Before taking mesterolone
Tillbaka till innehållSome medicines are not suitable for people with certain conditions, and sometimes a medicine may only be used if extra care is taken. For these reasons, before you start taking mesterolone it is important that your doctor knows:
Om du har lever- eller njurproblem.
If you have heart problems or high blood pressure (hypertension).
If you have epilepsy or migraine.
If you have diabetes.
If you have cancer.
Om du tar eller använder några andra läkemedel. Detta inkluderar alla läkemedel du tar som finns att köpa utan recept, samt växtbaserade och komplementära läkemedel.
Om du någonsin har haft en allergisk reaktion mot en medicin.

How to take mesterolone
Tillbaka till innehållBefore you start this treatment, read the manufacturer's printed information leaflet from inside your pack. The leaflet will give you more information about mesterolone tablets.
Take the tablets exactly as your doctor has told you to. To begin with, it is usual to be prescribed 25 mg (one tablet), to be taken three or four times a day. If you need to continue taking the tablets for more than a few months, your doctor may reduce the number of tablets you need to take each day. Your doctor will tell you what dose is right for you and this will also be printed on the label of the pack to remind you.
Swallow the tablet whole with a drink of water. You can take mesterolone before or after meals.
Försök att ta dina doser vid samma tid varje dag, eftersom det hjälper dig att komma ihåg att ta dem.
If you forget to take a dose, you should take it when you remember. However, if when you remember, it is nearly time for your next dose then leave out the forgotten dose. Do not take two doses at the same time to make up for a missed dose.
Få ut det mesta av din behandling
Tillbaka till innehållTry to keep your regular appointments with your doctor so your progress can be monitored. While you are on mesterolone your doctor will want you to have regular blood tests and examinations of your prostate and breasts. This is because the treatment may increase the rate of growth of some types of cancer and your doctor will want to rule these out. Your doctor will explain this to you before you start taking mesterolone, but if you have any concerns during your treatment, make an appointment to speak with your doctor again.
It is unlikely that mesterolone tablets will interact with any medicines you may buy, but it is always wise to check this with a pharmacist first.
The tablets are for you. Never give them to other people, even if their condition appears to be the same as yours. The tablets are not suitable for increasing muscle strength and bodybuilding in healthy men and should not be taken for this reason.
