Giardiasis Treatment in Humans
In some cases, the giardia infection is asymptomatic and the patient feels no need for treatment unless it has the potential to spread the disease to the surrounding environment.
Although the parasite that causes this infection will disappear from the body by itself within a few weeks, the person with giardiasis may still have indigestion for some time. Patients with giardiasis who are dehydrated due to this condition will be advised to drink lots of water so that the body does not lack fluid and can perform its function properly.
The drugs used for giardiasis do not all give the same result to the sufferer. However, symptoms of severe giardia infection will usually be treated with immediate administration of antiparasitic drugs, such as:
- Metronidazole – The most common antibiotic used for giardiasis has several potential side effects such as nausea, and a metallic taste in the mouth after taking this drug.
- Nitazoxanide – This liquid-shaped drug is safe to use by children. Some side effects that can be caused include nausea, abdominal bloating, yellow eyes, and urine water is bright yellow.
- Tinidazole – A drug that has the same work, yield, and side effects as metronidazole but with a larger dose because it is given only once.
- Paromomycin – A drug that can be used by pregnant women, because it has a lower risk of birth defects than other antibiotics. However, pregnant women should take this drug after childbirth or consult an obstetrician.
Always follow the doctor’s instructions and the information contained in the drug package before taking them. Discuss with a doctor if the patient is an infant, pregnant woman, or has mild symptoms. The doctor will adjust the treatment according to the body’s condition, health, and patient’s response to treatment.
As mentioned earlier, giardiasis can cause sufferers to feel the symptoms even though the parasite has left the body. If not handled properly, patients (especially infants and children) are also at risk for complications such as:
- Dehydration. This is triggered by severe diarrhea and can disrupt the body in performing its functions.
- Lactose intolerance, ie the inability of the body to digest the sugar content in milk well, and can continue even if the infection has disappeared.
- Physical and mental development is hampered by malnutrition triggered by chronic diarrhea from this condition.
