Hi,
Though
Implanon can lead to some amount of
dizziness as side effect, usually this will subside during the first few months of the usage. As you are using the Implanon since 1 year and as you are having the dizzinessiness which is altered by the position and also
fainting attacks, these may not be directly related to the Implanon. Other causes also should be considered like vertigo as you mentioned and also any neurological abnormalities. Hence, it is better to consult your physician once and get examined.
By clinical examination the exact cause of your problem can be identified and depending on that if needed you can go for investigations like
hemoglobin levels, blood sugar levels, serum electrolytes, specific investigations like
audiometry, EEG, MRI brain, etc. with this work up the possible cause of a problem can be identified and treatment can be taken accordingly.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Sree Gouri S. R., OBGYN
