Can I take amoxicillin with coffee?

In this text we will answer whether or not you can drink coffee with amoxicillin, as well as give some tips on other foods that should not be ingested while using this medication.

Can I take amoxicillin with coffee?

Yes, it’s okay to take amoxicillin with coffee. There is no record of interactions between amoxicillin and the caffeine present in coffee. However, this does not necessarily mean that there are no interactions. The ideal is to consume any type of medicine with water.

However, since tea and coffee contain caffeine, it should be consumed in moderation, as in large amounts it can increase the side effects of the antibiotic and also increase its excretion, in addition to causing irritation and excitement.

Can I take antibiotics with coffee and milk?

Although not harmful to health, antibiotics are medicines that should not be taken with milk, because the calcium present in milk reduces its effect on the body.

Fruit juices are also not always recommended, as they can interfere with their action, increasing their absorption speed, which ends up reducing their action time. Therefore, water is the most suitable liquid to take any medication, as it is neutral and does not interact with the composition of the medication, ensuring its effectiveness.

Should I take amoxicillin on a full or empty stomach?

Amoxicillin can be taken on a full stomach. This doubt permeates many people and many mistakes are made when it comes to taking the drug before or after meals. Many foods can also interact with medications, disrupting or not their effect on the body.

So, the ideal is always to read the medication leaflet where, most of the time, it contains the information whether or not we can take the medication on a full stomach or not.

Sometimes a full stomach can interfere with the absorption or metabolism of a drug. Other times a full stomach can protect the stomach lining from irritation caused by the medication. Example: Hard gelatin capsules irritate an empty stomach.

There are some medicines that we must take on an empty stomach and we can only eat for about 2 hours after taking them.

Can I take amoxicillin with alcohol?

The answer is no. For many people, alcohol should only be avoided when taking antibiotics.

But in fact, medicine should NEVER be taken with alcoholic beverages.

Here are some examples of interactions between alcohol and medicines that are very harmful:

  • Alcohol and Painkillers: with paracetamol, it can cause severe liver damage; with aspirin (or acetylsalicylic acid-ASA) increases the risk of bleeding in the stomach and intestine, by increasing the anti-platelet aggregation action of AAS
  • Alcohol and Antihypertensives: can cause fainting and cardiac arrhythmias
  • Alcohol and Antidepressants: may potentiate the effect of the drug
  • Alcohol and Anxiolytics (tranquilizers): can cause central nervous system depression, respiratory arrest and coma
  • Alcohol and Medicines for obesity: can cause dizziness and mental confusion
  • Alcohol and Antibiotics: reduces the effect of the antibiotic partially or totally depending on the amount of alcohol consumed.

Excessive alcohol intake can also inhibit the action of the birth control pill.

Should I follow the treatment time prescribed by the doctor even without symptoms?

Yes, you should take amoxicillin for as long as your doctor prescribes.

Many people stop taking the drug as soon as their symptoms improve or lessen. This happens a lot with antibiotics that have longer treatments of at least 5 or 7 days and up to 14 or 21 days or more, in some specific cases.

In general, on the second or third day, the symptoms of the infection such as fever, pain and indisposition decrease or disappear, then the person thinks they have healed and stops the treatment.

This is the biggest mistake that a person can make in an antibiotic treatment, because the treatment is not over yet.

There are still strains of bacteria resistant to the antibiotic in the person’s body and, in the next opportunity, when the person’s immunity is low, these bacteria will reproduce, the person will get sick again and the first antibiotic (the one left over from the prescription that the doctor gave you and you thought you would use it again), will not solve the problem.

Taking the drug for longer than recommended can also cause problems. For example, anti-inflammatories like ibuprofen and diclofenac can cause kidney and liver problems if you take them for a long time without judgment and without your doctor’s advice.

Therefore, correctly follow the treatment time and the exact time that the drug should be taken.
