Even though medicines are meant to help with health problems, they can sometimes have side effects that you didn’t expect. Some of the most common medicines can make you feel bad or cause problems, like stomach problems, tiredness, or changes in your mood. This article talks about 10 common prescription drugs and the side effects you should be aware of while taking them. If you know about these possible risks, you can talk to your doctor about other options that will have less of an effect on your health.
1. Antibiotics

Antibiotics treat infections caused by bacteria but can throw off the balance of good bacteria in your gut. This might hurt your stomach, cause diarrhea, make you sick, or even give you yeast infections. Pay close attention to what your doctor says, and take probiotics to keep your gut healthy while getting treatment.
2. Antidepressants (SSRIs)

SSRIs, or selective serotonin reuptake inhibitors, are often prescribed to treat depression and anxiety. However, they can have side effects such as making you gain weight, feel tired, or have problems with your sexual function. Some people may also have mood swings or have trouble sleeping. Talk to your doctor about changing your dose or switching medications if side effects bother you.
3. Pain Relievers (NSAIDs)

NSAIDs, like aspirin or ibuprofen, are commonly used to treat pain, but they can irritate the lining of the stomach. Taking these medicines for a long time may also hurt the way your kidneys work. It’s best to use them in small amounts and with food to keep your stomach from getting upset.
4. Statins

People often take statins to lower their cholesterol, but for some people, they can cause muscle pain, tiredness, and liver damage. Statin users may also have digestive problems, such as bloating and the inability to go to the bathroom regularly. Regular blood tests and checkups can help you monitor any side effects and change your treatment as needed.
5. Antihistamines

People with allergies often take antihistamines to feel better, but the older versions of these drugs can make you sleepy, have a dry mouth, and blur your vision. In addition, they might mess up your brain, making it hard to remember things or focus. These side effects are less likely if you choose newer antihistamines that don’t make you sleepy.
6. Blood Pressure Medications (Beta-Blockers)

Beta-blockers treat heart problems and high blood pressure but can make you feel dizzy, tired, or have cold hands or feet. They can sometimes also change your mood, which can lead to anxiety or depression. Having your healthcare provider check on you regularly can help you deal with any side effects.
7. Diuretics

These drugs, which are also called “water pills,” can get rid of extra water and salt in your body, which leads to lower blood pressure. That said, they can make you thirsty, mess up your electrolytes, and make you go to the bathroom more often. If you do this, you might get dizzy, tired, or break out in cramps.
8. Corticosteroids

Corticosteroids, such as prednisone, are often given to people with conditions that affect their immune systems or cause inflammation. When you take corticosteroids for a long time, you may gain weight, get osteoporosis, and get more infections. Seeing your doctor for regular checkups can help you monitor these possible side effects and change your treatment as needed.
9. Proton Pump Inhibitors (PPIs)

Proton pump inhibitors (PPIs), which are used to treat heartburn and acid reflux, can lower the production of stomach acid. However, they may also make it harder for the body to absorb nutrients, leading to deficiencies in calcium, magnesium, and vitamin B12. Long-term use can also make you more likely to break bones and get infections. If you need to take PPIs for a long time, talk to your doctor about other options.
10. Antipsychotic Medications

People with schizophrenia or bipolar disorder are given antipsychotic drugs. These drugs can have side effects like making you sleepy, gaining weight, and changing your metabolism. Some people may also shake, have stiff muscles, or have trouble walking. Talk to your doctor about any new or worsening symptoms on a regular basis so they can change your medication if needed.
