometimes he becomes hyperactive.Before taking Belladonna he used to speak much more. Can an overdosage of Belladonna affect the brain and cause any life long damage?
I had always heard that homeopathic medicines are safe and do not have any side effects.

Thanks Dr.
