A couple of weeks; if you have been on it longer than 3 weeks then you have a very bad case because it can take 6-8 weeks for it to become effective. If you have noticed an increase in your acne then you need to contact your doctor; you may be suffering an allergic reaction.
According to Med Help: http://www.medhelp.org/forums/Dermatology/messages/32787.html
"This drug is a reasonable choice, but if any treatment hasn't worked in 2-3 months, it's time to try something else."
According to: http://www.acneway.com/doryx_acne_side_effects.html
"For controlling acne, Doryx is normally taken over a period of 12 weeks.
If you do not complete the full course prescribed by your doctor, the infection may not clear completely or your symptoms may return.
For treating infections, Doryx is usually taken for one to two weeks"
According to: http://www.aafp.org/afp/20040501/2123.html
"Oral Antibiotics. When acne is resistant to topical therapies, oral antibiotics may be used. Oral antibiotics commonly are initial therapy in patients with moderate to severe inflammatory acne. Systemic antibiotics decrease P. acnes colonization and have intrinsic anti-inflammatory effects. First-line oral antibiotics have included tetracycline and erythromycin. Because P. acnes resistance to erythromycin is increasing, this antibiotic is becoming a second-line agent that is used when treatment with tetracycline or other macrolide antibiotics fails or is not tolerated.20
Tetracycline must be taken on an empty stomach. Iron supplements and milk products decrease systemic absorption of the antibiotic. Because of the risk of tooth discoloration and inhibited skeletal growth, tetracycline should not be used in pregnant women or children younger than nine years. Moderate to severe phototoxicity and gastrointestinal intolerance also may limit the use of tetracycline.
Doxycycline (e.g., Vibramycin, Doryx) frequently is used to treat moderate to severe acne vulgaris. However, associated photosensitivity may limit its usefulness.
Minocycline (Minocin) is a potent acne medication, but treatment with this antibiotic generally is reserved for patients who do not respond to or cannot tolerate aforementioned treatment options.21 Rare but serious side effects are more common in patients taking minocycline than in patients treated with tetracycline or doxycycline.22
Oral antibiotics must be taken for six to eight weeks before results are evident, and treatment should be given for six months to prevent the development of microbial resistance.23 Oral antibiotics may be discontinued after inflammation has resolved. Topical antibiotics may be continued for further treatment. Some patients may require long-term oral antibiotic therapy to control their acne and prevent scarring. The dosing, approximate cost, and side effects of systemic medication for the treatment of acne are summarized in Table 3."
Hopefully your doctor warned you about the associated photosensitivity, which means you need to avoid the sun. This can limit the use of the medication.
Photosensitivity means that exposure to UV light can be painful or you can sunburn easily. If you notice any of these effects then you need to contact your doctor.
According to Wikipedia: http://en.wikipedia.org/wiki/Photosensitivity
"People that are photosensitive experience discomfort or get easily sunburned when exposed to UV light, which may come from sunlight or other sources including sunbeds. This is often caused by an allergy or a medication."

NATURAL ACNE PROTOCOL
1/ Never, ever touch your face.
2/ Use 3 facecloths to wash your face, one to soap on, one to soap off with very hot water, one to rinse off with ice cold water, in that order, once a day.
3/ If you are under 18 take 5,000 IU of vitamin A once a day with a full meal
4/ If you are over 18 take 5,000 IU of vitamin A twice a day with a full meal.
Do not get pregnant while taking vitamin A. Do not take any more, like Accutane, it will stop you growing.
5/ Never, ever. pick, squeeze or pop your spot. Read number 1 again.
6/ Do this for 90 days.
7/ Invest in a brand new pillow and 2 new or more pillow cases to �double bag' your pillow. HOT wash every couple of days.
Source:
A bit of advice given to me as a teenager, a bit of science as I am studying allergic reactions and vitamin A is a part of that. A bit of research: I sat in a lecture at the back and watched the acne prone pick at their faces, those with the worse acne touched their faces 32 times in an hour, the clearest complexions didn't touch their faces even once. I have circumstantial evidence that acne is the result of dermatophyte transfer from hands to face...where it does not get washed off and is well fed by hormones, sweat a
nd oil...just a hypothesis... But it would explain why vitamin A is so effective as vitamin causes skin to remove dermatophytes.
The secret is never to touch the spots
Tips on how to treat acne and achieve perfect clear skin in as little as 7 days?

Most medications used to treat acne take 3-6 weeks before you start noticing results. Your body has to build up a consistant level. Make sure to take the medication every day exactly as prescribed. Missing doses will just delay your results. And yes, a lot of times acne gets worse before better with a new treatment. Hang in there.

Is doryx the only thing you're taking? My dermatologist prescribed Doryx , along with two topical creams: retina micro a & duac. I've been on it for a month now and my skin is noticeably different ( my acne are actually gone, i just have dark spots on my skin). I didn't notice the reasult until 2.5- 3 weeks... hope your skin will clear up soon! p.s. now to think of it, i'm not sure if thats the main reason my skin cleared up..when i start using the medications mentioned above, i've also drink alot more water, eat alot of fresh tomatoes, and applying fresh aloe vera (in place of lotion) on my skin...

I 've looked under all the tetrocycline type antibiodics, & it doesnt tell how long, it tells, may reduce after improvement.
it's got to get into the blood steam & stay there to do it's work, so just hang in there.
(take good care of your teeth at this time, the tetraclyclines can change the teeth yellow, if not taken really good care of over long periods of time). most people it does take a while. like month or months.
