Pharmacist tips for Clarithromycin

pharmacist

  • Take clarithromycin extended-release tablet with food. Make sure to swallow it whole. Don't crush, chew, or break the tablet.

    • Take clarithromycin exactly as prescribed. Make sure to finish the entire treatment course, even if you're feeling better. Stopping the medication earlier than prescribed can make your infection come back and become harder to treat.

      • If you develop watery or bloody diarrhea, fever, fatigue, or stomach cramps anytime during treatment or after stopping clarithromycin, seek medical help right away because these could be signs of C. difficile-related diarrhea, which needs to be treated right away.

        • Clarithromycin can leave a metallic or sour taste in your mouth, but this should get better and eventually go away when you stop taking the medication.

          • If you experience diarrhea from taking clarithromycin, let your provider know. If they think the diarrhea isn't too serious, they might recommend that you take a probiotic to help lessen this side effect. If so, make sure to separate the probiotic from clarithromycin by at least 2 hours to prevent clarithromycin from killing the "good" bacteria in the probiotic.

            • Clarithromycin interacts with a lot of commonly-used medications. Make sure to tell your provider about all of the medications you're taking before and during treatment with clarithromycin.

              More tips for the oral suspension (liquid)

              • The clarithromycin suspension is available as 125 mg/5 mL and 250 mg/5 mL strengths. Make sure you know which strength of the suspension you have to ensure you're taking the correct dose.

                • Shake the bottle well before measuring out the clarithromycin suspension. Make sure to only use a medication dose cup or syringe from the pharmacy to measure out your dose. Don't use household spoons because they aren't accurate and might cause you to take the wrong dose.

                  • Store the clarithromycin suspension at room temperature, don't put it in the refrigerator.

                    • The clarithromycin suspension can be stored for up to 14 days after you receive it from the pharmacy. After 14 days, throw away the bottle, even if it still has medication in it.

                      faqs

                      Frequently asked questions about Clarithromycin

                      Is clarithromycin a penicillin?
                      No. Clarithromycin is a macrolide antibiotic. It works differently from penicillin. Both antibiotics are used to treat similar infections, but they're not the same. This means depending on what infection you have, clarithromycin might be a good option if you're allergic to penicillin.
                      Can you drink alcohol while you're taking clarithromycin?
                      It's best to avoid drinking alcohol while taking antibiotics like clarithromycin. This is because alcohol can make it harder for your body to heal from an illness and can raise your risk of getting another infection.
                      What drug interactions are there with clarithromycin?
                      There are several medications that interact with clarithromycin, so it's important your provider and pharmacist know about all of the medications you're taking. For example, you shouldn't take clarithromycin with lovastatin or simvastatin (Zocor) because doing so raises your risk for severe liver or muscle problems from these medications. And if you're taking other medications, like atorvastatin (Lipitor), digoxin (Lanoxin), and calcium channel blockers, your provider your provider might need to adjust your medication doses and check in with you about side effects regularly throughout treatment. Make sure to tell your provider about all of the medications you're taking before and during treatment with clarithromycin.
                      What's the difference between clarithromycin and azithromycin (Zithromax)?
                      Both clarithromycin and azithromycin (Zithromax) are macrolide antibiotics that work well and can treat similar infections. But only clarithromycin can be used for Helicobacter pylori (H. pylori) infection and only azithromycin (Zithromax) can be used to treat certain types of sexually transmitted infections. Additionally, the length of treatment depends on the type of infection, but in general, it's 7 to 14 days with clarithromycin, whereas with azithromycin (Zithromax), it can range from a single dose to up to 5 days.
                      How long does clarithromycin stay in your system?
                      If you have healthy kidneys, clarithromycin can stay in your body for about 1.5 days after your last dose. But if you have kidney problems, it can take much longer for your body to clear this medication. So if you're having side effects from clarithromycin, it's possible they could potentially last up until the medication has been cleared from your body. Keep in mind that these time frames are estimated based on the half-life of clarithromycin, which can differ slightly from person to person.
                      Can I take clarithromycin if I'm pregnant?
                      Clarithromycin isn't generally recommended in pregnant females due to the potential risk for problems (e.g., heart problems, cleft palate) seen in animal studies. The risk of harm to human babies isn't completely clear. A 2021 human study found that babies born to pregnant females taking clarithromycin weren't harmed. If you're pregnant, your provider might only prescribe clarithromycin for you if there aren't any safer options and if the benefits of taking this medication is greater than its risk of harm. Let your provider know if you're pregnant before taking clarithromycin.
                      Can I take clarithromycin if I'm breastfeeding?
                      It's generally considered safe to breastfeed while taking clarithromycin because the levels of the medication are low in breastmilk and unlikely to cause side effects to your baby. But to be safe, tell your provider if you're breastfeeding before starting clarithromycin.

                      What are the risks and warnings for Clarithromycin?

                      Clarithromycin can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.

                      risk-warning

                      Severe allergic and skin reactions

                      Severe allergic reactions to clarithromycin are possible, including life-threatening reactions like facial swelling and anaphylaxis (e.g., closing of the throat). Let your provider know if you have an allergy to antibiotics. If you notice hives, rash, red skin, swelling of the lips or tongue, or difficulty breathing after taking clarithromycin, get medical attention right away.

                      Additionally, although rare, clarithromycin can cause serious skin reactions, such as Stevens-Johnson syndrome (SJS) and Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS). If you notice changes in your skin, such as rash, blisters, skin reddening, or skin peeling, stop using clarithromycin and get medical attention right away.

                      risk-warning

                      Liver damage

                      Though rare, some people who took clarithromycin reported serious liver problems, including liver failure. Get medical attention right away if you notice swelling of your stomach, stomach pain, yellowing of your skin or the whites of your eyes, stool changes (clay-colored stools), nausea, vomiting, confusion, or dark or brown urine. You might need to stop using the medication to prevent further liver damage.

                      risk-warning

                      Drug interactions

                      Taking clarithromycin with certain medications can give you serious side effects. Make sure to tell your provider about all of the medications you're taking, especially if you take colchicine (Colcrys, Mitigare), Juxtapid (lomitapide), a statin, certain diabetes medications (e.g., insulin, sulfonylureas, meglitinides), quetiapine (Seroquel), oral blood thinners, or benzodiazepines (e.g., alprazolam (Xanax). Don't start any new medications while taking clarithromycin without asking your provider or pharmacist first to make sure the combination is safe to take.

                      risk-warning

                      Heart rhythm problems (QT prolongation)

                      • Risk factors: Older adults | Low blood potassium or magnesium levels | Kidney problems | Heart rate or heart rhythms problems | Taking other medications that can cause QT prolongation

                        Clarithromycin can affect your heart rhythm, which can be serious and life-threatening. One example includes lengthening the time period from when the heart pumps and then relaxes. This is known as QT prolongation. Your risk for QT prolongation is higher if you have certain factors, including abnormal electrolyte levels, heart rhythm problems, or are taking other medications that cause heart rhythm problems, such as amiodarone (Pacerone), among others. If you feel your chest pounding, have trouble breathing, have chest pain, or feel faint or lightheaded while taking clarithromycin, call 911 right away.

                        risk-warning

                        Possible higher risk of death from heart problems

                        • Risk factors: Blood vessel-related heart problems

                          Though very rare, some studies have reported that people with blood vessel-related heart disease who take clarithromycin are at a higher risk of death from heart problems compared to people who take other antibiotics. While the connection is unclear, your provider will weigh the risks and benefits of this medication for you, especially if you have heart problems. Speak to your provider if you have any concerns.

                          risk-warning

                          Infectious diarrhea

                          Although rare, clarithromycin can raise your risk of getting infected with a bacteria called Clostridioides difficile (C. diff), which can cause severe diarrhea. Antibiotics change the amount of normal bacteria in your stomach and intestines. This can cause C. diff to overgrow in your gut and lead to an infection. It's important to recognize the difference between diarrhea as a side effect of clarithromycin and this type of infectious diarrhea. C. diff-related diarrhea can cause rapid heart rate, foul-smelling diarrhea, fever, nausea, frequent bowel movements (even up to 15 times per day) and is an emergency. If you have any of these symptoms, get medical attention right away so you can get tested for C. diff infection and receive treatment.

                          risk-warning

                          Worsening of certain muscle problems (myasthenia gravis)

                          If you have myasthenia gravis, taking clarithromycin can worsen symptoms like muscle weakness and difficulty breathing. Ask your provider about safer antibiotics if you have myasthenia gravis.
