A 34-year-old member asked:

what are the differences between minocycline, doxycline and tetracycline?

Tetracycline: This group of antibiotics started with the discovery of tetracycline. Changing the formula of its chemical composition gave birth to the new derivatives - Minocycline and doxycycline. Bacterial coverage remains the same but dosage convenience was the result. The original tetracycline had to be taken 4x a day while the newer generation is dosed as 2x a day due to their longer duration of action.

See below: They are all 3 antibiotics of the tetracycline class and have very similar antibacterial spectrums. Minocycline and Doxycycline can be given safely to patients with renal failure. Minocycline gets high nasal and sinus levels and is good for MRSA colonization treatment. Doxycycline can cause photosensitivity but is otherwise well tolerated.

A 18-year-old member asked:

Does doxycycline have side effects?

2 doctor answers4 doctors weighed in
Dr. Robert Kwok
Pediatrics 33 years experience
Occasionally: Doxycycline is a useful antibiotic, but as with all medications, there are possible side effects. Every drug or supplement has some small risks, so a user has to weigh the benefits against the small chance of an allergic reaction or some other problem. Doxycycline is often used to treat acne in teen boys. Users can sunburn more easily. "doxy" is not used in younger kids nor in pregnant women.

Is it a bad idea to take minocin (minocycline) tablets and alcohol?

Together?: Not a good idea to wash down Minocycline with ethanol (and certainly not with methanol), but all other restrictions aside it should not interfere with the antibiotic effect of minocycline, and Minocycline will not diminish the intoxication potential of ethanol.
