Name: Acticlate

Acticlate Interactions

Do not take iron supplements, multivitamins, calcium supplements, antacids, or laxatives within 2 hours before or after taking doxycycline.

Avoid taking any other antibiotics with doxycycline unless your doctor has told you to.

Avoid exposure to sunlight or tanning beds. Doxycycline can make you sunburn more easily. Wear protective clothing and use sunscreen (SPF 30 or higher) when you are outdoors.

Antibiotic medicines can cause diarrhea, which may be a sign of a new infection. If you have diarrhea that is watery or bloody, stop taking doxycycline and call your doctor. Do not use anti-diarrhea medicine unless your doctor tells you to.

Other drugs may interact with doxycycline, including prescription and over-the-counter medicines, vitamins, and herbal products. Tell each of your health care providers about all medicines you use now and any medicine you start or stop using.

To reduce the development of drug-resistant bacteria and maintain the effectiveness of Acticlate and Acticlate CAP and other antibacterial drugs, Acticlate and Acticlate CAP should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria. When culture and susceptibility information are available, they should be considered in selecting or modifying antibacterial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy.

Nonclinical Toxicology

Carcinogenesis, Mutagenesis, Impairment of Fertility

Long-term studies in animals to evaluate carcinogenic potential of Acticlate (doxycycline hyclate) and Acticlate CAP (doxycycline hyclate) have not been conducted.
However, a 2 year carcinogenicity study with doxycycline administered daily by oral gavage to adult rats (20, 75, 200 mg/kg/day) demonstrated an increase in uterine polyps in female rats at 200 mg/kg/day (10 times the maximum recommended daily adult dose of Acticlate and Acticlate CAP based on body surface area comparison) with no change in tumor incidence in male rats at the same dose. A 2-year carcinogenicity study with doxycycline administered daily by oral gavage to adult male (maximum dose 150 mg/kg/day) and female (maximum dose 300 mg/kg/day) mice showed no changes in tumor incidence, at approximately 4 and 7 times the maximum recommended daily adult dose of Acticlate and Acticlate CAP, based on a body surface area comparison, respectively.

Mutagenesis and fertility studies have not been conducted with Acticlate and Acticlate CAP. Mutagenesis studies with doxycycline demonstrated no potential to cause genetic toxicity in an in vitro point mutation study with mammalian cells or in an in vivo micronucleus assay in CD-1 mice. However, data from an in vitro mammalian chromosomal aberration assay conducted in CHO cells suggest that doxycycline is a weak clastogen. Oral administration of doxycycline to Sprague-Dawley rats showed adverse effects on fertility and reproduction including increased time for mating, reduced sperm motility, velocity and concentration as well as increased pre and post implantation loss. Reduced sperm velocity was seen at the lowest dosage tested, 50 mg/kg/day which is 2.5 times the maximum recommended daily adult dose of Acticlate and Acticlate CAP. Although doxycycline impairs the fertility of rats when administered at sufficient dosages, the effect of Acticlate and Acticlate CAP on human fertility is unknown.

Animal Toxicology and/or Pharmacology

Hyperpigmentation of the thyroid has been produced by members of the tetracycline-class in the following species: in rats by oxytetracycline, doxycycline, tetracycline PO4, and methacycline; in minipigs by doxycycline, minocycline, tetracycline PO4, and methacycline; in dogs by doxycycline and minocycline; in monkeys by minocycline.

Minocycline, tetracycline PO4, methacycline, doxycycline, tetracycline base, oxytetracycline HCl, and tetracycline HCl, were goitrogenic in rats fed a low iodine diet. This goitrogenic effect was accompanied by high radioactive iodine uptake. Administration of minocycline also produced a large goiter with high radioiodine uptake in rats fed a relatively high iodine diet.

Treatment of various animal species with this class of drugs has also resulted in the induction of thyroid hyperplasia in the following: in rats and dogs (minocycline); in chickens (chlortetracycline); and in rats and mice (oxytetracycline). Adrenal gland hyperplasia has been observed in goats and rats treated with oxytetracycline.

Results of animal studies indicate that tetracyclines cross the placenta and are found in fetal tissues.

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.

Benign intracranial hypertension resulting in permanent loss of vision has been reported.

A 70-year-old female patient with no significant medical history suddenly developed a severe headache followed by vomiting about 15 minutes after the initial dose of this drug. The patient also experienced memory dysfunction; she could not remember the events of the afternoon prior to the dose of this drug and could not retain the information after she was reminded. The incident lasted about 30 minutes and she was transported to the hospital for further evaluation. No further cause, such as intoxication or trauma, could be elicited. Once at the hospital, the patient was able to remember the events of the afternoon and could retain new information, but amnesia regarding the events of the 30 minutes following the onset of the headache persisted. The patient's laboratory results, computerized tomography scan, MRI scan, cerebrospinal fluid, and electroencephalogram showed no pathology. When the patient was discharged 2 days later, the amnesia for the 30 minutes continued. After elimination of other symptomatic causes, the amnesia was concluded to be due to this drug because of the close relation of the dose and the onset of symptoms.[Ref]

In a double-blinded study, this drug was found to be more phototoxic than minocycline and demeclocycline. Paresthesias of the body areas exposed to sunlight may be early signs of sunburn reactions.

A case report of a possible photoallergic reaction described scaly erythema and vesicles on the face and neck associated with administration of this drug. Upon rechallenge, a flare with erythema, itching, and burning occurred in the same area.

Another case report was documented in Australian troops treated with 100 mg daily for malaria prophylaxis while on deployment in East Timor, a group of islands within the Malaysian archipelago located close to the equator. Of the 135 troops, 22 exhibited phototoxic reactions to low doses of this drug that resembled severe sunburn with erythematous plaques on the sun-exposed areas. The troops used a sunscreen containing oxybenzone.

An 11-year-old boy treated with this drug for brucellosis was evaluated for painless brown nail discoloration. This drug was initiated for brucellosis but stopped when the boy developed photosensitivity, but 15 days after the initiation of therapy brown nail discoloration developed. Other than the brown discoloration, the boy's physical condition was normal and the discoloration disappeared within 1 month.[Ref]

Doxycycline Breastfeeding Warnings

Tetracyclines have been considered contraindicated during breastfeeding due to possible staining of infants' dental enamel or bone deposition of tetracyclines; however, a close review of available literature suggests harmful effects are unlikely with short-term use of this drug during lactation as milk levels are low and infant absorption is inhibited by the calcium in breast milk. According to some experts, this drug is compatible for short courses (e.g., 10 days) if alternative therapy is not appropriate; diarrhea may occur in the nursing infant. The extent of drug absorption by breastfed infants is unknown. Short-term use in lactating women is not explicitly contraindicated by most manufacturers, but the effects of prolonged drug exposure via breast milk are unknown. Long-term or repeat courses are not recommended during nursing as a theoretical precaution. Theoretical risks of dental staining and inhibition of bone growth in nursing infants are considered unlikely by most experts. After 2 oral doses (200 mg followed by 100 mg 12 hours later) in 15 nursing mothers, milk drug levels 3 and 24 hours after dosing averaged 0.77 mg/L (range: 0.4 to 1.4 mg/L) and 0.38 mg/L (range: 0.12 to 0.85 mg/L), respectively. This drug (100 mg/day) was given orally to 10 mothers. On day 2, milk drug levels 3 and 24 hours after dosing averaged 0.82 mg/L (range: 0.37 to 1.24 mg/L) and 0.46 mg/L (range: 0.3 to 0.91 mg/L), respectively. Using peak and trough milk level averages in this study, the estimated intake of an infant only fed breast milk averaged about 6% of the maternal weight-adjusted dose. Peak milk levels averaged 0.96 mg/L after a single 100 mg dose (n=3) and 1.8 mg/L after a single 200 mg dose (n=3). After 100 mg orally twice a day for 5 days, milk drug levels were about 3.6 mg/L. In another study, in the immediate postpartum period, peak milk levels were 0.6 mg/L after oral doses of 100 mg (n=3) and averaged 1.1 mg/L after 200 mg (n=11). After a single 200 mg dose (n=2), milk levels 2, 4, and 6 hours after dosing averaged 0.8, 0.7, and 0.4 mg/L, respectively.

LactMed: Short-term use is considered acceptable; as a precaution (theoretical), prolonged or repeat courses should be avoided throughout breastfeeding. -IV: The manufacturer makes no recommendation regarding use during lactation. -Oral: According to some authorities and manufacturers, a decision should be made to discontinue breastfeeding or discontinue the drug, taking into account the importance of the drug to the mother; according to other authorities and manufacturers, use is contraindicated. Use of the 40 mg capsule formulation is not recommended. Excreted into human milk: Yes Comments: -According to at least 1 manufacturer: Developmental and health benefits of breastfeeding should be considered as well as the mother's clinical need for the drug; potential side effects in the breastfed child due to the drug or the mother's underlying condition should be considered. -The effects in the nursing infant are unknown; the infant should be monitored for rash and possible effects on the gastrointestinal flora (e.g., diarrhea or candidiasis [thrush, diaper rash]). -Tetracycline, a related drug, is considered compatible with breastfeeding by the American Academy of Pediatrics.
