How is filarial treated?
The main goal of treatment of an infected person is to kill the adult worm. Diethylcarbamazine citrate (DEC), which is both microfilaricidal and active against the adult worm, is the drug of choice for lymphatic filariasis. The late phase of chronic disease is not affected by chemotherapy.
How long does it take to treat microfilaria?
If a patient has a low level of microfilariae in the blood (< 2500/mL), he or she can be safely treated with DEC 8-10 mg/kg/d for 21 days. If microfilarial levels are higher, patients should be treated only if they are symptomatic.
Does albendazole kill microfilariae?
Authors' conclusions. There is good evidence that albendazole makes little difference to clearing microfilaraemia or adult filarial worms in the 12 months post‐treatment. This finding is consistent in trials evaluating albendazole alone, or added to DEC or ivermectin.
What kills heartworm microfilaria?
Topical moxidectin is now FDA-approved for use in heartworm-positive dogs to eliminate microfilariae. No adverse reactions due to high microfilarial counts were observed in the laboratory or field studies conducted for approval of this label claim. Macrocyclic Lactone/Doxycycline.
What are the symptoms of microfilaria?
Symptoms may include itchy skin (pruritis), abdominal pain, chest pain, muscle pain (myalgias), and/or areas of swelling under the skin. Other symptoms may include an abnormally enlarged liver and spleen (hepatosplenomegaly), and inflammation in the affected organs.

Can doxycycline cure filariasis?
Ivermectin and albendazole are medicines used to treat lymphatic filariasis. They eliminate the Wb parasite from the blood but do not affect Mp. Doxycycline is used to treat many kinds of infections and has also recently been shown to reduce the number of filarial worms in several types of filarial infections.
Does albendazole kill filaria?
Albendazole was considered for lymphatic filariasis after a study reported that high doses given over several weeks caused serious adverse reactions suggestive of adult worm death. A WHO informal consultation report then proposed that albendazole has a killing or sterilizing activity on adult worms.
What is anti filarial drug?
Abstract. Diethylcarbamazine and suramin are the drugs of choice for the control of lymphatic filariasis and onchocerciasis respectively. Benzimidazoles, ivermectin, furapyrimidone, and isothiocyanates and their derivatives emerge as compounds of potential clinical interest as antifilarials.
How does doxycycline work for heartworms?
Doxycycline has been used to (presumably) rid the parasite of Wolbachia organisms; therefore, D immitis organisms do not thrive, may deteriorate and die, and have reduced reproductive potential, which helps manage HWD in infected dogs and reduces potential for infection in other dogs.
Can doxycycline treat heartworms in dogs?
The American Heartworm Society recommends treatment with doxycycline in dogs diagnosed with heartworm disease at a dose of 10 mg/kg twice daily for 28 days.
Why is prednisone prescribed with heartworm treatment?
During this treatment your pet will begin taking Prednisone (a steroid) to help reduce inflammation in the lungs and vessels, caused by the worms before and after they die. Prednisone also helps reduce the risk of an acute pulmonary embolism (clot) that can cause sudden death.
