⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS The use of drugs of the tetracycline-class during tooth development (last half of pregnancy, infancy and childhood to the age of 8 years) may cause permanent discoloration of the teeth (yellow-gray-brown). ( 2.2 , 5.1 ) Clostridium difficile -associated diarrhea (CDAD) has been reported. Evaluate patients if diarrhea occurs.
( 5.2 ) Photosensitivity manifested by an exaggerated sunburn reaction has been observed in some individuals taking tetracyclines. Limit sun exposure. ( 5.3 ) Overgrowth of non-susceptible organisms, including fungi, may occur.
If such infections occur, discontinue use and institute appropriate therapy. ( 5.4 )
5.1Tooth Development The use of drugs of the tetracycline-class during tooth development (last half of pregnancy, infancy and childhood to the age of 8 years) may cause permanent discoloration of the teeth (yellow-gray-brown). This adverse reaction is more common during long-term use of the drugs but it has been observed following repeated short-term courses. Enamel hypoplasia has also been reported.
Use ACTICLATE and ACTICLATE CAP in pediatric patients 8 years of age or less only when the potential benefits are expected to outweigh the risks in severe or life-threatening conditions (e.g., anthrax, Rocky Mountain spotted fever), particularly when there are no alternative therapies.
5.2Clostridium difficile Associated Diarrhea Clostridium difficile associated diarrhea (CDAD) has been reported with use of nearly all antibacterial agents, including ACTICLATE and ACTICLATE CAP, and may range in severity from mild diarrhea to fatal colitis. Treatment with antibacterial agents alters the normal flora of the colon leading to overgrowth of C. difficile . C. difficile produces toxins A and B which contribute to the development of CDAD.
Hypertoxin producing strains of C. difficile cause increased morbidity and mortality, as these infections can be refractory to antibacterial therapy and may require colectomy. CDAD must be considered in all patients who present with diarrhea following antibacterial use. Careful medical history is necessary since CDAD has been reported to occur over two months after the administration of antibacterial agents.
If CDAD is suspected or confirmed, ongoing antibacterial use not directed against C. difficile may need to be discontinued. Appropriate fluid and electrolyte management, protein supplementation, antibacterial treatment of C. difficile , and surgical evaluation should be instituted as clinically indicated.
5.3Photosensitivity Photosensitivity manifested by an exaggerated sunburn reaction has been observed in some individuals taking tetracyclines. Patients apt to be exposed to direct sunlight or ultraviolet light should be advised that this reaction can occur with tetracycline drugs, and treatment should be discontinued at the first evidence of skin erythema.
5.4Potential for Microbial Overgrowth ACTICLATE and ACTICLATE CAP may result in overgrowth of non-susceptible organisms, including fungi. If such infections occur, discontinue use and institute appropriate therapy.
5.5Severe Skin Reactions Severe skin reactions, such as exfoliative dermatitis, erythema multiforme, Stevens-Johnson syndrome, toxic epidermal necrolysis, and drug reaction with eosinophilia and systemic symptoms (DRESS) have been reported in patients receiving doxycycline [See Adverse Reactions ( 6 ) ]. If severe skin reactions occur, doxycycline should be discontinued immediately and appropriate therapy should be instituted.
5.6Intracranial Hypertension Intracranial hypertension (IH, pseudotumor cerebri) has been associated with the use of tetracyclines including ACTICLATE and ACTICLATE CAP. Clinical manifestations of IH include headache, blurred vision, diplopia, and vision loss; papilledema can be found on fundoscopy. Women of childbearing age who are overweight or have a history of IH are at greater risk for developing tetracycline associated IH. Concomitant use of isotre…
🤒 Adverse Reactions ▾
6 ADVERSE REACTIONS The following adverse reactions have been identified during clinical trials or post-approval use of tetracycline-class drugs, including doxycycline. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Gastrointestinal: Anorexia, nausea, vomiting, diarrhea, glossitis, dysphagia, enterocolitis, and inflammatory lesions (with monilial overgrowth) in the anogenital region, and pancreatitis.
Hepatotoxicity has been reported. These reactions have been caused by both the oral and parenteral administration of tetracyclines. Superficial discoloration of the adult permanent dentition, reversible upon drug discontinuation and professional dental cleaning has been reported.
Permanent tooth discoloration and enamel hypoplasia may occur with drugs of the tetracycline class when used during tooth development [ See Warnings and Precautions ( 5.1 ) ]. Instances of esophagitis and esophageal ulcerations have been reported in patients receiving capsule and tablet forms of drugs in the tetracycline-class. Most of these patients took medications immediately before going to bed [see Dosage and Administration ( 2.1 )].
Skin: Maculopapular and erythematous rashes, Stevens-Johnson syndrome, toxic epidermal necrolysis, exfoliative dermatitis, and erythema multiforme have been reported. Photosensitivity has been reported [see Warnings and Precautions ( 5.3 )]. Renal: Rise in BUN has been reported and is apparently dose-related [see Warnings and Precautions ( 5.8 )].
Hypersensitivity reactions: Urticaria, angioneurotic edema, anaphylaxis, anaphylactoid purpura, serum sickness, pericarditis, and exacerbation of systemic lupus erythematosus, and drug reaction with eosinophilia and systemic symptoms (DRESS). Blood: Hemolytic anemia, thrombocytopenia, neutropenia, and eosinophilia have been reported. Intracranial Hypertension: Intracranial hypertension (IH, pseudotumor cerebri) has been associated with the use of tetracyclines [see Warnings and Precautions ( 5.6 )].
Thyroid Gland Changes: When given over prolonged periods, tetracyclines have been reported to produce brown-black microscopic discoloration of thyroid glands. No abnormalities of thyroid function are known to occur. Adverse reactions observed in patients receiving tetracyclines include anorexia, nausea, vomiting, diarrhea, rash, photosensitivity, urticaria, and hemolytic anemia.

🔄 Drug Interactions ▾
7 DRUG INTERACTIONS Patients who are on anticoagulant therapy may require downward adjustment of their anticoagulant dosage. ( 7.1 ) Avoid co-administration of tetracyclines with penicillin. ( 7.2 ) Absorption of tetracyclines, including ACTICLATE and ACTICLATE CAP is impaired by antacids containing aluminum, calcium, or magnesium, bismuth subsalicylate and iron-containing preparations.
( 7.3 ) Concurrent use of tetracyclines, including ACTICLATE and ACTICLATE CAP may render oral contraceptives less effective. ( 7.4 ) Barbiturates, carbamazepine and phenytoin decrease the half-life of doxycycline. ( 7.5 )
7.1Anticoagulant Drugs Because tetracyclines have been shown to depress plasma prothrombin activity, patients who are on anticoagulant therapy may require downward adjustment of their anticoagulant dosage.
7.2Penicillin Since bacteriostatic drugs may interfere with the bactericidal action of penicillin, it is advisable to avoid giving tetracyclines, including ACTICLATE and ACTICLATE CAP in conjunction with penicillin.
7.3Antacids and Iron Preparations Absorption of tetracyclines, including ACTICLATE and ACTICLATE CAP is impaired by antacids containing aluminum, calcium, or magnesium, bismuth subsalicylate, and iron-containing preparations.
7.4Oral Contraceptives Concurrent use of tetracyclines, including ACTICLATE and ACTICLATE CAP may render oral contraceptives less effective.
7.5Barbiturates and Anti-Epileptics Barbiturates, carbamazepine, and phenytoin decrease the half-life of doxycycline.
7.6Penthrane ® The concurrent use of tetracycline and Penthrane ® (methoxyflurane) has been reported to result in fatal renal toxicity.
7.7Drug and Laboratory Test Interactions False elevations of urinary catecholamines may occur due to interference with the fluorescence test.
👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS Tetracycline-class drugs can cause fetal harm when administered to a pregnant woman, but data for doxycycline are limited. ( 5.6 , 8.1 ) Tetracyclines are excreted in human milk; however, the extent of absorption of doxycycline in the breastfed infant is not known. ACTICLATE and ACTICLATE CAP use during nursing should be avoided if possible. ( 8.3 )
8.1Pregnancy Teratogenic Effects. Pregnancy Category D: [see Warnings and Precautions ( 5.7 )] There are no adequate and well-controlled studies on the use of doxycycline in pregnant women. The vast majority of reported experience with doxycycline during human pregnancy is short-term, first trimester exposure.
There are no human data available to assess the effects of long-term therapy of doxycycline in pregnant women such as that proposed for the treatment of anthrax exposure. An expert review of published data on experiences with doxycycline use during pregnancy by TERIS - the Teratogen Information System - concluded that therapeutic doses during pregnancy are unlikely to pose a substantial teratogenic risk (the quantity and quality of data were assessed as limited to fair), but the data are insufficient to state that there is no risk.
1 A case-control study (18,515 mothers of infants with congenital anomalies and 32,804 mothers of infants with no congenital anomalies) shows a weak but marginally statistically significant association with total malformations and use of doxycycline anytime during pregnancy. Sixty-three (0.19%) of the controls and 56 (0.30%) of the cases were treated with doxycycline. This association was not seen when the analysis was confined to maternal treatment during the period of organogenesis (that is, in the second and third months of gestation), with the exception of a marginal relationship with neural tube defect based on only two-exposed cases.
2 A small prospective study of 81 pregnancies describes 43 pregnant women treated for 10 days with doxycycline during early first trimester. All mothers reported their exposed infants were normal at 1 year of age. 3 Nonteratogenic effects: [see Warnings and Precautions ( 5.1 , 5.7 )].
8.3Nursing Mothers Tetracyclines are excreted in human milk, however, the extent of absorption of tetracyclines including doxycycline, by the breastfed infant is not known. Short-term use by lactating women is not necessarily contraindicated. The effects of prolonged exposure to doxycycline in breast milk are unknown 4 .
Because of the potential for serious adverse reactions in nursing infants from doxycycline, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother [see Warnings and Precautions ( 5.1 , 5.7 )].
8.4Pediatric Use Because of the effects of drugs of the tetracycline-class on tooth development and growth, use ACTICLATE and ACTICLATE CAP in pediatric patients 8 years of age or less only when the potential benefits are expected to outweigh the risks in severe or life-threatening conditions (e.g., anthrax, Rocky Mountain spotted fever), particularly when there are no alternative therapies [see Warnings and Precautions ( 5.1 , 5.7 ) and Dosage and Administration ( 2.1 , 2.5 )] .
8.5Geriatric Use Clinical studies of doxycycline hyclate tablets did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. ACTICLATE Tablets each contains less than 1 mg of sodium.

Other reported clinical experience has not identified differences in responses between the elderly and younger patients. ACTICLATE Tablets each contains less than 1 mg of sodium.
🆘 Overdosage ▾
10 OVERDOSAGE In case of overdosage, discontinue medication, treat symptomatically and institute supportive measures. Dialysis does not alter serum half-life and thus would not be of benefit in treating cases of overdosage.
🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action Doxycycline is a tetracycline-class antimicrobial drug [see Microbiology ( 12.4 )] .
12.3Pharmacokinetics Absorption ACTICLATE (doxycycline hyclate) Tablets: Following administration of a single 300 mg dose to adult volunteers, average peak plasma doxycycline levels were 3.0 mcg per mL at 3 hours, decreasing to 1.18 mcg per mL at 24 hours. The mean C max and AUC 0-∞ of doxycycline are 24% and 15% lower, respectively, following single dose administration of ACTICLATE, 150 mg tablets with a high fat meal (including milk) compared to fasted conditions. The clinical significance of these decreases is unknown.
ACTICLATE CAP (doxycycline hyclate) Capsules. Following administration of a single 300 mg dose to adult volunteers, average peak plasma doxycycline levels were 2.8 mcg per mL at 3 hours, decreasing to 1.1 mcg per mL at 24 hours. The mean C max of doxycycline is approximately 20% lower and the AUC 0-∞ is unchanged following single dose administration of ACTICLATE CAP Capsules with a high fat meal (including milk) compared to fasted conditions.
The clinical significance of this decrease in C max is unknown. Excretion Tetracyclines are concentrated in bile by the liver and excreted in the urine and feces at high concentrations and in a biologically active form. Excretion of doxycycline by the kidney is about 40% per 72 hours in individuals with a creatinine clearance of about 75 mL per minute.
This percentage may fall as low as 1% per 72 hours to 5% per 72 hours in individuals with a creatinine clearance below 10 mL per minute. Studies have shown no significant difference in the serum half-life of doxycycline (range 18 to 22 hours) in individuals with normal and severely impaired renal function. Hemodialysis does not alter the serum half-life.
12.4Microbiology Mechanism of Action Doxycycline inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit. Doxycycline has bacteriostatic activity against a broad range of Gram-positive and Gram-negative bacteria. Resistance Cross resistance with other tetracyclines is common.
Antimicrobial Activity Doxycycline has been shown to be active against most isolates of the following microorganisms, both in vitro and in clinical infections [see Indications and Usage ( 1 )] . Gram-negative bacteria Acinetobacter species Bartonella bacilliformis Brucella species Campylobacter fetus Enterobacter aerogenes Escherichia coli Francisella tularensis Haemophilus ducreyi Haemophilus influenzae Klebsiella granulomatis Klebsiella species Neisseria gonorrhoeae Shigella species Vibrio cholerae Yersinia pestis Gram-positive bacteria Bacillus anthracis Listeria monocytogenes Streptococcus pneumoniae Anaerobic bacteria Clostridium species Fusobacterium fusiforme Propionibacterium acnes Other bacteria Nocardiae and other aerobic Actinomyces species Borrelia recurrentis Chlamydophila psittaci Chlamydia trachomatis Mycoplasma pneumoniae Rickettsiae species Treponema pallidum Treponema pallidum subspecies pertenue Ureaplasma urealyticum Parasites Balantidium coli Entamoeba species Plasmodium falciparum* *Doxycycline has been found to be active against the asexual erythrocytic forms of Plasmodium falciparum , but not against the gametocytes of P. falciparum .
The precise mechanism of action of the drug is not known. Susceptibility Testing Methods When available, the clinical microbiology laboratory should provide cumulative reports of in vitro susceptibility test results for antimicrobial drugs used in local hospitals and practice as periodic reports that describe the susceptibility profile of nosocomial and community-acquired pathogens. These reports should aid in the selection of an appropriate antibacterial drug for treatment.
Dilution techniques: Quantitative methods are used to determine antimicrobial minimum inhibitory concentrations (MICs). These MICs provide estimates of the susceptibility of bacteria to antimicrobial compounds. The MICs v…

💬 Information for Patients ▾
17 PATIENT COUNSELING INFORMATION Advise the patient to read the FDA-approved patient labeling ( Instructions for Use ). Advise patients taking ACTICLATE and ACTICLATE CAP for malaria prophylaxis: that no present-day antimalarial agent, including doxycycline, guarantees protection against malaria. to avoid being bitten by mosquitoes by using personal protective measures that help avoid contact with mosquitoes, especially from dusk to dawn (for example, staying in well-screened areas, using mosquito nets, covering the body with clothing, and using an effective insect repellent). that doxycycline prophylaxis: - should begin 1 day to 2 days before travel to the malarious area, - should be continued daily while in the malarious area and after leaving the malarious area, - should be continued for 4 further weeks to avoid development of malaria after returning from an endemic area, - should not exceed 4 months.
Advise all patients taking ACTICLATE and ACTICLATE CAP: that ACTICLATE Tablets (150 mg) can be broken into two-thirds or one-third at the scored lines to provide 100 mg or 50 mg strength doses, respectively. that they must swallow ACTICLATE CAP whole. They must not break, open, crush, dissolve or chew the capsule [ see Dosage and Administration ( 2.2 ) ]. to avoid excessive sunlight or artificial ultraviolet light while receiving doxycycline and to discontinue therapy if phototoxicity (for example, skin eruptions, etc.) occurs.
Sunscreen or sunblock should be considered [see Warnings and Precautions ( 5.3 )] . to drink fluids liberally along with ACTICLATE and ACTICLATE CAP to reduce the risk of esophageal irritation and ulceration [see Adverse Reactions ( 6 )] . that the absorption of tetracyclines is reduced when taken with foods, especially those that contain calcium [see Drug Interactions ( 7.3 )] . However, the absorption of doxycycline is not markedly influenced by simultaneous ingestion of food or milk [see Clinical Pharmacology ( 12.3 )] . that if gastric irritation occurs, ACTICLATE and ACTICLATE CAP may be given with food or milk [see Clinical Pharmacology ( 12.3 )] . that the absorption of tetracyclines is reduced when taken with antacids containing aluminum, calcium or magnesium, bismuth subsalicylate, and iron-containing preparations [see Drug Interactions ( 7.3 )] . that the use of doxycycline might increase the incidence of vaginal candidiasis.
Advise patients that diarrhea is a common problem caused by antibacterial drugs which usually ends when the antibacterial is discontinued. Sometimes after starting treatment with antibacterial drugs, patients can develop watery and bloody stools (with or without stomach cramps and fever) even as late as two or more months after having taken the last dose of antibacterial. If this occurs, patients should contact their physician as soon as possible.
Counsel patients that antibacterial drugs including ACTICLATE and ACTICLATE CAP should only be used to treat bacterial infections. They do not treat viral infections (for example, the common cold). When ACTICLATE and ACTICLATE CAP are prescribed to treat a bacterial infection, patients should be told that although it is common to feel better early in the course of therapy, the medication should be taken exactly as directed.
Skipping doses or not completing the full course of therapy may (1) decrease the effectiveness of the immediate treatment and (2) increase the likelihood that bacteria will develop resistance and will not be treatable by ACTICLATE and ACTICLATE CAP or other antibacterial drugs in the future.
