Isotretinoin Side Effects: What to Look Out for
Common Skin Changes While Taking Isotretinoin
As you begin isotretinoin, one of the first changes you’ll likely notice is your skin becoming much drier and more sensitive. Many people experience chapped lips, flaky patches, and a feeling of tightness, especially on the face and around the mouth. Gentle moisturizers quickly become essential, and regular lip balm use is a must.
Other common issues include mild redness or irritation, making it feel like your skin is sunburned even on cloudy days. Breakouts can actually worsen temporarily in the first month. With time, these symptoms usually improve as your skin acclimates.
Skin Change | Typical Timeline |
---|---|
Dryness | Days to weeks |
Peeling & Flakiness | First month |
Redness/Irritation | First 2–4 weeks |
Mental Health: Mood Shifts and Warning Signs

Some people experience mood swings while taking isotretinoin; you might feel more irritated or sad than usual. These emotional shifts can sneak up quietly, making it hard to tell if they’re related to the medication. Friends or family might notice changes before you do, such as withdrawing from things you enjoy. Occasionally, more serious symptoms like persistent sadness or thoughts of self-harm can appear. It’s important not to ignore these signs and to talk with a healthcare provider if they arise.
Musculoskeletal Aches and Joint Pain Explained
Many people notice muscle stiffness or mild aches early in their isotretinoin treatment. These discomforts often affect the larger muscle groups or the lower back, especially after exercise. While it’s common to feel sore or achy, these symptoms are usually manageable with rest and gentle stretching. Occasionally, some individuals experience joint pain that can feel similar to overuse or mild arthritis. If the pain worsens or interferes with daily activities, it’s important to let your healthcare provider know promptly.
Eye and Vision Issues to Pay Attention to

When taking isotretinoin, some people notice their eyes start feeling unusually dry or irritated. This discomfort can lead to redness, a gritty sensation, or the urge to blink more often. Sometimes, these symptoms appear early in the course of treatment and may persist throughout. Alongside dryness, you might also develop increased sensitivity to bright light or experience blurred vision at times.
Another potential side effect is difficulty wearing contact lenses, as isotretinoin can reduce tear production. Regular use of lubricating eye drops may help, but persistent pain or sudden visual changes should not be ignored. Always mention any significant eye concerns to your healthcare provider promptly.
Digestive System Side Effects You Might Notice
Many people taking isotretinoin focus on its effects on the skin, but your digestive system may notice changes too. Some individuals experience mild symptoms, such as nausea or slight abdominal discomfort, which usually resolve as your body adjusts to the medication. Less common, but more serious, side effects could include persistent diarrhea, rectal bleeding, or yellowing of the skin and eyes—indicators that your liver may be affected.
To help keep track of possible gastrointestinal symptoms, jot down any new digestive issues you encounter. Staying hydrated and maintaining a balanced diet can also support your digestive health during treatment. Most side effects are manageable, but remaining attentive can help you spot problems early.
Potential Digestive Side Effect | What To Do |
---|---|
Nausea or stomach pain | Monitor; contact your doctor if it persists |
Diarrhea or rectal bleeding | Seek medical attention promptly |
Yellowing of skin/eyes | Call your doctor immediately |
Red Flags: When to Call Your Doctor Immediately
Imagine it’s the middle of the night, and you notice your lips bleeding or your skin suddenly erupting in painful blisters—don’t ignore these symptoms. Isotretinoin can rarely cause severe reactions, so new rashes, hives, or facial swelling deserve urgent medical attention. Another warning sign is severe headache with vision changes or persistent vomiting, which might indicate increased pressure in your brain. If you develop chest pain, shortness of breath, or experience dramatic mood swings, including thoughts of harming yourself, seek immediate help. Recognizing these signs early can prevent complications. Remember, no concern is too small when your health is at stake.
