What is Proviron used for
Proviron balances a deficiency of male sex hormones (androgen) formation, which begin to fall gradually with increasing age. Proviron is used to treat a condition called hypogonadism. It does this by replacing the body’s natural hormone testosterone when not enough is made by the body.
Testosterone is a natural male hormone, known as an androgen, which controls normal sexual development in men. Testosterone is essential for the development and maintenance of the male reproductive organs as well as other male characteristics, such as deep voice, increased muscle strength, hair growth etc.
Proviron is available by prescription only. Proviron is not addictive.
Proviron is for use in male patients only.

How to take Proviron
How much to take
Your doctor or pharmacist will tell you how much and how often you should take Proviron. For Proviron to work best it is very important to take Proviron exactly as your doctor tells you. You should not exceed the recommended dose your doctor has prescribed for you.
How to take it
Swallow the tablet whole with a glass of water or other fluid. Do not chew the tablets.
When to take it
Generally initial treatment consists of 1-2 tablets three times per day which may be reduced after some months.
If you forget to take it
If it is almost time for your next dose, skip the dose you missed and take your next dose when you are meant to. Otherwise, take it as soon as you remember, and then go back to taking it as you would normally. Do not take a double dose to make up for the dose that you missed. If you are not sure what to do, ask your doctor or pharmacist. If you have trouble remembering when to take your medicine, ask your pharmacist for some hints.
If you take too much (overdose)
Immediately telephone your doctor, or the Poisons Information Centre, or go to the accident and emergency department at your nearest hospital, if you think you or anyone else may have taken too much Proviron. Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.
While you are using Proviron
Your doctor will conduct regular examinations of the prostate. In rare cases non-cancerous and in even rarer cases cancerous liver tumours leading in isolated cases to life-threatening bleeding within the stomach have been observed after the use of hormonal substances such as the one contained in Proviron. Tell your doctor if you have any unusual abdominal complaints which do not disappear within a short time.
Do not give your Proviron tablets to anyone else, even if they have the same condition as you.
Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking Proviron.
