How should I use testosterone buccal?

Follow all directions on your prescription label. Do not use this medicine in larger or smaller amounts or for longer than recommended.

You will use this medicine once in the morning and once in the evening (every 12 hours). The buccal tablet is placed above your upper teeth near the center of your mouth.

Carefully follow the application instructions that come with testosterone buccal. Ask your doctor or pharmacist if you have any questions.

One side of the buccal tablet is flat and one side is curved. The curved side fits against your gum, with the flat side facing out.

At the end of the 12-hour wearing time, remove the tablet gently to avoid scraping your gum.

While using testosterone buccal, you may need frequent blood tests.

-The chronological and skeletal ages must be taken into consideration, both in determining the initial dose and in adjusting the dose.
-This drug should be used only if the benefits outweigh the serious risks of pulmonary oil microembolism and anaphylaxis.
-Injections more frequently than every two weeks are not recommended.
