How to Reduce The Side Effects of Finasteride

Finasteride is generally well tolerated in males, but side effects can occur.

These simple tips and habits can help manage the side effects of finasteride and make treatment more comfortable.

Start with a lower dosage (if clinically appropriate)

Sometimes finasteride is tolerated better by taking it every other day or 3–4 times per week at first. Our clinical team may recommend gradually increasing to daily use once your body adjusts.

Do not double dose

Taking more finasteride than prescribed can be harmful to your health.

Even if you miss a dose, skip it and continue taking finasteride as per your normal routine.

Use finasteride as prescribed

It’s important to take your treatment exactly as your prescriber instructs. Taking more than recommended won’t speed up results and can increase the risk of side effects.

Staying on the prescribed dose helps your body adjust safely and keeps hormone levels balanced.

Switch to topical finasteride

If side effects continue, topical finasteride may be recommended. It mainly works on the scalp and limits how much of the medication enters the rest of the body, helping reduce the risk of sexual or mood-related side effects.

Review other medications

A pharmacist may check for medicines or supplements that affect hormones, mood, or sexual function, as these can amplify side effects. Adjusting these may help.

Trial a treatment break (clinician supervised)

In some cases, a short, supervised break may be suggested to see if symptoms improve, then reintroduce treatment slowly.

This allows your clinician to identify the likelihood of side effects being directly attributed to Finasteride.

Consider alternative treatments

If side effects remain bothersome, a clinician may suggest alternatives such as:

Minoxidil (topical or oral)
Dutasteride (stronger, but may not suit everyone)
Low-level laser therapy
PRP (platelet-rich plasma)

Regular monitoring and follow-up

Scheduled check-ins help assess side effects early and allow adjustments to dose, frequency, or formulation before symptoms worsen.

Small lifestyle changes can make a real difference when taking finasteride.

Simple habits around sleep, stress, exercise, and alcohol intake may help reduce side effects and support how your body adjusts to treatment.

Keep a consistent routine

Take finasteride at the same time each day. Regular use helps your body adjust and can reduce the chance of side effects.

Fuel your body well

A healthy, well-balanced diet can support energy, mood, and overall wellbeing while on treatment.

Aim for regular meals with a good mix of protein, fibre, and healthy fats to help keep blood sugar steady and reduce digestive side effects.

Staying well hydrated and limiting very fatty, sugary, or highly processed foods may also help you feel more comfortable, especially in the early weeks.

Keep moving

Regular physical activity can help maintain muscle strength, support mood, and improve circulation while taking finasteride.

Exercise is also beneficial for overall hormonal balance, heart health, and energy levels.

Even gentle, consistent movement such as walking, stretching, or light resistance training can make a positive difference, there’s no need to overdo it.

Take time to unwind

Stress can make side effects like mood changes feel worse. Try relaxation techniques, light exercise, or hobbies that help you unwind.

Get enough sleep

Good-quality sleep helps your body regulate hormones and supports both mental and physical health.

A consistent sleep routine can reduce fatigue, improve concentration, and help manage irritability or low mood while on finasteride. Aiming for regular bedtimes and a calm wind-down routine can make a real difference.

Limit alcohol if sensitive

Some men find that alcohol can worsen changes in mood, energy, or sleep while taking finasteride.

If you notice this, reducing your intake or avoiding alcohol altogether may help minimise side effects and support overall wellbeing.

Monitor how you feel

Pay attention to any changes in mood, energy levels, or sexual function while taking finasteride. Keeping a simple note of symptoms can be helpful.

If anything feels concerning or persistent, speaking to a pharmacist or doctor early can help address side effects and explore your options.
