Hi Shailja,
Thank you for writing in.
I am a medical specialist with an additional degree in cardiology.
The rashes can be present as drug reaction, allergy or scabies a skin doctor (
dermatologist) after examination can tell you. Rarely, worm infestation can cause itching but usually not generalized rashes. For Giardia,
albendazole is rarely effective. The most common treatment for giardiasis is
metronidazole (Flagyl) for 5-10 days. It eradicates the Giardia more than 85% of the time, but it often causes gastrointestinal side effects such as nausea and a
metallic taste as well as dizziness and headache. Despite its effectiveness, metronidazole is not approved by the FDA in the U.S. for treatment of giardiasis.
The only drug approved for treating giardiasis in the U.S. is
furazolidone (Furoxone) for 7-10 days. It is approximately as effective as metronidazole. Tinidazole is available in INDIA . and is highly effective at treating giardiasis(>90%). It also can be given as a single dose (for 3 year old dose will be 100 mg once a day for 3 days and is well tolerated. Paromomycin and albendazole are less effective than other treatments.
With Best Wishes.
