Sorry, I o not know the answer to this. doxycycline however would be unlikely to turn your ejaculate dark. I doubt it is anythng of concern however. EWH
Thank you doctor, your expertise is greatly appreciated. I have 2 doxycycline tablets left to take, but have one further question. I masturdbated yesterday and noticed that my semen had a dark, almost brownish colour to it. Is this a result of the medication I have been taking?
Thank you
Welcome to our forum. I'll be happy to answer your questions. I suspect that some of your questions relate to your doctor’s comment that gonorrhea is becoming increasingly resistant to the effect of antibiotics. This is a true statement but the net effect of this increasing problem is that ceftriaxone is increasingly the preferred drug for gonorrhea treatment. When given with doxycycline (given because of the possibility of co-infection with chlamydia), the combination of drugs you took is close to 100% effective. Published studies suggest that about 3% of patients will fail therapy but most experts believe that these so-called failures actually represent re-exposure to an infected partner rather than true failure due to antibiotic resistance. I would urge you not to worry about the possibility of treatment failure.
Let's work through your questions one by one, using the same numbers you used.
1. See above. Given what you have told me, there is VERY little chance of treatment failure. It sounds like you had your infection for some time before you were treated and thus it is not too surprising that it is taking a while for your symptoms to resolve completely. In addition, I would add that most men have a small amount of normal clear discharge due to the presence of normal genital secretions which is typically overlooked and ignored unless a person is looking for it. Because of your recent diagnosis, I suspect you are more attuned to this than you normally would be. I would not worry about the slight discharge you have noted.
2. As I said above, treatment failure is most unlikely. Repeat testing will be no help until at least a week after your last dose of doxycycline. You could go for re-evaluation at that time if you wish.
3. Unlikely. the ceftriaxone would have eliminated any risk of disseminated gonorrhea. I would not worry about your knee pain as a manifestation of infection.
4. No problem with alcohol consumption. The only deleterious effect that drinking can have on doxycycline is that it can make people forget to take their medications.
Hope these comments help. I would not to worry. EWH
