Does Finasteride lower blood pressure? 

Does Finasteride lower blood pressure? 

No, Finasteride is not associated with lowering your blood pressure as a side effect. The medication did not affect blood pressure during clinical trials and is considered safe to be used in cardiac patients (1). 

However, long-term use of Finasteride may lower your blood pressure, a new study indicates, but the effects are not significant and they are not observed in short-term users. 

If you’re being treated with Finasteride for quite a while and you are concerned about your blood pressure, talk to your healthcare provider. Although it is not likely for Finasteride to dangerously decrease or increase your blood pressure, the drug may affect people differently. 

What side effects are common with Finasteride use?

Finasteride, although it does not affect blood pressure, is associated with some side effects (1,2). 

Common side effects of Finasteride may include:

  • Decreased sex drive or libido
  • Erectile dysfunction
  • Ejaculation disorders (such as decreased semen volume)
  • Breast enlargement or tenderness
  • Skin rash or itching

Rare side effects of Finasteride may include:

  • Allergic reactions, including rash, hives, or swelling of the face, lips, tongue, or throat
  • Testicular pain or swelling
  • Depressed mood or mental changes
  • Nipple discharge
  • Persistent difficulty achieving or maintaining an erection

It’s important to note that individual experiences with Finasteride may vary. If you have any concerns or experience any unexpected or severe side effects while taking Finasteride, it is recommended to consult with your healthcare provider.

What factors can contribute to low blood pressure while taking Finasteride?

Several factors can contribute to low blood pressure while taking Finasteride, including individual variations in how the body responds to the medication, interactions with other medications or substances, and underlying medical conditions. 

For example, individuals with pre-existing low blood pressure or conditions that affect blood pressure regulation may be more susceptible to experiencing low blood pressure as a side effect of Finasteride (1).

It is important to note that while low blood pressure can occur with Finasteride, it is not a common side effect. If you are experiencing symptoms such as dizziness, lightheadedness, or fainting, it is advisable to consult with your healthcare provider.

What to do if your blood pressure drops while taking Finasteride?

If you experience a drop in blood pressure while taking Finasteride, it is important to inform your healthcare provider about the drop in blood pressure and any accompanying symptoms you may be experiencing.

Make sure you regularly measure your blood pressure at home using a reliable blood pressure monitor. Keep a record of your readings and share them with your healthcare provider. This information will help them understand the pattern and severity of your blood pressure changes.

Furthermore, you should avoid sudden movements while you’re struggling with hypotension. When you stand up from sitting or lying down, do so slowly to minimize the risk of dizziness or lightheadedness. This can help prevent falls or accidents due to low blood pressure (3).

Remember, it is crucial to seek professional advice from your healthcare provider. Your doctor may adjust the dosage, suggest lifestyle modifications, or recommend further evaluations to manage your blood pressure effectively while taking Finasteride.
