Clavam 625 Tablet: Uses, Dosage and Safety Guide

Clavam 625 is a fixed-dose combination tablet containing amoxicillin and clavulanic acid, two ingredients that together treat a range of bacterial infections - including infections of the ears, sinuses, chest, urinary tract, skin and bones. It belongs to a group of antibiotics called penicillins, combined with a beta-lactamase inhibitor that helps amoxicillin work against tougher bacteria. It is available in India only against a doctor's prescription.

Each Clavam 625 tablet contains amoxicillin 500 mg (as amoxicillin trihydrate) and clavulanic acid 125 mg (as potassium clavulanate). Amoxicillin is a penicillin-type antibiotic. Clavulanic acid does not fight infection on its own, but it protects amoxicillin from being broken down by certain bacterial enzymes, which widens the range of bacteria the combination can treat.

Clavam is also available as Clavam 375 (amoxicillin 250 mg + clavulanic acid 125 mg) and Clavam 1000 (amoxicillin 875 mg + clavulanic acid 125 mg) tablets. These strengths are not interchangeable — two Clavam 375 tablets are not the same as one Clavam 625 tablet, and a doctor chooses the strength based on the infection and its severity. This article covers the 625 mg tablet only.

• Variant: Clavam 375; Amoxicillin: 250 mg; Clavulanic acid: 125 mg
• Variant: Clavam 625; Amoxicillin: 500 mg; Clavulanic acid: 125 mg
• Variant: Clavam 1000; Amoxicillin: 875 mg; Clavulanic acid: 125 mg

Clavam 625 is manufactured by Alkem Laboratories. Since several antibiotics have similar-sounding names, it helps to check the strip for the exact name and strength your doctor has written on the prescription.

Clavam 625 is a prescription-only medicine in India. A pharmacist cannot legally sell it to you without a valid prescription from a registered doctor.

Amoxicillin works by blocking the enzymes bacteria need to build their cell walls. Without a properly formed cell wall, the bacteria weaken and die. Some bacteria produce an enzyme called beta-lactamase that destroys amoxicillin before it can act. Clavulanic acid blocks this enzyme, which stops it from breaking amoxicillin down and allows amoxicillin to keep working against bacteria it would otherwise not be able to treat.

A doctor may prescribe Clavam 625 for short-term treatment of bacterial infections such as:

• Ear, nose and throat infections, including sinusitis and recurrent tonsillitis
• Chest infections, such as flare-ups of chronic bronchitis and pneumonia
• Urinary tract infections, including cystitis and kidney infections
• Skin and soft tissue infections, such as boils, abscesses and wound infections
• Bone and joint infections

What it is not for. Clavam 625 does not work against viral illnesses. It should not be used for the common cold, flu, or most sore throats, since these are usually caused by viruses, not bacteria. Taking an antibiotic for a viral illness does not help you recover faster and only adds to the risk of antibiotic resistance. Clavam 625 is also not appropriate for infections known or suspected to be resistant to penicillin-type antibiotics, and it should generally be avoided if a doctor suspects infectious mononucleosis (glandular fever), since amoxicillin can trigger a rash in that condition.

Take Clavam 625 exactly as your doctor has prescribed. According to the manufacturer's prescribing information, adults are typically prescribed:

• One Clavam 625 tablet two or three times a day for mild-to-moderate infections
• One Clavam 625 tablet three times a day for more severe infections, including recurrent urinary infections and chest infections

Your doctor decides the exact frequency and how many days you need to take it for, based on the infection being treated. Treatment is not usually continued beyond 14 days without a review.

Practical points to keep in mind:

• With food. Take Clavam 625 at the start of a meal. This is when the clavulanic acid component is absorbed best, and it also reduces the chance of an upset stomach.
• Timing. Try to take each dose around the same time every day so the medicine stays at a steady level in your body.
• Splitting or crushing. Do not split, crush or chew the tablet unless your doctor or pharmacist has specifically told you it is safe to do so for your situation.
• Missed dose. Take the missed dose as soon as you remember. If it is almost time for your next dose, skip the missed one and continue your normal schedule. Do not take a double dose to make up for a missed one.
• Do not stop early. Even if you feel better after a couple of days, continue taking Clavam 625 for as long as your doctor has prescribed. Stopping too soon can leave some bacteria alive, let the infection come back, and allow bacteria to become resistant to the antibiotic.
• Overdose. An overdose can cause stomach upset, disturbed fluid and salt balance, and, in some cases, crystals forming in the urine or fits, particularly in people with reduced kidney function. If an overdose is suspected, go to the nearest hospital emergency department immediately and carry the medicine strip with you.

Dosing in kidney problems

Amoxicillin and clavulanic acid are cleared from the body mainly through the kidneys, so people with reduced kidney function may need a different dosing schedule.

• Above 30 mL/min — Usual dose, no change needed
• 10–30 mL/min — Same tablet strength, taken less frequently
• Below 10 mL/min — Same tablet strength, taken once daily

*The exact schedule is decided by your doctor based on your kidney function tests and the infection being treated.

Do not take Clavam 625 if:

• You have ever had any known allergy or hypersensitivity reaction to amoxicillin, penicillin or any other penicillin-type antibiotic — regardless of how mild the reaction was.
• You have had a serious allergic reaction (such as swelling of the face or throat, severe rash, or difficulty breathing) to another beta-lactam antibiotic such as a cephalosporin.
• You have previously developed jaundice or liver problems linked to amoxicillin-clavulanic acid.

Tell your doctor before taking Clavam 625 if you:

• Have a history of other drug or food allergies, or an uncertain or unclear allergy history that needs checking
• Have liver disease, or have ever had liver problems
• Have reduced kidney function
• Are pregnant, trying to become pregnant, or breastfeeding
• Have mononucleosis (glandular fever) or a condition that lowers your immunity
• Are due to have a urine glucose test, as this medicine can interfere with certain test methods

Children. Clavam 625 is generally used in adults and children who weigh 40 kg or more. Lighter children are usually prescribed a lower-strength tablet or a suspension, dosed according to body weight — your doctor will decide the exact product and amount.

Pregnancy and breastfeeding. Animal studies have not shown the combination to cause birth defects, but as with most medicines, it should be used in pregnancy only if a doctor considers it clearly necessary. It can be used during breastfeeding; trace amounts pass into breast milk, and there is a small risk of the baby becoming sensitised to the antibiotic. Tell your doctor if your baby develops any unusual symptoms.

Elderly. No dose change is usually needed for age alone, but older adults are more likely to have reduced kidney function, so your doctor may monitor this during treatment.

Common, usually mild side effects

• Diarrhoea
• Nausea or vomiting
• Indigestion or upset stomach
• Vaginal itching or discharge (in women)
• Skin rash, itching or hives

Serious side effects — seek urgent medical care

Call your doctor immediately or go to the nearest emergency department if you notice:

• Swelling of the face, lips, tongue or throat, wheezing, or difficulty breathing or swallowing — signs of a severe allergic reaction
• Widespread skin rash with blistering, peeling or mouth sores
• Watery or bloody diarrhoea with stomach cramps or fever, including if this starts weeks after you finish the course
• Yellowing of the skin or eyes, dark urine, unusual tiredness, loss of appetite, or easy bruising — possible signs of liver involvement
• A return of fever, sore throat or other infection symptoms after treatment, which could mean a new or resistant infection

Liver-related side effects are uncommon but are reported more often in men, older adults and people on longer courses of treatment; signs can appear during treatment or several weeks after it ends.

Driving and machinery. Clavam 625 can occasionally cause dizziness or, rarely, seizures, which may affect your ability to drive or operate machinery. Be cautious until you know how the medicine affects you.

Alcohol. There is no specific dangerous interaction listed between alcohol and Clavam 625. However, because this medicine can rarely affect the liver, many doctors advise limiting alcohol while you are on antibiotics and recovering from an infection.

Tell your doctor or pharmacist about every medicine, supplement or herbal product you are taking. Clavam 625 can interact with:

• Methotrexate — amoxicillin can reduce how quickly the body clears methotrexate, raising the risk of methotrexate side effects.
• Oral anticoagulants (such as warfarin or acenocoumarol) — this combination can occasionally increase bleeding tendency; your doctor may want extra blood tests during treatment.
• Probenecid — this medicine slows down how quickly amoxicillin is removed from the body and is not usually recommended together with Clavam 625.
• Allopurinol — taking this alongside amoxicillin may increase the chance of a skin rash.
• Hormonal contraceptives (birth control pills, patches, rings or injections) — Clavam 625 may reduce their effectiveness. Use an additional contraceptive method while taking this antibiotic.

• Store Clavam 625 tablets below 25°C, in a dry place away from moisture.
• Keep the strip in its original packaging and out of the sight and reach of children.
• Do not use the tablet past its expiry date printed on the strip.
• Do not share your prescription antibiotic with anyone else, even if they have similar symptoms.
• Dispose of leftover or expired tablets responsibly rather than flushing them or throwing them in household waste; ask your pharmacist about safe disposal.
• Remember that Clavam 625 is a prescription-only medicine in India — a pharmacist cannot dispense it without a valid prescription.

Antibiotic resistance is one of the more serious public health problems India faces today. When bacteria are exposed to antibiotics but not fully eliminated — because a course was stopped early, doses were skipped, or the antibiotic was taken for an infection it could never have treated — some bacteria survive and can become resistant. These resistant bacteria can then spread to other people, making future infections harder, slower and more expensive to treat.

This is why every point in this article about "how to take" Clavam 625 matters as much as the dose itself:

• Take the full course your doctor prescribes, even after your symptoms improve.
• Never take Clavam 625, or any leftover antibiotic, for a cold, flu, or ordinary sore throat — these are usually viral, and antibiotics will not help.
• Never use antibiotics left over from a previous illness or prescribed for someone else.

India's health authorities treat this seriously. Clavam 625 is a prescription-only medicine in India and cannot be sold without a valid doctor's prescription. The government has also run public awareness campaigns urging people not to buy or use antibiotics without medical advice. Globally, drug-resistant bacterial infections are already linked to millions of deaths a year, and resistance levels are estimated to be highest in the WHO regions that include South-East Asia — which is exactly why responsible antibiotic use by individual patients genuinely matters.

If your symptoms have not improved within a few days of starting Clavam 625, or they get worse, contact your doctor rather than stopping the medicine or changing the dose yourself.
