Minoxidil 10mg Tablets

Minoxidil is a direct-acting peripheral vasodilator that reduces elevated systolic and diastolic blood pressure by decreasing peripheral vascular resistance. It acts by opening ATP-sensitive potassium channels in vascular smooth muscle cells, leading to hyperpolarization and relaxation of the smooth muscle, primarily in arterioles. This vasodilation leads to a reflex increase in heart rate, stroke volume, and cardiac output, and increased renin secretion, which can lead to fluid and salt retention.

Before Taking This Medication: Important Information to Share with Your Doctor

It is essential to inform your doctor about the following conditions to ensure safe treatment:

Any allergies you have, including allergies to this medication, its components, or other substances. Be sure to describe the allergic reaction and its symptoms.
If you have been diagnosed with pheochromocytoma, a type of adrenal gland tumor.
If you have recently experienced a heart attack.
If you are breastfeeding, as you should not breastfeed while taking this medication.

This list is not exhaustive, and it is crucial to discuss all your medications (prescription, over-the-counter, natural products, and vitamins) and health conditions with your doctor and pharmacist. They will help you determine if it is safe to take this medication with your other treatments and health issues. Never start, stop, or adjust the dosage of any medication without consulting your doctor first.

It is essential to inform all your healthcare providers, including doctors, nurses, pharmacists, and dentists, that you are taking this medication.

When starting this medication, avoid driving and other activities that require alertness until you understand how it affects you. To minimize the risk of dizziness or fainting, get up slowly from a sitting or lying down position, and be cautious when climbing stairs.

Regular monitoring of your blood pressure and heart rate is crucial, as directed by your doctor. Before initiating this medication and during treatment, you will need to undergo heart checks, including an electrocardiogram (ECG). Discuss the details with your doctor.

Adhere to your doctor's recommendations for blood work and other laboratory tests. Weigh yourself daily and consult your doctor before using any over-the-counter (OTC) products that may increase blood pressure, such as cough or cold medications, diet pills, stimulants, non-steroidal anti-inflammatory drugs (NSAIDs) like ibuprofen or naproxen, and certain natural products or aids.

If you are pregnant or planning to become pregnant, inform your doctor. You will need to discuss the benefits and risks associated with using this medication during pregnancy to make an informed decision.

• Guanethidine (severe orthostatic hypotension)

• Other antihypertensives (additive hypotensive effects)
• Diuretics (may enhance hypotensive effect and fluid retention)

• Chest pain (new or worsening angina)
• Shortness of breath (dyspnea)
• Swelling of ankles, feet, or hands (edema)
• Rapid weight gain
• Dizziness or lightheadedness
• Palpitations
• Increased body hair growth (hypertrichosis)

Minoxidil is classified as Pregnancy Category C. It should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Animal studies have shown adverse effects on the fetus.

Minoxidil is excreted in human milk. Due to the potential for serious adverse reactions in breastfed infants, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.

Use in children is generally reserved for severe hypertension refractory to other treatments. Dosing is weight-based and requires careful titration and monitoring due to the potential for serious adverse effects, including pericardial effusion and fluid retention. Concomitant beta-blocker and diuretic therapy are essential.

No specific dose adjustment is generally required based on age alone, but elderly patients may be more sensitive to the hypotensive effects and fluid retention. Start with lower doses and titrate cautiously. Monitor closely for adverse effects and ensure adequate concomitant therapy (beta-blocker, diuretic).

• Minoxidil is a potent vasodilator and should almost always be used in combination with a beta-blocker (to prevent reflex tachycardia) and a loop diuretic (to prevent fluid retention and edema).
• The most common and bothersome side effect is hypertrichosis (excessive hair growth), which occurs in almost all patients and is reversible upon discontinuation.
• Patients should be closely monitored for signs of fluid retention, including daily weights and assessment for edema.
• Pericardial effusion, sometimes leading to tamponade, is a serious but rare side effect. Patients should be educated on symptoms like chest pain, shortness of breath, and fatigue.
• Initial titration should ideally be done in a hospital setting due to the potential for profound hypotension and other serious adverse effects.
• Minoxidil is typically reserved for severe, refractory hypertension due to its side effect profile.

• Hydralazine (another direct vasodilator, but less potent)
• Nitroprusside (IV, for hypertensive emergencies)
• Other classes of antihypertensives (e.g., ACE inhibitors, ARBs, calcium channel blockers, diuretics, beta-blockers) are typically tried first for hypertension.

If your symptoms or health issues persist or worsen, it's essential to contact your doctor for further guidance. To ensure your safety, never share your medication with others or take someone else's medication. Some medications may come with an additional patient information leaflet, so be sure to check with your pharmacist for more information. If you have any questions or concerns about this medication, don't hesitate to reach out to your doctor, nurse, pharmacist, or other healthcare provider. In the event of a suspected overdose, immediately call your local poison control center or seek medical attention. When seeking help, be prepared to provide details about the medication, including the amount taken and the time it happened, to facilitate prompt and effective treatment.
