Parasite medicines: what works, when to get help, and how to buy safely
Parasite infections can be simple to treat — or they can need a doctor’s care. If you suspect a parasite, it helps to know the common medicines, what symptoms need testing, and how to buy real drugs without overpaying or risking fakes.
Common antiparasitic drugs and what they treat
Here are the medicines you’ll hear about most and the infections they usually target:
- Albendazole / Mebendazole — Often used for roundworms, hookworms, pinworms and some tapeworms.
- Praziquantel — Common for tapeworms and schistosomiasis (blood flukes).
- Metronidazole / Tinidazole — Used for protozoa like Giardia and Entamoeba histolytica.
- Ivermectin — Treats strongyloidiasis, some scabies cases and certain parasitic skin conditions.
These are general patterns. The exact drug, dose and length of treatment depend on the parasite species, your age, weight, pregnancy status and other health issues.
When to see a doctor and what to expect
Get checked if you have: ongoing diarrhea, bloody stools, unexplained weight loss, persistent abdominal pain, fever after travel, or a rash that won’t go away. A clinician may order stool tests, blood tests, or imaging. Don’t guess the parasite — treatment changes a lot based on the finding.
If a doctor prescribes medicine, follow the dose and finish the full course. Some antiparasitics can interact with other drugs or harm the liver. Pregnant people and young children need special attention — never self-treat without medical advice.
Not sure where to start? Ask your local clinic for a stool test or a referral. A quick lab result often saves time and avoids wrong medicines.
Buying medicines in Mexico — practical tips
Mexico is a common place to buy antiparasitics because many drugs are cheaper and some are available over the counter. Use these steps to stay safe:
- Buy from licensed pharmacies with visible contact info and a physical address.
- Ask for the active ingredient (albendazole, praziquantel, etc.) rather than just a brand name.
- Check packaging, expiry date and that the leaflet is included and in Spanish or English.
- Avoid extremely low prices or sellers that won’t provide batch numbers or receipts.
- If buying online, prefer sites linked to a known Mexican pharmacy chain and use secure payment methods.
Remember: some antiparasitics do require a prescription in Mexico. Bringing your doctor’s note speeds the process and reduces risk.
