Summary
Terazosin is used to treat high blood pressure, which is when the force of blood against artery walls is too high, and benign prostatic hyperplasia, which is an enlarged prostate causing urinary issues.
Terazosin works by blocking alpha-1 receptors, which are proteins that tighten blood vessels and muscles. This relaxation improves blood flow and urine flow, helping to lower blood pressure and relieve symptoms of an enlarged prostate.
The usual starting dose of Terazosin for adults is 1 mg taken once daily at bedtime. Your doctor may gradually increase the dose to 5 mg or even 10 mg daily, depending on your response and tolerance.
Common side effects of Terazosin include dizziness, headache, and fatigue, which is feeling very tired. These occur in less than 10% of people and are usually mild.
Terazosin can cause a sudden drop in blood pressure, especially when standing up, leading to dizziness or fainting. Avoid alcohol, as it can increase these risks. Do not take Terazosin if you are allergic to it or its ingredients.
Indications and Purpose
How does Terazosin work?
Terazosin works by blocking alpha-1 receptors in the body, which are proteins that cause blood vessels and muscles to tighten. By blocking these receptors, Terazosin relaxes blood vessels and muscles in the prostate and bladder. This relaxation improves blood flow and urine flow, helping to lower blood pressure and relieve symptoms of benign prostatic hyperplasia, which is an enlarged prostate. Think of it like loosening a tight knot, allowing things to flow more freely.
Is Terazosin effective?
Yes, Terazosin is effective for treating high blood pressure and benign prostatic hyperplasia, which is an enlarged prostate. It works by relaxing blood vessels and muscles in the prostate and bladder, improving blood flow and urine flow. Clinical studies show Terazosin effectively lowers blood pressure and reduces urinary symptoms in men with an enlarged prostate. Always follow your doctor's instructions and attend regular check-ups to monitor your condition and ensure the medication is working properly.
What is Terazosin?
Terazosin is a medication used to treat high blood pressure and benign prostatic hyperplasia, which is an enlarged prostate. It belongs to a class of drugs called alpha-blockers, which work by relaxing blood vessels and muscles in the prostate and bladder. This helps improve blood flow and urine flow. Terazosin is often used as a complementary addition to other therapies for these conditions. Always follow your doctor's instructions when taking this medication.
Directions for Use
For how long do I take Terazosin?
Terazosin is usually a long-term medication for managing ongoing health conditions like high blood pressure or benign prostatic hyperplasia, which is an enlarged prostate. You'll typically take Terazosin every day as a lifelong treatment unless your doctor suggests otherwise. Stopping this medication without medical advice could cause your conditions to worsen. How long you'll need this medication depends on your body's response, any side effects you experience, and changes in your overall health.
How do I dispose of Terazosin?
To dispose of Terazosin, bring unused medicines to a drug take-back program or collection site at a pharmacy or hospital. They will dispose of this medicine properly so it doesn't harm people or the environment. If you can't find a take-back program, you can throw most medicines in the trash at home. But first, take them out of their original containers, mix them with something undesirable like used coffee grounds, seal the mixture in a plastic bag, and throw it away.
How do I take Terazosin?
Take Terazosin as prescribed by your doctor, usually once daily at bedtime. This helps reduce the risk of dizziness or fainting, which can occur when standing up quickly. You can take it with or without food. Do not crush or chew the tablets. If you miss a dose, take it as soon as you remember unless it's close to your next dose. In that case, skip the missed dose. Do not double up on doses. Avoid alcohol, as it can increase the risk of side effects like dizziness.
How long does it take for Terazosin to start working?
Terazosin begins working in your body shortly after you take it, but it may take a few weeks to achieve its full therapeutic effect. For high blood pressure, you might notice improvements in blood pressure readings within a few days. For benign prostatic hyperplasia, it may take several weeks to see significant changes in urine flow and symptoms. Individual factors like age, kidney function, and overall health can affect how quickly the medication works. Take it exactly as prescribed for the best results.
How should I store Terazosin?
Store Terazosin at room temperature, away from moisture and light. Keep it in a tightly closed container to protect it from damage. Avoid storing it in humid places like bathrooms, where moisture in the air could affect how well the medication works. Always store Terazosin out of children's reach to prevent accidental swallowing. Remember to check the expiration date regularly and properly dispose of any unused or expired medication.
What is the usual dose of Terazosin?
The usual starting dose of Terazosin for adults is 1 mg taken once daily at bedtime. Your doctor may gradually increase the dose to 5 mg or even 10 mg daily, depending on your response and tolerance.

Always follow your doctor's specific dosing instructions for your health needs.

For example, taking it with other blood pressure medications can cause a significant drop in blood pressure, leading to dizziness or fainting.

If you're taking Terazosin and want to breastfeed, talk with your doctor about safer medication options that would allow you to nurse your baby safely.
Can Terazosin be taken safely while pregnant?
The safety of Terazosin during pregnancy is not well-established. Limited evidence makes it difficult to provide definitive advice about its safety.

Not following these warnings can lead to falls or injuries. Always follow your doctor's advice and report any concerning symptoms.
Is it safe to drink alcohol while taking Terazosin?
It's best to avoid alcohol while taking Terazosin. Alcohol can increase the risk of side effects like dizziness or fainting, especially when standing up quickly.

Talk with your doctor about alcohol use while taking Terazosin to get personalized advice.
Is it safe to exercise while taking Terazosin?

These symptoms might be more noticeable during exercise. To exercise safely, drink plenty of water before, during, and after physical activity. Watch for signs of dizziness or unusual fatigue. If you notice these symptoms, slow down or stop exercising and rest. Check with your doctor if you have concerns about your specific situation.
Is it safe to stop Terazosin?
It's important to talk to your doctor before stopping Terazosin. This medication is often used long-term for conditions like high blood pressure or benign prostatic hyperplasia, which is an enlarged prostate. Stopping suddenly can cause your condition to worsen or lead to a rapid increase in blood pressure. Your doctor may suggest gradually reducing your dose to avoid potential risks. Always follow your doctor's guidance to ensure your health is protected.
Is Terazosin addictive?
No, Terazosin is not addictive or habit-forming. It does not cause dependency or withdrawal symptoms when you stop taking it.
