Know which medicines are common in your area

9.3 Know which medicines are common in your area Once the common parasites are identified, the most appropriate and inexpensive medicine can usually be found in the local market. Every medicine should be from a reputable source and have a label indicating for which parasites it is effective. Sometimes only the scientific names are listed on a label. Therefore, you may need the assistance of a veterinary doctor or someone else who knows these scientific names.

Examples of various worm medicines Note: Animals that have had a chronic or severe load of parasites can remain sickly even after treatment if the parasites have already caused permanent damage to the animal's internal organs. Therefore livestock owners should give parasite medicine routinely to avoid the permanent damage.

Note: Parasites can become resistant to medicines that have been used for a long period of time in an area. When a certain medicine that once worked no longer works, the parasite may have become resistant and a change in medicine is necessary.
