DEAR DR. GOTT: I am a female who used Timoptic eye drops for glaucoma about 20 years ago. The beta blocker caused me many side effects, most of which went away when I discontinued the medicine. However, I still have shortness of breath and difficult urination. Is there anything that can be done to relieve these side effects?

DEAR READER: Even today, Timoptic is contraindicated for patients with a history of chronic bronchitis, emphysema, bronchial asthma, chronic obstructive pulmonary disease and a number of cardiac conditions. I cannot tie in your shortness of breath 20 years following usage, but I wonder whether you had an existing condition even then that might have been exacerbated by the medication. This can best be determined by a pulmonologist, who will listen to your lungs, and perhaps order a chest X-ray, CT or MRI to determine just what is and isn't going on.I am unaware of a link to urinary difficulties with Timoptic but can offer some other possible causes for the condition. Retention can be caused by an obstruction in the urinary tract or by mixed signals between the bladder and the brain. Diabetes, pelvic injury, vaginal childbirth, bladder stones and infection of the spinal cord are but a few more options. An infection can cause inflammation and irritation, resulting in urinary retention.A cystocele can result when the wall between the bladder and the vagina weakens, allowing the bladder to sag into the vagina. A rectocele occurs when the rectum sags into the back wall of the vagina. Both conditions can force the bladder out of position, causing incontinence and retention.I feel you need a referral to an urologist for a complete examination to rule out specific conditions, while allowing concentration on others. Unless your specialist discovers something unexpected, the issue may be controlled completely by medication. Should surgical correction be necessary, you can then discuss the pros and cons of such a procedure to determine whether it is appropriate for you. Also, he or she might have an idea whether the Timoptic may have caused the condition, or whether other circumstances came into play at the same time as your breathing difficulties.To provide related information, I am sending you copies of my Health Reports "Pulmonary Disease" and "Vaginal Infections and Disorders."

I've been to a dermatologist and was told I may have female-pattern baldness. I feel they say this because they don't know the real cause.I've had hormone testing that was OK. Can you help me to find the right shampoo to help my hair? On the Internet, they claim Provillus is the best product, but this comes with pills and a topical serum that make me leery.

DEAR READER: Healthy hair grows about a 1/2 inch each month for up to about six years. It then ultimately falls out, and a new one grows in its place. With baldness, that new hair doesn't grow back, and baldness occurs. This may be a part of the aging process, a family history of baldness or changes in the levels of hormones. Other possibilities include specific skin disorders that scar hair follicles, an iron or biotin deficiency, or medications such as beta blockers, ibuprofen, Coumadin and others.The only medication approved by the Food and Drug Administration to treat female-pattern baldness is minoxidil. Unfortunately, the treatment is expensive, and hair loss will begin again when it is discontinued. Speak with your physician regarding this possibility.
