How to use Taro-Testosterone Gel:
- 1. Apply Taro-Testosterone Gel at the same time each day (preferably in the morning). Apply the prescribed amount of gel every morning as instructed by your healthcare professional. The amount of Taro-Testosterone Gel you need may be adjusted by your healthcare professional during treatment. Always follow your healthcare professional’s recommendations. You should be applying the gel yourself to avoid other people coming into contact with the gel.
- 2. Be sure your skin is completely dry before applying Taro-Testosterone Gel. If you take a bath or shower in the morning, apply Taro-Testosterone Gel after your bath or shower, once your skin is completely dry.
- 3. Apply Taro-Testosterone Gel only to your abdomen (stomach area), shoulders, and/or upper arms, as shown in the following diagram.
- Use a circular motion to rub in the gel for several seconds. Applying Taro-Testosterone Gel only to the areas shown helps ensure that your body will absorb the right amount of testosterone. Taro-Testosterone Gel may be applied to the same areas of the body each day. It is not necessary to alternate application sites.
- Never apply Taro-Testosterone Gel to your genitals (penis and scrotum) or to damaged skin.
- Only apply Taro-Testosterone Gel to healthy, normal skin. Taro-Testosterone Gel contains alcohol which may cause a burning sensation if it is applied to damaged skin. Avoid skin with open sores, wounds, sunburn, or irritation.
- Wash your hands immediately after application.
- It is important to wash your hands with soap and water right away to reduce the chance that any Taro-Testosterone Gel will spread from your hands to other people.
- If you get Taro-Testosterone Gel in your eyes, rinse your eyes right away with warm, clean water to flush out the gel. Get medical attention if you still have discomfort after rinsing the eyes thoroughly.
If you expect to have direct skin contact with someone else after applying Taro-Testosterone Gel you must wait at least 1 hour. After the hour has passed you must wash
- your application site(s) with soap and water before having any direct skin contact. This will reduce the chance that any Taro-Testosterone Gel will transfer to the other person.
- Let Taro-Testosterone Gel dry for a few minutes before you dress.
- This prevents your clothing from absorbing the gel or wiping the gel off your skin, ensuring that your body will absorb the correct amount of testosterone.
- Once the gel has dried, cover the application site with clean clothing. You can prevent transferring Taro-Testosterone Gel to other people by covering the application site with a long-sleeved shirt (cotton-polyester blend).
- Allow the gel to dry completely before smoking or going near an open flame. Taro-Testosterone Gel contains alcohol which is flammable.
- Wait 1 hour before showering or swimming. To ensure that Taro-Testosterone Gel is fully absorbed into your system, you should wait one hour after application before showering or swimming.
It is important that you read and follow the directions below on how to use Taro-Testosterone Gel properly:
- See Section A if you are using the Taro-Testosterone Gel Pump
- See Section B if you are using the Taro-Testosterone Gel packets
Section A: Using the Taro-Testosterone Gel Pump
- i)
Priming the pump:
Before using a new pump for the first time, you must prime the pump to remove the air. Up to five depressions may be needed before all of the air is removed and gel is discharged. The first two depressions that deliver any amount of gel are to be discarded by thoroughly rinsing the gel down the sink or discarding it in the household trash in a manner that prevents accidental application or ingestion by household members, especially children and breast feeding or pregnant women.
ii) Determining the number of full depressions (presses of the pump) needed for each dose:
Each full press of the pump delivers 1.25 g of Taro-Testosterone Gel. Please refer to the chart below to determine the number of full depressions required for the daily dose prescribed by your healthcare professional:
Prescribed Daily Dose | Number of Full Pump Depressions |
|---|---|
| 5 g | 4 |
| 7.5 g | 6 |
| 10 g | 8 |
iii) Number of days of treatment per pump (after priming):
The Taro-Testosterone Gel Pump contains enough gel to allow for priming and a set number of precise doses. Please refer to the chart below to determine the number of days of treatment each pump will provide based on your individual dose. Discard the pump afterwards.
| Prescribed Daily Dose | Number of Days of Treatment per Pump (after priming) |
|---|---|
| 5 g | 15 |
| 7.5 g | 10 |
| 10 g | 7.5 |
iv) Applying Taro-Testosterone Gel Pump to your skin:
Fully press the pump the appropriate number of times to deliver the daily dose prescribed by your healthcare professional. The gel should be delivered directly into the palm of your hand and then applied to the desired application sites, either one pump depression at a time or upon completion of all pump depressions required for your daily dose. Alternatively, the gel can be applied directly to the application sites. Application directly to the sites may prevent loss of the medicine that can occur during transfer from the palm of your hand onto the application sites.
Section B: Using the Taro-Testosterone Gel packet
- i) Opening the packet:
Open one Taro-Testosterone Gel aluminum foil packet by folding it along the top edge and carefully tearing it open.
- ii)
Applying Taro-Testosterone Gel to your skin:
- • Gently squeeze the gel from the bottom of the packet toward the top.
- • Squeeze out half (1/2) of the contents of the packet and apply it to the areas of your body shown in the diagram above (see How to use Taro-Testosterone Gel). Use a circular motion to rub in the gel for several seconds. Once you have applied this first half of the gel in the packet to your skin, squeeze out the second half and apply it in the same manner. Discard the empty packet in the household trash in a manner that prevents accidental application or ingestion by household members, especially children and breast feeding and pregnant women.
- • After opening the packet, the entire contents should be squeezed out and applied immediately onto your skin.
Usual dose:
The recommended starting dose of Taro-Testosterone Gel is 5 g (to deliver 50 mg of testosterone). This is provided by either:
- 4 pump actuations, or
- two 25 mg packets, or
- one 50 mg packet
Overdose:
If you use more Taro-Testosterone Gel than your recommended dose, wash the skin with soap and water where Taro-Testosterone Gel was applied and talk to your healthcare professional.
If someone else is exposed to Taro-Testosterone Gel either by direct contact with the gel itself or indirectly because of contact with your treated skin, that person should wash the area of contact thoroughly with soap and water as soon as possible. The longer the gel is in contact with the skin before washing, the greater is the chance that the other person will absorb some testosterone.
Missed Dose:
If you missed a dose of this medication and it is more than 12 hours until your next dose, take the dose that you missed as soon as you remember. If your next dose is less than 12 hours away skip the missed dose and continue with your next scheduled dose. Go back to the regular dosing schedule. Do not use two doses at the same time.
