- pale poo with dark pee, yellow skin or the whites of your eyes go yellow - this could be a sign of liver problems
- joint or muscle pain that has started since you began taking Doxylag
- severe headaches, vomiting and problems with your vision - these could be signs of pressure around your brain (intracranial hypertension)
- a fingernail coming away from its base - this could be a reaction to sunlight called photo-onycholysis
- a sore or swollen mouth, lips or tongue
- severe pain in your stomach, with or without bloody diarrhoea, nausea and vomiting - these can be signs of pancreatitis

4. How and when to take it
Your dose of Doxylag depends on why you are taking it.
The usual dose is 100mg to 200mg once or twice a day. If you're taking Doxylag more than once a day, try to space your doses evenly throughout the day. If you take it twice a day, this could be first thing in the morning, and in the evening.
For preventing malaria, you'll take 100mg once a day, usually in the morning. You should start taking Doxylag 1 or 2 days before going to an area where there is malaria. Carry on for 4 weeks after leaving the area. Check with your doctor or pharmacist that Doxylag is the best medicine to prevent malaria in the country you are travelling to.
Rated Doxylag (Oracea, Doryx) for Acne Report
I normally don’t give reviews on medication but I had such a horrible experience with this that I felt I should share. The first time I was prescribed Doxylag it was for dermatitis. I took 100mg twice a day and was supposed to take it for 30 days. I stopped after 14. I had severe anxiety while taking this, I was feeling really depressed to the point where I couldn’t stand to take it any longer. Not to mention the nausea, headaches, and loss of appetite. I’m taking 100mg twice per day again to prevent infection after surgery. I am on day 4 of 7 and have been waking up with severe anxiety and panic attacks. I’ve never had such terrible side effects from a medication.
Rated Doxylag (Oracea, Doryx) for Sinusitis Report
After 6 hours of taking my second 100 mg dose of this antibiotic to treat my sinus infection, I started experiencing very bad nausea, stomach burning, heart palpitations, headache, diarrhea and severe vomiting. I did drink water, ate small meals and was sitting up when I took my doses. Unfortunately, I was throwing up uncontrollably and had diarrhea and a very bad headache and had to go to ER by ambulance because I was so sick. At the ER, I was treated with nausea meds, IV and was told to stop taking this medicine. Still taking nausea meds and I have been off the drug almost 5 hours. Be very careful when taking this drug. This is the first time I’ve been this physically sick when taking a antibiotic. I will never take again. Very scary!
Rated Doxylag (Oracea, Doryx) for Chlamydia Infection Report
More a question. I take nicotinelle lozenges 2 mg.(about 15 a day to stop smoking)which contain magnesium stearate. Am worried this may impact the effectiveness of Doxylag. Can't find an answer to this anywhere. Does anybody know?
Outcome and Management
Recovery after withdrawal of Doxylag is usually rapid, but in instances with severe cholestasis, can require 2 to 6 months. No case of acute liver failure has been reported due to Doxylag, but rare instances of vanishing bile duct syndrome have been linked to its use. Cross sensitivity to hepatic injury between minocycline and Doxylag has not been shown, but both can cause a short incubation period acute hepatitis with immunoallergic features, so that some degree of cross reactivity may occur.
See also Side Effects section.
Before taking Doxylag, tell your doctor or pharmacist if you are allergic to it; or to other tetracyclines (such as minocycline); or if you have any other allergies.

Which drugs or supplements interact with Doxylag?
- It is recommended that Doxylag not be taken at the same time as aluminum, magnesium, or calcium based antacids, such as Mylanta, Maalox, Tums, or Rolaids because, like food, these medications bind Doxylag in the intestine and prevent its absorption. Similarly, Doxylag should not be taken with minerals (such as calcium or iron) or with bismuth subsalicylate (Pepto Bismol).
- Doxylag may enhance the activity of warfarin (Jantoven, Coumadin) and cause excessive "thinning" of the blood leading to exaggerated bleeding, necessitating a reduction in the dose of warfarin. Phenytoin (Dilantin), carbamazepine (Tegretol), and barbiturates (such as phenobarbital) may enhance the metabolism (destruction) of Doxylag thus making it less effective.
- Doxylag may interfere with the action of penicillins and should not be combined with penicillins. It may also reduce the effect of oral contraceptives. Combining tetracycline and methoxyflurane (Penthrane) may reduce kidney function.

Side effects of Doxylag in dogs are fairly rare. Most adult dogs tolerate the drug well.
The most common side effects in dogs include nausea, vomiting, or difficulty swallowing or breathing.
Nausea can be reduced if the medication is given to the dog with food. Swallowing or breathing problems can be reduced by following the tablet up with a small amount of water.
If gastrointestinal problems become severe, then you should contact your veterinarian, as this can be a sign of Doxylag overdose.
Doxylag can cause limb deformities in puppies still in the womb, which is also risky for pregnant mother dogs. Sometimes a veterinarian will decide that the benefits outweigh the risks of the antibiotic.
Doxylag can also interact poorly with other drugs, so make sure your vet is aware of any other medications your pet is taking.
As with almost all medications, there is a risk of allergic reaction that can lead to anaphylaxis. If you see signs of an allergic reaction, then you should contact your veterinarian immediately.

My pneumonia was improved after 9 days on a different meds, but the doctor prescribed this antibiotic to make sure all bacterial is gone to prevent relapse. Right after taking the first pill l started having a very irritated throat that made me cough a lot and it got worst day of day. My right throat, nostril, and right ear all were irritated. Nauseous and mild stomach cramps from time to time. Felt like vomit a few times after meals. My nose kept producing thick yellow mucus. Woke up with panic attacks and felt depressed for no reasons. My hands would shake often like anxiety attack. l also felt random chills through out the day and. It wasn’t day 5th that l went to doctor and wanted to find out what’s wrong with me. l stopped at day 5th and immediately felt better.
