Question: Currently I am taking Propecia and supplements for bodybuilding which increase testosterone levels. My understanding is that Propcia is a finasteride which is an inhibitor to the conversion of testosterone into DHT. Am I counteracting the effects of the Propecia with supplements that increase testosterone or is Propecia a specific enough inhibitor to sort out the type of testosterone created by the supplements?

Answer: Maybe, but you wil just have to watch and see. I would really avoid supplemental testerone if you are losing hair.

Question: Are there any studies on a maintenance level of Propecia, once
a satisfactory coverage of hair has been established. I have
taken the suggested dosage of Propecia (one a day) for the past
year and now my dermatologist wants me to go to one every other
day. I don't want to lose hair again. He further suggested tha
I later try one tablet every third day. Are there studies to
support this? What would be his reasoning? I have had no
side effects that I have been aware of. I am 20 years old.
Thanks. E-mail response, please.

Answer: I'd check with the company. I'm not aware of any. Merck 800-672-6372

Question: I've been being treated for migraine/tension headaches for 5 years now. I have been taking Esgic Plus for these headaches, which are daily. Additionally, I take Inderal 160mg and Neurontin 300mg (4 times daily). My Neurologist has changed the Esgic Plus to Ultram 50mg (up to 3 times daily) just this past week and it appears to be working well. In addition to these medications for headache treatment, I just started taking Propecia for hair loss. At 37 years of age, I've noticed a decrease in ability to maintain an erection. Although I understand this is a side effect of the Propecia, could the Inderal (and/or other meds.) add to this effect? Also, the Neurontin seemed to work well the first 3 months at 900mg/day. All at once, it seemed to stop working. My dr. has bumped it up to 1200mg/day, still with no benefit. Any suggestions?

Answer: Certainly can be the Inderal-also occasionally the Propecia. Ultram is a semi-synthetic narcotic and can also do this-plus is addicting. Try to minimize the medications for a time and see if it is one med or the combo.

Propecia and Hair Loss [posted 7/22/98]
Question: Does propecia cause peripheral and facial hair loss?

Answer: Propecia has been around a while in a drug called Proscar. Now, it is being relabeled as a possible way for some men to grow hair. Hair loss is not listed as a problem in the PDR and I haven't seen it with my patients taking the drug.
