AndroGel Travel & Timezone-Shift Protocols: The Complete Clinical Guide

Does the label give a timezone-shift rule?

No. The AndroGel 1% label says the recommended starting dose is 50 mg of testosterone applied once daily in the morning to the shoulders and upper arms and/or abdomen, preferably at the same time every day, and that the dose can be adjusted to 75 mg or 100 mg based on serum testosterone [1]. The patient instructions say to apply AndroGel 1% at the same time each morning, after showering or bathing [1]. The label does not set out what to do when a trip moves the traveler's morning by several hours, and it contains no travel schedule [1].

What the label says about applying the gel

The label says to apply AndroGel 1% to clean, dry, healthy, intact skin of the upper arms and shoulders and/or abdomen, limited to the area that a short-sleeve T-shirt would cover, and not to the genitals, chest, armpits, knees, or back [1]. After applying, the site should be allowed to dry before dressing, hands should be washed thoroughly with soap and water, and fire, flames or smoking should be avoided until the gel has dried because alcohol-based products, including AndroGel 1%, are flammable [1]. The label advises avoiding swimming or showering for at least 5 hours after application [1].

Close contact matters more than the clock

The boxed warning is about secondary exposure. Virilization has been reported in children who were secondarily exposed to testosterone gel, and children should avoid contact with unwashed or unclothed application sites [1]. The label also says AndroGel 1% is contraindicated in women who are pregnant because it can cause virilization of the female fetus [1].

The label lists these precautions: wash hands right after application, cover the application site with clothing such as a T-shirt after the gel has dried, wash the site thoroughly with soap and water before any situation in which direct skin-to-skin contact is anticipated, and, if unwashed or unclothed treated skin touches another person, wash the general area of contact on that person with soap and water as soon as possible [1]. It says the gel should be promptly discontinued until the cause is identified if virilization in a child or woman is suspected [1].

Sport rules are a separate question

In the US, AndroGel 1% is labeled CIII, and the label says testosterone is a Schedule III controlled substance [1].

In WADA-governed sport, testosterone is an S1 anabolic agent prohibited at all times, in and out of competition [2]. A prescription does not make it permitted; an athlete needs a Therapeutic Use Exemption [2].
