Anyone taking oral steroids or a high dose of inhaled steroids for more than three weeks should be given a steroid treatment card . Small enough to keep in your purse or wallet, this card has room to record the details of your dose and your condition(s). This is so that if you ever need any medical treatment and you're not able to communicate (you're having an asthma attack, for example), the people treating you know you're taking prednisolone and can plan your treatment accordingly. If you are taking oral steroids, or high-dose inhaled steroids, for more than three weeks then you should never suddenly stop them.
Transdermal patches (adhesive patches placed on the skin) may also be used to deliver a steady dose through the skin and into the bloodstream. Testosterone-containing creams and gels that are applied daily to the skin are also available, but absorption is inefficient (roughly 10%, varying between individuals) and these treatments tend to be more expensive. Individuals who are especially physically active and/or bathe often may not be good candidates, since the medication can be washed off and may take up to six hours to be fully absorbed. There is also the risk that an intimate partner or child may come in contact with the application site and inadvertently dose himself or herself; children and women are highly sensitive to testosterone and can suffer unintended masculinization and health effects, even from small doses. Injection is the most common method used by individuals administering AAS for non-medical purposes.
