Five questions for your doctor before a prostate supplement
The Prostacor label says to ask first. What to ask, and why each question matters.
Why the label sends you to a doctor
Prostacor's caution names two groups who should ask first: people with a medical condition and people on prescription medication. Among men old enough to shop for prostate capsules, that covers a great many.
The Food and Drug Administration gives the same advice to everyone.
FDA advises consumers to talk to their doctor, pharmacist, or other health care professional before deciding to purchase or use a dietary supplement.
1. What else the symptoms could be
Urinary trouble has more than one cause. The federal kidney and urology institute describes the gland in two plain sentences, and its position explains why problems there show up as urinary problems.
A doctor can tell an enlarged prostate from an infection or something that needs treatment soon. A capsule cannot.
The prostate is a walnut-shaped gland that is part of a man's sex organs, which also include the penis, scrotum, and testicles.
The prostate is in front of the rectum and just below the bladder.
2. What it may interact with
Bring the bottle, or a photo of its panel. The five ingredients and the 351 mg total are what your doctor or pharmacist needs to see.
The supplements office at the NIH puts the risk in one line.
Supplements can also interact with some medicines in ways that might cause problems.
Tell your health care providers (including doctors, dentists, pharmacists, and dietitians) about any dietary supplements you're taking.
3. One capsule or two
The label allows either: one capsule once or twice daily. It also says "or as directed by a physician", which hands the decision to your doctor.
The NIH makes the same point about every supplement.
The manufacturer suggests the serving size, but your health care provider might decide a different amount is more appropriate for you.
4. What not to stop on your own
Do not drop a prescription on your own because you started a supplement. The label says the capsules are not intended to treat any disease.
The federal advice is direct.
Get your health care provider's approval before taking dietary supplements in place of, or in combination with, prescribed medicines.
5. When to come back
Ask what change would mean the capsules are not enough, and how soon to return. Agree on a date before you buy a second bottle: at one capsule a day the first runs out in 30 days.
One symptom should never wait for an appointment.
If you can't urinate at all, you should get medical help right away.
