Doxycycline and amoxicillin are two commonly prescribed and used antibiotics in medicine. However, they belong to different drug classes and are often used for different types of bacterial infections.<\/span><\/p>\n

Doxycycline<\/span><\/a> is a tetracycline antibiotic that works by stopping bacterial growth. It\u2019s typically prescribed for skin conditions like rosacea and acne because it also reduces inflammation. On the other hand, <\/span>Amoxicillin<\/span><\/a> is a penicillin antibiotic that kills bacteria, which is why it is often prescribed to people needing antibiotics for common illnesses like pneumonia, bronchitis, sinusitis, <\/span>urinary tract infections (UTIs)<\/span><\/a>, and the stomach infection <\/span>H. pylori<\/span><\/i>.<\/span><\/p>\n

Although it may seem unusual to take more than one antibiotic at a time, this strategy can be helpful if the right drug combinations are carefully chosen and given together. According to <\/span>Raj Singh<\/span><\/a>, MD, primary care physician at HEALOR and medical director at RAREV Medical Spa in Las Vegas, using multiple antibiotics at once may increase the effectiveness of your treatment, helping you get better faster. It can also reduce the likelihood of bacteria-resistant infections.\u00a0<\/span><\/p>\n

But what about taking doxycycline and amoxicillin together\u2014is this a good combination? While technically safe, it\u2019s usually not the best pairing, and healthcare providers generally avoid combining these two antibiotics. Here\u2019s what to know.\u00a0<\/span><\/p>\n

Why can\u2019t you take doxycycline and amoxicillin together?<\/span><\/h2>\n

\u201cTaking doxycycline and amoxicillin at the same time isn\u2019t unsafe, but it\u2019s not a preferred combination,\u201d Dr. Singh says. Lab studies have shown that tetracycline antibiotics (like doxycycline) can reduce the effectiveness of other antibiotics, particularly <\/span>penicillin-type antibiotics<\/span><\/a> (like amoxicillin). In other words, taking doxycycline and amoxicillin together could make it harder for the amoxicillin to work as effectively as it should.\u00a0<\/span><\/p>\n

Does that mean these two antibiotics can never be prescribed at the same time? \u201cNot necessarily,\u201d says Dr. Singh. \u201cIf someone is on doxycycline for a month for a bad skin infection or acne, for example, and they get an ear infection, you could prescribe a short course of amoxicillin. It\u2019s not unsafe; we just don\u2019t know if the amoxicillin will be as effective as it could be.\u201d<\/span><\/p>\n

However, you should make sure you communicate with your healthcare providers about all of the prescription drugs, including over-the-counter (OTC) medicines, vitamins, minerals, and herbs you\u2019re taking, especially if you need to be prescribed more than one antibiotic at the same time. This is especially important if you have multiple healthcare providers who may not be aware of what the others have prescribed.<\/span><\/p>\n

\u00a0<\/span>\u201cYou could be prescribed one of these antibiotics by a specialist, like a dermatologist, and another by a primary care doctor,\u201d says <\/span>Joanna Lewis<\/span><\/a>, Pharm.D., founder of The Pharmacist\u2019s Guide. \u201cIt\u2019s always important to let all providers know all of the medications you are taking so they can educate, monitor, and change therapy as needed.\u201d<\/span><\/p>\n

\u201cThere is also the possibility that being prescribed both of these antibiotics at once could increase the potential for some of the more common gastrointestinal <\/span>side effects<\/span><\/a> such as nausea, vomiting, diarrhea, and stomach pain,\u201d Dr. Lewis says.<\/span><\/p>\n

Is doxycycline or amoxicillin better?<\/span><\/h2>\n

There are several <\/span>differences between doxycycline and amoxicillin<\/span><\/a>. These drugs are often prescribed to treat different bacterial infections, so one isn\u2019t necessarily better than the other. The choice between them may depend on the type of infection your healthcare provider is treating.\u00a0<\/span><\/p>\n

Drug class\u00a0<\/span><\/h3>\n

Doxycycline is a tetracycline antibiotic, and amoxicillin is a penicillin-type antibiotic. According to Dr. Singh, this means they work differently. \u201cDoxycycline is what we call a bacteriostatic antibiotic, which means it prevents the growth of bacteria, [while] amoxicillin is considered a bactericidal, which means it kills bacteria.\u201d<\/span><\/p>\n

Uses<\/span><\/h3>\n

Because these antibiotics treat infections differently, they\u2019re used for different conditions. Dr. Singh says doxycycline can be used for malaria and tick bites but is generally used mostly for skin conditions like acne. On the other hand, he says amoxicillin is used more for ear, nose, and throat infections, including bronchitis and strep throat.<\/span><\/p>\n

Side effects<\/span><\/h3>\n

Both <\/span>amoxicillin<\/span><\/a> and doxycycline can cause mild gastrointestinal side effects, such as nausea, diarrhea, and vomiting. Both carry a risk for severe allergic reactions or anaphylaxis.\u00a0<\/span><\/p>\n

Doxycycline <\/span>is generally well-tolerated<\/span><\/a> compared to other drugs in its class and has limited evidence for causing serious adverse effects. However, it can cause additional mild side effects such as headaches, light sensitivity, itching or skin rashes, and, in rare cases, tooth discoloration.<\/span><\/p>\n

Pregnancy and breastfeeding risks<\/span><\/h3>\n

Pregnant and breastfeeding women should always consult with their healthcare provider about the safety of any OTC and prescription medications, natural supplements, and herbals. But generally, only one of these antibiotics is safe to use during pregnancy\u2014amoxicillin. \u201cDoxycycline is generally not recommended during pregnancy because it can impact the tooth and bone development of fetuses,\u201d Dr. Lewis says.\u00a0<\/span><\/p>\n

For breastfeeding, amoxicillin is typically considered safe, but you should use caution when taking doxycycline. \u201cIf the therapy is short-term, it may be allowed by your provider, but some prefer to avoid doxycycline during breastfeeding as well,\u201d Dr. Lewis says.\u00a0\u00a0<\/span><\/p>\n

Other drug interactions<\/span><\/h3>\n

Amoxicillin generally has few drug interactions. Dr. Singh says amoxicillin is, overall, a highly safe antibiotic with few side effects and drug-drug interactions. The only interaction he flags is with <\/span>allopurinol<\/span><\/a>, which is often prescribed to treat <\/span>gout<\/span><\/a>. \u201cTaking these two medications together increases the chance of having an allergic skin reaction, like a rash,\u201d Dr. Singh says.\u00a0<\/span><\/p>\n
