Can dantrolene cause problems?
Along with their useful effects all medicines can cause unwanted side effects, which usually improve as your body adjusts to the new medicine. Speak with your doctor or pharmacist if any of the following side effects continue or become troublesome.
| Side-effects | What can I do if I experience this |
| Drowsiness, dizziness, tiredness | Make sure your reactions are normal before driving, operating machinery or doing any other jobs which could be dangerous if you were not fully alert. Avoid alcohol as it will increase any feelings of drowsiness. |
| Diarrhoea | Drink plenty of water to replace lost fluids. If severe diarrhoea occurs speak to your doctor as they may suggest you stop taking dantrolene for a while. |
| Constipation | Try to eat a well balanced diet containing plenty of fibre and drink 6 - 8 glasses of water each day. |
| Nausea | Eat little and often. Stick to simple foods such as dry toast. |
| Headache | Ask your pharmacist to recommend a suitable pain-killer. If headache continues speak with your doctor. |
| Skin rash | Avoid scrubbing your skin. Use a soap substitute. Leave the affected area exposed to the air as much as possible. |
