It's known for its convenient, short-course dosing regimen.

Beyond these, you might encounter other antibiotics like Metronidazole (often sold as Flagyl), used for parasitic and bacterial infections, and Sulfamethoxazole and Trimethoprim (Bactrim), a combination antibiotic for various bacterial infections, including UTIs. For topical applications, there are various antibiotic ointments and creams available in Mexico for minor skin infections.

For specific concerns like tooth infections, amoxicillin is a common choice, often in 500mg doses. For antibiotics for UTI, various broad-spectrum antibiotics might be available such as Nitroflurantoin and Fosfomycin.

Are Antibiotics from Mexico Safe?

Buying antibiotics in Mexico is generally safe as long as you purchase them from large pharmacy chains such as farmacia Guadalajara, farmacia San Pablo, and farmacia del ahorro. There are significant risks associated with purchasing drugs, especially antibiotics, without a prescription or from unverified sources.

Another issue is antibiotic resistance. Many smaller independant mexican pharmacies still sell antibiotics without a prescription. When antibiotics are taken unnecessarily, incorrectly, or for conditions they cannot treat (like viral infections), bacteria can develop resistance, making future infections harder to treat. This is a global health crisis, and contributing to it by self-prescribing or misusing antibiotics can have severe consequences for individual and public health.

When is it time to see an infectious disease specialist?

For chronic or recurrent infections, or infections that are hard to treat due to antibiotic resistance or other unexplainable reasons, you should consult an infectious disease specialist.

Furthermore, without a proper medical diagnosis, you might be taking the wrong antibiotic for your condition, or an antibiotic that interacts negatively with other medications you are taking. A healthcare professional can accurately diagnose your illness, prescribe the appropriate antibiotic, and advise on the correct dosage and duration of treatment.

Red Flags to Watch Out For

If you are considering purchasing antibiotics in Mexico, be wary of:

• Pharmacies that offer significantly lower prices than others, as this could be a sign of counterfeit products.
• Pharmacies that do not require any form of consultation or prescription for antibiotics.
• Medications that look different from what you expect (e.g., unusual color, shape, or packaging for example amoxicillin should be red and white or red and orange").
• Lack of clear labeling or expiration dates.

Can I Bring Antibiotics to the US from Mexico?

According to the FDA, you can bring back antibiotics from Mexico to the USA as long as it doesn't exceed a 90 day supply. Border officers might ask you for a prescription for the antibiotic that you are bringing back.
