For Cluster Headaches: This medication was originally prescribed for high blood pressure, but in higher doses has 99% eliminated my cluster headaches and helped with temper outbursts. A powerful, multi-purpose and inexpensive medication. |

For Muscle Spasm: I’ve been on the medication Tizanidine now for 2 years. It works great for my spasms neck and headache. As long as I take it with the other meds I’m prescribed with. Taking it alone is like taking a aspirin. I’ve had no side affects at all thus far. For Muscle Spasm: I have been taking Tizanidine for almost 4 years now. It has been a lifesaver for me & given me mobility again. HOWEVER, THE APOTEX CORP. BRAND OF TIZANIDINE IS A VERY DISAPPOINTING DISPLAY OF THEIR LACK OF QUALITY MEDICATIONS IN THIS AREA. HORRIBLY UNDER THE STANDARDS OF OTHER COMPANIES THAT SUPPLY THIS SAME MEDICATION. I'm better off drinking water than taking any Tizanidine supplied by this company |

For Cluster Headaches: I've been experiencing Chronic Cluster Headaches since 2005. I had no idea what was going on, and suffered for 3 years untreated and undiagnosed. After some internet sleuthing I was able to tell my doc what was going on. Fast forward to 2016. I take verapamil 180mg er twice a day. This treatment has worked almost without fail, until just recently. In the past I have had to take other meds in combination with the verapamil such as... Topamax, imatrex, magnesium, prednizone, and now lithium. None of these work for me, been having daily headaches again. I now have a sumatriptan injection I take when I feel one coming and it stops it within 10 minutes. I need help, please.
