Sometimes when you take a common drug, you may have a side effect. That is, the drug may cause some effect other than its intended one. When these side effects occur, they are called adverse reactions. (23)Whenever you have an adverse reaction, you should stop taking the drug right away. Ask your pharmacist whether he can suggest a drug that will relieve the symptoms but that will not cause the adverse reaction. If an adverse reaction to a drug is serious, consult your doctor for advice at once.
Drugs that are safe in the dosage stated on the label may be very dangerous in large dose. For example, aspirin is seldom thought of as dangerous, but there are many reports of accidental poisoning of young children who take too many aspirin pills as well as the possible development of Reye syndrome in children with flu. In adults, excessive used of some pain-killing drugs may cause serve kidney damage. Some drugs for relief of stomach upsets, when taken in excess, can perhaps cause serious digestive problems. You should never use any over-the-counter drug on a regular, continued basis, or in large quantities, except on your doctor’s advice. You could be suffering from a serious illness that needs a doctor’s care.
Each drug you take not only acts on the body but may also alter the effect of any other drug you are taking. Sometimes, this can cause dangerous or even fatal reactions. For example, aspirin increases the blood-thinning effects of drugs given to patients with heart disease. Therefore, a patient who has been taking such a drug may risk bleeding if her or she uses aspirin for a headache. Before using several drugs together you should ask your doctor and follow his advice. Your pharmacist can tell you whether certain drugs can safely be taken together.
(24)Alcohol may increase the effect of a drug—sleeping pills combine with alcohol to produce a sleepy feeling. When taking any drug, you should ask your doctor whether drinking alcohol could be dangerous in combination with the medicine.
Experts believe there is a relationship between adult abuse of legitimate medicines and the drug culture has swept our country. (25)You can do your shar to reduce the chances that your children will become part of the drug culture by treating all medicines with respect. Always let your children know that medicines and drugs should not be used carelessly.
