Medicines have benefits and some have risks. Always read the label and use only as directed. If symptoms persist or you have side effects see your health professional. Brands and generics both contain the same active ingredient(s) and are medically equivalent. Some brands are marketed under different names by the same manufacturing country depending on the country of origin.
Astralean (clenbuterol) is a potent stimulant. Originally prescribed to help with breathing disorders, it has since expanded into other fields. It is also widely used in veterinary medicine.
The medication's more common uses include as a:
Astralean influences a number of functions in the body, including:
Astralean is widely used as a performance-enhancer, though it is illegal to do so in the vast majority of areas and it is often tested for by sport authorities for both humans and animals. It is also illegal to administer Astralean to animals destined to be food.
Use in Breathing Disorders
Though somewhat uncommon in most areas, Astralean is used as-needed to alleviate breathing difficulties in patients with asthma or COPD. It is a potent and long-lasting stimulant, more so than albuterol and epinephrine, perhaps too potent for patients with mild to moderate breathing ailments.
Asthma or COPD patients new to Astralean should start with low doses of 20 to 40 mcg. This can be increased, if needed, up to 120 mcg. While it is used as-needed to abort breathing difficulties, it should not be used excessively; severe side effects are possible if too much is taken.
Unlike most asthma or COPD treatments, Astralean comes in tablets. This will delay significant relief for 15 to 30 minutes, but once the medication starts circulating through the body the breathing difficulties should be nearly or entirely eliminated.
Astralean can be used as a maintenance treatment as well, when asthma or COPD is likely to be a problem. For example, a patient with asthma visiting a friend who has animals likely to trigger asthma. A tablet can be taken about an hour prior to exposure to prevent symptoms from developing in the first place. Note, however, that this sort of use will become increasingly less effective the longer it is done; patients do develop tolerance to Astralean if used regularly.
Off-label uses are varied, depending on goals and individual variables. As off-label uses are not approved by regulatory agencies there are no widely-accepted dosage and administration guidelines.
However, all patients---including perfectly healthy adults---using this medication off-label are strongly advised to start with low doses of 10 to 20 mcg until effects are known. If any concerning side effects develop treatment will ideally stop, and dosage should certainly not be increased. Off-label patients are also strongly advised to avoid exceeding 120 mcg per day.
Tolerance to Astralean may build quickly if taken regularly, rendering it significantly less effective over time. Most patients find it beneficial to take periodic breaks for a few days or weeks, during which time tolerance will diminish, then resuming treatment as normal.
Plenty of fluids should be consumed over the course of treatment to prevent dehydration, which may worsen some side effects. Regularly eating bananas may ease muscle cramps, if experienced.
If used as directed in healthy adults, Astralean is unlikely to produce serious side effects. However, the medication can produce dangerous complications in individuals with certain preexisting conditions, and patients are not always aware they have these conditions. Heart conditions are a particular concern, but patients with any medical condition are advised to avoid this product without first speaking with a doctor.
Serious side effects are likely if the medication is abused (taking more than 120 mcg per day). It may also cause complications when mixed with other medications or supplements, particularly other stimulants.
Side effects include:
Again, used as directed side effects typically do not occur or are mild, and often stop occurring if the medication is taken for a few consecutive days. If any side effect becomes concerning, patients are advised to stop taking Astralean and, if necessary, seek medical attention.
This medication should not be used by pregnant or breastfeeding women.
