If you’ve been prescribed Proscar (finasteride) for an enlarged prostate or hair loss, you probably wonder what your body might do in response. The good news is most people tolerate the drug well, but a handful of side effects can show up, especially when you start or adjust the dose. Below we break down the most frequent complaints, the rarer ones you should keep an eye on, and simple steps to ease them.
Within the first few weeks, many users report a mild drop in sexual drive. You might feel less interested in sex, notice a slight decrease in the amount of ejaculate, or experience occasional difficulty getting an erection. These changes usually improve after a month or two, and lowering the dose can help.
Another frequent issue is a feeling of fatigue or low energy. Finasteride can affect hormone balance, and the result can be a subtle “tired” vibe even if you’re getting enough sleep. Staying hydrated, exercising a little each day, and eating a balanced diet often offset this.
Some people get a small increase in breast tenderness or notice a tiny lump. This is called gynecomastia and happens because finasteride blocks the conversion of testosterone to dihydrotestosterone (DHT). If the lump feels firm or grows, talk to your doctor right away.
Although uncommon, allergic reactions can pop up. Look for rash, itching, swelling of the face or throat, or trouble breathing. These signs need immediate medical attention.
There are reports of mood changes, such as depression or anxiety, after months of use. If you feel unusually down, irritable, or notice a shift in your mental health, let your healthcare provider know. Sometimes a dosage tweak or a short break resolves the issue.
In very rare cases, men have experienced a drop in PSA levels that masks early detection of prostate cancer. Your doctor should monitor PSA regularly, especially if you’re on Proscar for a long time.
Remember, side effects differ from person to person. The key is to stay aware, track any new symptoms, and keep the conversation open with your prescriber.
Start with the lowest effective dose. Many doctors begin with 1 mg daily for hair loss and 5 mg for prostate issues. If side effects appear, a slower titration can give your body time to adjust.
Maintain a healthy lifestyle. Regular exercise, especially strength training, helps balance hormones naturally. Adding zinc‑rich foods (like beans, nuts, and seeds) may also support testosterone levels.
Don’t skip follow‑up appointments. Blood tests, including PSA and hormone panels, let your doctor spot problems before they become big.
If sexual side effects bother you, talk about possible “drug holidays” where you pause the medication for a short period under medical supervision. Some men find this restores libido without losing the prostate benefits.
Lastly, keep a simple symptom diary. Write down when a side effect starts, how long it lasts, and anything that made it better or worse. This log speeds up the doctor’s ability to adjust treatment.
Proscar can be a game‑changer for both prostate health and hair thinning, but like any medication, it comes with trade‑offs. By knowing what to expect and acting early, you can enjoy the benefits while keeping uncomfortable side effects at bay.
