ABOUT THIS MEDICATION

JAMP Dutasteride Capsules is also used with another medicine called tamsulosin, an alpha blocker, which acts by relaxing smooth muscle in the prostate and bladder neck at the site of obstruction, resulting in improvements in BPH symptoms and improved urinary flow.

WARNINGS AND PRECAUTIONS
Serious Warnings and Precautions

BEFORE you use JAMP Dutasteride Capsules, talk to your doctor or pharmacist if:
- You have or have had liver problems
- You have or have had prostate cancer or urinary tract disease.
What are the special precautions about JAMP Dutasteride Capsules?
- Do not donate blood while taking JAMP Dutasteride Capsules and for at least 6
JAMP Dutasteride Capsules in order to prevent giving dutasteride to a pregnant woman through blood transfusion.
- In a clinical study of men aged 50 to 75 years with a recent negative biopsy for prostate cancer and an increased prostate specific antigen (PSA) blood test, men taking dutasteride had a serious form of prostate cancer more often than men who did not take dutasteride.
You must see your doctor regularly. While taking JAMP Dutasteride Capsules, you must have regular checkups, including digital rectal examination and PSA examination. Follow your doctor’s advice about when to have these checkups.
Checking for prostate cancer
A man can have BPH and prostate cancer at the same time. Prior to treatment with JAMP Dutasteride Capsules, you should have a thorough urological evaluation to determine the severity of your condition, and to rule out the need for immediate surgery or the possibility of prostate cancer.
About Prostate Specific Antigen (PSA)
If a doctor asks you to have a Prostate Specific Antigen (PSA) test which is used for screening prostate cancer, you should tell your doctor that you are taking JAMP Dutasteride Capsules. JAMP Dutasteride Capsules can lower the PSA test result. A low PSA level may give you a false sense of security about your risk for prostate cancer. Your doctor is aware of this effect and can still use PSA to see if you might have prostate cancer. Increases in your PSA levels while on treatment with JAMP Dutasteride Capsules (even if the PSA levels are in the normal range) should be evaluated by your doctor.
