You will need to see your doctor regularly over the course of your treatment. They will want to make sure that you are getting the right treatment and dose of testosterone. Ideally you should have another blood test 2 weeks after starting Testogel® 16.2 mg/g gel to ensure you are on the correct dose. However, your doctor may want to observe your symptom response to treatment before doing another blood test.1,2

Depending on your circumstances, your doctor may require some blood tests throughout the course of your treatment. These tests will continue to check your testosterone levels and other blood components, which may indicate if you are experiencing some side effects.1,2

It’s important that you speak to your doctor about how you are feeling

Blood tests cannot monitor all aspects of your treatment though, for example your mood or libido/sex drive, or if you are experiencing certain side effects from the treatment. Discussing how you feel with your doctor can help them make the right treatment decisions with you.

Our tips for talking to your doctor provide great advice about starting any difficult conversations with your healthcare provider.

You can also review your own symptoms and see if they are changing over time, with the Ageing Male’s Symptoms (AMS) questionnaire.
