FAQ

A prescription is required to buy systemic chloramphenicol from local pharmacies in the United States. Under our store policy, you may place an order without submitting a prescription, and the product can be sent by mail.

Take the missed dose when you remember unless it is almost time for the next scheduled dose. In that case, skip the missed dose and resume the regular schedule. Do not take two doses at once.

Do not stop simply because symptoms improve; take chloramphenicol for the duration prescribed for the infection unless the prescriber tells you otherwise. Stopping early can leave an infection inadequately treated. New serious symptoms or suspected adverse effects require prompt medical assessment rather than independently extending or restarting the course.

Not necessarily. Products containing the same active ingredient, chloramphenicol, may use different capsule shells, colorants, fillers, or other inactive ingredients. The exact inactive ingredients of the supplied product should be checked on its received package or leaflet, especially for an allergy or intolerance.

Do not drive or operate machinery if chloramphenicol causes dizziness, headache, confusion, or visual changes. These effects are not expected in everyone, but vision or neurologic symptoms can make driving unsafe.

Chloromycetin contains chloramphenicol, an amphenicol antibiotic used for certain susceptible bacterial infections. Systemic chloramphenicol is generally reserved for serious infections when less hazardous antibiotics are ineffective or unsuitable, because it can cause severe blood disorders. It does not treat viral infections such as colds or flu.

Chloramphenicol should be avoided during pregnancy unless there is no safer appropriate alternative, particularly near delivery because of the risk of serious neonatal toxicity. It should also be avoided while breastfeeding because it passes into breast milk and may cause serious adverse effects in the infant.

Nausea, vomiting, diarrhea, sore mouth, headache, or rash can occur. Chloramphenicol can also cause serious, sometimes fatal bone-marrow suppression and aplastic anemia. Seek urgent medical attention for fever, sore throat, unusual bruising or bleeding, marked tiredness, pallor, or signs of infection.

Description

Chloromycetin is a drug in the broad-spectrum antibiotic family. It reduces numerous bacterial infections, including those of the blood, brain, lung, and other major organs. However, it is ineffective for viral illnesses, colds, or the flu.

Even if you see improvements in your health, never stop taking Chloromycetin earlier than suggested by your doctor. If you stop taking the drug too soon, it could make things worse. Until you know how this drug affects you, take caution when operating machinery, driving, climbing, or performing other risky actions. Avoid consuming alcohol. Before giving this medicine to a child, always contact a doctor.

Consult a physician if any of the following apply to you or have previously affected you: cardiac conditions (such as irregular heart rhythms), kidney or liver disease, anemia or other blood conditions, allergy to chloramphenicol or related drugs, foods, coloring materials, or preservatives, digestive or intestine issues, particularly colitis, dental issues, pregnancy, nursing, or intending to get pregnant.

Chloromycetin250mg

Chloromycetin is available as a liquid solution and capsule for oral use.

This drug is often taken in 50 milligrams (mg). It is advised to take medication four times a day, on schedule.

Some fluids should accompany this medication. When using Chloromycetin, it is best to drink multiple glasses of water daily to protect your kidneys. You can take it on an empty stomach or with food. Taking the medication with food lessens gastrointestinal discomfort and facilitates your body's absorption of the medication.

It is recommended to swallow the capsules whole. Never open, chew, break, or crush them.

For the medicine to be evenly mixed, give the beverage a good shake before using it. Use a measuring spoon or medicine cup with a designated marking to ensure you are taking the right amount.

As directed by your doctor and on the label of your prescription, take this medication as directed.

Try to take the dose as soon as you remember if you miss it. Take just one dose if it's time for your next one. The dosage doesn't need to be doubled.

Any medication used in excess might have detrimental effects on your health. Consult your healthcare physician right away if you believe you have overdosed.

  6. Warfarin Entacapone
  7. Birth control pills or oral contraceptives

This is not an exhaustive list of interactions. 

Talk to a doctor about using your medication with food, drink, or tobacco with your healthcare provider.

Customer questions

Asked by Marissa Coleman, San Francisco, United States

My order sat outside in the San Francisco heat for several hours before I found it. Can I still use the capsules?

Answered by Support team

Keep the package and check the labeled storage instructions: capsules should be stored at 68°F to 77°F in a tightly closed, light-resistant container away from moisture. Because the actual temperature and duration of exposure are unknown, do not rely on appearance alone; if the package, capsules, or seal look damaged or altered, have a pharmacist assess them before use.

Asked by Derrick Williams, Indianapolis, United States

I found a chloramphenicol generic at another online store for about half the price. Why should I order from you instead?

Answered by Support team

We stand behind the quality of the generic medicines we offer. We cannot verify what another seller supplies, how it is sourced or handled, or whether a similarly named lower-priced offer is truly equivalent in manufacturer, origin, or product quality. The choice is yours, but it is worth deciding whether the savings justify accepting that unknown seller risk.

Asked by Lauren Pierce, Denver, United States

Before I order, what package sizes can I choose for the 500 mg capsules?

Answered by Support team

The available package quantities are 60, 90, 120, 270, and 360 capsules. Select the quantity that matches the option shown when placing your order.

Asked by Ethan Morales, Boston, United States

I used chloramphenicol in a different form years ago. What form of Chloromycetin do you sell?

Answered by Support team

This listing is for oral chloramphenicol capsules in a 500 mg strength. It is not an eye drop, ointment, liquid, or topical product.

Asked by Natalie Brooks, Fort Worth, United States

I work irregular shifts and need to plan ahead. How are the 500 mg Chloromycetin capsules generally taken?

Answered by Support team
Medical reviewed by Spencer Hughes

These are oral capsules that should be swallowed with water, generally on an empty stomach unless the prescribed directions say otherwise. The dose, timing, and treatment duration depend on the infection and must be set by the prescriber; do not alter the schedule to fit a shift pattern without checking first.
