Doxycycline - Summary

Doxycycline medication is used to treat a wide range of infectious diseases as well as some skin conditions. Through Push Health, people who might need a doxycycline prescription can connect with a licensed medical provider who can prescribe the medication when appropriate to do so.

What Is Doxycycline Used For?

Doxycycline prescription medication is a medication (available both orally and in an intravenous form) that, like minocycline, belongs to a class of broad-spectrum antibiotics known as tetracyclines. Marketed under the brand names Doryx, Oracea, Vibramycin and others, doxycycline has a wide range of uses in the treatment of bacterial and parasitic infections:

Acne Treatment

Doxycycline is one of the most commonly prescribed oral antibiotics for acne treatment (moderate to severe) when topical treatment is not adequate. It helps treat a bacteria called Cutibacterium acnes and reduces inflammation. Typical courses last weeks to months and it often works better when used with topical therapies such as benzoyl peroxide or a retinoid. It is not intended as a lifelong treatment. A lower-dose anti-inflammatory formulation - doxycycline 40 mg modified-release (Oracea) - is FDA-approved for rosacea.

Chlamydia / other STIs

Doxycycline 100 mg twice daily for 7 days is a preferred treatment for uncomplicated urogenital chlamydia treatment in many non-pregnant adults. It may also be used in selected combination regimens for other STI syndromes. Partners should be treated and abstinence from sex is recommended until treatment is complete and partners are notified and treated.

DoxyPEP

DoxyPEP is a single 200 mg dose of doxycycline ideally taken within 24 hours and no later than 72 hours after a potential exposure to bacterial sexually transmitted infections (STIs) such as chlamydia and syphilis and gonorrhea to a lesser extent. It does not prevent HIV and is not a substitute for condoms, STI testing, or HIV prevention strategies including PrEP.

Malaria Prevention

For some destinations (e.g. sub-Saharan Africa, Southeast Asia, Central and South America, and the Pacific), doxycycline is used for malaria prophylaxis. A common regimen is doxycycline 100 mg once daily started 1-2 days before travel, continued during exposure, and for 4 weeks after leaving the risk area. Sun protection is especially important.

Other Uses

Doxycycline's other clinical roles include Lyme disease treatment and selected community-acquired infections when resistance isn't an issue.

Doxycycline - Dosage and Cost

Doxycycline is commonly available in 50 mg, 75 mg, 100 mg, and delayed-release forms. The dose and duration used depend on the indication. Doxycycline is typically inexpensive, costing under $1 per tablet at most major pharmacies. Insurance and prescription discount cards may also be available to reduce costs.

Can I drink alcohol while taking doxycycline?

Occasional alcohol use is not strictly contraindicated, but avoiding alcohol during treatment is advised as it can affect medication levels and tolerability.

How does doxyPEP differ from PrEP?

What should I avoid while taking doxycycline?

While on doxycycline, avoid taking antacids, dairy products, calcium supplements, iron supplements, or magnesium-containing vitamins within 2 hours of a dose as these can reduce absorption.
