In severe infections or anthrax: 100 mg IV twice daily (200 mg\/day) is common.

Doxycycline is primarily excreted unchanged in feces; in renal failure renal excretion falls but half-life is unchanged. However, in severe renal impairment (CrCl \u0026lt;10 mL\/min), be cautious and ensure adequate hydration (to avoid crystalluria). Hepatic impairment: moderately safe (no dosage change in mild-to-moderate); monitor liver enzymes in severe hepatic disease as with any tetracycline.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDuration:\u003c\/strong\u003e Generally treat at least 24–48 hours after symptoms resolve. Duration matches usual oral doxycycline (e.g. 7–10 days for pneumonia, at least 10–14 days for STDs).

It covers a wide range of infections including rickettsial diseases, pneumonia, certain STDs, anthrax, and others. The \u003cstrong\u003etypical regimen\u003c\/strong\u003e is 200 mg IV on day 1 (divided into one or two infusions), then 100–200 mg IV daily (often 100 mg q12h) depending on infection severity. Each dose is infused over at least 1 hour (250–500 mL IV fluids) to minimize vein problems. The total dose should not exceed ~200 mg\/day to avoid excessive toxicity. After reconstitution, the injected solution can be mixed into various IV fluids but must be clearly labeled “For IV use only”.\u003c\/p\u003e","brand":"Fosun Pharma USA","offers":[{"title":"Default Title","offer_id":53723416985968,"sku":"72266-0237-05P","price":110.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0996\/0350\/files\/Doxycycline-Hyclate-100-mg-Injection-Fosun-Pharma_80694964-ed4e-49ec-a605-1ef1d0f0284f.jpg?v=1778173372","url":"https:\/\/www.mountainside-medical.com\/products\/doxycycline-hyclate-100-mg-injection-single-dose-vials-x-5-box","provider":"Mountainside Medical","version":"1.0","type":"link"}
