A morning cup of coffee is a habit without which many do not imagine their day. But few people think that coffee can affect the effectiveness of medicines. Studies have shown that caffeine changes the work of the gastrointestinal tract, accelerating digestion and affecting the absorption of active substances into the blood.
Experts warn that some medicines cannot be combined with coffee. Consider the most common examples.
1. Thyroid drugs
based on levothyroxine drugs are extremely sensitive to coffee. It reduces their assimilation by more than 50%. To avoid efficiency loss, you should wait at least 30 minutes after taking the medication before drinking coffee.
2. Colds for colds and allergies
antihistamines and anti -edema products in combination with caffeine can cause nervousness, palpitations and anxiety. Particularly dangerous combination of coffee with fexofenadine - this can cause excessive stimulation of the nervous system.
3. Diabetes drugs
can increase blood sugar. This means that coffee consumption in parallel with drugs against diabetes can reduce their effectiveness and disrupt glucose control.
4. Alzheimer's disease
Donepeesil, Rivastigmine and galantamine can interact with caffeine, causing side effects, including insomnia or stomach upset. The ability to penetrate the brain is also reduced.
5. Asthma preparations
bronchodilators used to relieve asthma attacks can in combination with coffee cause irritability, headache or aggravation.
6. Coffee antidepressants
are able to exacerbate the side effects of selective serotonin reuptake inhibitors. Patients may have insomnia, palpitations or anxiety.
7. Hypertension drug
caffeine may interfere with the complete absorption of drugs to reduce blood pressure, which reduces their effectiveness. As a result, blood pressure can remain elevated, despite treatment.
8. Melatonin
caffeine inhibits the effect of melatonin - a hormone that regulates sleep. If you take melatonin additives and consume coffee, their action will be much weaker.
What to do?
Experts advise not to drink coffee for at least 30-60 minutes after taking medication, and in some cases - longer. If you are taking multiple drugs on a permanent basis, consult your doctor about interaction with caffeine.
