Most hormonal medication therapy is monitored with periodic blood tests. This helps your doctor make sure that you take the right amount of the hormonal drug. Ideal doses vary from person to person. If the dose of hormonal medication is too small for you, it will not do its job correctly. If the dose is too high, it may cause side effects. Either of these situations can be serious and potentially life threatening. Risks and potential complications of hormonal therapy include: Complications from too little of a hormonal medicationSide effects from too much of a hormonal medicationSide effects not related to dose. For example, insulin injections can cause skin changes that are not related to the dose. These changes include abnormal bumps, dents or thickening of your skin.
