There is no doubt that coffee is considered one of the beneficial drinks for human health, but it is important to stop drinking it after taking some medications, as it can negatively affect their effectiveness in the body. "Dalili Medical" reviews in the following report the medications that it is not recommended to drink coffee after, according to our website.

**What is the ideal time to drink coffee with medications?**

 

If you are taking one of the mentioned medications or any other medication, you should be aware that coffee contains chemicals known as tannins, which can interact with phenothiazines and reduce the body's absorption of the drug. To avoid this interaction, it is preferable to avoid drinking coffee an hour before taking medications and two hours after that.

**Do caffeine levels differ in different types of coffee?**

 

In addition to answering the question of how many cups of coffee are allowed per day, we need to consider the caffeine levels in coffee types. Caffeine levels vary between types in several ways. First, the type of coffee bean affects the caffeine content. There are two main types of coffee plants, Robusta and Arabica. In general, Robusta beans, which have a bitter, earthy flavor, contain twice as much caffeine as Arabica beans, which have a fruitier, sweeter flavor. Robusta beans are generally considered to be of lower quality and are used in most ready-to-drink brands.

Second, to understand how many cups of coffee you can drink per day, we need to consider how the method of brewing your coffee affects your caffeine levels.

The average caffeine content of brewed coffee, whether filtered, brewed using a coffee machine, or even a French press, ranges from 65-120 mg per standard 8-ounce cup. Filtered coffee, made using a V60 or Chemex, has a caffeine content of around 95 mg per cup of the same size.

For cold brewed coffee, which is often consumed in larger serving sizes such as 470 ml, the average caffeine content is around 200 mg per serving, while nitro brewed coffee can be as high as 325 mg for the same size. A 60 ml shot of espresso has between 60-102.7 mg of caffeine.

In terms of a single bean, both light roast and dark roast coffee contain the same amount of caffeine. However, because dark roast beans are roasted for longer, they lose more of their mass, meaning that when measured by caffeine per weight, dark roast beans will have a higher caffeine content.

What does caffeine do to the body?

 

Caffeine is a stimulant that affects the central nervous system, where it can cross the blood-brain barrier and increase activity. It also causes a slight increase in cortisol (the body’s main stress hormone) and adrenaline levels in the blood. For this reason, many people feel more alert, focused, and energetic after consuming caffeine. However, there can be negative cardiovascular effects when taken in large doses, such as heart rhythm disturbances. In addition, with chronic use and large amounts of caffeine, there may be a slight risk of reduced bone mineral density, which can lead to osteoporosis.

What is a safe amount of dietary caffeine intake?

 

The US Food and Drug Administration considers consuming 400 mg of caffeine per day to be safe for healthy adults, which is roughly equivalent to four cups of coffee, 10 cans of soda, or two shots of an energy drink. It is important to read the labels of caffeinated beverages, as caffeine content can vary greatly between different brands.

Why do caffeinated beverages affect medications?

 

Research has shown that caffeine consumption can affect the absorption, distribution, metabolism, and elimination of many medications. Caffeine-drug interactions can increase side effects, potentially leading to toxicity, or reduce the effectiveness of treatment. For example, diuretics (water pills) lower potassium levels, and caffeine also lowers potassium, so taking them together can lead to low potassium levels in the blood. Therefore, it is important to follow your doctor’s and pharmacist’s instructions regarding appropriate caffeine consumption while taking certain prescription medications.

How much coffee is safe to drink per day?

 

The recommended daily amount for healthy adults is about 400 mg of caffeine, which is roughly equivalent to 4 to 5 cups of coffee. Pregnant women and people with certain health conditions should significantly reduce this amount.

How much coffee can be fatal?

 

The lethal dose of caffeine is considered to be about 10,000 mg, which is roughly equivalent to 75 to 100 cups of coffee in a short period of time. This level of consumption is unrealistic under normal circumstances and can lead to death from caffeine poisoning.

Which is more harmful: tea or coffee?

 

Coffee has a higher caffeine content than tea, which can make it more harmful when consumed in large amounts, especially for people who are sensitive to caffeine. However, the effect of each depends on the dose, consumption pattern, and health condition of the individual, as both drinks can have benefits and harms.

In short, the number of cups of coffee you can drink per day depends on several factors, such as the type of coffee, your age, your health condition, and other factors. By following the instructions in this guide, you can enjoy your favorite coffee without any harm, and benefit from its benefits. And you will not find a better place than Covica to experience the distinctive and beneficial taste of coffee without any side effects.

**Medications to avoid taking with coffee**

 

1. **Beta-blockers**: Examples of these medications includePropranolol and atenolol. These medications lower blood pressure, but they may enhance the effect of caffeine in coffee, leading to increased heart rate and higher blood pressure.

2. **ACE inhibitors**: This class includes medications such as lisinopril and enalapril. These medications can lower blood pressure, and taking them with caffeinated coffee may increase this drop, increasing the risk of side effects such as dizziness and lightheadedness.

3. **Serotonin-Norepinephrine Reuptake Inhibitors**: Examples of these medications include venlafaxine and duloxetine. Taking coffee with these medications may increase nerve activity, which may cause increased anxiety and confusion.

5. Iron: Taking coffee with iron supplements may reduce the absorption of iron in the body. Therefore, it is usually recommended to avoid drinking coffee or caffeinated beverages while taking iron supplements to ensure better absorption of iron.

6 *Melatonin Melatonin is a natural hormone produced by the body to help you feel sleepy at night. This hormone is released after sunset, signaling to your brain that it is time to relax. Melatonin is also available over-the-counter (OTC) as a dietary supplement, and is used as a sleep aid. In contrast, coffee acts as a stimulant, making you feel more alert. The caffeine in coffee has the exact opposite effect of melatonin, which can increase your alertness and make it more difficult to fall asleep. Drinking coffee can inhibit the production of melatonin in the body, reducing its effectiveness. If melatonin and coffee are taken at the same time, they can interfere with each other’s effects.

7**Ephedrine** Ephedrine is a stimulant that speeds up the activity of the nervous system. It is used in the preparation of decongestants, and acts as a bronchodilator to treat breathing problems. It is also used to treat low blood pressure, menstrual problems, and other conditions. Since the caffeine in coffee is also a stimulant, combining ephedrine with coffee may have health risks. Health experts recommend avoiding mixing the two, as consuming them together may lead to high blood pressure, heart attacks, strokes, or seizures.

Medications to avoid drinking coffee after

1- Thyroid medications The effectiveness of thyroid medications may be negatively affected when drinking coffee immediately after, as coffee reduces the body's ability to absorb these medications.

2- Allergy medications It is important to separate the consumption of coffee and allergy medications, because combining them may exacerbate some symptoms, especially difficulty sleeping, due to excessive stimulation of the central nervous system.

3- Antibiotics Antibiotics can affect the metabolism of caffeine, leading to increased levels of caffeine in the blood. These medications are usually used to treat bacterial infections, such as urinary tract infections, bladder infections, infectious diarrhea, and sinus infections.

**- Diabetes medications**  Drinking coffee may negatively affect the health of some diabetics, especially when taken with medications to lower blood glucose levels, especially if it is sweetened with sugar or has milk added to it, as it has been shown that the caffeine in coffee may lead to increased levels of sugar and insulin in the body.

**Blood thinning medications**  Warfarin is one of the oldest and most common blood thinning medications, accounting for about a quarter of prescriptions for such medications in many countries around the world.

Caffeine can interfere with the breakdown of blood thinners, causing more of the medication to remain in the body, which can be dangerous, as taking too much of the medication can lead to excessive bleeding even from minor injuries such as paper cuts. For warfarin in particular, it is recommended to wait “at least six to eight hours” after drinking coffee, as this represents a “very significant drug interaction between warfarin and caffeine.” It is worth noting that newer blood thinners such as Elios should not cause such interactions, although warfarin is still the most common.

**- Alzheimer’s medications **Drinking coffee after taking Alzheimer’s medications may negatively affect their effectiveness in the body, as the caffeine in coffee can reduce the amount of medication that reaches the brain, in addition to hindering the drug’s ability to protect the neurotransmitter acetylcholine.

**- Asthma medications** Coffee should be avoided after taking asthma medications, as caffeine can reduce the body's absorption of these medications, increasing the likelihood of unpleasant side effects such as headaches, insomnia, and stomach pain.

**- Osteoporosis medications** The effectiveness of osteoporosis medications is significantly affected, as it can decrease by more than 50% when coffee is consumed immediately after taking these medications.

**. Gastroesophageal reflux** Acid reflux medications are most effective when taken early in the morning. When coffee is drunk with or after it, the acid in the coffee may exacerbate the problem for which the medication is being taken.

**. Leg swelling** In general, caffeine works to inhibit the hormone that stimulates water retention, making it a diuretic. This means that the caffeine in coffee can enhance the effectiveness of diuretic medications, such as those used to treat leg swelling.

. Heart Failure Due to the diuretic properties of caffeine, patients taking medications for heart failure should be cautious when consuming caffeinated coffee.

. High Blood Pressure When taken with coffee, medications used to treat high blood pressure may have a diuretic effect.To urinate more.

. Attention Deficit Medications If you take medications to treat conditions such as hyperactivity or impulsivity, the caffeine in coffee may enhance the effects of the medication, which may reduce its effectiveness in your body.

. Cold Medicines Some cold medications contain stimulants. So if you plan to take a nap later, you should keep in mind that drinking coffee while taking some cold medications may make it harder for you to relax.

**Anticoagulant Medications** These medications are used to reduce blood clotting, and include aspirin, clopidogrel (Plavix), ibuprofen (Advil, Motrin, others), naproxen (Anaprox, Naprosyn, others), enoxaparin (Lovenox), and others. Health experts advise caution when taking them with coffee, as coffee can also slow blood clotting. Combining these medications with caffeine may increase the risk of bleeding and bruising.

**Birth control medications** Some examples of birth control medications include ethinyl estradiol, levonorgestrel, norethindrone, and others. Birth control pills can affect your body's ability to eliminate caffeine as quickly as usual, which can lead to jitteriness, headaches, increased heart rate, and other side effects when taken with coffee.

**Anti-seizure medications** Caffeine can decrease the effectiveness of some medications used to treat seizures, which can lead to more frequent seizures in some people. Medications that may be less effective when taken with caffeine include:

- Carbamazepine (Tegretol).

- Ethosuximide (Zarontin).

- Valproate.

Anxiety medications and sedatives include diazepam (Valium), lorazepam (Ativan), and alprazolam (Xanax). The caffeine in coffee can negatively affect the effectiveness of these tranquilizers and anti-anxiety medications, as these medications calm the central nervous system, while caffeine stimulates it.
