Spotting Medication Side Effects: Common Reactions and When to Seek Help

Medication side effects are any reactions to a drug that aren’t supposed to happen. They can happen as your body gets used to a new medicine or a change in dose. Side effects depend on the type of medicine, how much you take, and things like your age, health, and genetics.

• Some side effects are mild, like feeling tired or having an upset stomach.

• Others can be more noticeable or affect your daily life.

• Most side effects go away as your body gets used to the medicine.

• Side effects can start soon after you begin a medicine, after a dose change, or even after using it for a long time.

• Some people are more sensitive to certain medicines than others.

Types of Medication Side Effects

Here are some common side effects you might notice:

• Stomach Problems: Nausea, vomiting, diarrhea, constipation, or stomach pain. These can happen with antibiotics, painkillers, or iron pills.

• Sleepiness or Dizziness: Medicines like antihistamines (for allergies) and muscle relaxants can make you sleepy or dizzy.

• Headaches: Some medicines can cause headaches, especially if they affect blood pressure.

• Skin Reactions: Some drugs can cause rashes, itching, or make your skin more sensitive to sunlight.

• Heart Effects: Some medicines can make your heart beat faster or raise your blood pressure.

• Weight Changes: Some drugs can make you gain or lose weight or change your blood sugar, especially if you have diabetes.

Some people are more likely to have side effects:

• Kids and Teens: Young people’s bodies are still growing, so they may react differently to medicines.

• Older Adults: People over 65 may be more sensitive because their bodies process medicines more slowly.

• People with Health Problems: If you have conditions like diabetes, asthma, or kidney disease, you might be more likely to have side effects.

• Lifestyle Choices: Drinking alcohol, eating certain foods, or smoking can change how your body reacts to medicine.

• Genetics: Some people’s bodies handle medicines differently because of their genes.

If you have side effects, there are things you can do:

• Take Medicine with Food or at Bedtime: This can help with nausea or sleepiness.

• Drink Water: Staying hydrated can help with dry mouth, headaches, or dizziness.

• Eat Healthy Foods: Eating fiber can help with constipation. Probiotics may help with stomach problems from antibiotics.

• Avoid Alcohol and Caffeine: These can make some side effects worse.

When to Call a Doctor

You should talk to your doctor if:

• Side effects don’t go away or get worse.
